Sample demonstrating circular reveal effect. Reveal animations can be used to provide visual continuity when showing or hiding views. With ViewAnimationsUtils.createCircularReveal() you can use the startRadius and endRadius to define a hiding or revealing animation. You can also define the center of the animation, in this sample the center is x=0, y=0 which defines the top left of the View as the center.
