ListView-item-删除

自定义的Baseadapter的getview()中view = inflater.inflate(R.layout.myorder_onelist, null, false);view一定不能设置成全局变量，否则会出现点击删除混乱的情况；

getview()如下:

public View getView(final int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubViewHolder holder=null;View view = null;LayoutInflater inflater = LayoutInflater.from(mycontext);Map<String,String> map = mylist.get(position);if(convertView==null){holder = new ViewHolder();convertView = inflater.inflate(R.layout.myorder_onelist, null, false);convertView.setTag(holder);}else if (((ViewHolder)convertView.getTag()).needInflate) {//折叠式的这里不能缺少holder = new ViewHolder();convertView = inflater.inflate(R.layout.myorder_onelist, null, false);convertView.setTag(holder);}else{holder = (ViewHolder) convertView.getTag();}holder.StartCity = (TextView) convertView.findViewById(R.id.onelist_startcity);holder.EndCity = (TextView) convertView.findViewById(R.id.onelist_endcity);holder.StartTime = (TextView) convertView.findViewById(R.id.onelist_starttime);holder.EndTime = (TextView) convertView.findViewById(R.id.onelist_endtime);holder.delected = (ImageView) convertView.findViewById(R.id.onelist_delecet);holder.date = (TextView) convertView.findViewById(R.id.onelist_time);holder.Photo = (ImageButton) convertView.findViewById(R.id.onelist_photo);holder.delected.setOnClickListener(new Click(convertView,position));holder.StartCity.setText(map.get("Start"));holder.EndCity.setText(map.get("End"));holder.EndTime.setText(map.get("Etime"));holder.StartTime.setText(map.get("Stime"));holder.date.setText(map.get("date"));return convertView;}

介绍两种方式：
1、折叠式的删除：

private void deleteCell(final View v, final int index) {AnimationListener al = new AnimationListener() {@Overridepublic void onAnimationEnd(Animation arg0) {removeItem(index);//自定义的函数ViewHolder vh = (ViewHolder)v.getTag();vh.needInflate = true;}@Override public void onAnimationRepeat(Animation animation) {}@Override public void onAnimationStart(Animation animation) {}};collapse(v, al);}private void collapse(final View v, AnimationListener al) {final int initialHeight = v.getMeasuredHeight();Animation anim = new Animation() {@Overrideprotected void applyTransformation(float interpolatedTime, Transformation t) {if (interpolatedTime == 1) {v.setVisibility(View.GONE);}else {v.getLayoutParams().height = initialHeight - (int)(initialHeight * interpolatedTime);v.requestLayout();}}@Overridepublic boolean willChangeBounds() {return true;}};if (al!=null) {anim.setAnimationListener(al);}anim.setDuration(300);v.startAnimation(anim);}

2、侧滑式：

protected void removeListItem(View rowView, final int positon) {final Animation animation = (Animation) AnimationUtils.loadAnimation(rowView.getContext(), R.anim.item_anim);animation.setAnimationListener(new AnimationListener() {public void onAnimationStart(Animation animation) {}public void onAnimationRepeat(Animation animation) {}public void onAnimationEnd(Animation animation) {removeItem(positon);animation.cancel();}});rowView.startAnimation(animation);}
