Question

我正在开发基于地图的应用程序，我使用集群来安排标记。它工作正常。现在，我需要在单击clusterManager时显示一条消息，当我单击item（只有一个标记）时，我可以在它们之间产生差异。

这是我的代码，setOnClusterClickListener并且setOnClusterItemClickListener没有调用，所以请问我的代码出了什么问题。

    mClusterManager = new ClusterManager<MyItem>(this, getMap());

    getMap().setOnCameraChangeListener(mClusterManager);
    try {
        readItems();
    } catch (JSONException e) {
        Toast.makeText(this, "Problem reading list of markers.", Toast.LENGTH_LONG).show();
    }

    mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<MyItem>() {
        @Override
        public boolean onClusterClick(Cluster<MyItem> cluster) {
            Log.d("cluster","clicked");
            return true;
        }
    });
    mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<MyItem>() {
        @Override
        public boolean onClusterItemClick(MyItem item) {
            Log.d("cluster item","clicked");
            return true;
        }
    });
    getMap().setOnMarkerClickListener(mClusterManager);

你应该在setOnClusterClickListener和setOnClusterItemClickListener之前调用setOnMarkerClickListener

mClusterManager = new ClusterManager<MyItem>(this, getMap());
getMap().setOnMarkerClickListener(mClusterManager); // 
getMap().setOnCameraChangeListener(mClusterManager);
try {
    readItems();
} catch (JSONException e) {
    Toast.makeText(this, "Problem reading list of markers.", Toast.LENGTH_LONG).show();
}

mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<MyItem>() {
    @Override
    public boolean onClusterClick(Cluster<MyItem> cluster) {
        Log.d("cluster","clicked");
        return true;
    }
});
mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<MyItem>() {
    @Override
    public boolean onClusterItemClick(MyItem item) {
        Log.d("cluster item","clicked");
        return true;
    }
});
