title: android: move a view on touch move (ACTION_MOVE)
body: <p>I'd like to do a simple control: a container with a view inside. If I touch the container and I move the finger, I want to move the view to follow my finger. </p>
  
  <p>What kind of container (layout) should I use? How to do this?</p>
  
  <p>I don't need to use a surface, but a simple layout.</p>
