How to change the screen in android application?

Hi.. I am new to android development.. I was trying to move from one screen to another and I could do it thru intent but I wanted do it with out clicking on button.. Like with the move of your touch.. If you touch the screen and push it right other screen should come up.. and the same when you push it left..

how to implement this? Any suggestion would be highly appreciated. Thanks in advance for help....

Implement Gesture API.

or View Flipper is I think what you are looking for.
