Volley And Gson -sending A Post Request Using Jsonobjectrequest

I'm new here and I don't very well speak English, but I do my best to explain me. I have some problems with the Post request. This is my code: private void makeRequest() { Stri

Solution 1:

if you think the problem is with getParams, then with Volley you don't have to use the getParams, it knows how to deal with JSONObject so you can use:

String someurl = URL;

    Map<String, Object> jsonParams = newHashMap<>();
    jsonParams.put("someparam", getSomeParam());

    JsonObjectRequest request = newJsonObjectRequest(Request.Method.POST, someurl, newJSONObject(jsonParams),
            newResponse.Listener<JSONObject>()
            {
                @OverridepublicvoidonResponse(JSONObject response)
                {
                    Log.d(TAG + ": ", "Response: " + response.toString());
                    //do other stuff 
                }
            },
            newResponse.ErrorListener()
            {
                @OverridepublicvoidonErrorResponse(VolleyError error)
                {
                    if (null != error.networkResponse)
                    {
                        Log.d(TAG + ": ", "Error Response code: " + error.networkResponse.statusCode);
                    }
                }
            });

    requestQueue.add(request);

Also - make sure the variable names in Usuario class match the names you get back in your Json, if it doesn't match the variable in Usuario will be NULL by default.
