有更简单的方法。只需要在根视图上应用onBindViewHolder中的click。

考虑这是你对适配器的看法，

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/linearlayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

        <TextView
            android:id="@+id/textview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="1dp"
            android:textSize="15sp" />
</LinearLayout>

然后在适配器中执行以下操作

//get the layout and make view holder
@Override
public RVAdapter.ViewHolder1 onCreateViewHolder(ViewGroup parent, int viewType) {

    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.adapter_layout, null);
    ViewHolder1 viewHolder = new ViewHolder1(view);
    return viewHolder;
}

@Override
public void onBindViewHolder(RVAdapter.ViewHolder1 holder, int position) {

    //apply on click on your root view
    holder.linearlayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Do on click stuff
        }
    });
}

//make references to views in layout including root view
public class ViewHolder1 extends RecyclerView.ViewHolder {

    protected LinearLayout linearlayout = null
    protected TextView textview = null;

    public CareerLinksViewHolder(View itemView) {
        super(itemView);

        this.linearlayout = (LinearLayout) itemView.findViewById(R.id.linearlayout);
        this.tvCompName = (TextView) itemView.findViewById(R.id.textview);
    }
}

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) {}
}

这里有一个策略，它给出了一个类似于ListView实现的结果，因为你可以在活动或片段级别而不是适配器或ViewHolder级别定义侦听器。它还定义了一些抽象类，这些抽象类负责适配器和持有者的大量样板工作。

抽象类

首先，定义一个抽象Holder，它扩展了RecyclerView。并定义了一个泛型数据类型T，用于将数据绑定到视图。bindViews方法将由一个子类实现，用于将数据映射到视图。

public abstract class Holder<T> extends RecyclerView.ViewHolder {
    T data;

    public Holder(View itemView) {
        super(itemView);
    }

    public void bindData(T data){
        this.data = data;
        bindViews(data);
    }

    abstract protected void bindViews(T data);
}

同样，创建一个抽象适配器，扩展RecyclerView.Adapter<Holder<T>>。这定义了3个接口方法中的2个，子类将需要实现最后一个onViewHolderCreated方法。

public abstract class Adapter<T> extends RecyclerView.Adapter<Holder<T>> {
    List<T> list = new ArrayList<>();

    @Override
    public void onBindViewHolder(Holder<T> holder, int position) {
        holder.bindData(list.get(position));
    }

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

    public T getItem(int adapterPosition){
        return list.get(adapterPosition);
    }
}

具体类

现在创建一个扩展Holder的新具体类。该方法只需定义视图并处理绑定。这里我使用ButterKnife库，但请随意使用itemView.findViewById(…)方法代替。

public class PersonHolder extends Holder<Person>{
    @Bind(R.id.firstname) TextView firstname;
    @Bind(R.id.lastname) TextView lastname;

    public PersonHolder(View view){
        super(view);
        ButterKnife.bind(this, view);
    }

    @Override
    protected void bindViews(Person person) {
        firstname.setText(person.firstname);
        lastname.setText(person.lastname);
    }
}

最后，在持有RecyclerView的Activity或Fragment类中，你会有这样的代码:

// Create adapter, this happens in parent Activity or Fragment of RecyclerView
adapter = new Adapter<Person>(){
    @Override
    public PersonHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.layout_person_view, parent, false);

        PersonHolder holder = new PersonHolder(v);
        v.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View v) {
                int itemPos = holder.getAdapterPosition();
                Person person = getItem(itemPos);

                // do something with person
                EventBus.getDefault().postSticky(new PersonClickedEvent(itemPos, person));
            }
        });

        return holder;
    }
};

在这里添加相同的内容

CustomItemClickListener.java

public interface CustomItemClickListener {
 public void onItemClick(View v, int position);
}

ItemsListAdapter.java

public class ItemsListAdapter extends RecyclerView.Adapter<ItemsListAdapter.ViewHolder> {
ArrayList<ItemListSingleItem> data;

Context mContext;
CustomItemClickListener listener;

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View mView = LayoutInflater.from(parent.getContext()).inflate(R.layout.items_list_single_item, parent, false);
    final ViewHolder mViewHolder = new ViewHolder(mView);
    mView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            listener.onItemClick(v, mViewHolder.getAdapterPosition());
        }
    });
    return mViewHolder;
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    holder.itemTitle.setText(Html.fromHtml(data.get(position).getTitle()));
    if (!TextUtils.isEmpty(data.get(position).getThumbnailURL())) {
      // I Love picasso library :) http://square.github.io/picasso/
        Picasso.with(mContext).load(data.get(position).getThumbnailURL()).error(R.drawable.ic_no_image).
                placeholder(R.drawable.ic_no_image).
                transform(new RoundedCornersTransformation(5, 0)).
                into(holder.thumbnailImage);
    } else {
        holder.thumbnailImage.setImageResource(R.drawable.ic_no_image);
    }
}


