title: Android Maps Utils Clustering show InfoWindow
body: <p>I am planning to use the google maps marker clustering available in the utils library, but the google example app only shows marker clusters without any infoWindow. I am wondering now, am I not able to show a InfoWindow? I want the InfoWindow to be displayed on the marker like with a normal google maps marker, not on the cluster.</p>
  
  <p>The code I have: (From the google example)</p>
  
  <pre><code>public class BigClusteringDemoActivity extends FragmentActivity {
      private ClusterManager&lt;MyItem&gt; mClusterManager;
      private GoogleMap mMap;
  
      private void readItems() {
          InputStream inputStream = getResources().openRawResource(R.raw.radar_search);
          List&lt;MyItem&gt; items = new MyItemReader().read(inputStream);
  
          for (int i = 0; i &lt; 10; i++) {
              double offset = i / 60d;
              for (MyItem item : items) {
                  LatLng position = item.getPosition();
                  double lat = position.latitude + offset;
                  double lng = position.longitude + offset;
                  MyItem offsetItem = new MyItem(lat, lng);
                  mClusterManager.addItem(offsetItem);
              }
          }
      }
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.map);
  
          mClusterManager = new ClusterManager&lt;&gt;(this, mMap);
  
          mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
  
          mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(51.503186, -0.126446), 10));
          mMap.setOnCameraChangeListener(mClusterManager);
  
          readItems();
      }
  
  }
