title: Dispatch touch event to a sibling view
body: <p>I have developped a custom layout that extends ViewGroup. Now, I want to use it in an activity. In my activity, I have both this layout and a viewpager inside a framelayout. My custom layout fills my Frame layout and is above my viewPager.</p>
  
  <p>I would like to be able to handle click events on my custom layout and let all the other motions go to the viewpager so it can still scroll.</p>
  
  <p>I haven't managed so far. Either I have the click but the viewpager cannot scroll anymore, or the contrary. I have overriden onTouchEvent and onInterceptTouchEvent.</p>
  
  <p>What I notice is that, I correctly receive the down event on my custom layout, but once it has been catched by the viewpager, I do never get up there. How can I make communications between sibling views for touch events ?</p>
  
  <p>PS : I have tried splitMotionEvent to no avail</p>
