Problème activity/ onglet
Bonjour, je suis actuellement en train de faire une application android. J'ai tester une galerie de photos dans une application séparée et celle-ci fonctionne. Puis dans mon application principale j'ai créé des onglets et j''ai voulu mettre ma galerie dans un des onglets, mais ceci ne marche pas, donc je fais appel à vous afin de m'aider.
voici l'activité principale qui crée les onglets:
