Ive got a checkbox which should set a textview visible while checked, and hide it when its not checked. I have also created two basic animations that should appear during hiding and showing of the textview (fadeIn and fadeOut). Heres my onclicklistener for the checkbox:
And here are my two animations:
My problem is that the fade animation only shows when I uncheck the checkbox (hide the textbox). When I try to check the box (show the textview) it just appears without showing the animation. Any help would be appreciated. Thanks in advance.
Edit: Had to move "textView1.setVisibility(View.VISIBLE);" into the onAnimationStart method.
Code:
checkBox1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
fadeIn = AnimationUtils.loadAnimation(getActivity(), R.anim.fade_in);
fadeOut = AnimationUtils.loadAnimation(getActivity(), R.anim.fade_out);
if (((CheckBox) v).isChecked()) {
fadeIn.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
textView1.setVisibility(View.VISIBLE);
}
});
textView1.startAnimation(fadeIn);
}
else {
fadeOut.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
textView1.setVisibility(View.GONE);
}
});
textView1.startAnimation(fadeOut);
}
}
});
And here are my two animations:
Code:
<!-- fade_in.xml -->
<?xml version="1.0" encoding="UTF-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="300"
android:fillAfter="true"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
Code:
<!-- fade_out.xml -->
<?xml version="1.0" encoding="UTF-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="300"
android:fillAfter="true"
android:fromAlpha="1.0"
android:toAlpha="0.0" />
