Question

我有一个场景，我需要创建一个包含3个部分的RecyclerView 名为“First”的第一部分应显示3行，每行包含TextView和EditText
名为“Second”的第二部分应包含2行，每行显示单个TextView

名为“Third”的第三部分应包含4行，每行显示带有图像
的TextView。有没有办法可以使用RecyclerView实现这一目标？
任何人都可以共享链接或示例代码片段以实现此功能

先谢谢

您可以使用库SectionedRecyclerViewAdapter将数据分组到各个部分。

首先创建一个Section类：

class MyFirstSection extends StatelessSection {

    String title;
    List<String> list;

    public MyFirstSection(String title, List<String> list) {
        // call constructor with layout resources for this Section header, footer and items 
        super(R.layout.section_header, R.layout.section_item);

        this.title = title;
        this.list = list;
    }

    @Override
    public int getContentItemsTotal() {
        return list.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(list.get(position));
    }

    @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(title);
    }
}

然后使用您的章节设置RecyclerView：

// Create an instance of SectionedRecyclerViewAdapter 
SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();

// Create your sections with the list of data for each year
MyFirstSection section1 = new MyFirstSection("First", firstDataList);
MySecondSection section2 = new MySecondSection("Second", secondDataList);
MyThirdSection section3 = new MyThirdSection("Third", thirdDataList);

// Add your Sections to the adapter
sectionAdapter.addSection(section1);
sectionAdapter.addSection(section2);
sectionAdapter.addSection(section3);

// Set up your RecyclerView with the SectionedRecyclerViewAdapter
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(sectionAdapter);

具有不同布局的分段RecyclerView
