Yeah, I replaced the title string with regular text and it did get changed in the Settings app, so I'm pretty sure that's the xml I need to work with.
Have you tried just deleting the lines? There aren't any id's in them so there shouldn't be any issue.
Probably.
I'm gonna go ahead and laugh here because the simplest and more dangerous solution ended up being the correct one
Yeah there were no issues (at least, so far)
Thanks, sometimes we just need to go to square one lol
You're the best!

If you're modding Android, eventually you're going to have to edit some XML.
Want to center the clock in your statusbar? Rearrange the icons in your navbar? Change the layout of your notification screen? Get rid of a carrier label? Change the colour of some text?
Then you need to edit some XML files.
And you might not have any idea how...
Well, don't worry. The purpose of this thread is to show you just easy XML-editing can be. Once you've read it, you'll be one step closer to being an XML expert!
This guide is meant for noobs, experienced modders and everyone in between. Hopefully everybody can learn something..

*** What Is XML? ***
'XML' stands for 'eXtensible Markup Language'. But you don't need to know that.
What you need to know is that XML is used by Google to define the layout of Android applications.
Look at your statusbar. It's Java that controls how your statusbar works, but it's XML that controls where everything on it is.
(If you want to edit the Java, you can try building the app from source. Or look at editing smali. Smali is harder to understand than XML but there's a great guide by @Goldie here: http://xdaforums.com/galaxy-s2/development-derivatives/guide-understanding-creating-smali-mods-t2488033)
*** Where Can I Find An App's XML? ***
To edit an app's XML, you first need to be able to access it. To do that, you need to decompile the .apk file. If you don't decompile, any XML you try editing won't work.
There are enough tutorials on xda to tell you how to do this that I don't need to fill up space here telling you about it.
But I always recommend using Tickle My Android (http://xdaforums.com/showthread.php?t=1633333) for any decompiling and recompiling.
*** What Does XML Look Like? ***
This is the line of XML that displays the clock on my phone's statusbar:
Code:<com.android.systemui.statusbar.policy.Clock android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="start|center" android:id="@id/clock" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" android:paddingStart="6.0dip" />
One of the great things about XML is that it ignores whitespace. Or, in other words, we can do stuff like this:
Code:<com.android.systemui.statusbar.policy.Clock android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="start|center" android:id="@id/clock" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" android:paddingStart="6.0dip" />
Looks a bit more sensible, doesn't it? In theory, you can do this to every single line in a XML file but that'd be time-consuming and a bit pointless.
XML consists of two parts: 'tags' and 'attributes'. Google also like to talk about 'Views' and 'ViewGroups', but we won't worry about that for now.
Essentially, a tag is something you see (even if it's invisible) and an attribute affects the way that tag works. Let's look at that code again with the tags and attributes highlighted..
Code:[color="red"]<com.android.systemui.statusbar.policy.Clock [color="blue"] android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="start|center" android:id="@id/clock" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" android:paddingStart="6.0dip"[/color] />[/color]
Hopefully that code is starting to make a bit more sense. If not, don't worry. The more you edit XML, the more you'll understand it.
We can change those attributes, remove some and add others. And at the end of it all, that clock can look completely different.
And that's before we start moving the line to somewhere else in the XML file and adding other tags. With a little work, and a little patience, we can make a massive difference to our Android device.
*** What Do I Need To Know To Start Modding XML Myself? ***

If you understand every single line, tag and attribute then you can skip the next three posts. You're clearly an expert and I should probably be calling you 'Sir'...
If you don't, then read on. Hopefully you can see that, even though there's a lot of code there, it's all just tags and attributes. That's all that XML is. It's easier than it looks.
I have a few more things to tell you, then I'll show you a few example mods. Then it'd be time for you to practice editing XML for yourself.45*** How To Delete A Line (Yes, Really) ***
That's right.
I'm dedicating an entire post to teach you how to use the DELETE button.
I'm nuts, right?
Actually...no. (Although my therapist would disagree!)

No.
Try this and as soon as Android tries to run your modified apk, it'll FC. Even if that's the only change that you've made to it.
Why?
Well, it's not because you deleted the status icon line...it's because you deleted the line's 'id'
Let's have another look at the status icon line:
Code:<ImageView android:layout_gravity="center_vertical" [color="red"]android:id="@id/status"[/color] android:layout_width="wrap_content" android:layout_height="wrap_content" />
Some of these attributes we'll discuss later, the one we're concerned with right now is 'android:id="@id/status"'
The attribute 'android:id' is used as a reference. Sometimes they just provide a reminder of what the line does, sometimes they are used by the apk's Java code.
We've deleted the reference to the status icons, but not the Java/smali code that defines which icons should be shown.
