这是我的代码：

 StringRequest stringRequest = new StringRequest(Request.Method.POST, AppConfig.URL_Marker,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {

                        try {
                            JSONArray jsonArray = new JSONArray(response);


                            for (int i = 0; i < jsonArray.length(); i++) {
                                jresponse = jsonArray.getJSONObject(i);
                                latitude = Double.parseDouble(jresponse.getString("lat"));
                                longitude = Double.parseDouble(jresponse.getString("lng"));


                                mMap.addMarker(new MarkerOptions()
                                        .position(new LatLng(latitude,longitude))
                                        .icon(BitmapDescriptorFactory.fromResource(R.drawable.tram_48))
                                        .draggable(true));

                            }


                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                        //pDialog.dismiss();

                    }

                }

Answer 1

你可能想试试这个：

try{
     JSONObject jsonObj = new JSONObject(response);
     JSONArray jsonArray = jsonObj.getJSONArray("markers");

因为据我所知，这应该可行。
