title: onClusterItemInfoWindowClick is not getting called for Google maps in Android
body: <p>EDIT: This question is in reference to Google Maps on Android.</p>
  
  <p>I am trying to make custom info window for markers with clustering. I followed the instructions given here <a href="https://stackoverflow.com/a/21964693/1641882">https://stackoverflow.com/a/21964693/1641882</a></p>
  
  <p>I did these :</p>
  
  <p>Setup the cluster manager to act as info window adapter</p>
  
  <pre><code>// Setting custom cluster marker manager for info window adapter
      map.setInfoWindowAdapter(mClusterManager.getMarkerManager());
      mClusterManager.getMarkerCollection().setOnInfoWindowAdapter(new MyLocationInfoWindowAdapter());
  </code></pre>
  
  <p>Set a click listener for clusterItem info window</p>
  
  <pre><code>mClusterManager.setOnClusterItemInfoWindowClickListener(new ClusterManager.OnClusterItemInfoWindowClickListener&lt;LocationMarker&gt;() {
          @Override
          public void onClusterItemInfoWindowClick(LocationMarker locationMarker) {
              Toast.makeText(context, "info window Click", Toast.LENGTH_SHORT).show();
          }
      });
  </code></pre>
  
  <p>Here is my Info Window Adapter</p>
  
  <pre><code>private class MyLocationInfoWindowAdapter implements GoogleMap.InfoWindowAdapter {
      @Override
      public View getInfoWindow(Marker marker) {
          return null;
      }
  
      @Override
      public View getInfoContents(Marker marker) {
          TextView helloTextView = new TextView(getContext());
          helloTextView.setText("Hello Info contents");
          helloTextView.setClickable(false);
          return helloTextView;
      }
  }
  </code></pre>