The apk will run, work out which status icons to show, can't find where they should go, report an error and Android will force the app to close.
Which is annoying.
There are three ways we can fix this and stop the status icons from showing without the app FC'ing on us:
1. We could work out what the hex reference is that's associated with that id, track it through the smali and edit the code as needed. Which is a lot of work. A lot of work.
2. We could try to make the status icons invisible by setting their height and width to 0.
This works but isn't ideal. Android is still using processing time and power to show those icons, we just can't see them. We're only talking about a handful of icons on the statusbar and the difference in the drain on the processor is negligible, but it's still not best practice.Code:<ImageView android:layout_gravity="center_vertical" android:id="@id/status" android:layout_width="[color="red"]0.0dip[/color]" android:layout_height="[color="red"]0.0dip[/color]" />
3. We can change the lines 'visibility by adding a new attribute..
This makes Android ignore this line completely. It's not visible to us because Android just doesn't bother drawing it.Code:<ImageView [color="red"]android:visibility="gone"[/color] android:layout_gravity="center_vertical" android:id="@id/status" android:layout_width="wrap_content" android:layout_height="wrap_content" />
Setting the height and width to 0 isn't the best solution for hiding something but there are times when changing the visibility doesn't work. You may find lines of XML that already have 'android:visibility="gone"' in them. Some ROM's have the option to hide/show certain parts of their UI while running.
So a line with 'android:visibility="gone"' can be forced to become visible. Changing the height and width to zero stops it from ever becoming visible.
If the last paragraph didn't really make sense, don't worry about it. For most of the mods you're likely to do, you can use either option 2 or option 3 to stop things from showing. It's up to you.
Basically, if you want to remove a line with an 'android:id' attribute in it..
Don't Delete It...Hide It!32*** How To Center The Clock In The Status Bar...Part 2 ***
So how do we fix this issue of the overlapping notifications with the Simple Method?
With the Best Method, of course!
*** The Best Method ***
This is a bit more involved but is the very best way to center the clock.
Or anything else.
In fact, it's a brilliant way to arrange your status bar so you can move anything anywhere.
The Best Method splits the @id/icons Layout into three unique areas, making it very easy to decide what you want where.
What we do is we use this basic arrangement:
Code:<LinearLayout android:orientation="horizontal" android:id="@id/icons" android:paddingLeft="6.0dip" android:paddingRight="6.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:id="@+id/Status_Bar_Left_Side" android:orientation="horizontal" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0"> [COLOR="Red"]<!-- HERE ARE ALL THE CODES FOR THE ITEMS ON THE LEFT SIDE OF THE STATUSBAR -->[/COLOR] </LinearLayout> [COLOR="Red"]<!-- HERE ARE ALL THE CODES FOR THE ITEMS IN THE CENTER OF THE STATUSBAR -->[/COLOR] <RelativeLayout android:id="@+id/Status_Bar_Right_Side" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0"> <LinearLayout android:id="@+id/Inside_Status_Bar_Right_Side" android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentRight="true"> [COLOR="red"]<!-- HERE ARE ALL THE CODES FOR THE ITEMS ON THE RIGHT SIDE OF THE STATUSBAR -->[/COLOR] </LinearLayout> </RelativeLayout> </LinearLayout>
Make sense? No? Well, don't worry. There is a logic behind all this. Even if it's not obvious.
This Method basically divides the status bar into just two individual areas. Because those areas have the same 'weight' as each other, they take up exactly the same amount of space as each other. Meaning that whatever goes between those two areas, as long as it doesn't have a weight of 1 or more, will be essentially pushed into the exact center of the status bar.
