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包含信息的弹出窗口，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顺序，但它一直要求变量需要是最终的）但我对所有弹出窗口（最后一个记录的值）保持相同的结果，即使我将变量设为全局，抱歉我的英语和请帮助。
@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);
TextView tvNom= (TextView) container.findViewById(R.id.tvNom);
tvNom.setText(id +"");
container.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
popupWindow.dismiss();
return true;
}
});
return false;}
}
});
if(e==0) {
marker = markerMap.get(d);
if (marker != null) {
marker.remove();
markerMap.remove(d);
} else {
markerMap.remove(d);
}
}
else{
if (markerMap.containsKey(id)) {
Intent intent= new Intent(MapActivity.this,InfoWindow.class);
intent.putExtra("id",id+"");
// Update the location.
marker = markerMap.get(id);
marker.remove();
markerMap.remove(id); //added
MarkerOptions markerOpt = new MarkerOptions()
.position(new LatLng(lt,lg)).visible(true);
marker = map.addMarker(markerOpt);
markerMap.put(id, marker);
} else {
MarkerOptions markerOpt = new MarkerOptions()
.position(new LatLng(lt, lg)).visible(true);
marker = map.addMarker(markerOpt);
markerMap.put(id, marker);
} }
i++;}
}catch (JSONException e) {
e.printStackTrace();
AlertDialog.Builder nbuilder = new AlertDialog.Builder(MapActivity.this);
nbuilder.setMessage("Error")
.setNegativeButton("Retry", null)
.create()
.show();
}
}
}
};
RetrieveCoordinates retrieve = new RetrieveCoordinates ( responseListener );
RequestQueue queue = Volley.newRequestQueue(MapActivity.this);
queue.add( retrieve);
}
};
}
registerReceiver(broadcastReceiver, new IntentFilter("location_update"));
}

正如您所指出的，所有侦听器都只添加到地图对象中。 API为每个标记对象附加不同信息提供的是一个名为 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，都可以通过它们来附加你想要的标记：
for(int i=0; i < allMarkers.length; i++)
marker.setTag();
然后分配监听器：
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;}
}
});
