我使用ViewPager2与碎片,注意到在像小米、裕龙、华硕、vivo等运行Android 8或9的设备上出现两个相关的IllegalStateExceptions(我自己无法复制):
Fatal Exception: java.lang.IllegalStateException: Page can only be offset by a positive amount, not by -758

和
Fatal Exception: java.lang.IllegalStateException: Page(s) contain a ViewGroup with a LayoutTransition (or animateLayoutChanges="true"), which interferes with the scrolling animation. Make sure to call getLayoutTransition().setAnimateParentHierarchy(false) on all ViewGroups with a LayoutTransition before an animation is started.

在浏览时,我经过了以下线程:https://issuetracker.google.com/issues/129530305,根据我的理解,似乎总结为在viewPager2的任何父布局上将animateLayoutChanges
设置为false,这就是我所做的。不幸的是,那并没有解决我的问题。然后我发现了另一个线程:java.lang.IllegalStateException: Page can only be offset by a positive amount,它似乎没有太大帮助。有什么想法可能会导致这个问题?
