Issue on removing item from clustermanager

Question

In my Android application, I have to delete and re-add a cluster item in my GoogleMap, that represents my current location. But when I run this code:

cluster         


        

Answer 1

By default ClusterManager uses NonHierarchicalDistanceBasedAlgorithm, that doesn't implement removing elements.

Try to use GridBasedAlgorithm instead (it supports elements remove):

clusterMng.setAlgorithm(new GridBasedAlgorithm());

Or, for better performance, wrap it with PreCachingAlgorithmDecorator, as ClusterManager does by default:

clusterMng.setAlgorithm(new PreCachingAlgorithmDecorator(new GridBasedAlgorithm()));
