If you has your own custom View who has a RotateDrawable and want to make it rotate, following code may help. The trick is to call Drawable.setLevel() on the drawable.

	private Drawable mLoadingDrawable;

	private Transformation mTransformation;
	private AlphaAnimation mAnimation;
	private boolean mHasAnimation;
	private Interpolator mInterpolator;
	private long mLastDrawTime;

	private static final int ANIMATION_RESOLUTION = 200;
	private static final int MAX_LEVEL = 10000;
