Volley send JSONObject to server with POST method

Question

I want to send a jsonobject with below format to server by using volley library { \"user_id\": 12, \"answers\": { \"11\": 3,

Answer 1

use the following sample code

RequestQueue queue = Volley.newRequestQueue(this);

private void serverFronJsonObjReq() {
showProgressDialog();


        Map postParam= new HashMap();
        postParam.put("username", "singh@gmail.com");
        postParam.put("password", "123456");


JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
        Const.BASE_URL_LOGIN, new JSONObject(postParam),
        new Response.Listener() {

            @Override
            public void onResponse(JSONObject response) {
                Log.d(TAG, response.toString());
                msgResponse.setText(response.toString());
                hideProgressDialog();
            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d(TAG, "Error: " + error.getMessage());
                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;
    }



};

jsonObjReq.setTag(TAG);
// Adding request to request queue
queue.add(jsonObjReq);

// Cancelling request
/* if (queue!= null) {
queue.cancelAll(TAG);
} */

}
