android – 同步滚动多个RecyclerViews

我有一个ViewPager每页显示一个片段.此片段包含RecyclerView中的项目列表.项目列表始终具有相同的大小,并且项目的视图也具有相同的高度.当滚动其中一个RecyclerViews时,我希望其他RecyclerViews同时滚动相同的距离.如何同步RecyclerViews的滚动？

解决方法

这是我的解决方案.代码越少越好……

lvDetail& lvDetail2是您希望保持同步的RecyclerView.

final RecyclerView.OnScrollListener[] scrollListeners = new RecyclerView.OnScrollListener[2];
    scrollListeners[0] = new RecyclerView.OnScrollListener( )
    {
        @Override
        public void onScrolled(RecyclerView recyclerView,int dx,int dy)
        {
            super.onScrolled(recyclerView,dx,dy);
            lvDetail2.removeOnScrollListener(scrollListeners[1]);
            lvDetail2.scrollBy(dx,dy);
            lvDetail2.addOnScrollListener(scrollListeners[1]);
        }
    };
    scrollListeners[1] = new RecyclerView.OnScrollListener( )
    {
        @Override
        public void onScrolled(RecyclerView recyclerView,dy);
            lvDetail.removeOnScrollListener(scrollListeners[0]);
            lvDetail.scrollBy(dx,dy);
            lvDetail.addOnScrollListener(scrollListeners[0]);
        }
    };
    lvDetail.addOnScrollListener(scrollListeners[0]);
    lvDetail2.addOnScrollListener(scrollListeners[1]);
