So scrollen Sie beim Scrollen von RecyclerView in der unteren Leiste nach oben / unten
it der kürzlich von Google veröffentlichten Design-Support-Bibliothek wurden einige coole neue Ansichten eingeführt. Mit einigen der neuen Komponenten (z. B. CoordinatorLayout) können Sie möglicherweise (!) Das Bildlaufverhalten erzielen.
Ich habe versucht, mit einem eingebauten Scroll-Verhalten, aber nichts funktioniert für mich,
Ich habe eine untere Leiste (LinearLayout) in meinem Layout anstelle von FloatingActionButton
Hier was ich will.
OnLaunch der unteren Leiste dieses Bildschirms sollte erscheinen.Ein Bildlauf in der unteren Leiste von recyclerview sollte nach unten führen.Ein Bildlauf nach unten in der unteren Leiste von recyclerview sollte einen Bildlauf nach oben durchführen.ibt es einen eingebauten Mechanismus, um dies zu erreichen? oder müssen wir java code schreiben?
Hier ist mein Code:
