Is this what you mean? If yes then here is the main idea:

Lets talk about the coordinates (x = Horizontal, y = Vertical)

The main idea of the program is, when the coordinate reach the end of your screen (For example your Horizontal phone size is 100), so when the X coordinate reach 100 (from 0), the ball should be bounced back so that coordinate will be decreased until it reach 0 again.

The same with the Y coordinate.
