Use CustomVolleyRequest as I use below

public class CustomVollyRequest extends Request<JSONObject> {
    private Listener<JSONObject> listener;
    private Map<String, String> params;

    public CustomVollyRequest(String url, Map<String, String> params, 
            Listener<JSONObject> reponseListener, 
            ErrorListener errorListener) {
        super(Method.GET, url, errorListener);
        this.listener = reponseListener;
        this.params = params;
    }

    public CustomVollyRequest(int method, String url, Map<String, String> params, 
            Listener<JSONObject> reponseListener, 
            ErrorListener errorListener) {
        super(method, url, errorListener);
        this.listener = reponseListener;
        this.params = params;
    }

    @Override
    protected Map<String, String> getParams() throws com.android.volley.AuthFailureError {
        return params;
    }

    @Override
    protected void deliverResponse(JSONObject response) {
        listener.onResponse(response);
    }

    @Override
    protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
        try {
            String jsonString = new String(response.data,     HttpHeaderParser.parseCharset(response.headers));
            return Response.success(new JSONObject(jsonString),
                HttpHeaderParser.parseCacheHeaders(response));
        } catch (UnsupportedEncodingException e) {
            return Response.error(new ParseError(e));
        } catch (JSONException je) {
            return Response.error(new ParseError(je));
    }
}

Use the above class as below

Map<String, String> params = new HashMap<>();
params.put("key",value);//put your parameters here
CustomVollyRequest jsObjRequest = new CustomVollyRequest(
        Request.Method.POST, url, params,
        new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                //Log.d("Response: ", response.toString());
            }
        }, 
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError response)
            {
                Log.d("Response: Error", response.toString());
            }
        }
);

Answer 2

For authentication, IMHO, you should override getHeaders instead of getParams, please try the following:

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
       Map<String, String> headers = new HashMap<>();                
       String credentials = "username:password";
       String auth = "Basic "
                        + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);
       headers.put("Content-Type", "application/json");
       headers.put("Authorization", auth);
       return headers;
}

Hope it helps!

just override this method

 @Override
        public Map<String, String> getHeaders() {
            String username ="danish@gmail.com";
            String password = "dani3173";
            String auth =new String(username + ":" + password);
            byte[] data = auth.getBytes();
            String base64 = Base64.encodeToString(data, Base64.NO_WRAP);
            HashMap<String, String> headers = new HashMap<String, String>();
            headers.put("Authorization",base64);
            headers.put("accept-language","EN");
            headers.put("Content-type","application/json");
            headers.put("Accept","application/json");
            return headers;
        }
