How to set my own icon for markers in clusterer in Google Maps

Question

I'm using GoogleMaps clustering. I have 4 different types of markers, each extends from one abstract class, each has its owm icon and it defined in MarkerOptions field. I use ClusterManager for this abstract class. When I just use

//marker is instance of one of extended classes and has abstract class type
clusterManager.addItem(marker);

After clustering it sets icon to default. How I can fix this? I was trying to use something like this:

//marker is abstract marker, getMarker returns the MarkerOptions of this marker
clusterManager.getMarkerCollection().addMarker(marker.getMarker());

but it doesn't work too, marker is printed with needed icon on map, but without clustering.

Should I create create some method in my abstract class or there are some way to do this extending from DefaultClusterRenderer? I haven't found some information about it using Google or learning google maps lib.

Thanks for helping!

Answer 1

So, it was my foolish. Again, it shows, that I should pay more attention, studying library. If somebody is interested in answer, here it is: I was right supposing, that I need to override some method in DefaultClusterRenderer. So, the full way: Create own class and extend it from DefaultClusterRenderer:

public class OwnIconRendered extends DefaultClusterRenderer<AbstractMarker>

Then override method onBeforeClusterItemRendered:

@Override
protected void onBeforeClusterItemRendered(AbstractMarker item,
        MarkerOptions markerOptions) {
    markerOptions.icon(item.getMarker().getIcon());
}

The way is rather simple, but it seems to me, that clustering started to work slower. So, that's enough.
