【问题描述】：

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，并且在单击 item（只有一个标记）时显示一条消息，以便我可以在它们之间做出差异。

这是我的代码，setOnClusterClickListener 和 setOnClusterItemClickListener 没有被调用，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);

【参考方案1】：

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;
    
);
