2.1MainActivity中：

<span style="font-size:18px;">public class MainActivity extends Activity {    //    private RecyclerView mRecyclerView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);//      初始化RecyclerView        mRecyclerView = (RecyclerView) findViewById(R.id.id_recyclerview);//      RecyclerView设置展示的的样式（listView样子，gridView样子，瀑布流样子）//        listView纵向滑动样子        LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);        mRecyclerView.setLayoutManager(linearLayoutManager);//      获取数据，向适配器传数据，绑定适配器        ArrayList<String> datas = initData();        HomeAdapter honmeAdapter = new HomeAdapter(MainActivity.this,datas);        mRecyclerView.setAdapter(honmeAdapter);//      调用按钮返回事件回调的方法        honmeAdapter.buttonSetOnclick(new HomeAdapter.ButtonInterface() {            @Override            public void onclick(View view, int position) {                Toast.makeText(MainActivity.this, "点击条目上的按钮"+position, Toast.LENGTH_SHORT).show();            }        });    }    /**     * 编写一套假数据     */    protected ArrayList<String> initData() {        ArrayList<String> mDatas = new ArrayList<String>();        for (int i = 0; i < 100; i++) {            mDatas.add("我是条目" + i);        }        return  mDatas;    }}</span>

2.2布局文件：activity_main.xml

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    >    <android.support.v7.widget.RecyclerView        android:id="@+id/id_recyclerview"        android:layout_width="match_parent"        android:layout_height="match_parent" >    </android.support.v7.widget.RecyclerView></LinearLayout></span>
2.3条目的布局文件：item_home.xml

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:background="#44ff0000"    android:layout_height="wrap_content"    android:orientation="vertical"    ><LinearLayout    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:orientation="horizontal"    >    <TextView        android:id="@+id/id_num"        android:layout_width="0dp"        android:layout_height="50dp"        android:gravity="center"        android:layout_weight="1"        />    <Button        android:id="@+id/id_button"        android:layout_width="0dp"        android:layout_height="wrap_content"        android:text="按钮"        android:layout_weight="1"        /></LinearLayout>    <TextView        android:layout_width="match_parent"        android:layout_height="2dp"        android:background="#000033"        /></LinearLayout></span>
3适配器中HomeAdapter

<span style="font-size:18px;">class HomeAdapter extends RecyclerView.Adapter<HomeAdapter.MyViewHolder> {    private Context context;    private ArrayList<String> list;    private ButtonInterface buttonInterface;    public HomeAdapter(Context context, ArrayList<String> list) {        this.context = context;        this.list = list;    }    /**     *按钮点击事件需要的方法     */    public void buttonSetOnclick(ButtonInterface buttonInterface){        this.buttonInterface=buttonInterface;    }    /**     * 按钮点击事件对应的接口     */    public interface ButtonInterface{        public void onclick( View view,int position);    }    @Override    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        MyViewHolder holder = new MyViewHolder(LayoutInflater.from(                context).inflate(R.layout.item_home, parent,                false));        return holder;    }    @Override    public void onBindViewHolder(MyViewHolder holder, final int position) {        holder.tv.setText(list.get(position));        holder.id_button.setText(list.get(position));        holder.id_button.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if(buttonInterface!=null) {//                  接口实例化后的而对象，调用重写后的方法                    buttonInterface.onclick(v,position);                }            }        });    }    @Override    public int getItemCount() {        return list.size();    }    /**     * ViewHolder的类，用于缓存控件     */    class MyViewHolder extends RecyclerView.ViewHolder {        TextView tv;        Button id_button;        public MyViewHolder(View itemView) {            super(itemView);            tv = (TextView) itemView.findViewById(R.id.id_num);            id_button = (Button) itemView.findViewById(R.id.id_button);        }    }}</span>
