ListView侧滑删除----->SlideView

时间过得真快，国庆小长假就结束了，好伤心呜呜—-已经开始了，我去，已经结束了？明天小伙伴们要继续上班了！该收收心好好工作了！有木有很激动！哈哈！相信大家对listview应该非常熟悉了，可以说耳闻能祥！我这里就不再赘述了，言贵正传！大家先看下效果

主要分为下面五种
-PrivateListingAdapter
-SlideListViewActivity
-SlideListView
-SlideView
-MessageBean

首先说下adapter跟普通适配器一样继承BaseAdapter然后实现OnClickListener监听事件，当用户想有侧滑时移除SlideListView中item中的某一项position，然后notifyDataSetChanged();通知listview刷新数据。
主要代码如下

 holder.deleteViewHolder.setOnClickListener(new OnClickListener() {                                @Override                        public void onClick(View v) {                            // T删除某一个item                            mList.remove(position);                            //刷新数据                            notifyDataSetChanged();                        }                    });SlideLsitViewActivity主要负责绑定SlideListView，然后通过更改Model实现数据的更新private void initView() {        // 初始化操作        mSlideListView=(SlideListView) findViewById(R.id.slidelv);        adapter=new PrivateListingAdapter(this);        //创建一个list列表        ArrayList<MessageBean> mMessageList = new        ArrayList<MessageBean>();        for (int i = 0; i < 20; i++) {            //遍历item            MessageBean bean=new MessageBean();            //判断当前取模为3是否等于零然后添加相应的信息            if(i % 3==0){                bean.iconRes=R.drawable.default_qq_avatar;                bean.title="网易新闻";                bean.msg="创智播客创始人猝死";                bean.time="2016-10-06";            }else{                bean.iconRes=R.drawable.wechat_icon;                bean.title="搜狐新闻";                bean.msg="杨洋地铁与粉丝骚扰";                bean.time="2016-10-04";            }            //将Model添加到集合中            mMessageList.add(bean);        }               

下面进行适配器的绑定以及实现OnItemClickListener监听事件打印相应的position位置代码如下

      adapter.setmMessageItems(mMessageList);        mSlideListView.setAdapter(adapter);        mSlideListView.setOnItemClickListener(this);

SlideListView继承ListView重写ListView中方法以及实现当手指向右滑动的监听记录当前手指记录的x,y轴坐标，然后判断当前是开始滑动，还是停止滑动，还是右滑等，实现代码如下

public boolean onTouchEvent(MotionEvent ev) {    // TODO Auto-generated method stub    switch (ev.getAction()) {    /**手指按下**/    case MotionEvent.ACTION_DOWN:        int x=(int) ev.getX();        int y=(int) ev.getY();        int pos=pointToPosition(x, y);        Log.i(TAG, "pos="+pos);        if(pos!=INVALID_POSITION){            MessageBean msg=(MessageBean) getItemAtPosition(pos);            mSlideView=msg.mSlideView;            Log.i(TAG, "mSlideView="+mSlideView);        break;

SlideView主要实现手指侧滑时的OnSlideListener事件，代码如下

 public void onRequireTouchEvent(MotionEvent event){        int x=(int) event.getX();        int y=(int) event.getY();        int scrollX=getScrollX();        Log.d(TAG, "x="+x+"y="+y);           switch (event.getAction()) {           case MotionEvent.ACTION_DOWN: {               if (!mScroller.isFinished()) {                   mScroller.abortAnimation();               }               if (mOnSlideListener != null) {                   mOnSlideListener.onSlide(this,                           onSlideListener.SLIDE_STATUS_SCROLL);               }               break;           }           case MotionEvent.ACTION_MOVE: {               int deltaX = x - mLastX;               int deltaY = y - mLastY;               if (Math.abs(deltaX) < Math.abs(deltaY) * TAN) {                   break;               }               int newScrollX = scrollX - deltaX;               if (deltaX != 0) {                   if (newScrollX < 0) {                       newScrollX = 0;                   } else if (newScrollX >mHoldeWid) {                       newScrollX = mHoldeWid;                   }                   this.scrollTo(newScrollX, 0);               }               break;           }           case MotionEvent.ACTION_UP: {               int newScrollX = 0;               if (scrollX - mHoldeWid * 0.75 > 0) {                   newScrollX = mHoldeWid;               }               this.smoothScrollTo(newScrollX, 0);               if (mOnSlideListener != null) {                   mOnSlideListener.onSlide(this,                           newScrollX == 0 ?   onSlideListener.SLIDE_STATUS_OFF                                   : onSlideListener.SLIDE_STATUS_ON);               }               break;           }           default:               break;           }           mLastX = x;           mLastY = y;       }

   MessageBean  里面主要包括一些图片资源，标题，信息，时间以及SlideView侧滑，代码如下。

 public int iconRes;    public String title;    public String msg;    public String time;    public SlideView mSlideView;    

基本功能就这些，主要通过手向右侧滑然后删除ListView中某一项的item中position，然后适配器Adapter通知ListView刷新。下面是全部代码！
