OnMarkerClick在一个循环中

Question

虽然试图开发一个具有多个标记的地图应用程序，当点击标记时允许显示带有信息的弹出窗口，但在显示信息时我遇到了这个问题（它必须是不同的信息根据循环顺序，但它始终要求变量需要是最终的），但我仍然保持对所有弹出窗口（最后一条记录的值）具有相同的结果，即使我将变量设置为全局，对不起，我的英语和请帮助。

@Override 
protected void onResume() { 
super.onResume(); 
if(broadcastReceiver == null){ 
    broadcastReceiver = new BroadcastReceiver() { 
     @Override 
     public void onReceive(Context context, Intent intent) { 

Response.Listener<String> responseListener =new Response.Listener<String>() { 

       @Override 
       public void onResponse(String response) { 
        if(response== null){ 

         Toast.makeText(getApplicationContext(),response,Toast.LENGTH_LONG); 

        } 
        else { 
         try { 
          jsonObject = new JSONObject(response); 
           jsonArray = jsonObject.getJSONArray("response"); 
          int i=0 ; 
          int id,e; 
          Double lt,lg; 
          while (i<jsonArray.length()) { 
           jo = jsonArray.getJSONObject(i); 
           e= jo.getInt("etat"); 

           id= jo.getInt("driver_id"); 

           lt=jo.getDouble("latitude"); 

           lg= jo.getDouble("longitude"); 


           map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() { 
            @Override 
            public boolean onMarkerClick(Marker marker) { 
             if(marker.getTitle() != null){ 
              return true; 
             }else{ 

              layoutInflater = (LayoutInflater) getApplicationContext().getSystemService(LAYOUT_INFLATER_SERVICE); 
              ViewGroup container = (ViewGroup) layoutInflater.inflate(R.layout.popup,null); 

              popupWindow = new PopupWindow(container, 500,500,true); 
              popupWindow.showAtLocation(relativeLayout, Gravity.NO_GRAVITY, 100,100);

              tvNom.setText(id +""); 

              container.setOnTouchListener(new View.OnTouchListener() { 
               @Override

                popupWindow.dismiss(); 
                return true; 
               } 
              }); 


              return false;} 
            } 
           }); 
           if(e==0) { 
            marker = markerMap.get(d); 
            if (marker != null) { 
             marker.remove();

            } else {

    }; 
} 
registerReceiver(broadcastReceiver, new IntentFilter("location_update"));

正如您所指出的，您的所有侦听器都只添加到地图对象中。 API为附加每个标记对象的不同信息提供了一个名为标记的属性。

在标记对象上使用setTag（Object）。

无论你声明的标记，依次通过它们附加您想要的标签：

for(int i=0; i < allMarkers.length; i++) 
    marker.setTag(); 

，然后分配监听器，如：

map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() { 
           @Override 
           public boolean onMarkerClick(Marker marker) { 
            if(marker.getTitle() != null){ 
             return true; 
            }else{ 

             layoutInflater = (LayoutInflater) getApplicationContext().getSystemService(LAYOUT_INFLATER_SERVICE); 
             ViewGroup container = (ViewGroup) layoutInflater.inflate(R.layout.popup,null); 

             popupWindow = new PopupWindow(container, 500,500,true); 
             popupWindow.showAtLocation(relativeLayout, Gravity.NO_GRAVITY, 100,100); 
             TextView tvNom= (TextView) container.findViewById(R.id.tvNom); 
             //---------retrieve this marker's tag - could be Integer or any other Object. 
             int id = (Integer)marker.getTag(); 

             tvNom.setText(id +""); 

             container.setOnTouchListener(new View.OnTouchListener() { 
              @Override 
              public boolean onTouch(View view, MotionEvent motionEvent) { 
               popupWindow.dismiss(); 
               return true; 
              } 
             }); 


             return false;} 
           } 
          });
