und dies ist mein Code-Parameter-Server zu schreiben:

for (int i = 0; i < arr.length(); i++) {

Taxi taxi = new Taxi();
taxi.setNamataxi(c.getString("mitra_nama"));
taxi.setThumbnailUrl(c.getString("image"));

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());

}){

Haben Sie versucht, Dummy-Listen nur zu Testzwecken hinzuzufügen? –
ja, ich habe ... und es ist in Ordnung – meeftah
Dann sagen Sie, Dummy-Liste wird in beiden angezeigt. Aber die Liste, die Sie vom Server holen mussten, wird nicht in einem echten Gerät angezeigt, oder? –
