In Android, when swipe to change the screen how to show an animation with both screen

Question

Sorry the title isn't clear enough. I don't know how to express it, but the image here says it all.

In the Google Reader App, if the uses swipe left or right on the current post, they will see the first post moves out as the second one moves in. It's a nice effect, but I have no clue how to implement it.

Any ideas?

You need to use a ViewPager with fragments:
