Ability to split clustered marker to list of regular markers. about android-maps-extensions HOT 7 CLOSED

Splitting is possible. Just need to disable clustering when hitting certain 
zoom level (see code below).




private boolean clusteringEnabled;

in onCameraChange:

if (cameraPosition.zoom > 20.7) {
  if (clusteringEnabled) {
    map.setClustering(new ClusteringSettings().enabled(false).addMarkersDynamically(true));
    clusteringEnabled = false;
  }
} else {
  if (!clusteringEnabled) {
    // your normal clustering settings
    clusteringEnabled = true;
  }
}

It wokrs great! Thanks!

Now it is also possible to achieve spliting a single cluster into markers by 
setting different cluster group on each marker (or just -1 in the next release 
after 1.5.1).

This was resolved as part of Issue 10.

To split specific cluster use

Marker cluster = ...
for (Marker marker : cluster.getMarkers()) {
    marker.setClusterGroup(ClusterGroup.NOT_CLUSTERED);
}

Just wanted to point that when using the proposed solution for disabling 
clustering when zooming in to a certain zoom level, you may also want to change 
this in DelegatingOnCameraChangeListener:

From:

@Override
public void onCameraChange(CameraPosition cameraPosition) {
   markerManager.onCameraChange(cameraPosition);
   if (onCameraChangeListener != null) {
      onCameraChangeListener.onCameraChange(cameraPosition);
   }
}

To:

@Override
public void onCameraChange(CameraPosition cameraPosition) {
   if (onCameraChangeListener != null) {
      onCameraChangeListener.onCameraChange(cameraPosition);
   }
   markerManager.onCameraChange(cameraPosition);
}

Otherwise, if you zoom out the map very quickly to a very little zoom level 
after being in a non-clustered zoom level, first all the markers are drawn to 
the map, becoming unresponsive for a while, and later clustering is reapplied.

@#6 eereza

That's a good idea for a custom modification in your code when implementing my 
suggestion from comment #2, but I can't do that in the code, because it would 
be inconsistent, e.g. when trying to use GoogleMap.getDisplayedMarkers in 
onCameraChange, you would get a list of markers before clustering is applied.

If I were to use my #2 suggestion, I would probably add 
BeforeCameraChangeListener and make the code look like:

@Override
public void onCameraChange(CameraPosition cameraPosition) {
   if (beforeCameraChangeListener != null) {
      beforeCameraChangeListener.beforeCameraChange(cameraPosition);
   }
   markerManager.onCameraChange(cameraPosition);
   if (onCameraChangeListener != null) {
      onCameraChangeListener.onCameraChange(cameraPosition);
   }
}

and put code from #2 into beforeCameraChange... or just hardcode it before 
markerManager is called.
