實(shí)現(xiàn)思路：設(shè)置滑動(dòng)監(jiān)聽(tīng)，滑動(dòng)左邊recycler，右側(cè)recycler跟著移動(dòng)相應(yīng)距離即可(注意：條目高度要相等，如果添加分割線，注意分割線高度)

private void syncScroll(RecyclerView leftList,  RecyclerView rightList) {   
    leftList.addOnScrollListener(new RecyclerView.OnScrollListener() { 
        @Override        
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {            
            if (recyclerView.getScrollState() != RecyclerView.SCROLL_STATE_IDLE) {
                // note: scrollBy() not trigger OnScrollListener 
                // This is a known issue. It is caused by the fact that RecyclerView does not know how LayoutManager will handle the scroll or if it will handle it at all.                           
                rightList.scrollBy(dx, dy);           
            }      
        }   
    });    

    rightList.addOnScrollListener(new RecyclerView.OnScrollListener() {            
         @Override        
         public void onScrolled(RecyclerView recyclerView, int dx, int dy) {              
             if (recyclerView.getScrollState() != RecyclerView.SCROLL_STATE_IDLE) {                
                 leftList.scrollBy(dx, dy);            
             }        
         }    
     });
}
