java - 从java中的json对象获取正确的输出

Question

我的代码是:

 JSONObject jChild=new JSONObject();
         JSONObject jParent=new JSONObject();
            for (Product p : boxAdapter.getBox()) {
              if (p.checked){
                try {
                    jChild.put("uid", p.uid);
                list.add(String.valueOf(jChild));

                    //list.add(String.valueOf(jParent));
                } catch (JSONException e) {
                    e.printStackTrace();
                }
              }
            }
            jParent.put("users", list);

          // Toast.makeText(this, ""+jParent, Toast.LENGTH_LONG).show();
            Log.v("TakeAttendance","JSONpARENT "+String.valueOf(jParent));

输出:

{"users":"[{\"uid\":\"4\"}, {\"uid\":\"5\"}, {\"uid\":\"6\"}]"}

我真正需要的:

  {users: [
    {
    name: "acx",
    uid: "2"
    },

    {
    name: "test",
    uid: "6"
    },

    {
    name: "ccc",
    uid: "11"
    }
    ]
    }

JSON 要求键和值都是字符串。如果您需要 pretty-print JSON 对象，请尝试 pretty-print-json-in-java
