我们可以使用Java弱引用来实现这一点。 从语义上讲，视图持有者应该响应click事件或将其委托给正确的响应器。

我们的目标:

Viewholder应该对响应事件的类一无所知，除非它实现了某个接口。 点击处理程序应该得到被点击的视图在RecyclerView中的位置。 我们应该能够辨别视图持有人中单击了哪个视图。 保持所有组件之间的松散耦合，不要造成任何保留周期。

步骤:

Create an interface to handle click responses. Implement this interface in the Activity that will handle the click. Add a member variable in the RecyclerView Adapter to hold the Weak Reference and a constructor that sets it. Do the same in the RecyclerView ViewHolder and add a member variable to keep track of position. Set your on click listeners on any view you'd like in the ViewHolder, then callback to the responder to handle them. Change your onBindViewHolder method to set the position when binding. Pass the responder down to the ViewHolder. In the responder, you can now use getId() on the view to figure out which view was clicked.

这里是一个要点，这样你就可以看到它们是如何组合在一起的: RecyclerView点击处理

基于Jacob Tabak的回答(+1)，我能够添加onLongClick监听器:

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
    public interface OnItemClickListener {
        void onItemClick(View view, int position);

        void onItemLongClick(View view, int position);
    }

    private OnItemClickListener mListener;

    private GestureDetector mGestureDetector;

    public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) {
        mListener = listener;

        mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override
            public void onLongPress(MotionEvent e) {
                View childView = recyclerView.findChildViewUnder(e.getX(), e.getY());

                if (childView != null && mListener != null) {
                    mListener.onItemLongClick(childView, recyclerView.getChildAdapterPosition(childView));
                }
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
        View childView = view.findChildViewUnder(e.getX(), e.getY());

        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
        }

        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
    }
}

然后你可以这样使用它:

recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(getActivity(), recyclerView, new RecyclerItemClickListener.OnItemClickListener() {
    @Override
    public void onItemClick(View view, int position) {
        // ...
    }

    @Override
    public void onItemLongClick(View view, int position) {
        // ...
    }
}));

这对我来说很难在活动中有一个项目点击监听器，也有一个项目的单一视图的点击监听器，不会触发项目点击监听器。在玩了Jacob Tabak的回答后，我尊重他的回答，如果项目内没有其他触摸操作，就点击项目。

我有一个自定义OnClickListener接口，有一个项目点击事件，它持有从适配器点击的项目的视图和项目的位置。我在构造函数(或者它可以是setter)中呈现它的一个实例，并将它附加到视图持有者容器click listener。

我也有其他的点击监听器在适配器(可以在视图持有人)，这将处理当前的视图点击从容器。

 public class MyRecyclerAdapter extends RecyclerView.Adapter<MyViewHolder> {

private ArrayList<String> mData;
private OnItemClickListener mOnItemClickListener;

public interface OnItemClickListener {
    public void onItemClick(View view, int position);
}

public MyRecyclerAdapter(ArrayList<String> itemsData,
        OnItemClickListener onItemClickListener) {
    mOnItemClickListener = onItemClickListener;
    this.mData = itemsData;
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent,
        int viewType) {

    View layoutView = LayoutInflater.from(mContext).inflate(
            R.layout.list_item, parent, false);

    final MyViewHolder viewHolder = new MyViewHolder(layoutView);

    viewHolder.container.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            mOnItemClickListener.onItemClick(v, viewHolder.getAdapterPosition());
        }
    });

    viewHоlder.button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            //do button click work here with
            // mData.get( viewHolder.getAdapterPosition() );
        }
    });

    return viewHolder;
}

@Override
public int getItemCount() {
    return mData.size();
}}

在活动中，您需要通过传递OnItemClickListener实例来初始化适配器

public class FeedActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    ...

    RecyclerView recyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);

    .....

