我在我的Android应用程序中使用了RecyclerView。我的RecyclerView中有许多cardview，因此一次只向用户显示1个cardview。用户必须滑动才能看到下一张卡。

我遇到了一个问题，当用户滑动时，回收视图会滚动到最后。相反，我需要的是当用户滑动时，向用户显示下一张卡片，如本文所述。

如何在水平回收视图上滑动仅将下一个项目带入视图-Android

SnapHelper snapHelper = new PagerSnapHelper();
snapHelper.attachToRecyclerView(recyclerView);

我尝试了上面链接中提到的答案。但是当用户滑动时，我遇到了异常。

请帮我解决它。

错误

java.lang.IllegalStateException: An instance of OnFlingListener already set.