So, what we do next is apply this Method to our code from above to create:
Code:[color="red"]<LinearLayout android:orientation="horizontal" android:id="@id/icons" android:paddingLeft="6.0dip" android:paddingRight="6.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent">[/color] <LinearLayout android:id="@+id/Status_Bar_Left_Side" android:orientation="horizontal" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0"> [color="red"]<LinearLayout android:orientation="horizontal" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0"> <com.android.systemui.statusbar.StatusBarIconView android:id="@id/moreIcon" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:visibility="gone" android:src="@drawable/stat_notify_more" /> <com.android.systemui.statusbar.phone.IconMerger android:orientation="horizontal" android:id="@id/notificationIcons" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center_vertical" android:layout_alignParentLeft="true" /> </LinearLayout>[/color] </LinearLayout> [color="red"]<com.android.systemui.statusbar.policy.Clock android:id="@id/clock" android:layout_width="wrap_content" android:layout_height="fill_parent" android:gravity="center" android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:singleLine="true"/>[/color] <RelativeLayout android:id="@+id/Status_Bar_Right_Side" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0"> <LinearLayout android:id="@+id/Inside_Status_Bar_Right_Side" android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentRight="true"> [color="red"]<LinearLayout android:orientation="horizontal" android:id="@id/statusIcons" android:layout_width="wrap_content" android:layout_height="fill_parent" android:gravity="center_vertical" /> <ImageView android:id="@id/stat_no_sim" android:paddingLeft="4.0dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:visibility="gone" android:layout_gravity="center_vertical" /> <LinearLayout android:orientation="horizontal" android:id="@id/signal_battery_cluster" android:paddingLeft="2.0dip" android:layout_width="wrap_content" android:layout_height="fill_parent" android:gravity="center"> <include android:id="@id/signal_cluster" android:layout_width="wrap_content" android:layout_height="wrap_content" layout="@layout/signal_cluster_view" /> <ImageView android:id="@id/battery" android:paddingLeft="8.0dip" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>[/color] </LinearLayout> </RelativeLayout> [color="red"]</LinearLayout>[/color]
The original code is in red. The only real challenge with this Method is knowing what lines to put in the @id/Status_Bar_Left_Side Layout and which lines to put in the @id/Status_Bar_Right_Side Layout. But take your time, look at the attributes (especially the @id attributes) and it should all become clear.
See? Doesn't that just look beautiful?
And so easy to do as well!
*** The Best Method...On KitKat And Lollipop ***
When I came up with the Best Method, Google were only just getting ready to give the world Jelly Bean.
It's two years later and the XML has changed a bit. This is what the stock KitKat status_bar.xml looks like:
Code:<com.android.systemui.statusbar.phone.PhoneStatusBarView android:id="@+id/status_bar" android:background="@drawable/system_bar_background" android:orientation="vertical" android:focusable="true" android:descendantFocusability="afterDescendants" android:fitsSystemWindows="true" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:systemui="http://schemas.android.com/apk/res/com.android.systemui"> <ImageView android:id="@+id/notification_lights_out" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="match_parent" android:paddingStart="6dip" android:paddingBottom="2dip" android:src="@drawable/ic_sysbar_lights_out_dot_small" android:scaleType="center" android:visibility="gone" /> <LinearLayout android:id="@+id/status_bar_contents" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingStart="6dip" android:paddingEnd="6dip" android:orientation="horizontal" > <LinearLayout android:id="@+id/notification_icon_area" android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="1" android:orientation="horizontal" > <com.android.systemui.statusbar.StatusBarIconView android:id="@+id/moreIcon" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="match_parent" android:src="@drawable/stat_notify_more" android:visibility="gone" /> <com.android.systemui.statusbar.phone.IconMerger android:id="@+id/notificationIcons" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_alignParentStart="true" android:gravity="center_vertical" android:orientation="horizontal"/> </LinearLayout> <LinearLayout android:id="@+id/system_icon_area" android:layout_width="wrap_content" android:layout_height="match_parent" android:orientation="horizontal"> <LinearLayout android:id="@+id/statusIcons" android:layout_width="wrap_content" android:layout_height="match_parent" android:gravity="center_vertical" android:orientation="horizontal"/> <LinearLayout android:id="@+id/signal_battery_cluster" android:layout_width="wrap_content" android:layout_height="match_parent" android:paddingStart="2dp" android:orientation="horizontal" android:gravity="center" > <include layout="@layout/signal_cluster_view" android:id="@+id/signal_cluster" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <com.android.systemui.BatteryMeterView android:id="@+id/battery" android:layout_height="16dp" android:layout_width="10.5dp" android:layout_marginBottom="0.33dp" android:layout_marginStart="4dip" /> </LinearLayout> <com.android.systemui.statusbar.policy.Clock android:id="@+id/clock" android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:layout_width="wrap_content" android:layout_height="match_parent" android:singleLine="true" android:paddingStart="6dip" android:gravity="center_vertical|start" /> </LinearLayout> </LinearLayout> <LinearLayout android:id="@+id/ticker" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingStart="6dip" android:animationCache="false" android:orientation="horizontal" > <ImageSwitcher android:id="@+id/tickerIcon" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="@dimen/status_bar_icon_size" android:layout_marginEnd="4dip" > <com.android.systemui.statusbar.AnimatedImageView android:layout_width="@dimen/status_bar_icon_size" android:layout_height="@dimen/status_bar_icon_size" android:scaleType="center" /> <com.android.systemui.statusbar.AnimatedImageView android:layout_width="@dimen/status_bar_icon_size" android:layout_height="@dimen/status_bar_icon_size" android:scaleType="center" /> </ImageSwitcher> <com.android.systemui.statusbar.phone.TickerView android:id="@+id/tickerText" android:layout_width="0dip" android:layout_weight="1" android:layout_height="wrap_content" android:paddingTop="2dip" android:paddingEnd="10dip"> <TextView android:textAppearance="@style/TextAppearance.StatusBar.PhoneTicker" android:layout_width="match_parent" android:layout_height="wrap_content" android:singleLine="true" /> <TextView android:textAppearance="@style/TextAppearance.StatusBar.PhoneTicker" android:layout_width="match_parent" android:layout_height="wrap_content" android:singleLine="true" /> </com.android.systemui.statusbar.phone.TickerView> </LinearLayout> </com.android.systemui.statusbar.phone.PhoneStatusBarView>
It looks similar to the code at the top of this post but there are significant differences. The @id/icons Layout has been replaced with a @id/status_bar_contents Layout which looks a lot more complex.
