可默认扩展 ListView 有两个级别。 首先称为“ 分组视图 ”, 第二等级称为“ 儿童视图 ” 。 您可以使用我提供的第一个链接中的自定义适配器样本来实现 。
这里没有几条链接可以让你启动,
为了在某个特定时间使独生子女得到成长,应加上以下内容:
explist.setOnGroupExpandListener(new OnGroupExpandListener() {
public void onGroupExpand(int groupPosition) {
for(int i=0; i<myExpAdapter.getGroupCount(); i++) {
if(i != groupPosition) {
explist.collapseGroup(i);
}
}
}
});
可扩展 ListView 以功能智慧解决您的问题 。

它与普通的 ListView 一起工作! 它得到了光滑的动画。
