Hallo Ihr lieben. Ich habe mal wieder ein Problem, nachdem ich schon seit 2 Stunden im Internet am suchen bin und einfach keine Lösung finde. Kurzer Umriss: es handelt sich um eine BattleActivity.java die in ihrer .xml datei ein Framelayout enthält, indem eine von zwei Fragments angezeigt werden soll. Das Anzeigen läuft und scheinbar auch der Wechsel zwischen beiden. Nun, wenn die BattleActivity startet, soll zuerst BattleTextFragment geladen werden, zusammen mit einem von 3 Strings, der zufällig generiert wird. Wenn ich diese Funktion innerhalb des Fragments ablaufen lasse, funktioniert das auch prima, aber nun möchte ich (es ist ein Kampf Szenario) die zwei Fragments über die BattleActivity laufen lassen, dafür müsste ich nun die TextView innerhalb des BattleTextFragments durch BattleActivity verändern, indem ich eine Methode gerufen hätte, die man innerhalb des Fragments findet. Aber das scheitert und ich weiß nicht weiter.
