NO.1：在自己定义适配器的ViewHolder里面写监听事件

//RecyclerView适配器    public class RecyclerViewAdapter extends RecyclerView.Adapter
      
        {
              private Context mContext;        private LayoutInflater mLayoutInflater;        private String[] mCityName;        public RecyclerViewAdapter(Context mContext) {            this.mContext = mContext;            mLayoutInflater = LayoutInflater.from(mContext);            mCityName = mContext.getResources().getStringArray(R.array.city_name);        }        //创建新ViewHolder，被LayoutManager所调用        @Override        public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {            return new RecyclerViewViewHolder(mLayoutInflater.inflate(R.layout.item_text, parent, false));        }        //将数据与界面进行绑定的操作        @Override        public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {            ((RecyclerViewViewHolder) holder).mTextView.setText(mCityName[position]);        }        //获取数据的数量        @Override        public int getItemCount() {            return mCityName == null ? 0 : mCityName.length;        }        //自己定义的ViewHolder，持有每一个Item的的全部界面元素        public class RecyclerViewViewHolder extends RecyclerView.ViewHolder {
                  TextView mTextView;            public RecyclerViewViewHolder(View itemView) {                super(itemView);                mTextView = (TextView) itemView.findViewById(R.id.tv_city);                itemView.setOnClickListener(new View.OnClickListener() {                    @Override                    public void onClick(View v) {                        ToastUtil.show(mContext, getPosition() + "");                    }                });            }        }    }
      

NO.2：封装个监听类

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
          private OnItemClickListener mListener;    public interface OnItemClickListener {
              public void onItemClick(View view, int position);    }    GestureDetector mGestureDetector;    public RecyclerItemClickListener(Context context, OnItemClickListener listener) {        mListener = listener;        mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {            @Override public boolean onSingleTapUp(MotionEvent e) {                return true;            }        });    }    @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.getChildPosition(childView));            return true;        }        return false;    }    @Override public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) { }}

用法:

mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);mRecyclerView.addOnItemTouchListener(new RecyclerItemClickListener(this, new RecyclerItemClickListener.OnItemClickListener() {    @Override    public void onItemClick(View view, int position) {         ToastUtil.show(OneActivity.this, position + "");         }    }));
