Ich verwende Koordinatorlayout innerhalb des Schubladenlayouts. Ich möchte eine Symbolleiste zum automatischen Ausblenden anzeigen und darin ein Filmplakat verwenden, das beim Scrollen von Filmdetails minimiert wird. Meine App verwendet auch ein Schubladenlayout. Hier ist mein Layout-XML activity_coordinator_layout
