Question

Ich muss alle ausgewählten Radio-Button-Tags und Gruppenname erhalten, nachdem Benutzer klicken auf Appbar-Schaltfläche übermitteln und speichern Sie es in einer Liste.

Wenn i = „Answer_Checked“ Geprüft verwenden, Liste über geschrieben, wenn ich in Frage eines anderen Radiobutton klicken 2
