Je crée un RecyclerView qui accepte une liste d'objets Match. J'ai placé un onClickListener pour le listItem. Je veux mettre le Match à actif quand je clique sur ce listItem. Comment puis-je accéder à l'objet Match stocké dans un élément de liste particulier lorsque je clique dessus?RecyclerView - Obtention d'objets à partir de mon ViewHolder
Voici mon adaptateur/classe de la ViewHolder RecyclerView:
