RecyclerView中类似寻呼机的行为 [英] Pager-like behavior in RecyclerView
问题描述
我正在尝试为水平RecyclerView实现类似ViewPager的行为.来自适配器的数据应正常进行充气和绑定，但是通过Recycler进行的导航应以不同的方式进行处理.当用户滑动(或尝试滚动)时，我沿该方向移动Recycler一项，并将其粘贴到左侧.
I am trying to implement a ViewPager-like behavior for a horizontal RecyclerView. The data from the adapter should inflate and bind as normal, but the navigation through the Recycler should be handled differently. When the user swipes (or attempts to scroll), I move the Recycler one item in that direction, sticking it to the left side.
我已经拥有所有项目转换逻辑.我使用的是自定义LayoutManager，它会用自定义LinearSmoothScroller()覆盖onSmoothScrollToPosition()，该自定义LinearSmoothScroller()会将项目粘贴到左侧.
I already have all the item transition logic. I am using a custom LayoutManager, which overrides onSmoothScrollToPosition() with a custom LinearSmoothScroller() which does the item to-the-left sticking.
问题是-如何覆盖RecyclerView的滚动行为以拦截刷卡并自己处理?我尝试禁用LayoutManager中的滚动，然后在onTouchListener中拦截手势，但这似乎不起作用. RecyclerView框架是否有解决此问题的干净方法?
The question is - how can I override the scrolling behavior of the RecyclerView to intercept the swipes and handle them myself? I tried disabling scrolling in the LayoutManager and then intercepting the gesture in an onTouchListener, but this does not seem to work. Does the RecyclerView framework have a clean way to handle this?
推荐答案
这是使RecyclerView表现得像ViewPager一样简单的方法.
The native Android solution covered in this post was a super easy way to get the RecyclerView to behave like a ViewPager.

24.2.0版的支持库引入了两个新类(SnapHelper和LinearSnapHelper)，这些类应用于处理RecyclerView中的捕捉. .... 唯一需要的代码是:
The 24.2.0 version of the support library introduced two new classes (SnapHelper and LinearSnapHelper) that should be used to handle snapping in a RecyclerView. .... The only code needed is:
SnapHelper snapHelper = new LinearSnapHelper();
snapHelper.attachToRecyclerView(recyclerView);
SnapHelper snapHelper = new LinearSnapHelper();
snapHelper.attachToRecyclerView(recyclerView);
SnapHelper snapHelper = new GravitySnapHelper(Gravity.START);
snapHelper.attachToRecyclerView(startRecyclerView);
SnapHelper snapHelper = new GravitySnapHelper(Gravity.START);
snapHelper.attachToRecyclerView(startRecyclerView);
