Bonjour à tous,

Je suis bloqué depuis plusieurs jours maintenant, j'essaye de mettre en place un système de favoris sur mon application.

J'utilise l'API : NewsAPI, et j'ai 2 fragments, un "home" qui ressence les derniers articles et un "dashboard" qui devra ressencer les articles mis en favoris grace à mon image bookmark, qui lorsque je clique dessus copie l'article dans l'onglet Dashboard.

Mais je n'arrive pas à faire cela, j'ai donc besoin de votre aide.

J'ai un deuxième soucis, lorsque je suis sur le premier onglet / fragment, et que je change puis reviens sur le fragment principal mon appli crash, je sais pas si quelqu'un aurait une idée pourquoi ça fait cela.

Voici le code de mon ArticleAdapter.kt :