But it isn't, really. We can still use the Best Method on it. And it's actually quite easy to do.
The Best Method splits the status bar into two individual areas. The @id/status_bar_contents Layout splits the status bar into two individual areas.
Half the work is done for us.
We just need to make four very simple changes..
Code:<com.android.systemui.statusbar.phone.PhoneStatusBarView android:id="@+id/status_bar" android:background="@drawable/system_bar_background" android:orientation="vertical" android:focusable="true" android:descendantFocusability="afterDescendants" android:fitsSystemWindows="true" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:systemui="http://schemas.android.com/apk/res/com.android.systemui"> <ImageView android:id="@+id/notification_lights_out" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="match_parent" android:paddingStart="6dip" android:paddingBottom="2dip" android:src="@drawable/ic_sysbar_lights_out_dot_small" android:scaleType="center" android:visibility="gone" /> <LinearLayout android:id="@+id/status_bar_contents" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingStart="6dip" android:paddingEnd="6dip" android:orientation="horizontal" > <LinearLayout android:id="@+id/notification_icon_area" android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="1" android:orientation="horizontal" > <com.android.systemui.statusbar.StatusBarIconView android:id="@+id/moreIcon" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="match_parent" android:src="@drawable/stat_notify_more" android:visibility="gone" /> <com.android.systemui.statusbar.phone.IconMerger android:id="@+id/notificationIcons" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_alignParentStart="true" android:gravity="center_vertical" android:orientation="horizontal"/> </LinearLayout> [color="red"] <com.android.systemui.statusbar.policy.Clock android:id="@+id/clock" android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:layout_width="wrap_content" android:layout_height="match_parent" android:singleLine="true" android:gravity="center_vertical|start" />[/color] <LinearLayout android:id="@+id/system_icon_area" [color="red"]android:layout_width="0dip" android:layout_weight="1"[/color] android:layout_height="match_parent" android:orientation="horizontal"> [color="red"]<View android:visibility="invisible" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0" />[/color] <LinearLayout android:id="@+id/statusIcons" android:layout_width="wrap_content" android:layout_height="match_parent" android:gravity="center_vertical" android:orientation="horizontal"/> <LinearLayout android:id="@+id/signal_battery_cluster" android:layout_width="wrap_content" android:layout_height="match_parent" android:paddingStart="2dp" android:orientation="horizontal" android:gravity="center" > <include layout="@layout/signal_cluster_view" android:id="@+id/signal_cluster" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <com.android.systemui.BatteryMeterView android:id="@+id/battery" android:layout_height="16dp" android:layout_width="10.5dp" android:layout_marginBottom="0.33dp" android:layout_marginStart="4dip" /> </LinearLayout> </LinearLayout> </LinearLayout> <LinearLayout android:id="@+id/ticker" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingStart="6dip" android:animationCache="false" android:orientation="horizontal" > <ImageSwitcher android:id="@+id/tickerIcon" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="@dimen/status_bar_icon_size" android:layout_marginEnd="4dip" > <com.android.systemui.statusbar.AnimatedImageView android:layout_width="@dimen/status_bar_icon_size" android:layout_height="@dimen/status_bar_icon_size" android:scaleType="center" /> <com.android.systemui.statusbar.AnimatedImageView android:layout_width="@dimen/status_bar_icon_size" android:layout_height="@dimen/status_bar_icon_size" android:scaleType="center" /> </ImageSwitcher> <com.android.systemui.statusbar.phone.TickerView android:id="@+id/tickerText" android:layout_width="0dip" android:layout_weight="1" android:layout_height="wrap_content" android:paddingTop="2dip" android:paddingEnd="10dip"> <TextView android:textAppearance="@style/TextAppearance.StatusBar.PhoneTicker" android:layout_width="match_parent" android:layout_height="wrap_content" android:singleLine="true" /> <TextView android:textAppearance="@style/TextAppearance.StatusBar.PhoneTicker" android:layout_width="match_parent" android:layout_height="wrap_content" android:singleLine="true" /> </com.android.systemui.statusbar.phone.TickerView> </LinearLayout> </com.android.systemui.statusbar.phone.PhoneStatusBarView>
I've highlighted three of those four changes in red. The fourth you can't see as I just deleted the androidaddingStart="6dip" attribute from the clock line, to keep the clock centered.
