J'ai mis à jour le fichier java comment l'utilisateur peut-il cliquer sur un backpress du fragment à cette maison et sur le double pour arrêter l'application ??Comment avoir onbackpress sur le tiroir de navigation (fragments)

Pourquoi vous commencez une activité 'onBackPressed()'? –
J'essayais juste d'un clic pour aller à la page principale –
