I think the most elegant and versatile option is to extend from the ImageView class:

        init();
    }

    private void init() {
        setBackgroundResource(R.drawable.loader);
        final AnimationDrawable frameAnimation = (AnimationDrawable) getBackground();
        post(new Runnable(){
            public void run(){
                 frameAnimation.start();
             }
        });
