android中集群组的自定义图标

我想用我的可绘制图标更改defult群集组图标.
请检查我的集群程序代码.

MyClusterRenderer.java

    public  class MyClusterRenderer extends DefaultClusterRenderer<MyItem> {

          public MyClusterRenderer(Context context, GoogleMap map,
                                   ClusterManager<MyItem> clusterManager) {
              super(context, map, clusterManager);

          }

          @Override
          protected void onBeforeClusterItemRendered(MyItem item, MarkerOptions markerOptions) {
              super.onBeforeClusterItemRendered(item, markerOptions);

 markerOptions.title("").icon(BitmapDescriptorFactory.fromresource(R.mipmap.location_both));// for marker
      }

          @Override
          protected void onClusterItemRendered(final MyItem clusterItem, Marker marker) {
              super.onClusterItemRendered(clusterItem, marker);

          }


      }

安装片段中的代码

  googleMap.clear();
        mClusterManager = new ClusterManager<MyItem>(getActivity(), googleMap);

        googleMap.setonMarkerClickListener(mClusterManager);
        googleMap.setonCamerachangelistener(mClusterManager);
        readItems();
        mClusterManager.setRenderer(new MyClusterRenderer(getActivity(), googleMap, mClusterManager));

解决方法:

尝试在onBeforeClusterRendered方法而不是onBeforeClusterItemRendered方法中更改Cluster图标：

@Override
protected void onBeforeClusterRendered(Cluster<MyItem> cluster, MarkerOptions markerOptions) {

    markerOptions.icon(BitmapDescriptorFactory.fromresource(R.mipmap.location_both));

}
