Android 原生listview item伸展收缩效果 （续）

接上一个原生的listview item的伸展收缩效果。

上一个可能做的有些粗糙，效果也没有这个好，上代码。

package com.example.listviewdemo;

import java.io.Serializable;

/**

public class PurchasedVipInfo implements Serializable {
    private static final long serialVersionUID = 1L;
    private String item;
    private String Ichild;
    private boolean isvisibility = false;
    
    
    public String getItem() {
        return item;
    }

    public void setItem(String item) {
        this.item = item;
    }

    public String getIchild() {
        return Ichild;
    }

    public void setIchild(String ichild) {
        Ichild = ichild;
    }

    public boolean isIsvisibility() {
        return isvisibility;
    }

    public void setIsvisibility(boolean isvisibility) {
        this.isvisibility = isvisibility;
    }
}

效果图就不上了，一个会员特权详情的显示页面

主要是这个方法：

  public View getView(final int position, View convertView, ViewGroup parent)
