循环内的 OnMarkerClick

Question

在尝试开发具有多个标记的地图应用程序时，允许在单击标记时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（根据循环，它必须是不同的信息订单，但它一直要求变量必须是最终的），但即使我将变量设为全局变量，我对所有弹出窗口（最后一条记录的值）的结果都相同，对不起我的英语，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");

Answer 1

正如您所指出的，您的所有侦听器都仅添加到地图对象中。 API 提供的用于在每个标记对象上附加不同信息的是一个名为 tag 的属性。

在标记对象上使用 setTag(Object)。

无论你在哪里声明了你的标记，循环遍历它们并附加你想要的标签：

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

然后像这样分配监听器：

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;}
                                }
                            });
