Getting the value of JSONObject in android using volley library

Question

I want to get the value of JSONObject in android using volley library.

Here is my MainActvity.java code.

 String url = "http://someexample.com/signin.php";
        StringRequest postRequest = new StringRequest(Request.Method.POST, url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        try {
                            JSONObject jsonResponse = new JSONObject(response).getJSONObject("type");
                            String myObjAsString = jsonResponse.toString();

                            mTV.setText(myObjAsString.toString());

                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        error.printStackTrace();
                    }
                }
        ) {
            @Override
            protected Map<String, String> getParams() {
                Map<String, String> params = new HashMap<>();
                // the POST parameters:
                params.put("email", "example@outlook.com");
                params.put("password", "********");
                return params;
            }
        };
        Volley.newRequestQueue(this).add(postRequest);

Here is my web service response.

{
   "type":"1",
   "data":{
      "userID":"197",
      "name":"Hasnain",
      "email":"example@outlook.com",
      "paymentstatus":1
   },
   "title":"Message",
   "message":"User loged in successfully",
   "_explicitType":null
}

Here is my error stack .

I want to get the value of “type” object from the response.

"type" is not a JSON object. it is string look at the Rajesh jadav answer — Amol Sawant, Sep 08 '15 at 06:32
I am new to json. @AmolSawant96Kuli if you check my json reponse in this website http://www.jsoneditoronline.org/ it shows my response has five objects including "type". — hasnain_ahmad, Sep 08 '15 at 06:47

Error:

org.json.JSONException: Value 1 at type of type java.lang.String cannot be converted to JSONObject

From error log i can see that you are trying to convert JSONObject into String so you are getting JSONException.

You need to get type String value from JSONObject this way.

Try this code:

JSONObject jsonResponse = new JSONObject(response);
String myObjAsString = jsonResponse.getString("type");

instead of

JSONObject jsonResponse = new JSONObject(response).getJSONObject("type");
String myObjAsString = jsonResponse.toString();

I hope it helps!

Get your JSONObject with "type"

try {
     JSONObject jsonResponse = new JSONObject(response);
     String myObjAsString = jsonResponse.getString("type");
     mTV.setText(myObjAsString.toString());
}catch(JSONException e) {
  e.printStackTrace();
}

Its because you want a JSON object as a response but still you are using String request.Try JSON Object request in place of JSON String request.It will work
