在Recyclerview或Listview中添加多个标题.随机

概述如何在RecyclerView或listview中添加多个标题或分隔符.随机突出显示在下图中： RecyclerView中基于日期的多个标题 – 演示图像 您可以使用库 SectionedRecyclerViewAdapter来实现它.它具有“部分”的概念,每个部分都可以有自己的标题. 在我看来,您需要按“日期”对呼叫进行分组.所以你可以像这样创建你的Section类： class MySecti 如何在RecyclerVIEw或ListvIEw中添加多个标题或分隔符.随机突出显示在下图中：

RecyclerVIEw中基于日期的多个标题 – 演示图像

解决方法 您可以使用库 SectionedRecyclerViewAdapter来实现它.它具有“部分”的概念,每个部分都可以有自己的标题.

在我看来,您需要按“日期”对呼叫进行分组.所以你可以像这样创建你的Section类：

class MySection extends StatelessSection {    String date;    List<Call> callList;    public MySection(String date,List<Call> callList) {        // call constructor with layout resources for this Section header,footer and items         super(R.layout.section_header,R.layout.section_footer,R.layout.section_item);        this.date = date;        this.callList = callList;    }    @OverrIDe    public int getContentItemsTotal() {        return callList.size(); // number of items of this section    }    @OverrIDe    public RecyclerVIEw.VIEwHolder getItemVIEwHolder(VIEw vIEw) {        // return a custom instance of VIEwHolder for the items of this section        return new MyItemVIEwHolder(vIEw);    }    @OverrIDe    public voID onBindItemVIEwHolder(RecyclerVIEw.VIEwHolder holder,int position) {        MyItemVIEwHolder itemHolder = (MyItemVIEwHolder) holder;        // bind your vIEw here        itemHolder.tvItem.setText(callList.get(position).getContactname());    }    @OverrIDe    public RecyclerVIEw.VIEwHolder getheaderVIEwHolder(VIEw vIEw) {        return new SimpleheaderVIEwHolder(vIEw);    }    @OverrIDe    public voID onBindheaderVIEwHolder(RecyclerVIEw.VIEwHolder holder) {        MyheaderVIEwHolder headerHolder = (MyheaderVIEwHolder) holder;        // bind your header vIEw here        headerHolder.tvItem.setText(date);    }}

然后使用您的章节设置RecyclerVIEw：

// Create an instance of SectionedRecyclerVIEwAdapter SectionedRecyclerVIEwAdapter sectionAdapter = new SectionedRecyclerVIEwAdapter();MySection mySection1 = new MySection("27 Mar,2016",callList1);MySection mySection2 = new MySection("28 Mar,callList2);// Add your SectionssectionAdapter.addSection(mySection1);sectionAdapter.addSection(mySection2);// Set up your RecyclerVIEw with the SectionedRecyclerVIEwAdapterRecyclerVIEw recyclerVIEw = (RecyclerVIEw) findVIEwByID(R.ID.recyclervIEw);recyclerVIEw.setLayoutManager(new linearlayoutmanager(getContext()));recyclerVIEw.setAdapter(sectionAdapter);
