How to move a button (or any widget) on touch in your Android App’s layout? – can be used while designing a game

In this video it shows how to implement or develop your Android App in which the buttons or any other widget moves on touching it.

It uses onTouchListener on the widget to move it and then sets it position using setTop, setBottom, setLeft and setRight APIs.

This concept can be used while designing some simple game in your Android App layout.
