I have three view on the same place. I need to show them like they are in a serial page.

When btn1 pressed view1 need to show. When I change view to view3 the view 1 & 2 two should slide to left so that user thinks these views are serial, as in the pic.
You have to use ViewFlipper and animation for your requirement. Below link provides how to use ViewFlipper and animation. Understand the code in this example and modify this to your actual layouts and requirements.
Android transitions- slide in and slide out
You can use ViewPager also, but it is some what typical than ViewFlipper.
