Holen Sie sich den richtigen Cursor in CustomCursor Adapater getView ()
Ich habe einen benutzerdefinierten Cursoradapter, bei dem jede Zeile aus einem Kontrollkästchen, einer Textansicht und einer Schaltfläche besteht. Die Schaltfläche ist anfänglich auf GONE gesetzt, wenn der Benutzer das Kontrollkästchen aktiviert, das die Schaltfläche anzeigen soll, damit der Benutzer darauf klicken und die entsprechende Zeile löschen kann.
Mein Problem ist, dass ich in meinem getView () nicht den richtigen Cursor bekomme, also immer weitercursorOutOfBoundsExceptions.
Ich möchte das bindView () auch entfernen, wenn ich es nicht mehr benötige.
