title: ScrollView: Pass touch events to children
body: <p>I made a "joystick" out of an <code>ImageView</code>. It is inside a <code>ScrollView</code>.</p>
  
  <p>It works without the <code>ScrollView</code> but inside the <code>ScrollView</code> it does not receive <code>TouchEvents</code> for vertical movement.</p>
  
  <p>How can I stop the <code>ScrollView</code> from blocking the touch event?</p>
