J'ai un contrôle ListView dans ma disposition d'activité principale. Sur chaque article de ma ListView, j'ai un bouton pour afficher les détails (ouverture d'une nouvelle activité) et afficher une carte (ouvre une application Google Maps externe). Le problème que j'ai est que je voudrais que l'utilisateur puisse cliquer sur l'élément ListView lui-même (pas un bouton) afin que la carte (à l'intérieur du fragment qui est au-dessus de la ListView) puisse être mise à jour. Pour une raison quelconque, mon événement ListView.itemclick ne s'exécute pas lorsque je clique sur un élément ListView. Dois-je ajouter quelque chose à mon code pour que cela fonctionne? J'ai parcouru le web et trouvé plusieurs suggestions pour corriger cela, mais rien ne fonctionne.ListView ItemClick ne répond pas
