J'ai une activité avec la disposition d'armature. Lorsque vous cliquez sur les options dans le tiroir de navigation, le fragment spécifique est ouvert. J'essayais d'implémenter observablescrollview dans mon fragment. https://github.com/ksoichiro/Android-ObservableScrollView. Je suis capable de l'implémenter mais je ne reçois pas l'icône hamburger dans la barre d'action. Je me suis rendu compte qu'il doit être livré avec le drawertoggle mais cela réside dans ma mainactivité. Comment l'obtenir dans mon fragment? Les utilisateurs peuvent même pas réaliser la présence d'un tiroir de navigation sans elle. Il était disponible lorsque j'utilisais une barre d'outils dans app_bar_main.xml. J'espère avoir été clair. S'il vous plaît laissez-moi savoir si vous avez besoin d'autres informations. Aide un débutant à sortir. Merci d'avance.ObservableScrollView icône hamburger manquant
Voici les captures d'écran.
