What does an Android StackView look like?

Can someone prov开发者_JAVA百科ide a screenshot of an Android StackView that shows a potential application of this widget? I'm not sure what to use it for.

There is one on this page. Here's the screencap they display:

An item flips off of the front, and onto the back (sort of like a deck of cards).

There's an example here from the Android examples you can implement to see what it does. I suspect a screenshot may not be adequate enough since the widget inherits from AdapterViewAnimator.
