Je travaille sur une application Android, où il y a 2 types d'utilisateurs. Lorsque l'utilisateur s'inscrit ou se connecte au système, ils sont redirigés vers le même écran d'accueil et voient le fragment de vue différent gonflé en fonction de leur type. J'ai pu y parvenir en utilisant les préférences partagées lors de la première inscription. Mon seul problème est que, si l'utilisateur se déconnecte et tente ensuite de se reconnecter, quel que soit le type d'utilisateur, le même écran d'accueil est chargé. Je doute, l'activité utilise le dernier ensemble Préférences partagées.Préférences partagées renvoie toujours la même valeur
Dans mon fragment, basé sur userType, je gonfle le fichier xml correspondant. Mon exigence est, lorsque l'utilisateur se connecte, comment gonfler le fichier XML correspondant. comment puis-je obtenir les préférences partagées dans SignInActivity pour charger le fragment xml correspondant.
Voici ce que j'ai essayé jusqu'ici.

Lorsque l'utilisateur se connecte à l'application, comment je charger le xml fragment respectif? Qu'est-ce que je rate? Aide aimablement.
