Horizontale RecyclerView in NestedScrollView, kann nicht vertikal scrollen

Ich versuchte jede Kombination aus diesem, einige Leute sagten, es ist ein Bug, aber ich denke, es ist etwas Kleines, das ich vermisse. Mit dem folgenden XML kann ich überhaupt nicht scrollen, nur der horizontale Scroll funktioniert.Horizontale RecyclerView in NestedScrollView, kann nicht vertikal scrollen
Ich habe eine Seiten-Scroll-RecyclerView, die ich nach links und rechts ziehen kann, aber die Seite hat mehr I Elemente als passen kann, daher die ScrollView.
Am Anfang war ich auf eine reduzierbare Symbolleiste, aber wenn ich CoordinatorLayout hinzufügen, ist die Aktivität leer.

Diese Zeile hinzufügen * mRecyclerView.setNestedScrollingEnabled (false); * in onCreate-Methode –
Versuchen Sie setNestedScrollingEnabled(false) zu Ihrem inneren Recyclerview hinzuzufügen.
https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html
setNestedScrollingEnabled

verschachtelte Scrollen für diese Ansicht aktivieren oder deaktivieren.

Wenn diese Eigenschaft auf "True" festgelegt ist, kann die Ansicht verschachtelte Bildlaufvorgänge mit einer kompatiblen übergeordneten Ansicht in der aktuellen Hierarchie initiieren. Wenn diese Ansicht das verschachtelte Scrollen nicht implementiert, wird dies keine Auswirkung haben. Durch das Deaktivieren des verschachtelten Scrollings, während ein verschachtelter Scroll ausgeführt wird, wird der verschachtelte Scroll angehalten.
