title: share TouchEvent between fragments
body: <p>I have 2 fragments, sharing the screen.
  In both, there is a layout that is listening to TouchEvents.<br>
  When I start a TouchEvent on the first fragment, and then moving my finger on top of the second one, the TouchEvent is still received by the first one, and never by the second.<br>
  I've tried different options without success. Could it be a solution, to handle the TouchEvent from the activity, and then dispatching it to both fragments ?<br>
  Any clue is welcome =)</p>
