abstract fun onDraw(): Unit
Callback method to be invoked when the view tree is about to be drawn. At this point, views cannot be modified in any way.
Unlike with OnPreDrawListener, this method cannot be used to cancel the current drawing pass.
An OnDrawListener listener cannot be added or removed from this method.
