final View oval = this.findViewById(R.id.oval);

@Override
public void onClick(View v) {
Animator animator = ViewAnimationUtils.createCircularReveal(

oval.getWidth()/2,
oval.getHeight()/2,
oval.getWidth(),
0);
animator.setInterpolator(new AccelerateDecelerateInterpolator());

}
});
final View rect = this.findViewById(R.id.rect);
rect.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Animator animator = ViewAnimationUtils.createCircularReveal(rect, 0, 0, 0, (float) Math.hypot(rect.getWidth(), rect.getHeight()));
animator.setInterpolator(new AccelerateInterpolator());
animator.setDuration(2000);
animator.start();
}
