android - 如何在 android 中设置谷歌地图标记的可见性？

Question

在带有谷歌标记的应用程序中，我需要根据checkbox 的检查来设置marker 的可见性。我在一个 java 类中编写了谷歌地图标记的代码，而复选框在另一个 java 类中。

我的代码是:

AgentTree.java

package com.extraslice.gmobile;

import java.util.ArrayList;
import java.util.HashMap;

import org.json.JSONArray;
import org.json.JSONObject;

import android.content.Context;
import android.os.AsyncTask;
import android.util.Log;
import android.widget.SimpleAdapter;

import com.extraslice.gmobile.json.JsonImplementation;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class AgentTree extends AsyncTask<Void, Void, Void> {

    Context mContext;
    String mSeesionID;
    public static Marker agentmarker;
    AgentDetailsListener listener;
    public static SimpleAdapter sa;
    public static ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
    MapImageClassification map_obj;

    public AgentTree(Context context, String sessionID,AgentDetailsListener cListner) {
        mContext = context;
        mSeesionID = sessionID;
        listener=cListner;
        map_obj = new MapImageClassification();
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected Void doInBackground(Void... params) {
        try {


            //Log.i("SESSION ID AGENT", ""+mSeesionID);
            String stringRsp= JsonImplementation.jsonresp(GreaterActivity.main_url+"mandell-mvc/agent/giGetOrgGroupList/?sessionid="+GreaterActivity.temp_sessid);
            //get.setHeader("Accept", "application/json");

            Log.i("Response", ""+stringRsp);

            ListView agent_list=(ListView)((Activity)mContext).findViewById(R.id.agent_list);
            agent_list.setAdapter(sa);*/

            for(int i =0;i<AgentTree.list.size();i++)
        {
                double long_tude = 0;

                if((AgentTree.list.get(i).get("groupagents")).equals("GROUP"))

                    } catch (NumberFormatException e) {
                        e.printStackTrace();

                    *LatLng latLng = new LatLng(lat_tude,long_tude);
                agentmarker=    MainActivity.googleMap.addMarker(new MarkerOptions()
                    .position(latLng)
                    .title(""+agentid)
                    .snippet("agents")
                    .icon(BitmapDescriptorFactory.fromResource(map_icon))
                            );*
                    //map_icon=0;

                    /*if(MainActivity.org_chk.isChecked()==true){
                    agentmarker.setVisible(false);
                    }
                    else if(MainActivity.org_chk.isChecked()==false){
                        agentmarker.setVisible(true);
                    }*/
                    /** Add snippet() if necessary*********/
                }
            }

            listener.onComplete();
        }
        super.onPostExecute(result);
    }

    interface AgentDetailsListener 
    {
        void onComplete();
    }

}

显示标记的代码是:

            LatLng latLng = new LatLng(lat_tude,long_tude);
        agentmarker=    MainActivity.googleMap.addMarker(new MarkerOptions()
            .position(latLng)
            .title(""+agentid)
            .snippet("agents")
            .icon(BitmapDescriptorFactory.fromResource(map_icon))
                    );

我需要在另一个类中设置这个标记的可见性，我该如何实现？

尝试使用marker.setVisible(true) 或marker.setVisible(false)
