大家好，又见面了，我是你们的朋友全栈君。
实现的效果是这个样子的
看上去效果还是不错，不过现在有个刷新问题一直没能解决，刷新的时候里面的adapter进行刷新的时候总是会让里面的listview消失掉，应该是父listview先刷新完后，子listview还未刷新完成，导致测量的高度不对，就会消失，像当前组已关闭这种，现在这个问题还没有想到办法解决的，试过比较多的方法，添加接口让子listview 刷新完成后再去更新父listview，但还是没有作用，也用过ExpandableListView，但是效果达不到这种，所以没办法还是得用这种办法，有大神知道怎么解决刷新父listview时子listview消失的方法，指导下我，比较奇怪的时候刚开始初始化的时候子listview是默认不显示的，当点击父listview去张开子listview，父listview应该会再次刷新，但子listview展开是可以的，然后下一次更新数据源的时候子listview又会自动关闭，我猜应该是在刷新子listview的时候，父listview先更新完成，子listview的高度测量就没有对！
下面是我的源码
listview 嵌套listview都有个高度测量的问题，在更新的时候动态更新子listview就，下面是布局源码
代码语言：javascript复制<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@ id/grouplinearlayout" android:background="@drawable/item_groupshape" android:orientation="vertical" >

} 然后自己在根据要求补写个子listview的adapter就可以了
