如果我在onMapReady内添加我的clusterItem,如下所示

    @Override
    public void onMapReady(GoogleMap googleMap) {
        Log.d("CustomMapFragment","onMapReady");
        map = googleMap;
        map.getUiSettings().setAllGesturesEnabled(true);
        map.getUiSettings().setCompassEnabled(true);
        map.getUiSettings().setZoomGesturesEnabled(true);
        map.getUiSettings().setZoomControlsEnabled(true);

        mClusterManager.addItem(new MyMarker(23.748865, 90.411655, "a", new Resultset("112113","dsd")));
        mClusterManager.addItem(new MyMarker(23.749049, 90.411382, "b", new Resultset("112113","ddfdsd")));
        mClusterManager.addItem(new MyMarker(23.749129, 90.411088, "c", new Resultset("11211dsd3","dsd")));
        mClusterManager.addItem(new MyMarker(23.749241, 90.41068, "d", new Resultset("112113","fgdsd")));
        mClusterManager.addItem(new MyMarker(23.749183, 90.410257, "e", new Resultset("112113","qwdsd")));
    }

如果我在onMapReady中添加一些群集,则按预期方式进行群集工作。但我定期调用一个Web服务,它将集群项添加到地图

UIUpdater mUIUpdater = new UIUpdater(new Runnable() {
    @Override
    public void run() {
       //running a web service 
        mClusterManager.addItem(new MyMarker(lat, longitude, memberListModel.get(i).getFirstName()+" "+ memberListModel.get(i).getLastName(), memberListModel.get(i)));
    }
}

在调用周期性任务后,标记会添加到地图中,但是如果我放大或缩小地图,标记最初是不可见的,则没有聚类效果,标记是可见的,但没有聚类效果。

我添加了以下依赖项

compile "com.google.android.gms:play-services-maps:9.4.0"
compile "com.google.android.gms:play-services-location:9.4.0"
compile 'com.google.maps.android:android-maps-utils:0.4+'

在片段的onResume中我启动了周期性任务运行器并在onPause中停止

@Override
public void onResume() {
    super.onResume();
    mUIUpdater.startUpdates();

}

@Override
public void onPause() {
    super.onPause();
    mUIUpdater.stopUpdates();

}

如何添加群集项以在定期任务运行器内进行映射?

添加群集项后,您应该调用以下方法。

mClusterManager.clearItems();
mClusterManager.cluster();

答案 1 :(得分:2)

public class TheClusterItem implements ClusterItem {
    ...
}

TheClusterItem item = new TheClusterItem(...);
mClusterManager.addItem(item); // or list of items
mClusterManager.cluster();

添加项目并调用群集方法后,将在适当的区域更新群集。
