How to animate .gif images in an android?

Question

Here is the code for xml:

Answer 1

It's not good practice to use Threads (i.e. View.post(new Runnable)) because the view might have changed during the time the drawable is going to be painted (one case is using the animated image on ListView with items containing different background images), which may cause a ClassCastException if the ImageView, by the time the thread runs, has a background that is not an animated resource.

ImageView loadingImg = (ImageView)v.findViewById(R.id.image);
loadingImg.setBackgroundResource(R.drawable.progressdialog);
loadingImg.addOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {
  @Override
  public void onViewAttachedToWindow(View v) {
    AnimationDrawable loadingAnimation = (AnimationDrawable) v.getBackground();
    loadingAnimation.start();
  }

  @Override
  public void onViewDetachedFromWindow(View v) {
  }
});
