Ich entwickle eine Schuldenmanager App, wo Sie Personen und Geldbeträge hinzufügen können, die Sie ihnen schulden oder die sie Ihnen schulden. Die Personen sollten in einem ListView und die Schulden in einem ListView innerhalb der Personeneinträge angezeigt werden. Zur Zeit füge ich zwei Personen mit jeweils zwei Schuldeneinträgen als Dummy-Daten hinzu. Beide Personen werden im äußeren ListView angezeigt, es wird jedoch jeweils nur eine Schuldposition angezeigt.ListView in ListView zeigt nur einen Eintrag
Irgendeine Idee?
Ich habe bereits einige verwandte Fragen zu diesem Thema gelesen, aber ich fand keine Lösung.
