你可以很容易地在ViewHolder类中定义setOnClickListener，如下所示:

public class ViewHolder extends RecyclerView.ViewHolder {
    TextView product_name;

    ViewHolder(View itemView) {
        super(itemView);
        product_name = (TextView) itemView.findViewById(R.id.product_name);
        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int itemPosition = getLayoutPosition();
                Toast.makeText(getApplicationContext(), itemPosition + ":" + String.valueOf(product_name.getText()), Toast.LENGTH_SHORT).show();
            }
        });
    }
}

对我来说，最干净的方法就是这个。

适配器的构造函数

private class EnvironmentTypeRecyclerViewAdapter extends RecyclerView.Adapter<EnvironmentTypeRecyclerViewAdapter.ViewHolder>
{
     private final EnvironmentTypeRecyclerViewAdapterListener mEnvironmentTypeRecyclerViewAdapterListener;
     private List<Environment> mEnvironmentsData;

     public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
     {
         public ViewHolder(View v)
         {
             super(v);
             v.setOnClickListener(this);

         }

         @Override
         public void onClick(View v)
         {
              Environment environment = mEnvironmentsData.get(getAdapterPosition());
              if (mEnvironmentTypeRecyclerViewAdapterListener != null && environment != null) {
                      mEnvironmentTypeRecyclerViewAdapterListener.onListItemSelected(environment);      
              }
        }

        public EnvironmentTypeRecyclerViewAdapter(List<SmallCellEnvironment> environments, EnvironmentTypeRecyclerViewAdapterListener environmentTypeRecyclerViewAdapterListener)
        {
            mEnvironmentTypeRecyclerViewAdapterListener = environmentTypeRecyclerViewAdapterListener;
            mEnvironmentsData = environments;
        }
}

链接接口

private interface EnvironmentTypeRecyclerViewAdapterListener
{
    void onListItemSelected(Environment environment);
}

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) {
        // ...
    }
}));

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

你可以实现View。OnClickListener到你的ViewHolder类

public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        
    public Item item
    @InjectView(R.id.tv_title) 
    public TextView tvTitle;
    @InjectView(R.id.rl_row) 
    public RelativeLayout rlRow;

    public ViewHolder(View v) {
        super(v);
        ButterKnife.inject(this, v);
        v.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        Log.e("item title",item.getTitle());
    }
}

和onBindViewHolder设置你的视图持有人的项目:

public void onBindViewHolder(ViewHolder holder, int position) {
    holder.tvTitle.setText(objects.get(position).getTitle());
    holder.item = objects.get(position);
}

这就是重用View的方法。OnClickListener:

public class TestAdapter extends RecyclerView.Adapter<TestAdapter.MyviewHolder>
    implements View.OnClickListener

在ViewHoder中获取项目布局的父视图:

public class MyviewHolder extends RecyclerView.ViewHolder {

    LinearLayout linearLayout;

    public MyviewHolder(View itemView) {
        super(itemView);
        linearLayout = itemView.findViewById(R.id.linear_layout_item);
    }
}

在onBindViewHolder中设置标签为位置:

@Override
public void onBindViewHolder(MyviewHolder holder, int position) {
    holder.linearLayout.setTag(position);
    holder.linearLayout.setOnClickListener(this);
}

在你的onClick实现中:

@Override
public void onClick(View v) {
    int position = (int) v.getTag();

    switch (v.getId()) {
        case R.id.linear_layout_item:
            // do some thing with position 
            break;
    }
}
