Bonjour,
Je voudrais avoir une aide sur mon programme, en faite j'ai créer un objet produit " id , image , titre , description" et je dois faire un affichage GridView. j'ai trouvé comment le faire simplement mais mon probleme qe je doit utiliser une table produit donc j'ai créer avec sqlite puis a partir de la table je recupere l'image et le titre donc dans le cas ou j'ajout un nouveau produit dans la base donc l'image sera afficher dans la liste çàd dans GridView
voila les codes et comment je peux le modifier de tel sorte soit dynamiquement avec base de données.
