Android-maps-utils: New ClusterItems not drawn, unless the map is zoomed

[dadino]

This is what happens:

1. Map is loaded.
2. First batch of ClusterItems is added.
3. mClusterManager.cluster()
4. First batch of ClusterItems is drawn on map.
5. Second batch of ClusterItems is added.
6. mClusterManager.cluster()
7. Second batch of ClusterItems is NOT drawn on map.
8. Map is zoomed (in or out).
9. Second batch of ClusterItems is drawn on map.

Is there a workaround to this?

I'm having the same issue when updating markers. I'm trying to update marker icons by clearing them and re-adding them but this issue occurs after doing so. This occurs even when clearing the map and item list before adding more items.

same issue here.

I experience the same problem. The only solution I have to solve this is reset your marker renderer every time you (re)add items. In my scenario:

clusterManager.clearItems();
clusterManager.addItems(cars);
clusterManager.cluster();
clusterManager.setRenderer(new DefaultClusterRenderer<Car>(this, map, clusterManager) {

    @Override
    protected void onBeforeClusterRendered(Cluster<Car> cluster, MarkerOptions markerOptions) {
        ClusterHelper.initCluster(cluster, markerOptions);
    }

    @Override
    protected void onBeforeClusterItemRendered(Car car, MarkerOptions markerOptions) {
        ClusterHelper.initClusterItem(car, markerOptions);
    }
});

Try this method:
mClusterManager.cluster();
worked for me 👍