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

public ItemsListAdapter(Context mContext, ArrayList<ItemsListSingleItem> data, CustomItemClickListener listener) {
    this.data = data;
    this.mContext = mContext;
    this.listener = listener;
}

public static class ViewHolder extends RecyclerView.ViewHolder {
    public TextView itemTitle;
    public ImageView thumbnailImage;

    ViewHolder(View v) {
        super(v);
        itemTitle = (TextView) v
                .findViewById(R.id.post_title);
        thumbnailImage = (ImageView) v.findViewById(R.id.post_thumb_image);
    }
 }
}

不幸的是，RecyclerView缺少ListView内置的几个功能。 例如，添加OnItemClickListener的能力，当一个项目被单击时触发。 RecyclerView允许你在适配器中设置一个OnClickListener，但是传递那个点击 从你的调用代码，到适配器，再到ViewHolder，监听器是复杂的 要捕捉一个简单的项目单击。

public class ItemClickSupport {
private final RecyclerView mRecyclerView;
private OnItemClickListener mOnItemClickListener;
private OnItemLongClickListener mOnItemLongClickListener;
private View.OnClickListener mOnClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (mOnItemClickListener != null) {
            RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v);
            mOnItemClickListener.onItemClicked(mRecyclerView, holder.getAdapterPosition(), v);
        }
    }
};
private View.OnLongClickListener mOnLongClickListener = new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        if (mOnItemLongClickListener != null) {
            RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v);
            return mOnItemLongClickListener.onItemLongClicked(mRecyclerView, holder.getAdapterPosition(), v);
        }
        return false;
    }
};
private RecyclerView.OnChildAttachStateChangeListener mAttachListener
        = new RecyclerView.OnChildAttachStateChangeListener() {
    @Override
    public void onChildViewAttachedToWindow(View view) {
        if (mOnItemClickListener != null) {
            view.setOnClickListener(mOnClickListener);
        }
        if (mOnItemLongClickListener != null) {
            view.setOnLongClickListener(mOnLongClickListener);
        }
    }

    @Override
    public void onChildViewDetachedFromWindow(View view) {

    }
};

private ItemClickSupport(RecyclerView recyclerView) {
    mRecyclerView = recyclerView;
    mRecyclerView.setTag(R.id.item_click_support, this);
    mRecyclerView.addOnChildAttachStateChangeListener(mAttachListener);
}

public static ItemClickSupport addTo(RecyclerView view) {
    ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support);
    if (support == null) {
        support = new ItemClickSupport(view);
    }
    return support;
}

public static ItemClickSupport removeFrom(RecyclerView view) {
    ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support);
    if (support != null) {
        support.detach(view);
    }
    return support;
}

public ItemClickSupport setOnItemClickListener(OnItemClickListener listener) {
    mOnItemClickListener = listener;
    return this;
}

public ItemClickSupport setOnItemLongClickListener(OnItemLongClickListener listener) {
    mOnItemLongClickListener = listener;
    return this;
}

private void detach(RecyclerView view) {
    view.removeOnChildAttachStateChangeListener(mAttachListener);
    view.setTag(R.id.item_click_support, null);
}

public interface OnItemClickListener {

    void onItemClicked(RecyclerView recyclerView, int position, View v);
}

public interface OnItemLongClickListener {

    boolean onItemLongClicked(RecyclerView recyclerView, int position, View v);
}
}

您还需要定义R.id。使用ids.xml:

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
  <item name="item_click_support" type="id" />
 </resources>

结果代码点击侦听器现在看起来像这样:

ItemClickSupport.addTo(mRecyclerView).setOnItemClickListener(new ItemClickSupport.OnItemClickListener() {
@Override
public void onItemClicked(RecyclerView recyclerView, int position, View v) {
    // do it
}
});

关于recyclerview点击的简要说明，请看看这个littlerobots_blog

根据Yigit Boyar的说法，在RecyclerView上注册点击的最好方法是在ViewHolder的创建中定义点击，而不是仅仅为onBindViewHolder绑定的每个项目创建一个新的onClickListener

例子:

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): BaseViewHolder<*> {
   val itemBinding = LayoutInflater.from(context).inflate(R.layout.my_layout, parent, false)

   val vh = MainViewHolder (itemBinding)
   vh.itemView.setOnClickListener {
       val pos = vh.adapterPosition
       if(pos != NO_POSITION){
           itemClickLister.onCocktailClick(myList[pos],pos)
       }
   }

   return vh
}
