如何在Android中使用这种格式创建Json？

Question

I want to send this serialize Json in Soap web service parameter to get data from server. I don know how to serialize Json like below.

I am doing this -

JSONObject jsonObject = new JSONObject();
            try {

                JSONObject obj = new JSONObject();
                //obj.put("MeterSrNo", txtMeterSrMo.getText().toString());
                obj.put("MeterSrNo", txtMeterSrMo.getText().toString());
                jsonObject.put("obj", obj);
                jsonObject.put("SPName", "XXMFU_GETMobilityDetail");
            } catch (JSONException e) {
                e.printStackTrace();
            }

And its giving me below output-

{'obj':{"MeterSrNo":"5"},'SPName':'XXMFU_GETMobilityDetail'}

But i want below output. How can i achieve this?

"{'\obj\':{\"MeterSrNo\":\"5\"},'\SPName\':'XXMFU_GETMobilityDetail'}"

Answer 1

By using Gson Library you can do serialization and desertification.

Serialization

new Gson().toJson(object)

Deserialization

new Gson().fromJson(jsonString, MyClass.class);

Answer 2

Try following way,

  JSONObject jsonObject = new JSONObject();
  JSONObject jsonMeterObject = new JSONObject();

    try {
        jsonMeterObject.put("MeterSrNo","5");
        jsonObject.put("obj",jsonMeterObject);
        jsonObject.put("SPName","XXMFU_GETMobilityDetail");
    } catch (JSONException e) {
        e.printStackTrace();
    }

Output

{
"obj":{
"MeterSrNo":"5"
},
"SPName":"XXMFU_GETMobilityDetail"
}
