title: Android - Get Click Event of Map Overlay Item
body: <p>I have a MapView with Overlays like this:</p>
  
  <pre><code>public class MyMapActivity extends MapActivity
  {
      private MapItemizedOverlay itemizedOverlay;
  
      @Override
      public void onCreate(Bundle savedInstanceState)
      {
      for(a loop to put all 10 datas into overlay)
      {
      OverlayItem overlayitem=new OverlayItem(some params);
      overlayitem.setMarker(some bitmap);
      itemizedOverlay.addOverlay(overlayitem);
  }
  mapView.getOverlays().add(itemizedOverlay);
  }
  }
  
  public class MapItemizedOverlay extends ItemizedOverlay&lt;OverlayItem&gt;
  {
  
    //some code
  
  @Override
  protected boolean onTap(int index)
  {
  //Here I know what marker been clicked...
  }
  }
  </code></pre>
