Answer 3

Whether you like it or not, any View is drawn on a Canvas , which is uniquely rectangular in shape. Only a custom View is suitable for your task, in the onDraw method of which you draw a round button, and in the onKeyDown method you calculate the coordinates and decide whether the event should be processed or not, initiating an additional performClick to call subscriber handlers.

Answer 4

Show how you set the round background for the button.
