Interessante Beobachtung. Wenn ich meine Recyclerview nach unten scrolle, scrollen Sie auf Programmebene wirklich! Ursache, wenn ich auf Element tippe - es zeigt (in einem anderen Fragment) Element, das am Ende der Liste steht! Und wenn ich "zurück" drücke, bin es mich zurück zum gescrollten Recyclerview !!! Ich denke, es bedeutet, dass das Problem in der Nähe des Layout -Managers und konkret in Element Decorator oder Element Animator liegt. Zum Beispiel: < /p>
import com.google.android.collect.Lists;
import android.util.MathUtils;
import android.view.ViewRootImpl;
< /code>
...und viele andere in anderen *.java -Dateien.
Kann es mit der Verlust der Funktionalität dieser Komponenten verbunden werden? Und wie kann ich dieses Problem beheben? Hilf mir bitte.
