title: Android inverse shape using xml
body: <p>Is it possible to 'invert' an Android xml shape? For example, you can easily create a shape with rounded corners - but what about a shape with a transparent element within it?</p>

  <p>Is it possible to add a view that contains a transparent element in front of this (shown in green below)?</p>
