title: How to extend a view's touch area
body: <p>I have a vertical <code>LinearLayout</code>. It shall act as a quick jump bar. So the width is very small and the height matches nearly the whole screen height. When I touch it and move around inside, everything is fine. That means, my <code>onTouchEvent()</code> is called and I can get (and follow) the position of the finger. But since the bar is not very wide, the user can easily drift outside of that view. So it would be necessary to let the user continue the movement even when outside the view. In fact the same thing like a <code>ListView</code> does.</p>
  
  <p>I don't know why a <code>ListView</code>'s <strong><code>onTouchEvent()</code></strong> is called even when outside the <code>ListView</code>, but not in case of my <code>LinearLayout</code>. I tracked it down back to the <strong><code>dispatchTouchEvent()</code></strong>. Here the situation is the same that method is always called for the <code>ListView</code> (even when outside) but not in case of the <code>LinearLayout</code> (when moving outside).</p>
  
  <p>I'd be very happy if someone could give me a hint. Thanks a lot!</p>
