带页眉和页脚的Recyclerview

Question

enter image description here部门数量 name1 1 10.00在此处输入图片描述 名称2 2 10.00 名称3 3 50.00

总计6 70.00

部门数量 名称4 2 10.00 名称5 5 20.00 名称6 4 30.00

总计11 60.00

我在API 1（名称1到名称3）和API2（名称4到名称6）中都具有api数据，但我曾尝试过，但标头将从正常项目移至0位置并出现在项目单元格中

任何人都可以帮助我获得页眉，页脚获得recyclerview吗？

部分标题视图

公共类CallDetailsAdapter扩展了RecyclerView.Adapter {

private List<Object> mList;
private Context mContext;
private static final int ITEM_TYPE_NORMAL = 0;
private static final int ITEM_TYPE_HEADER = 1;

private ArrayList<String> displayedTicketList;
private Fragment fragment;

@Override

    } else if (viewType == ITEM_TYPE_NORMAL) {
        viewHolder = new DashboardViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.raw_sales_summary_list, parent, false));
    }
    return viewHolder;
}

@Override

    switch (holder.getItemViewType()) {
        case ITEM_TYPE_HEADER:

            break;
    }
}

}

@Override

    if (isPositionHeader(position))
        return ITEM_TYPE_HEADER;
    return ITEM_TYPE_NORMAL;
}

    return position == 0;
}

private interface ItemClickListener {
    void onItemClicked(int position);
}

        ButterKnife.bind(this, view);

    @Override
