下面是我的代码片段:

v.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        int newPosition = MainActivity.mRecyclerView.getChildAdapterPosition(v);
        Intent cardViewIntent = new Intent(c, MainActivityCards.class);
        cardViewIntent.putExtra("Position", newPosition);
        c.startActivity(cardViewIntent);
    }
});

v是onCreateViewHolder的视图 c为背景信息

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
}

您可以将clickListener传递给适配器。

在活动中:

private View.OnClickListener mItemClick = new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        Intent intent = null;
        int position = list.getChildPosition(v);
        switch (position) {
            case 0:
                intent = new Intent(MainActivity.this, LeakCanaryActivity.class);
                break;
            case 1:
                intent = new Intent(MainActivity.this, ButterKnifeFragmentActivity.class);
                break;
        }
        if (intent != null) {
            MainActivity.this.startActivity(intent);
        }
    }
};

然后将它传递给适配器:

MainAdapter mainAdapter = new MainAdapter(this, mItemClick);

在适配器的onCreateViewHolder中:

 @Override
public MainAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int position) {
    View itemView = activity.getLayoutInflater().inflate(R.layout.main_adapter_item, viewGroup, false);
    ViewHolder holder = new ViewHolder(itemView);
    itemView.setOnClickListener(mItemClick);
    return holder;
}

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:

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。

下面是我的代码片段:

v.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        int newPosition = MainActivity.mRecyclerView.getChildAdapterPosition(v);
        Intent cardViewIntent = new Intent(c, MainActivityCards.class);
        cardViewIntent.putExtra("Position", newPosition);
        c.startActivity(cardViewIntent);
    }
});

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) {}
}
