为什么在Android中放大或缩小时不显示群集标记图标？ [英] Why cluster marker icon not showing when zoom in or zoom out in android

问题描述

我试图在我的地图上实现一个集群标记，首先，它显示集群标记，但是当我放大时，展开并显示白色方块，我将添加一些图像以更好地解释它。 / p>

  public class MyItem implements ClusterItem {
 private final LatLng mPosition; 
 String Title =; 
 int Icon; 
 $ b public MyItem（double lat，double lng，String title，int icon）{
 mPosition = new LatLng（lat，lng）; 
 Title = title; 
 Icon =图标; 
} 
 
 @Override 
 public LatLng getPosition（）{
 return mPosition; 
} 
 
 public String getTitle（）{
 return Title; 
} 
 
 public int getIcon（）{
 return Icon; 
} 
} 
 class OwnIconRendered extends DefaultClusterRenderer< MyItem> {
 
 
 public OwnIconRendered（）{
 super（MapActivity.this，googleMap，mClusterManager）; 
 
 
 
 @Override 
 protected void onBeforeClusterItemRendered（MyItem item，MarkerOptions markerOptions）{
 markerOptions.icon（BitmapDescriptorFactory.fromResource（item.getIcon（ ）））; 
 markerOptions.title（item.getTitle（））; 
 super.onBeforeClusterItemRendered（item，markerOptions）; 
 
 
 
 $ b @Override 
保护无效onBeforeClusterRendered（集群< MyItem>集群，MarkerOptions markerOptions）{
 super.onBeforeClusterRendered（集群，markerOptions）; 
} 
 
} 
  

解决方案

gmaps-api-issues存在一个未解决的问题，请看这里： https://code.google.com/p/gmaps-api-issues/issues/detail?id=9765

另请看这里：谷歌地图标记被替换为在缩放时绑定矩形

还介绍了一些解决方法。

        private final LatLng mPosition;
        String Title = "";
        int Icon;

        public MyItem(double lat, double lng, String title, int icon) {
            mPosition = new LatLng(lat, lng);
            Title = title;
            Icon = icon;
        }

        @Override
        public LatLng getPosition() {
            return mPosition;
        }

        public String getTitle() {
            return Title;
        }

        public int getIcon() {
            return Icon;
        }
    }
class OwnIconRendered extends DefaultClusterRenderer<MyItem> {


        public OwnIconRendered() {
            super(MapActivity.this, googleMap, mClusterManager);

        }

        @Override
        protected void onBeforeClusterItemRendered(MyItem item, MarkerOptions markerOptions) {
            markerOptions.icon(BitmapDescriptorFactory.fromResource(item.getIcon()));
            markerOptions.title(item.getTitle());
            super.onBeforeClusterItemRendered(item, markerOptions);
        }



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

    }

解决方案

There is an opened issue on gmaps-api-issues, look here: https://code.google.com/p/gmaps-api-issues/issues/detail?id=9765

Also look here: Google map marker is replaced by bounding rectangle on zoom

Some workarounds are also described there.