    MyRecyclerAdapter adapter = new MyRecyclerAdapter(new ArrayList<String>(), new OnItemClickListener() {

        @Override
        public void onItemClick(View view, int position) {

            ///list item was clicked
        }
    });

    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    recyclerView.setAdapter(mFeedsAdapter);
}

还有我的ViewHolder

public class MyViewHolder extends RecyclerView.ViewHolder {

public Button button;
public View container;

public MyViewHolder(View itemLayoutView) {
    super(itemLayoutView);

    container = itemLayoutView;
    button = (Button) itemLayoutView.findViewById(R.id.button);
}}

通常你在CardView中有多个元素，所以你需要一个布局视图来包装和组织它们。你可以添加一个OnClickListener到那个布局视图。1. 添加一个id到你的布局。在这个例子中是线性布局

<android.support.v7.widget.CardView
 .....>

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/card_view_linearLayout">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="name"
            android:id="@+id/card_view_name" />

        ...

    </LinearLayout>

</android.support.v7.widget.CardView>

2美元。在你的内部ViewHolder类中获取布局视图。

public static class ViewHolder extends RecyclerView.ViewHolder{
    private TextView nameView;
    ...
    private LinearLayout linearLayout;
    public ViewHolder(View itemView) {
        super(itemView);
        nameView = (TextView)itemView.findViewById(R.id.card_view_name);
        ...
        linearLayout = (LinearLayout)itemView.findViewById(R.id.card_view_linearLayout);
    }
}

3美元。将监听器添加到onBindViewHolder中的布局中，并使用回调将数据发送到活动或片段(未测试)。

@Override
public void onBindViewHolder(TrackAdapter.ViewHolder holder, final int position) {
    String str = mStringList.get(position);

    holder.nameView.setText(str);
    ...
    holder.linearLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            callback.itemCallback(mStringList.get(position));
        }
    });
}

如何使用回调是另一个故事

这对我来说很管用。将OnClickListener附加到onBindView。我真的不知道这是否会影响性能，但它似乎用很少的代码就能很好地工作。

public void onBindViewHolder(ViewHolder holder, final int position) {
    holder.view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(context, "Recycle Click" + position, Toast.LENGTH_SHORT).show();
            }
    });
}

nhaarman答案的Kotlin实现:

mRecyclerView.addOnItemTouchListener(object  : RecyclerItemClickListener(this, mRecyclerView,object :RecyclerItemClickListener.OnItemClickListener{
            override fun onItemClick(view: View, position: Int) {

            }

            override fun onLongItemClick(view: View?, position: Int) {

            }
}){})

RecyclerItemClickListener.java:

import android.content.Context
import android.support.v7.widget.RecyclerView
import android.view.GestureDetector
import android.view.MotionEvent
import android.view.View


open class RecyclerItemClickListener(context: Context, recyclerView: RecyclerView, private val mListener: OnItemClickListener?) : RecyclerView.OnItemTouchListener {

    private var mGestureDetector: GestureDetector

    interface OnItemClickListener {
        fun onItemClick(view: View, position: Int)

        fun onLongItemClick(view: View?, position: Int)
    }

    init {
        mGestureDetector = GestureDetector(context, object : GestureDetector.SimpleOnGestureListener() {
            override fun onSingleTapUp(e: MotionEvent): Boolean {
                return true
            }

            override fun onLongPress(e: MotionEvent) {
                val child = recyclerView.findChildViewUnder(e.x, e.y)
                if (child != null && mListener != null) {
                    mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child))
                }
            }
        })
    }

    override fun onInterceptTouchEvent(view: RecyclerView, e: MotionEvent): Boolean {
        val childView = view.findChildViewUnder(e.x, e.y)
        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildAdapterPosition(childView))
            return true
        }
        return false
    }

    override fun onTouchEvent(view: RecyclerView, motionEvent: MotionEvent) {}

    override fun onRequestDisallowInterceptTouchEvent(disallowIntercept: Boolean) {}
}
