Question

在我的应用程序中，我在谷歌地图上放置了超过50K的标记。我想自定义标记群集渲染器。标记上显示的数字不正确，显示错误的数字，它不包含它在标记上显示的数字引脚。请帮我解决这个问题。我使用以下代码来聚类标记：

mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(51.503186, -0.126446), 10));

// Initialize the manager with the context and the map.
// (Activity extends context, so we can pass 'this' in the constructor.)
mClusterManager = new ClusterManager<MyItem>(this, mMap);
mClusterManager.setRenderer(new MyClusterRenderer<MyItem>(this, mMap,mClusterManager));

// Point the map's listeners at the listeners implemented by the cluster
// manager.
mMap.setOnCameraChangeListener(mClusterManager);
mMap.setOnMarkerClickListener(mClusterManager);

addItems();

添加项目的功能

private void addItems() {
    for (int i = 0; i < placesCoordinates.size(); i++) {
        MyItem offsetItem = new MyItem(placesCoordinates.get(i).getLat(), placesCoordinates.get(i).getLng());
        mClusterManager.addItem(offsetItem);
    }
}

在完成调试一整天之后，我发现问题不在于群集标记编号，实际上问题在于我的数据集。它包含多次类似的坐标。

如何自定义google marker群集渲染器？
