标记聚类默认聚类出现

Question

因此，基本上我希望像文档中所示的那样对自定义标记进行聚类。只是没有图片，https://developers.google.com/maps/documentation/android-sdk/utility/marker-clustering#maps_android_utils_clustering_info_window-java。我很难理解为什么缩放地图时会出现默认标记

​

我的CustomMarker类如下所示

    public class CustomMarker extends DefaultClusterRenderer<MapMarker> {
    private final IconGenerator iconGenerator;
    private final IconGenerator clusterIconGenerator;
    private final ImageView imageView;
    private final int markerWidth;
    private final int markerHeight;

    public CustomMarker(Context context,
                        GoogleMap map,
                        ClusterManager<MapMarker> clusterManager) {

        super(context, map, clusterManager);
        int padding = 0;
        markerWidth = 200;
        markerHeight = 200;
        clusterIconGenerator = new IconGenerator(getActivity());
        
        imageView = new ImageView(getActivity());
        imageView.setLayoutParams(new ViewGroup.LayoutParams(markerWidth, markerHeight));
        imageView.setPadding(padding, padding, padding, padding);

        iconGenerator = new IconGenerator(getActivity());
        iconGenerator.setContentView(imageView);
    }

    @Override
    protected void onBeforeClusterItemRendered(@NonNull MapMarker item, @NonNull MarkerOptions markerOptions) {
        imageView.setImageURI(Uri.parse(item.getPicture()));
        Bitmap icon = iconGenerator.makeIcon();
        markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon)).title(item.getTitle());
        super.onBeforeClusterItemRendered(item, markerOptions);

    }



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

        markerOptions.visible(false);
        Bitmap icon = clusterIconGenerator.makeIcon(String.valueOf(cluster.getSize()));
        markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon));
        markerOptions.visible(true);
 }

    @Override
    protected boolean shouldRenderAsCluster(Cluster cluster) {
        return cluster.getSize() > 2;
    }
}

在我设置标记的函数中，我设置了以下内容

感谢您的任何帮助！

出现默认集群是因为我没有覆盖

 protected void onClusterUpdated(@NonNull Cluster<MapMarker> cluster, @NonNull com.google.android.gms.maps.model.Marker marker)

此方法应与您的onBeforeClusterRendered相同