The View line pushes the contents of the @id/system_icon_area Layout to the far right of the screen. The contents of the other Layout are already on the far left of the screen. So what's between should be in the center..
So that's KitKat, but what about Android 5.0? What about Lollipop?
Well, this is the stock Lollipop status_bar.xml:
Code:<?xml version="1.0" encoding="utf-8"?> <com.android.systemui.statusbar.phone.PhoneStatusBarView android:orientation="vertical" android:id="@id/status_bar" android:background="@drawable/system_bar_background" android:focusable="true" android:descendantFocusability="afterDescendants" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:systemui="http://schemas.android.com/apk/res/com.android.systemui"> <ImageView android:id="@id/notification_lights_out" android:paddingBottom="2.0dip" android:visibility="gone" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:src="@drawable/ic_sysbar_lights_out_dot_small" android:scaleType="center" android:paddingStart="6.0dip" /> <LinearLayout android:orientation="horizontal" android:id="@id/status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingStart="6.0dip" android:paddingEnd="8.0dip"> <com.android.systemui.statusbar.AlphaOptimizedFrameLayout android:orientation="horizontal" android:id="@id/notification_icon_area" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0"> <com.android.keyguard.AlphaOptimizedLinearLayout android:id="@id/notification_icon_area_inner" android:layout_width="fill_parent" android:layout_height="fill_parent"> <com.android.systemui.statusbar.StatusBarIconView android:id="@id/moreIcon" android:visibility="gone" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:src="@drawable/stat_notify_more" /> <com.android.systemui.statusbar.phone.IconMerger android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/notificationIcons" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentStart="true" /> </com.android.keyguard.AlphaOptimizedLinearLayout> </com.android.systemui.statusbar.AlphaOptimizedFrameLayout> <com.android.keyguard.AlphaOptimizedLinearLayout android:orientation="horizontal" android:id="@id/system_icon_area" android:layout_width="wrap_content" android:layout_height="fill_parent"> <include layout="@layout/system_icons" /> <com.android.systemui.statusbar.policy.Clock android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="start|center" android:id="@id/clock" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" android:paddingStart="7.0dip" /> </com.android.keyguard.AlphaOptimizedLinearLayout> </LinearLayout> <ViewStub android:id="@id/ticker_stub" android:layout="@layout/status_bar_ticker" android:inflatedId="@id/ticker" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </com.android.systemui.statusbar.phone.PhoneStatusBarView>
Look closely and you'll notice that the @id/status_bar_contents Layout is still just divided into two areas: @id/notification_icon_area and @id/system_icon_area.
Adding the Best Method to that shouldn't be a problem at all...
Code:<?xml version="1.0" encoding="utf-8"?> <com.android.systemui.statusbar.phone.PhoneStatusBarView android:orientation="vertical" android:id="@id/status_bar" android:background="@drawable/system_bar_background" android:focusable="true" android:descendantFocusability="afterDescendants" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:systemui="http://schemas.android.com/apk/res/com.android.systemui"> <ImageView android:id="@id/notification_lights_out" android:paddingBottom="2.0dip" android:visibility="gone" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:src="@drawable/ic_sysbar_lights_out_dot_small" android:scaleType="center" android:paddingStart="6.0dip" /> <LinearLayout android:orientation="horizontal" android:id="@id/status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingStart="6.0dip" android:paddingEnd="8.0dip"> <com.android.systemui.statusbar.AlphaOptimizedFrameLayout android:orientation="horizontal" android:id="@id/notification_icon_area" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0"> <com.android.keyguard.AlphaOptimizedLinearLayout android:id="@id/notification_icon_area_inner" android:layout_width="fill_parent" android:layout_height="fill_parent"> <com.android.systemui.statusbar.StatusBarIconView android:id="@id/moreIcon" android:visibility="gone" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:src="@drawable/stat_notify_more" /> <com.android.systemui.statusbar.phone.IconMerger android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/notificationIcons" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentStart="true" /> </com.android.keyguard.AlphaOptimizedLinearLayout> </com.android.systemui.statusbar.AlphaOptimizedFrameLayout> <com.android.systemui.statusbar.policy.Clock android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="start|center" android:id="@id/clock" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" /> <com.android.keyguard.AlphaOptimizedLinearLayout android:orientation="horizontal" android:id="@id/system_icon_area" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0" > <View android:visibility="invisible" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0" /> <include layout="@layout/system_icons" /> </com.android.keyguard.AlphaOptimizedLinearLayout> </LinearLayout> <ViewStub android:id="@id/ticker_stub" android:layout="@layout/status_bar_ticker" android:inflatedId="@id/ticker" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </com.android.systemui.statusbar.phone.PhoneStatusBarView>
Now, we're nearly there but there's still work to be done.
