我已经看了所有的答案，并不是很满意。我找到了更简单快捷的方法。想分享给未来的读者。

选择单个回收项目中的任何视图。 获取这个View的父视图(确保你施放了合适的ViewGroup) 将onClickListener设置为这个父节点。

示例代码(它是在适配器的onBindViewHolder方法中编写的):

@Override
public void onBindViewHolder(@NonNull final ViewHolder holder, final int position) {

    ConstraintLayout parent = (ConstraintLayout) holder.title.getParent();
    parent.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(context, "Clicked recycler view item at position " + position, Toast.LENGTH_SHORT).show();
        }
    });
}

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
            }
        });
        ...
    }
...
}

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;
    }
}

到目前为止，所有的答案都是很好的解决方案，但是如果你不想处理太多的实现细节，只是想让它类似于ListView的工作方式，我建议使用twway - view，如下所示:

https://github.com/lucasr/twoway-view

请注意，这个实现还支持长按项目，以及支持按下状态(这是这个问题的其他解决方案所缺乏的重要内容)。

如果您不想使用整个库，请查看ClickItemTouchListener类，如果需要，可以将其作为独立的类使用。我发现它目前唯一的问题是长按+滚动，它似乎有不正确的行为。

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
        }
    })
)

这是我的自定义适配器的完整代码，这段代码将用XML文件“list_item”中定义的列表项膨胀行，它还将在具有各自位置的所有列表项行上执行单击事件。

public class MyCustomAdapter extends RecyclerView.Adapter`<`AdapterMyCustomAdapter.ViewHolder> {

    public static class ViewHolder extends RecyclerView.ViewHolder implements OnClickListener {
        public onItemClickListener mListener;
        public ViewHolder(View v, onItemClickListener listener) {
            super(v);
            mListener =listener;
            v.setOnClickListener(this);
        }

        @Override
        public void onClick(View v) {
            mListener.onRecyclerItemClick(v, getPosition());
        }

        public static interface onItemClickListener {
            public void onRecyclerItemClick(View view , int position);
        }
    }

    @Override
    public int getItemCount() {
        return 5;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int pos) {      

    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int position) {
        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.list_item, parent, false);

    /* here list_item is an xml file we want to inflate ...it is same as we do in case of listview for customization.*/

        MyCustomAdapter.ViewHolder vh = new ViewHolder(v, new MyCustomAdapter.ViewHolder.onItemClickListener() {

            @Override
            public void onRecyclerItemClick(View view, int position) {
                System.out.println("clicked on list item at position " +position);
            } 
        });
        return vh;
    }
}
