I am not familiar with those views, but the way to create circular reveal is as follows:

val view= ... //Get your view
val cx = view.width / 2
val cy = view.height / 2
val finalRadius = Math.hypot(cx, cy)
val anim = ViewAnimationUtils.createCircularReveal(view, cx, cy, 0, finalRadius) //this is the important one here
anim.start()
