android listView 删除动画 当前Item 删了,但是动画总是从最后一行执行

10

点击ListView 的item中的控件,删除当前item时,想让它一动画的方式 消失,但是,点击删除时,item可以删除掉,但是动画总是执行的最后一行 求解、??

这是主要代码

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(mActivity).inflate(R.layout.layout_dialog_item_detial, null);
holder = new ViewHolder();
holder.tv_time = (TextView) convertView.findViewById(R.id.tv_time);
holder.tv_score = (TextView) convertView.findViewById(R.id.tv_score);
holder.iv_delete = (ImageView) convertView.findViewById(R.id.iv_delete);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}

    DiagHistory dh = historyLists.get(position);
    holder.tv_time.setText(dh.getScanTime());
    holder.tv_score.setText(dh.getDiaScore());
    holder.iv_delete.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            View itemView = (View) holder.iv_delete.getParent();
            removeListItem(itemView, position);
            SQLLiteService.getInstance(mActivity).deleteDialogHistory(holder.tv_time.getText().toString().trim());
        }
    });

    return convertView;
}

class ViewHolder {
    TextView tv_time, tv_score;
    ImageView iv_delete;
}

private void removeListItem(View rowView, final int positon) {
    final Animation animation = (Animation) AnimationUtils.loadAnimation(rowView.getContext(),
            R.anim.remove_dialog_list_item);
    animation.setAnimationListener(new AnimationListener() {
        public void onAnimationStart(Animation animation) {
        }

        public void onAnimationRepeat(Animation animation) {
        }

        public void onAnimationEnd(Animation animation) {
            historyLists.remove(positon);
            DialogItemDetailAdapter.this.notifyDataSetChanged();
            animation.cancel();
        }
    });
    rowView.startAnimation(animation);
}

     View itemView = (View) holder.iv_delete.getParent();  //holder是个全局变量,最后指向界面显示的最后一条,所以你点随便哪一条,都是操作最后一条。这里需要当做参数传入到clicklisten中
                removeListItem(itemView, position);
    重新定义OnClickListener
    class SelfListener implements OnClickListener{
        private View itemView;
            private int positon;
            private String txt;
            public SelfListener(View itemView,int positon,String txt){
                this.itemView  = itemView;
                    this.positon = positon;
                    this.txt = txt;
            }
            @Override
            public void onClick(View v) {
                removeListItem(this.itemView, this.position);
                SQLLiteService.getInstance(mActivity).deleteDialogHistory(this.txt);
            }
    }
    //设置监听
    holder.iv_delete.setOnClickListener(new SelfListener((View) holder.iv_delete.getParent(),position,holder.tv_time.getText().toString().trim()));

    1.removeListItem 这个传参,直接传convertView就可以;
    2.另外你可以用 RecyclerView 代替ListView 这个默认就有动画
    可以看我的博客,并且有demo

    动画可以手动控制啊,当删除item的时候停住动画的播放,并且赋值为null
