Horizontale Recycler-Ansicht in nestedScrollView funktioniert nicht richtig

Question

Mein horizontaler RecyclerView in nestedScrollView funktioniert nicht ordnungsgemäß. Wenn ich die RecyclerView horizontal scrolle, fängt meine NestedScrollView die Eingabe als vertikales Scroll und nur einmal auf vier Mal das horizontale Scroll funktioniert gut. Wie kann ich es lösen? Ich habe keine Probleme mit normalem ScrollView. Ich habe es noch mit horizontalScrollView versucht und ich habe das gleiche Problem. Ich muss nestedScrollView verwenden, da ich Collapse ein Bild und die Symbolleiste verwenden möchte.

Hier ist mein xml-Code:

try Recyclerview nestedScrolling Aktiviert falsch zu ändern. in Ihrem Code setzen Sie es als wahr

Änderung

Um

android:nestedScrollingEnabled="false"
