Il n'est pas nécessaire d'envelopper 'CheckedTextView' dans un' RelativeLayout', de supprimer le wrapper 'RelativeLayout'. – Luksprog
@Luksprog wow qui a fonctionné. Je me demandais pourquoi la vérification et décocher est liée à cela. –
@Luksprog J'ai un bouton CheckAll que je veux vérifier/décocher tous les éléments en fonction de l'état. une idée de comment cela peut-il être fait? –
