Bitte posten Sie Ihre logcat Fehler. – DaveNOTDavid
in Bezug auf Ihren Code ist nicht nach Java-Konventionen und haben mehrere Fehler. – Pavan
Zuerst haben Sie viele Copy Paste Fehler (findViewById Teile). Zweitens ist Ihre Logik beim Überprüfen von Feldern schlecht. Bitte überarbeiten Sie sie und bearbeiten Sie Ihre Frage. –
