Ich bin neu bei Android und versuchen, eine einfache Schaltfläche zu implementieren, die eine Nachricht in einem Toast anzeigen sollte (schließlich wird es verwendet, um ein Konto zu erstellen). Aber nichts passiert, wenn ich den Knopf drücke, es werden auch keine Fehler auf dem Logcat angezeigt, also muss ich etwas Offensichtliches vermissen, aber ich kann es nicht finden !!Button funktioniert nicht in Android-Anwendung

Was mache ich falsch?
Was ist dieses aktivierte Attribut in der Schaltfläche XML? –
der Code scheint gut. – thedarkpassenger
aktiviert bedeutet, dass die Schaltfläche für die Benutzereingabe verfügbar ist, aber aus dem Code scheint alles in Ordnung – DZDomi
