zusammenklappbar Symbolleiste Kollabieren

Question

nicht Wie man oben sehen kann, wenn ich von ‚Blattpflanzen‘ blättern, kollabiert die CollapsibleToolbar wie erwartet, aber wenn ich von jedem Produktbild ziehen, die Seite scrollt unter AppBarLayout. Warum passiert das und wie kann man das beheben? Ich habe versucht, VerticalRecyclerView.setNestedScrolling auf false zu setzen, aber das hat nicht funktioniert.

Answer 1

setNestedScrollingEnabled (false) auf innere Horizontal RecyclerView löste dieses Problem für mich.
