I found it. it is named as circular reveal animation. this is the code for implementing it.

Java

private void RippleAnimation()
    {
        // get the top left for the clipping circle
        int cx = 0;
        int cy = 0 ;

        // get the final radius for the clipping circle
        int finalRadius = Math.max(myView.getWidth(), myView.getHeight());

        // create the animator for this view (the start radius is zero)
        Animator anim =
                ViewAnimationUtils.createCircularReveal(myView, cy, cx, 0, finalRadius);

        //Interpolator for giving effect to animation
        anim.setInterpolator(new AccelerateDecelerateInterpolator());
        // Duration of the animation
        anim.setDuration(500);

        // make the view visible and start the animation
        myView.setVisibility(View.VISIBLE);
        anim.start();
    }

happy coding :)
