RecyclerView 的每个Item的点击事件并没有像 ListView 一样封装在组件中，需要 Item 的单击事件时就需要自己去实现，在 Adapter 中为RecyclerView 添加单击事件参考如下：

RecyclerView的使用方法请参考：RecyclerView的简单使用

第一步：

在 RecyclerView 的 Adapyer 中定义单击事件的回调接口：

/*** 定义 RecyclerView 选项单击事件的回调接口*/
public interface OnItemClickListener{//参数（父组件，当前单击的View,单击的View的位置，数据）void onItemClick(RecyclerView parent,View view, int position, String data);
}

第二步：

在RecyclerView的Adapyer中声明该接口，并提供setter方法：

private OnItemClickListener onItemClickListener;
public void setOnItemClickListener(OnItemClickListener onItemClickListener){this.onItemClickListener = onItemClickListener;
}

第三步：

在RecyclerView的Adapyer类实现View.OnClickListener接口，并重写onClick(View view)方法，然后设置给接口的事件监听：

public class RvAdapter1 extends RecyclerView.Adapter<RvAdapter1.DataViewHolder> implements View.OnClickListener{...view.setOnClickListener(this);//设置监听器...@Overridepublic void onClick(View view) {//根据RecyclerView获得当前View的位置int position = recyclerView.getChildAdapterPosition(view);//程序执行到此，会去执行具体实现的onItemClick()方法if (onItemClickListener!=null){onItemClickListener.onItemClick(recyclerView,view,position,mList.get(position));}}...
}

第四步：

在MainActivity中通过Adapter设置每个Item的单击事件：

adapter.setOnItemClickListener(new RvAdapter1.OnItemClickListener() {@Overridepublic void onItemClick(RecyclerView parent, View view, int position, String data) {Toast.makeText(MainActivity.this, data, Toast.LENGTH_SHORT).show();}
});

参考代码

Adapter

/*** Created by jzman on 2017/5/13 0013.* RecycleView的Adapter*/
public class RvAdapter1 extends RecyclerView.Adapter<RvAdapter1.DataViewHolder> implements View.OnClickListener{private Context mContext;private RecyclerView recyclerView;private ArrayList<String> mList;public RvAdapter1() {}public RvAdapter1(Context mContext, ArrayList<String> mList) {this.mContext = mContext;this.mList = mList;}/*** 用于创建ViewHolder* @param parent* @param viewType* @return*/@Overridepublic DataViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {View view = LayoutInflater.from(mContext).inflate(R.layout.item,null);view.setOnClickListener(this);//使用代码设置宽高（xml布局设置无效时）view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT));DataViewHolder holder = new DataViewHolder(view);return holder;}/*** 绑定数据* @param holder* @param position*/@Overridepublic void onBindViewHolder(DataViewHolder holder, int position) {holder.tv_data.setText(mList.get(position));}/*** 选项总数* @return*/@Overridepublic int getItemCount() {return mList.size();}@Overridepublic void onClick(View view) {//根据RecyclerView获得当前View的位置int position = recyclerView.getChildAdapterPosition(view);//程序执行到此，会去执行具体实现的onItemClick()方法if (onItemClickListener!=null){onItemClickListener.onItemClick(recyclerView,view,position,mList.get(position));}}/*** 创建ViewHolder*/public static class DataViewHolder extends RecyclerView.ViewHolder{TextView tv_data;public DataViewHolder(View itemView) {super(itemView);tv_data = (TextView) itemView.findViewById(R.id.tv_recycle);}}private OnItemClickListener onItemClickListener;public void setOnItemClickListener(OnItemClickListener onItemClickListener){this.onItemClickListener = onItemClickListener;}/*** 定义RecyclerView选项单击事件的回调接口*/public interface OnItemClickListener{//参数（父组件，当前单击的View,单击的View的位置，数据）void onItemClick(RecyclerView parent,View view, int position, String data);}/***   将RecycleView附加到Adapter上*/@Overridepublic void onAttachedToRecyclerView(RecyclerView recyclerView) {super.onAttachedToRecyclerView(recyclerView);this.recyclerView= recyclerView;}/***   将RecycleView从Adapter解除*/@Overridepublic void onDetachedFromRecyclerView(RecyclerView recyclerView) {super.onDetachedFromRecyclerView(recyclerView);this.recyclerView = null;}
}

MainActivity

/*** Created by jzman on 2017/5/13 0013.*/
public class MainActivity extends AppCompatActivity {private RecyclerView rv;RvAdapter1 adapter;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);rv = (RecyclerView) findViewById(R.id.rv);//设置布局管理器
//        rv.setLayoutManager(new LinearLayoutManager(this));//线性rv.setLayoutManager(new GridLayoutManager(this,4));//线性
//        rv.setLayoutManager(new StaggeredGridLayoutManager(4,StaggeredGridLayoutManager.VERTICAL));//线性adapter = new RvAdapter1(this,initData());adapter.setOnItemClickListener(new RvAdapter1.OnItemClickListener() {@Overridepublic void onItemClick(RecyclerView parent, View view, int position, String data) {Toast.makeText(MainActivity.this, data, Toast.LENGTH_SHORT).show();}});rv.setAdapter(adapter);}public static ArrayList<String> initData(){ArrayList<String> arrayList = new ArrayList<>();for (int i=0;i<50;i++){arrayList.add("第"+i+"条数据");}return arrayList;}
}
