title: Android View Clipping
body: <p>Is there any way to define the clip region of a ViewGroup in android (Honeycomb)? For example, I have a ListView with an image background that has rounded corners. As I scroll through the list, the children stick out past the corners of the background - I would prefer them to clip within the rounded corners.
  <img src="https://i.stack.imgur.com/2kmt6.png" alt="Left: unclipped, Right: clipped"></p>
  
  <p>The left image is what it is currently doing, and the right is what I'd like.</p>
  
  <p>I was looking at ClipDrawable, but it seems that this may only be used for progress bars?</p>
  
  <p>Also, I'm trying to do this in a widget. So I cannot use a custom view and override onDraw for masking.</p>
  
  <p>Thank you!</p>
