Items not "declustered" (broken into smaller items) after map zooms in

[vanjabobotic]

Summary:

When you zoom in, some items stays in cluster, no matter how close you zoom in.

Steps to reproduce:

Unfortunately, I'm not sure. It happens all the time, but only for some locations.

Expected behavior:

I'm expecting to see the "broken" clusters when the map is zoomed in.

Observed behavior:

Instead, the items are clustered all the time, whether you click on the cluster on zoom in.

Device and Android version:

It happens on any Android device with any Android I've tried (>5.0), the stock version ROM from the manufacturer.

Got the same problem with web page. Some clusters work correctly, but some don't and don't break down when zooming.

did you try changing the code below?

@Override protected boolean shouldRenderAsCluster(Cluster cluster) { return cluster.getSize() > 2; }

if the pins are so close, it's natural that they will keep as a cluster since would be a mess to understand them

I can say that in my case pins are not close at all, in fact there are no any pin closer than few tens kilometers around the marker on my screenshot. My pins are real house addresses.

Has this problem been solved in some way?

When pins are so close and the map zoomed in high level, pins don't uncluster.how to fix this problem?

Hi guys!
I had solved this problem in two ways:
First One just set setMinClusterSize(1); // however if your lat and long are exactly the same or very close sometimes a cluster will be showed.

Second one:

implements OnCameraMoveListener on your CustomRenderer or implements it in your activity and set the maxZoomLevel in your CustomClusterRenderer doing it you avoid to keep a referecen for the Map.
Create a float variable to save the max zoom level which google maps can work with in this case the constructor do the job.

public class CustomClusterRenderer extends DefaultClusterRenderer<MapMarker> implements GoogleMap.OnCameraMoveListener { 

    private final float maxZoomLevel;
    private final float zoomOffset = 5f;

    public CustomClusterRenderer(Context context, GoogleMap map, ClusterManager<MapMarker> clusterManager) {
        super(context, map, clusterManager);
        this.mMap = map; // you don't need to keep this reference if you dont need
        this.maxZoomLevel = mMap.getMaxZoomLevel() - zoomOffset;
      }
}

I just get the current zoom level.

 @Override
    public void onCameraMove() {
        currentZoom = mMap.getCameraPosition().zoom;
    }

Finally the method shouldRenderAsCluster

@Override
    protected boolean shouldRenderAsCluster(Cluster<MapMarker> cluster) {
        boolean wouldCluster = super.shouldRenderAsCluster(cluster);

        //determine if you still want it based on ZoomLevel
        if (wouldCluster) {
            wouldCluster = currentZoom < maxZoomLevel;
        }

        return wouldCluster;
    }

Looks like @gusthavosouza solved this in his comment above - #443 (comment).

If this solution doesn't work for anyone please re-open this issue. Thanks!
