Bonsoir,
j'aimerais afficher mon tab bar dans toutes les activités de mon application. J'ai essayé de suivre ce tutoriel http://gamma-point.com/content/andro...ab-tabactivity mais lorsque je clique sur l'onglet voulu, l'activité n'apparait pas avec le tab bar, et lorsque je clique sur le bouton qui emmène vers l'activity suivante celle-ce apparait avec le tab bar. Sachant que mon logCat n'affiche aucune erreur.
voilà mon code (correspondant à l'activité dans laquelle le tab bar ne s'affiche pas)
Code : Sélectionner tout - Visualiser dans une fenêtre à part
