It worked for can try this for calling with Volley Json Request and Response ith Java Code .

public void callLogin(String sMethodToCall, String sUserId, String sPass) {
        RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());

        JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
                Request.Method.POST, ConstantValues.ROOT_URL_LOCAL + sMethodToCall.toString().trim(), addJsonParams(sUserId, sPass),
//                JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, object,
                new Response.Listener() {
                    @Override
                    public void onResponse(JSONObject response) {
                        Log.d("onResponse", response.toString());
                        Toast.makeText(VolleyMethods.this, response.toString(), Toast.LENGTH_LONG).show(); // Test

                        parseResponse(response);
//                        msgResponse.setText(response.toString());
//                        hideProgressDialog();
                    }
                },
                new Response.ErrorListener() {

                    @Override
                    public void onErrorResponse(VolleyError error) {
                        VolleyLog.d("onErrorResponse", "Error: " + error.getMessage());
                        Toast.makeText(VolleyMethods.this, error.toString(), Toast.LENGTH_LONG).show();
//                hideProgressDialog();
                    }
                }) {

            /**
             * Passing some request headers
             */
            @Override
            public Map getHeaders() throws AuthFailureError {
                HashMap headers = new HashMap();
                headers.put("Content-Type", "application/json; charset=utf-8");
                return headers;
            }


        };

        requestQueue.add(jsonObjectRequest);
    }

    public JSONObject addJsonParams(String sUserId, String sPass) {
        JSONObject jsonobject = new JSONObject();
        try {
//            {"id":,"login":"secretary","password":"password"}

            ///***//
            Log.d("addJsonParams", "addJsonParams");

//            JSONObject jsonobject = new JSONObject();

//            JSONObject jsonobject_one = new JSONObject();
//
//            jsonobject_one.put("type", "event_and_offer");
//            jsonobject_one.put("devicetype", "I");
//
//            JSONObject jsonobject_TWO = new JSONObject();
//            jsonobject_TWO.put("value", "event");
//            JSONObject jsonobject = new JSONObject();
//
//            jsonobject.put("requestinfo", jsonobject_TWO);
//            jsonobject.put("request", jsonobject_one);

            jsonobject.put("id", "");
            jsonobject.put("login", sUserId); // sUserId
            jsonobject.put("password", sPass); // sPass


//            js.put("data", jsonobject.toString());

        } catch (JSONException e) {
            e.printStackTrace();
        }

        return jsonobject;
    }

    public void parseResponse(JSONObject response) {

        Boolean bIsSuccess = false; // Write according to your logic this is demo.
        try {
            JSONObject jObject = new JSONObject(String.valueOf(response));
            bIsSuccess = jObject.getBoolean("success");


        } catch (JSONException e) {
            e.printStackTrace();
            Toast.makeText(VolleyMethods.this, "" + e.toString(), Toast.LENGTH_LONG).show(); // Test
        }

    }
