                dialog.dismiss();

                try{
                    JSONObject obj = new JSONObject(response);
                    JSONArray arr = obj.getJSONArray("daftar_taxi");

                    for (int i = 0; i < arr.length(); i++) {
                        JSONObject c = arr.getJSONObject(i);
                        Taxi taxi = new Taxi();
                        taxi.setNamataxi(c.getString("mitra_nama"));
                        taxi.setThumbnailUrl(c.getString("image"));
                        taxi.setWaktu(c.getString("wkt_berangkat") + " - " + c.getString("wkt_sampai"));
                        taxi.setKursi("Kursi yang tersedia: " + c.getInt("jml_kursi"));
                        taxi.setTarif(c.getInt("tarif"));
                        taxiList.add(taxi);
                        Log.d(TAG, taxiList.toString());
                    }
                }catch (JSONException e) {
                    e.printStackTrace();
                }

            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                Log.e(TAG, "Error: " + error.getMessage());
                dialog.dismiss();
                Toast.makeText(getApplicationContext(),
                        error.getMessage(), Toast.LENGTH_SHORT).show();
            }
        }){

            @Override
            protected Map<String, String> getParams() {
                Map<String, String> params = new HashMap<String, String>();
                params.put("dari", textkodeasal_btn);
                params.put("ke", textkodetujuan_btn);
                params.put("jml_penumpang", jml_penumpang);
