循环回收器视图 [英] Circular RecyclerView

问题描述

比方说，我们下面是一组视图:

Let's say we the following set of item Views:

View1 -> View2 -> View3 -> ... -> View(n-1) -> View(n)

在经典的RecyclerView上，View1位于第一个位置，View(n)位于最后一个位置.现在，我想做一个圆形，所以在最后一个位置之后，我们再次滚动到第一个位置:

On classic RecyclerView, View1 would be on first position and View(n) on last. Now I would like to make that circular so after last position we scroll again to first position:

View1 -> View2 -> View3 -> ... -> View(n-1) -> View(n) -> View1 -> View2 -> ...

乍看起来，这看起来很简单，但是我不确定在View(n)之后如何完成该重置"操作.任何建议都会非常有帮助.谢谢.

This at first look seems simple to make but I am not sure how to accomplish that "reset" after View(n). Any advice would be really helpful. Thank you.

推荐答案

有关ListView，请参考此解决方案.您可以编写包含Integer.MAX_VALUE个项目的RecyclerView.Adapter.唯一的区别是RecyclerView不再具有setSelectionFromTop方法.相反，您应该致电

Please refer to this solution for ListView. You may write a RecyclerView.Adapter that has Integer.MAX_VALUE items. The only difference is that RecyclerView no longer has setSelectionFromTop method. Instead you should call

recyclerView.getLayoutManager().scrollToPosition(recyclerAdapter.MIDDLE);

首先将recyclerView滚动到中间.

in order to scroll the recyclerView to the middle at first.
