How can I add a shadow/fade for my views?

The ListView has a nice fade on the top/bottom.

I have a ListView in the top开发者_StackOverflow half of my app, and then a ViewFlipper on the bottom. Is it possible to add a fade/shadow to the top of the ViewFlipper? This would look nice.

You can lay a View on top of the ViewFlipper or you can change the background of the ViewFlipper and adjust the top padding.
