以下是我所做的。这个解决方案同时支持onClick和onLongClick在两个RecyclerView项目和视图内的RecyclerView项目(内部视图)。

我在我选择的视图上标记viewHolder:

public RecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_item, null);
    ViewHolder viewHolder = new ViewHolder(itemView);

    itemView.setOnClickListener( this);
    itemView.setOnLongClickListener(this);
    viewHolder.imageIV.setOnClickListener(this);
    viewHolder.imageIV.setOnLongClickListener(this);

    viewHolder.imageIV.setTag(viewHolder);
    itemView.setTag(viewHolder);

    return viewHolder;
}

我使用holder.getPosition()在onClick()方法中检索位置(onLongClick类似):

public void onClick(View view) {
    ViewHolder holder = (ViewHolder) view.getTag();
    int position = holder.getPosition();

    if (view.getId() == holder.imageIV.getId()){
        Toast.makeText(context, "imageIV onClick at" + position, Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(context, "RecyclerView Item onClick at " + position, Toast.LENGTH_SHORT).show();
    }
}

带有getChildPosition的变体也可以工作。请注意，对于内部视图，在onClick()中使用:

int position = recyclerView.getChildPosition((View)view.getParent());

在我看来，这个解决方案的优点是，当一个人点击图像，只有onclick()图像侦听器被调用，而当我结合Jacob的解决方案为一个RecyclerView项目视图和我的解决方案为内部视图的RecyclerView项目视图onclick()也被调用(当点击图像)。

RecyclerView没有OnClickListener，必须自己实现它。

我喜欢在适配器中添加OnItemClickListener接口，当您从ViewHolder中单击项目视图时调用onClick方法。因此，管理项目点击的职责不在ViewHolder和Adapter的范围内。将决定做什么的活动或片段

为监听器和监听器对象添加接口。

public class ItemsAdapter extends RecyclerView.Adapter<ItemsAdapter.ViewHolder> {

  ...

  private static OnItemClickListener onItemClickListener;

  ...

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

  ...
}

我们捕获项目根视图的单击，以及当回调触发时适配器上的onClick侦听器调用。

public class ItemsAdapter extends RecyclerView.Adapter<ItemsAdapter.ViewHolder> {

  ...

  private static OnItemClickListener onItemClickListener;

  ...

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

  ...

  public static class ViewHolder extends RecyclerView.ViewHolder {
      public ImageView imageView;

      public ViewHolder(View itemRootView) {
          super(itemRootView);
          imageView = (ImageView) itemRootView.findViewById(R.id.itemImage);

          itemRootView.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                  int position  = ViewHolder.super.getAdapterPosition();
                  onItemClickListener.onItemClick(view,position);
              }
          });
      }
  }
}

由于活动或片段，片段在我们的情况下，我们分配一个监听器到适配器和onClick回调，我们将获得选定的项目的位置和打开一个详细的活动项目。

public class ItemsFragment extends Fragment {
    ...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
       ...    
        ((ItemsAdapter) adapter).setOnItemClickListener(new ItemsAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(View view, int position) {
                //Do something when an item has been clicked
            }
        });
        ...
    }
...
}

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();
            }
        });
    }
}

在适配器类中添加接口。

public interface SelectedUser{

    void selectedUser(UserModel userModel);

}

在mainactivity中实现你的接口并覆盖selectedUser方法。

@Override
public void selectedUser(UserModel userModel) {

    startActivity(new Intent(MainActivity.this, SelectedUserActivity.class).putExtra("data",userModel));

}

对于kotlin句柄，根据Jacobs的回答单击RecyclerView答案

创建类RecyclerItemClickListener:

class RecyclerItemClickListener(context: Context, recyclerView: RecyclerView, listner: OnItemClickListener) : RecyclerView.OnItemTouchListener {

    var mGestureDetector: GestureDetector
    var mListner: OnItemClickListener
    
    interface OnItemClickListener {
        fun onItemClick(view: View, position: Int)
        fun onLongItemClick(view: View, position: Int)
    }

    init {
        this.mListner = listner
        mGestureDetector = GestureDetector(context, object : GestureDetector.SimpleOnGestureListener() {
            override fun onSingleTapUp(e: MotionEvent?): Boolean = true
            
            override fun onLongPress(e: MotionEvent?) {
                val child: View? = recyclerView.findChildViewUnder(e!!.getX(), e.getY())
                if (child != null && mListner != null) {
                    mListner.onLongItemClick(child, recyclerView.getChildAdapterPosition(child))
                }
            }
        })
    }

    override fun onTouchEvent(rv: RecyclerView, e: MotionEvent) = Unit

    override fun onInterceptTouchEvent(view: RecyclerView, e: MotionEvent): Boolean {
        val childView: View? = view.findChildViewUnder(e!!.getX(), e.getY())
        if (childView != null && mListner != null && mGestureDetector.onTouchEvent(e)) {
            mListner.onItemClick(childView, view.getChildAdapterPosition(childView))
            return true
        }
        return false
    }

    override fun onRequestDisallowInterceptTouchEvent(disallowIntercept: Boolean) = Unit

}

点击Any RecyclerView(在活动/片段内):

recyclerView.addOnItemTouchListener(
    RecyclerItemClickListener(this, recyclerView, object : RecyclerItemClickListener.OnItemClickListener {
        override fun onItemClick(view: View, position: Int) {
            // TODO catch click
        }

        override fun onLongItemClick(view: View, position: Int) {
            // TODO catch click
        }
    })
)

这里有一个更好的和不那么紧密耦合的方式来实现一个OnClickListener的RecyclerView。

用法片段:

RecyclerView recyclerView = findViewById(R.id.recycler);
recyclerView.addOnItemTouchListener(
    new RecyclerItemClickListener(context, recyclerView ,new RecyclerItemClickListener.OnItemClickListener() {
      @Override public void onItemClick(View view, int position) {
        // do whatever
      }

      @Override public void onLongItemClick(View view, int position) {
        // do whatever
      }
    })
);

RecyclerItemClickListener实现:

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 {
  private OnItemClickListener mListener;

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

    public void onLongItemClick(View view, int position);
  }

  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 child = recyclerView.findChildViewUnder(e.getX(), e.getY());
            if (child != null && mListener != null) {
                mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child));
            }
        }
    });
}

  @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 true;
    }
    return false;
  }

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

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