Android: GridView-Set nicht scrollbar?

Question

Ich versuche Filterabschnitt durch gridView zu tun. In einem großen Bildschirm ist es in Ordnung. Aber wenn es kleiner Bildschirm ist, funktioniert nicht richtig. (Eine Ansicht ist zwei oder drei Mal, einige verschwinden). Dies liegt daran, dass die Schrumpfung und der Bildlauf von gridView item angezeigt werden. Also versuche ich, gridView scroll zu entfernen.

Meine Tätigkeit ist.

Answer 1

Versuchen Sie, diese

ViewCompat.setNestedScrollingEnabled(gridView, true); 

Answer 2

nicht GridView innen ScrollView Verwenden Sie, weil beide Scrolling-Funktionalität hat und aufgrund dieser wird es nicht richtig funktionieren.

Verwenden Sie NestedScrollView anstelle von ScrollView.

NestedScrollView ist wie ScrollView, aber es unterstützt sowohl als nested Scrollen parent und child auf den neuen und alten Versionen von Android handeln. Verschachteltes Scrollen ist standardmäßig aktiviert.

Siehe documentation.

Aktualisieren Sie Ihre Layout-Struktur wie folgt:
