RecyclerView多布局的简单使用demo

很久没有写博客了，最近在写一个比较复杂的项目，里面有很多的recyclerView多布局，正好也借此写一个比较简单的的多布局的demo.以供大家进行参考（虽然网上太多这样的文章）。
不多说了首先先准备主页面布局和两个多布局

"http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.cnd.rvmorelayout.MainActivity">

    .support.v7.widget.RecyclerView
        android:id="@+id/rv_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

item1布局

 id="@+id/tv_item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="你不知道的事" />

item2布局

    <TextView
        android:id="@+id/tv_item2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="雪一片一片一片一片" />

    <ImageView
        android:layout_width="10dp"
        android:layout_height="10dp"
        android:layout_toRightOf="@+id/tv_item2"
        android:layout_marginLeft="5dp"
        android:background="@mipmap/ic_launcher" />

MainActivity

public class MainActivity extends AppCompatActivity {
    private RecyclerView mRv;
    private Context mContext;
    private List datas = new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
    }

    private void initView() {
        mContext = this;
        mRv = findViewById(R.id.rv_main);
        LoadData();
        final LinearLayoutManager manager = new LinearLayoutManager(mContext);
        manager.setOrientation(LinearLayoutManager.VERTICAL);
        mRv.setLayoutManager(manager);
        final MyAdapter myAdapter = new MyAdapter(datas);
        mRv.setAdapter(myAdapter);

    }

    private void LoadData() {
        for (int i = 0; i < 10; i++) {
            datas.add("你是我心内的一首歌" + i);
        }
    }
}

适配器

public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private static final int NORMAL_TYPE = 0;
    private static final int CHECK_TYPE = 1;

    @Override
    public int getItemViewType(int position) {
        if (position == 0) {
            return CHECK_TYPE;
        }
        return NORMAL_TYPE;
    }

    private List datas;

    public MyAdapter(List datas) {
        this.datas = datas;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        if (viewType == NORMAL_TYPE) {
            return new NormalHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false));
        } else
            return new CheckHoldr(LayoutInflater.from(parent.getContext()).inflate(R.layout.item2, parent, false));
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        if (holder instanceof NormalHolder) {
            ((NormalHolder) holder).tv_name.setText(datas.get(position -1));
        } else {
            ((CheckHoldr) holder).tv_name2.setText("我是头部哦");
        }
    }

    @Override
    public int getItemCount() {
        return datas.size()+1;
    }

    class NormalHolder extends RecyclerView.ViewHolder {

        TextView tv_name;

        public NormalHolder(View itemView) {
            super(itemView);
            tv_name = (TextView) itemView.findViewById(R.id.tv_item);

        }

    }

    class CheckHoldr extends RecyclerView.ViewHolder {
        TextView tv_name2;

        public CheckHoldr(View itemView) {
            super(itemView);
            tv_name2 = itemView.findViewById(R.id.tv_item2);
        }
    }

}

注意下数据的数目的变化，以防止在项目中缺少头部的第一条数据。
