RecyclerView的多item布局实现_recyclerview不同item

![在类似这样的。开始撸代码。
1.MainActivity 类对象

public class MainActivity extends AppCompatActivity {
   
    
    private ExampleAdapter adapter;
    private List<ExampleBaseBean> mlist = new ArrayList<>();
    private RecyclerView rv;
    private Context context;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
   
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        context = this;
        rv = (RecyclerView)findViewById(R.id.rv);
        initTitle();
        initBody();
        initFoot();
        initAdapter();
    }

    private void initTitle() {
   
        List<String> titles = new ArrayList<>(5);
        for (int i = 0; i < 50; i++) {
   
            titles.add(new StringBuilder("标题").append(i).toString());
        }
        TitleBean titleBean = new TitleBean();
        titleBean.setTitles(titles);
        titleBean.setViewType(ExampleAdapter.TITLE);//设置横向列表的类型
        mlist.add(titleBean);
    }

    //装载轮播图数据源
    private void initBody() {
   
        List<Integer> res = new ArrayList<>(9);
        res.add(R.mipmap.pic1);
        res.add(R.mipmap.pic2);
        res.add(R.mipmap.pic3);
        res.add(R.mipmap.pic4);
        res.add(R.mipmap.pic5);
        res.add(R.mipmap.pic6);
        res.add(R.mipmap.pic7);
        res.add(R.mipmap.pic8);
        res.add(R.mipmap.pic9);
        BodyBean bodyBean = new BodyBean();
        bodyBean.setRes(res);
        bodyBean.setViewType(ExampleAdapter.BODY);//设置横向列表的类型
        mlist.add(bodyBean);
    }

    private void initFoot() {
   
        for (int i = 0; i < 1000; i++) {
   
            FootBean footBean=new FootBean("foot:"+i);
            footBean.setViewType(ExampleAdapter.FOOT);//正常列表
            mlist.add(footBean);
        }
    }

    private void initAdapter() {
   
            adapter = new ExampleAdapter(mlist);
            rv.setLayoutManager(new LinearLayoutManager(context))
