title: Why am I able to click "behind" the bottomsheet in Android?
body: <p>I have a <code>BottomSheet</code> in my Activity. </p>
  
  <p>I'm calling <code>behavior.setState(BottomSheetBehavior.STATE_EXPANDED);</code> to show the bottom sheet and it works fine, but the problem I have is that I can somehow click on the empty space of my bottom sheet to trigger <code>onClick</code> event of a view that is behind the bottom sheet.</p>
  
  <p>Is there a way to prevent this from happening?  </p>
