Bonjour son été 2 jours je suis à la recherche d'une solution pour cela et je n'ai toujours aucune idée de comment faire, je veux faire un balayage vers la gauche et droite également réorganiser vue recycler, Lorsque l'utilisateur balayez elle sera automatiquement listée dans la liste complétée et si elle est balayée à gauche, elle supprimera l'élément de la liste dans la vue de recyclage. L'utilisateur peut également réorganiser l'élément de liste.Ajout de glisser et de réorganiser à une vue de recyclage
est ici activité principale:
