Ich versuche, die Searchview-Funktion davon zu nehmen: github.com/Wrdlbrnft/Searchable-RecyclerView-Demo (kann nicht mehr als 2 Links, sorry)Android - Suche ist nicht repopulierende Ergebnisse/Liste nach Backspacing
ich habe versucht, es zu einem Projekt hinzuzufügen. Wenn ich dies tue, werden meine Ergebnisse jedoch gefiltert, aber sie werden nicht hinzugefügt, wenn ein Benutzer Änderungen oder Backspaces durchführt.
Der Code ist in der Nähe identisch. Ich habe nichts mit dem Adapter geändert.
