Sync scrolling of multiple RecyclerViews

by

Here was my solution. The less the code the better…

lvDetail & lvDetail2 are the RecyclerViews you want to keep in sync.

    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, int dx, int dy)
        {
            super.onScrolled(recyclerView, dx, dy);
            lvDetail.removeOnScrollListener(scrollListeners[0]);
            lvDetail.scrollBy(dx, dy);
            lvDetail.addOnScrollListener(scrollListeners[0]);
        }
    };
    lvDetail.addOnScrollListener(scrollListeners[0]);
    lvDetail2.addOnScrollListener(scrollListeners[1]);
