Answer 1

diesen Code

startActivity(new Intent(FormActivity.this, SubmitData.class)); 

innen onResponse (String response) Methode hinzufügen. Und entfernen Sie die Methode submitData aus der Datei SubmitData.java. Entfernen Sie auch android: onClick = "submitData" aus activity_form.xml-Datei.

Answer 2

Ich würde die Login-Schaltfläche eine AsyncTask aufrufen, und auf der onPostExecute() nach der Validierung der Informationen können Sie startenActivity() zu welcher Aktivität Sie öffnen möchten.
