使用Gridlayout Manager的Recycler视图

Question

我正在RecyclerView和GridLayout经理一起使用,以便像旅行一样预订座位.

我的问题是当我的列是随机的时候如何自动检测spancount？

我知道spanCount = recyclerViewWidth / singleItemWidth;,但问题是singleItemWidth不同的,因为座位宽度不同.

这是我想要的所需布局:

...但我现在得到这样的东西:

这是我用来安排座位布局的代码:

    gridLayoutManager=new GridLayoutManager(this,totalRows, LinearLayoutManager.VERTICAL,
            false);
    gridLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
        @Override
        public int getSpanSize(int position) {
            int rows=Integer.parseInt(upperlist.get(position).get("row"));
             return (rows);///(int) (mRecyclerView.getMeasuredWidth()/ 10);
        }
    });
     mRecyclerView.setLayoutManager( gridLayoutManager);
    MyAdapter myAdapter=new MyAdapter(this,gridArray);

... upperlist保持这些值:

 [{cols=8, seatNumber=29U, row=4, zindex=1}, 
  {cols=6,seatNumber=23U, row=4, zindex=1},
  {cols=4,seatNumber=21U,row=4, zindex=1}, 
  {cols=2, seatNumber=11U, row=4, zindex=1}, 
  {cols=0,seatNumber=9U,row=4, zindex=1},

  {cols=8,seatNumber=25U, row=2, zindex=1}, 
  {cols=6,seatNumber=17U, row=2, zindex=1}, 
  {cols=4,seatNumber=13U, row=2, zindex=1}, 
  {cols=2,seatNumber=5U,  row=2, zindex=1}, 
  {cols=10, seatNumber=D2U,row=2, zindex=1}, 
  {cols=0, seatNumber=1U, row=2, zindex=1}, 

  {cols=8, seatNumber=26U, row=1, zindex=1},
  {cols=6,seatNumber=18U, row=1, zindex=1}, 
  {cols=4,seatNumber=14U, row=1, zindex=1},
  {cols=2,seatNumber=6U,  row=1, zindex=1}, 
  {cols=0,seatNumber=2U,  row=1, zindex=1}]

这是一个单独的列表,我对行和列有不同的值.因此,我需要一种可以适用于所有布局的通用方法.
