android– 地图聚类 – 最大缩放标记仍然聚集

概述我正在使用androidmapsutils在googlemapsapiv2上聚类标记.它工作正常,但当我添加2000个标记时,在最大缩放时它仍然是聚类的(标记仍然有数字)：这是我用标记填充地图的方法：publicvoidgetRiverData(Stringstate,Stringtype){URL=getResources().getString(R.strin

我正在使用android maps utils在Google maps API v2上聚类标记.它工作正常,但当我添加2000个标记时,在最大缩放时它仍然是聚类的(标记仍然有数字)：

这是我用标记填充地图的方法：

谁能帮我？为什么不起作用？

解决方法:

您可以扩展DefaultClusterRenderer类并将最小标记设置为cluster.

public class InfoMarkerRenderer extends DefaultClusterRenderer<MyCustomMarker> {public InfoMarkerRenderer(Context context, GoogleMap map, ClusterManager<MyCustomMarker> clusterManager) {    super(context, map, clusterManager);    //constructor}@OverrIDeprotected voID onBeforeClusterItemRendered(final MyCustomMarker infomarker, MarkerOptions markerOptions) {      // you can change marker options}@OverrIDeprotected boolean shouldRenderAsCluster(Cluster cluster) {    return cluster.getSize() > 5; // if markers <=5 then not clustering}}
