How to add title, snippet and icon to ClusterItem?

Question

I had this activity:

public class MapViewer extends Activity {

    private GoogleMap map;
    private Database db = new Database(this);

    protected void

Here you should work with ClusterManager itself. For example, setting on cluster item click:

        mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<MyItem>() {
            @Override
            public boolean onClusterItemClick(MyItem item) {
                //put your code here
                return false;
            }
        });

And there are other different methods in ClusterManager class. You'll need a less obvious code to assign info window to marker or cluster - you should use this code:

mClusterManager.getMarkerCollection().setOnInfoWindowAdapter(new MarkerInfoWindowAdapter());
mClusterManager.getClusterMarkerCollection().setOnInfoWindowAdapter(new ClusterInfoWindow());

There MarkerInfoWindowAdapter and ClusterWindowAdapter is your classes, which implements GoogleMap.InfoWindowAdapter.

With icons it's a little harder, because clustering changes icons to default. You should use method:

public void setRenderer(com.google.maps.android.clustering.view.ClusterRenderer<T> view)

You could your own renderer class and override some methods. For example, to set custom icons use such a class:

class OwnIconRendered extends DefaultClusterRenderer<MyItem> {

    public OwnIconRendered(Context context, GoogleMap map,
                           ClusterManager<MyItem> clusterManager) {
        super(context, map, clusterManager);
    }

    @Override
    protected void onBeforeClusterItemRendered(MyItem item, MarkerOptions markerOptions) {
        markerOptions.icon(item.getIcon());
        markerOptions.snippet(item.getSnippet());
        markerOptions.title(item.getTitle());
        super.onBeforeClusterItemRendered(item, markerOptions);
    }
}

And use it in such way:

mClusterManager.setRenderer(new OwnIconRendered(activity.getApplicationContext(), getMap(), mClusterManager));