In Lollipop, the clock on the status bar isn't shown when the device is locked. There's not much need for it when you have a bigger clock on the lockscreen anyway. But, when we move the clock to get it centered, the clock doesn't disappear. It's always visible.
To make the clock vanish when the device is locked, you'll need to do a smali mod. Have a look at this post by @S0bes to see what to do: http://xdaforums.com/showpost.php?p=58460343&postcount=172

One final thing...ALWAYS MAKE A BACKUP!!!
25*** android:layout_gravity, android:gravity AND android:layout_weight ***
Centering the clock in the previous two posts wouldn't have been possible without using two particular attributes: 'android:gravity' and 'android:layout_weight'.
In physics, weight is the result of gravity acting on mass. But this isn't physics, it's Android, so what do these attributes actually mean?
*** GRAVITY ***
In Android, the gravity of an object changes how it's laid out in the space it occupies.
Let's have a few practical examples to better explain..
Here's a blank status bar.
Let's add a simple clock to it.
Code:<com.android.systemui.statusbar.policy.Clock android:id="@id/clock" android:background="#ff33b5e5" android:textColor="#ffffffff" android:layout_width="wrap_content" android:layout_height="fill_parent" />
I've missed a few attributes that you'd normally find in a real XML file, just to keep it simple. But I have added an attribute that sets the background colour to Holo Blue Light. You'll see how useful that is as I continue..
Here's my status bar now.
(DISCLAIMER: This isn't a real status bar. It's just something I put together in a picture-editing program on my PC. Doing these images with a real status bar would take forever...)
Let's add a gravity attribute to get this clock centered..
Code:<com.android.systemui.statusbar.policy.Clock android:id="@id/clock" [COLOR="Red"] android:gravity="center"[/COLOR] android:background="#ff33b5e5" android:textColor="#ffffffff" android:layout_width="wrap_content" android:layout_height="fill_parent" />
This gives us this..
That didn't work. The android:gravity attribute changes how an object is laid out, but only in its own space. The clock is now centered in that space, but not the statusbar.
So let's expand that space.
Code:<com.android.systemui.statusbar.policy.Clock android:id="@id/clock" android:background="#ff33b5e5" android:textColor="#ffffffff" [COLOR="Red"] android:layout_width="fill_parent"[/COLOR] android:layout_height="fill_parent" />
Which looks like:
Oops, forgot that gravity attribute!
Code:<com.android.systemui.statusbar.policy.Clock android:id="@id/clock" [COLOR="Red"] android:gravity="center"[/COLOR] android:background="#ff33b5e5" android:textColor="#ffffffff" android:layout_width="fill_parent" android:layout_height="fill_parent" />
Here's the result.
Better, no?
So what's the difference between android:gravity and android:layout_gravity?
Well, android:layout_gravity affects how an object is laid out, not in its own space, but in its parent Layout.
Let's try using that to center the clock:
Code:<com.android.systemui.statusbar.policy.Clock android:id="@id/clock" [COLOR="Red"] android:layout_gravity="center"[/COLOR] android:background="#ff33b5e5" android:textColor="#ffffffff" android:layout_width="wrap_content" android:layout_height="fill_parent" />
Here's the result:
So why didn't that work? Well, it really depends on that parent Layout.
In a LinearLayout, some of the layout_gravity attributes are ignored. This would have worked in a RelativeLayout but, as we saw in the Simple Method two posts ago, other objects can overlap the clock.
Generally when you're modding, you normally only worry about layout_gravity when using a RelativeLayout or FrameLayout.
For your reference, here's are the values you can set your gravity to. This is taken direct from Google themselves.
Google said:
Most of those you'll rarely, if ever, use while modding. But it's handy to know about them!
*** WEIGHT ***
Weight is a trickier concept to understand.
Google, on their developer website, have this to say about the layout_weight attribute:
Google said:
In my opinion, this isn't the best explanation ever. It makes things too confusing. (Although it does say a lot about work practices inside Google HQ...clearly I have the wrong job!)
Let me see if I can't explain it a little bit better..
Here's our blank status bar again.
Let's say we want a notification icon and a signal icon here.
Code:<LinearLayout android:orientation="horizontal" android:id="status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.android.systemui.statusbar.phone.IconMerger android:id="@id/notificationIcons" android:background="#ff0099cc" android:layout_width="wrap_content" android:layout_height="fill_parent" /> <ImageView android:id="@id/mobile_signal" android:background="#ff33b5e5" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>
As before, I've missed out a few attributes that you'd have in the real code, just to make things a bit simpler to read.
