Comment supprimer des cases à cocher de la liste ?

Question

J'ai 50 éléments dans la liste. Maintenant, j'ai coché 10 éléments, alors comment faire pour que ces 10 éléments cochés soient supprimés de la liste lorsque je clique sur le bouton de suppression.

Voici mon code

Actualisez à nouveau la liste lorsque vous avez sélectionné la case à cocher et que vous avez appuyé sur le bouton de suppression. Cela signifie que vous devez à nouveau paramétrer l'adaptateur pour la vue en liste après que les éléments ont été supprimés. Merci de votre compréhension.
