Question

我按照教程cluster google map添加我的项目，然后运行。但是现在我在地图中有两个类型项，所以我想为每个类型项创建两个集群管理器。我搜索并查看multiple cluster manager，但是当我无法在setOnCameraChangeListener（）方法中添加onCameraChange时。如何在地图中添加多个群集？非常感谢你！

使用MarkerManager

 @Override
public void onMapReady(GoogleMap googleMap) {
    isMapReady = true;
    map = googleMap;
    map.getUiSettings().setZoomControlsEnabled(false);
    map.getUiSettings().setMyLocationButtonEnabled(false);
    map.getUiSettings().setCompassEnabled(false);
    Gps lastGps = ((PagerActivity) getActivity()).getLastGPS();

    MarkerOptions markerOptions = new MarkerOptions()
            .position(new LatLng(lastGps.getLat(), lastGps.getLng()))
            .icon(BitmapDescriptorFactory.fromResource(R.drawable.radar_boy));
    map.addMarker(markerOptions);
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(lastGps.getLat(), lastGps.getLng()), 12));

    MarkerManager markerManager = new MarkerManager(map);

    clusterManager = new ClusterManager<MarkerItem>(getContext(), map, 
  markerManager);
        clusterManager1 = new ClusterManager<MarkerItem>(getContext(), map, markerManager);

    map.setOnMarkerClickListener(markerManager);
    map.setOnInfoWindowClickListener(markerManager);

        map.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() {
            @Override
            public void onCameraChange(CameraPosition cameraPosition) {
                clusterManager.onCameraIdle();
                clusterManager1.onCameraIdle();
            }
        });

        ClusterRenderer clusterRenderer = new ClusterRenderer(getContext(), map, clusterManager);
        clusterManager.setRenderer(clusterRenderer);
        ClusterRenderer clusterRenderer1 = new ClusterRenderer(getContext(), map, clusterManager1);
        clusterManager1.setRenderer(clusterRenderer1);
        addMarker();
        clusterManager.cluster();
        clusterManager1.cluster();
    }