And, as before, I've added a background to the signal icon. This time I'm using Holo Blue Dark (I like Holo Blue...).
This makes our status bar look like this:
I'm sure you've noticed on your status bar that the notification icons are on the left and the signal icon on the right. That's easy enough to do with a RelativeLayout or a FrameLayout but, if we have too many notifications, we would be overlapping the signal icon.
So, to do this in a LinearLayout, we use layout_weight.
This attribute essentially sets the priority for the object it's attached to.
By default, an object has a layout_weight of 0 (even if there's no layout_weight attribute in the code). So, if we give an object a layout_weight of 1, Android will allocate it more space.
Let's see it in action by changing the layout_weight of our notification icons to 1:
Code:<LinearLayout android:orientation="horizontal" android:id="status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.android.systemui.statusbar.phone.IconMerger android:id="@id/notificationIcons" [COLOR="Red"] android:layout_weight="1"[/COLOR] android:background="#ff0099cc" android:layout_width="0.0dip" android:layout_height="fill_parent" /> <ImageView android:id="@id/mobile_signal" android:background="#ff33b5e5" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>
Android now gives that object as much space in the Layout as it can, effectively pushing the signal icon to the far right.
Because the width of the notification icon object is being changed by the layout_weight, the layout_width attribute is superseded. So you should always set it to "0.0dip", this stops Android from having to waste processing power that's not needed.
Since this is only the status bar, we're not talking about a lot of power and it's doubtful you'd notice any difference in performance. But it's always good practice.
This is essentially how the standard Android status bar is set up.
Yes, there are more icons and more Layout but, at its heart, there is still a notification area with a weight of 1 pushing a status icon area with a weight of 0 to the right of the screen.
Have a look at your status_bar.xml and you'll see what I mean!
For fun, let's see what happens if we change the weight of the signal icon as well...
Code:<LinearLayout android:orientation="horizontal" android:id="status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.android.systemui.statusbar.phone.IconMerger android:id="@id/notificationIcons" [COLOR="Red"] android:layout_weight="1"[/COLOR] android:background="#ff0099cc" [COLOR="Red"] android:layout_width="0.0dip"[/COLOR] android:layout_height="fill_parent" /> <ImageView android:id="@id/mobile_signal" [COLOR="Red"] android:layout_weight="1"[/COLOR] android:background="#ff33b5e5" [COLOR="Red"] android:layout_width="0.0dip"[/COLOR] android:layout_height="wrap_content" /> </LinearLayout>
This results in:
That looks a bit stupid. But not to worry, we can use a spacer to push that signal icon back to the right of the screen again.
Code:<LinearLayout android:orientation="horizontal" android:id="status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.android.systemui.statusbar.phone.IconMerger android:id="@id/notificationIcons" android:layout_weight="1" android:background="#ff0099cc" android:layout_width="0.0dip" android:layout_height="fill_parent" /> <LinearLayout android:orientation="horizontal" android:layout_weight="1" android:layout_width="0.0dip" android:background="#ff33b5e5" android:layout_height="fill_parent" > [color="red"]<View android:visibility="invisible" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1" />[/color] <ImageView android:id="@id/mobile_signal" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> </LinearLayout>
Here we go..
I've changed the signal icon's weight back to 0 and put it inside a LinearLayout with a View object that has a weight of 1.
The View line pushes the signal icon to the far right but has this attribute: "android:visibility="invisible"". Remember this attribute from a few posts ago? If this is set to !invisible, Android doesn't show it but still pays attention to how much space it uses. Making it the perfect spacer!
Why am I doing this? Well, look what happens if we add a clock to all this code (using a background of Holo Blue Bright this time)...
Code:<LinearLayout android:orientation="horizontal" android:id="status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.android.systemui.statusbar.phone.IconMerger android:id="@id/notificationIcons" android:layout_weight="1" android:background="#ff0099cc" android:layout_width="0.0dip" android:layout_height="fill_parent" /> [COLOR="Red"] <com.android.systemui.statusbar.policy.Clock android:id="@id/clock" android:layout_gravity="center" android:background="#00ddff" android:textColor="#ffffffff" android:layout_width="wrap_content" android:layout_height="fill_parent" />[/COLOR] <LinearLayout android:orientation="horizontal" android:layout_weight="1" android:layout_width="0.0dip" android:background="#ff33b5e5" android:layout_height="fill_parent" > <View android:visibility="invisible" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1" /> <ImageView android:id="@id/mobile_signal" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> </LinearLayout>
Here it is:
Well, would you look at that? We've just centered the clock! Neat!
Let's remove those background attributes..
