Answer 1

You should add all those values to a JSONArray and then add this JSONArray to your JSONObject. You could also add all objects to a simple array and then get the corresponding JSONArray by calling new JSONArray(your_array);

Answer 2

将有效负载的对象添加到JSONArray ，然后使用JSONArray.toString()将有效负载作为requestBody传递给JsonRequest 。
