在RecyclerView设置监听事件

1.为什么在RecyclerView取消掉了Listview里的OnItemClickListner事件，

简单来说就是因为ListView里的OnItemClickListner与OnClickListner

发生了冲突，OnItemClickListner无法解决多种多样的事件，

所以在Recycerview里面便去掉了OnitemClickListner的方法

2.如何给Recycerview添加监听事件？？？

一般可以想到的方法有两种，关键的关键就是如何去获取position，第一种方法就是在适配器里面getPosition（），但是这个getPosition（）已经过时了，但还有一种方法，对外实现接口，下面就是这个封装了的工具类的代码：

package com.example.com.mlsdome.Activity.Util;import android.content.Context;import android.support.v7.widget.RecyclerView;import android.view.GestureDetector;import android.view.MotionEvent;import android.view.View;/** * Created by 12697 on 2017/3/19. */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) { }    @Override    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept)    {    }}

剩下的就简单了

md_rView.addOnItemTouchListener(new RecyclerItemClickListener(this, new RecyclerItemClickListener.OnItemClickListener() {    @Override    public void onItemClick(View view, int position)    {        switch (position)        {            case 0:                Intent intent=new Intent(MatchDetailsActivity.this,WebViewActivity.class);                intent.putExtra("url","http://www.myexception.cn/mobile/1952989.html");                startActivity(intent);                break;        }    }}));

OK，到这里就完成了
