Answer 1

you need to get all this gif frame image as individual and then set into the animation-list in xml file.

Here is your anim_progress.xml file code

set the duration for change as smooth effect for giving animated image like gif

Here is the code for using this file

ImageView iv = new ImageView(this);
iv.setBackgroundResource(R.drawable.anim_progress);
final AnimationDrawable mailAnimation = (AnimationDrawable) iv.getBackground();
iv.post(new Runnable() {
    public void run() {
        if ( mailAnimation != null ) mailAnimation.start();
      }
});

setContentView(iv);

you can get all frames from gif file from this site.
