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);
}

这就是我最后需要的东西，以防有人发现它有用:

public static class ViewHolder extends RecyclerView.ViewHolder {

    public ViewHolder(View item) {

        super(item);
        item.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("RecyclerView", "onClick：" + getAdapterPosition());
            }
        });

    }
}

From most of the answers above, they seem to be setting their onclicklisteners to individual items. However, the solution am about to offer is very simple but yet not intuitive to many. Many are forgetting that the other components are always in a parent component which is used to display items in the List or Recycler views. This solution is just about setting a single onclick listener to this parent view and the turn is played. The solution also includes a way to pass the position of the item being clicked on from the list or recycler view. Here, our main rootview is a CardView from the android support library. Here is sample code

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

public static final String LOG_TAG = ListAdapter.class.getSimpleName();
private Cursor mDataset;
private Context mContext;
private ViewHolder mViewHolder;

// Provide a suitable constructor (depends on the kind of dataset)
public ListAdapter(Context context, Cursor Dataset) {
    mDataset = Dataset;
    mContext = context;
}

// Create new views (invoked by the layout manager)
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    // create a new view
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.list_business_view, parent, false);

    mViewHolder = new ViewHolder(v);
    return mViewHolder;
}

public void setData(Cursor newdata) {
    this.mDataset = newdata;
}

// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
//Bind data to other items here. To save time, i have ommited that.
           //here is where we attach a click listerner for an item in the recycler list rather than for each element of a given item.
            holder.card.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(mContext, " Just cliked item at position " + itemPosition, Toast.LENGTH_LONG).show();

            }
        });

    }
}

// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
    if (null != mDataset) {
        return mDataset.getCount();
    }
    return 0;

}


// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public static class ViewHolder extends RecyclerView.ViewHolder{
    // each data item is just a string in this case
    public final TextView mBusinesssName; // View for the business name
    public final TextView mBusinessCategory; //View for the category name
    public final ImageView businessImage; // View for the business category image Image
    public final TextView mBusinessDistance; // View for the distance
    public final CardView card;

    public ViewHolder(View view) {
        super(view);
        mBusinesssName = (TextView) view.findViewById(R.id.list_item_name_textview);
        mBusinessCategory = (TextView) view.findViewById(R.id.list_item_category_textview);
        mBusinessDistance = (TextView) view.findViewById(R.id.list_item_dist_textview);
        businessImage = (ImageView) view.findViewById(R.id.list_item_icon);
        card = (CardView) view.findViewById(R.id.card_view);

    }
}
}

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();
        }
    });
}

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

在ViewHolder中设置点击监听器，如下所示:

public class MyViewHolder extends RecyclerView.ViewHolder {
    public TextView title, year, genre;

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

        title = (TextView) view.findViewById(R.id.title);
        genre = (TextView) view.findViewById(R.id.genre);
        year = (TextView) view.findViewById(R.id.year);

        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(context, ""+getAdapterPosition(), Toast.LENGTH_SHORT).show();
            }
        });
    }
}
