Wie füge ich vergessene Passwort-Links hinzu? Anmelden im Dialogfeld in Firebase?
ich in einem Warndialogfeld Zeichen in Form erschaffe, aber in diesem Dialogfeld möchte ich vergessen Passwort Link unten Zeichen hinzuzufügen, in der mich in einer anderen Aktivität verbinden wird. Ich habe viele Änderungen ausprobiert, aber es stürzt ab. Ich verwende Firebase-Authentifizierung in dieser App.App stürzt ab, wenn ich den Code In Hauptaktivität modifiziere und Fehler gibt. unten ist mein Main Java Code.

Ich verstehe nicht, warum Sie nicht eine TextView hinzufügen können und dann einen OnClickListener wie MaterialEditText edtEmail, die die neue Aktivität startet? Es sollte keinen Grund geben, warum Sie nicht können, da es bereits MaterialEditText edtEmail gibt. – CmosBattery
Ich habe versucht, aber das funktioniert nicht –