Code:<LinearLayout android:orientation="horizontal" android:id="status_bar_contents" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.android.systemui.statusbar.phone.IconMerger android:id="@id/notificationIcons" android:layout_weight="1" android:layout_width="0.0dip" android:layout_height="fill_parent" /> <com.android.systemui.statusbar.policy.Clock android:id="@id/clock" android:layout_gravity="center" android:textColor="#ffffffff" android:layout_width="wrap_content" android:layout_height="fill_parent" /> <LinearLayout android:orientation="horizontal" android:layout_weight="1" android:layout_width="0.0dip" android:layout_height="fill_parent" > <View android:visibility="invisible" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1" /> <ImageView android:id="@id/mobile_signal" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> </LinearLayout>
Et voilà...
Have another look at the previous two posts. Hopefully they should make a bit more sense now...25*** How To Put An Invisible Softkey In The Status Bar ***
Softkeys are the buttons that are found in the navigation bar at the bottom of the screen. They are normally buttons for BACK, HOME, RECENT APPS and MENU. Although it's not unusual to find some roms with a SEARCH softkey or even some volume controls.
The status bar is the bit at the top of the screen that shows the clock, battery level, signal strength, etc.
Because phones and tablets are getting bigger and bigger, it'd be quite handy to put at least one softkey in it so we don't have to haul our finger all the way to the other end of the screen (trust me, every second counts!).
How hard is it to use something that's in one XML file (navigation_bar.xml) inside a different XML file (status_bar.xml)?
Actually, it's not hard at all!
As with a lot of things to do with the system user interface, we need to decompile our SystemUI.apk. Here's what the stock KitKat navigation_bar.xml looks like:

This is relatively dense code and it can be hard to work out just what it's doing but it does all make sense. For now though, all we need is just one line. Let's say we want to put a HOME softkey in our statusbar. In that case, we just want a line with 'home' in it.
And here it is:
Code:<com.android.systemui.statusbar.policy.KeyButtonView [color="red"]android:id="@+id/home"[/color] android:layout_width="@dimen/navigation_key_width" android:layout_height="match_parent" android:src="@drawable/ic_sysbar_home" systemui:keyCode="3" systemui:keyRepeat="false" android:layout_weight="0" systemui:glowBackground="@drawable/ic_sysbar_highlight" android:contentDescription="@string/accessibility_home" />
We're going to put that into our status bar, so let's have a look at our status_bar.xml:

Being right-handed, I might as well put my HOME softkey to the right of the clock. That way, it's as close to the right side of the status bar as possible. All I need to do is just copy and paste..

And, once I've saved, recompiled and flashed back to the phone, here's the result:
*** But That's Not Invisible, Ticklefish!! ***
You're right, it's not. Not only is the softkey taking up space on my status bar because it's visible, but it also looks a little squashed.
We can change the icon to make it look a bit better...but we're better off doing something a little cleverer..
For this, we're going to use a RelativeLayout to put the clock and the softkey on top of each other. And we need to make a few changes to the attributes of those lines:
Code:<RelativeLayout android:layout_width="wrap_content" android:layout_height="fill_parent"> <com.android.systemui.statusbar.policy.Clock android:layout_alignParentRight="true" android:id="@+id/clock" android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:layout_width="wrap_content" android:layout_height="match_parent" android:singleLine="true" android:paddingStart="6dip" android:gravity="center_vertical|start" /> <com.android.systemui.statusbar.policy.KeyButtonView android:layout_alignParentRight="true" android:id="@+id/home" android:layout_width="20.0dip" android:layout_height="match_parent" systemui:keyCode="3" systemui:keyRepeat="false" android:layout_weight="0" systemui:glowBackground="@drawable/ic_sysbar_highlight" android:contentDescription="@string/accessibility_home" /> </RelativeLayout>
Here's the code in full:

I've removed the reference to the image file in the softkey line and changed the width to 20 density-independent pixels. That width may need changing, depending on your personal preference. Too big and there'll be a big gap between the clock and the battery icon. Too small and the softkey will be very hard to tap. Experiment to find the value that works for you.
By using the RelativeLayout and the 'android:layout_alignParentRight' attribute, I've ensured that the clock and the softkey occupy the same part of the status bar. Because the softkey now has no image file, it's basically invisible.
Just tap on the clock to go back to the home screen!
(You could use a FrameLayout instead of a RelativeLayout, which would be simpler. But it's worth getting used to how RelativeLayouts work, they can be very useful!)
Of course, you don't have to put the HOME softkey in your status bar. It could be the MENU softkey, the RECENT APPS softkey, even a POWER or SEARCH softkey if you know how.
Or you can have more than one in there. Or they can be visible.
It's your device, you can do what you want.
Just make sure to make a backup before you start modding though!
