佈局管理器顯示不同跨度：

實用RecyclerView必須設定一個佈局管理器，這裡設定GridLayoutManager,還需要給佈局管理器設定一個方法；

 //設定表格，根據position計算在該position處item的跨度(佔幾列資料)
        layoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
            @Override
            public int getSpanSize(int position) {
                //計算在哪個position更換跨度，要佔滿一行跨度就是2
                if (position < type1Names.length)
                    return 2;
                else //不需要佔滿一行跨度就是1
                    return 1;
            }
        });
