title: How can I requestDisallowTouchEvents on Android DrawerLayout
body: <p>I have an instance where I need a <code>GestureDetector</code> in my <code>Activity</code> to intercept horizontal flings.  This activity also happens to contain a <code>DrawerLayout</code>.  </p>
  
  <p>The problem I'm having is that the <code>DrawerLayout</code> intercepts all touch events such that I can't even <code>requestDisallowInterceptTouchEvents</code>.  I can't seem to ever get a touch even in the Activity to trigger that call.</p>
  
  <p>I'd like the Drawer to handle swipes from the edge when closed, and from anywhere when opened, like it's supposed to. ButI need my activity to be able to intercept touch events elsewhere when the drawer is closed.</p>
