How to manage click on marker which is not in Clus

I am having trouble implementing OnClickListener for Marker(s) which are not in Cluster, i.e. not added using:

 mClusterManager.addItem(markerCluster);

I have set OnMarkerClickLister as follows:

 mMap.setOnCameraIdleListener(mClusterManager);
 mMap.setOnMarkerClickListener(mClusterManager);

If I just use:

 mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
        @Override
        public boolean onMarkerClick(Marker marker) {
            return false;
        }
    });

the click on markers is not working at all.

For example: I have this situation:

Two green dots and big blue dot (with number 6) are one Cluster, but the red marker is not in Cluster as I don't want it to be Clustered like other markers. InfoWindow is normally showing when I click on red marker, but onMarkerClick doesn't work - as well as OnClusterItemClickListener. But OnClusterItemClickListener works when I click on markers which are in Cluster.

Hope you understand what I am trying to achieve. If not, please let me know.

The image that you added in your edit explains the issue clearly, thanks for that!

In order too solve this issue we need to register the listener differently. Namely: by registering it to the ClusterManager's MarkerManager as that class handles everything of the markers now. We also need to add the NormalMarkers a bit differently, so lets go through it step by step:

1) Update the OnMarkerClickListener of the mMap:

mMap.setOnMarkerClickListener(mClusterManager.getMarkerManager()); // Note the `MarkerManager` here

2) This MarkerManager holds all the collections. We need to create a new collection on this manager to which we will add the NormalMarkers that should be displayed apart from the clusters:

MarkerManager.Collection normalMarkersCollection = mClusterManager.getMarkerManager().newCollection();

3) Adding the markers is done similar to how this was before, but with using the addMarker() method on the collection that we created. We must pass a MarkerOptions() object to this:

// Create a normal marker
val markerOptions = MarkerOptions()
    .position(new LatLng(...))
    .title("My marker")
    .snippet("With description")

// Add it to the collection
normalMarkersCollection.addMarker(markerOptions)

4) Last but not least: we want the OnClickListener on it:

normalMarkersCollection.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener {
    public boolean onMarkerClick(marker: Marker) {
        // NORMAL MARKER CLICKED!
        return false;
    }
})

5) Done! Now the normal markers are added to the map just like before, but with a working OnMarkerClickListener.

Earlier answer

(Setting the click listeners for the clusters and clustered items)

You should add the clicklistener to the mClusterManager. Setting the clicklistener on the mMap does not work when using the ClusterManager.

Thus instead of using mMap.setOnMarkerClickListener, set the ClusterItemClickListener on the cluster manager:

mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<MyItem>() {
    @Override
    public boolean onClusterItemClick(MyItem item) {
        Log.d("cluster item","clicked");
        return true;
    }
});

Additionally, if you want to capture the onclick of the clustered item item, use the ClusterClickListener:

mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<MyItem>() {
    @Override
    public boolean onClusterClick(Cluster<MyItem> cluster) {
        Log.d("cluster","clicked");
        return true;
    }
});

If you want to have both Marker and Cluster listeners working you can write

mGoogleMap.getMarkerManager().onMarkerClick(marker);

inside your OnMarkerClickListener
