/**
 * Returns an Animator which can animate a clipping circle.
 * <p>/*from  w ww.ja  v a  2  s  .co  m*/
 * Any shadow cast by the View will respect the circular clip from this animator.
 * <p>
 * Only a single non-rectangular clip can be applied on a View at any time.
 * Views clipped by a circular reveal animation take priority over
 * {@link android.view.View#setClipToOutline(boolean) View Outline clipping}.
 * <p>
 * Note that the animation returned here is a one-shot animation. It cannot
 * be re-used, and once started it cannot be paused or resumed.
 *
 * @param view The View will be clipped to the animating circle.
 * @param centerX The x coordinate of the center of the animating circle.
 * @param centerY The y coordinate of the center of the animating circle.
 * @param startRadius The starting radius of the animating circle.
 * @param endRadius The ending radius of the animating circle.
