Help with Gallery App

heahmad · May 16, 2014

I have found a gallery app that I have integrated into my own app.
http://manishkpr.webheavens.com/android-viewpager-as-image-slide-gallery-swipe-gallery/
Currently the gallery displays images that are founded in drawable i want to modify it to show image from sd card (i.e. /sd/images/)
I tried different approach but without luck, unfortunately.

Thanks in advance!

You have to use BitmapFactory.decodeFile() on each File in that directory. You can then set the returned bitmap to your imageView in the instantiateItem() method of your PagerAdapter with setImageBitmap(). Though you might want to cache thing first for better performance...

ok i know that, but the problem is that the app itself generate photos with different number and name (Timestamp) so i want it to read an entire folder not a single file each time

you can get all images from diretory

PHP:

File file= new File(android.os.Environment.getExternalStorageDirectory(),"MyFolder");

        if (file.isDirectory())
        {
            listFile = file.listFiles();


            for (int i = 0; i < listFile.length; i++)
            {

                f.add(listFile[i].getAbsolutePath());

            }
        }
