title: How to enable Drag a Marker (Android Map Api v2) after a single Touch?
body: <p>I have a map with some markers. I set the listener for drag: </p>
  
  <pre><code>map.setOnMarkerDragListener(this);
  </code></pre>
  
  <p>But the drag is enable only after the user long press the marker. I want to enable drag immediately. Is there a way to do this with Android Maps (v2)?</p>
