I haven't worked with a RotateDrawable, but if you're simply trying to animate rotation on a graphic, you don't need it. Drawables with a 'level' like RotateDrawable are meant to convey information rather than animate views.

The following code rotates an ImageView around its center:

ImageView myImageView = (ImageView)findViewById(R.id.my_imageview);

AnimationSet animSet = new AnimationSet(true);
animSet.setInterpolator(new DecelerateInterpolator());
animSet.setFillAfter(true);
animSet.setFillEnabled(true);

final RotateAnimation animRotate = new RotateAnimation(0.0f, -90.0f,
    RotateAnimation.RELATIVE_TO_SELF, 0.5f, 
    RotateAnimation.RELATIVE_TO_SELF, 0.5f);

animRotate.setDuration(1500);
animRotate.setFillAfter(true);
animSet.addAnimation(animRotate);

myImageView.startAnimation(animSet);
