RecyclerView recyclerView = findViewById(R.id.recycler_view);
      DWStickItemDecoration decoration = new DWStickItemDecoration(this) {
                @Override
                protected boolean isShowItemLabel(int position) {
                    //返回true表示要显示组的第一个item的标签
                    //看下面的模拟演示数据
                    return mList.get(position).isShowLable();
                }

@Override
                protected String getItemLabelStr(int position) {
                    //返回标签的文本字符串
                    return mList.get(position).getSpell();
                }
