title: DrawerLayout: Disable clicks on content when drawer is open
body: <p>I have a DrawerLayout which contains a ListView and a FrameLayout, which contains a TabHost. If I click in a empty area of my DrawerLayout, the click gets passed down to the FrameLayout, often changing the state of my tabs. The tabs are hidden from view, so I don't want this to happen.</p>
  
  <p>Is there any method to intercept touch events when the DrawerLayout is open so this does not happen?</p>
