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

<?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" >

    <RelativeLayout  android:id="@+id/listopen" android:layout_width="match_parent" android:layout_height="50dp" >

        <TextView  android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_alignParentLeft="true" android:gravity="center" android:layout_marginLeft="45dp" android:text="默认组" />
         <TextView  android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="match_parent" android:gravity="center" android:layout_alignParentRight="true" android:layout_marginRight="15dp" android:textSize="15sp" android:text="(2)" />

         <ImageView  android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_marginLeft="10dp" android:src="@android:drawable/ic_menu_more" /> 
    </RelativeLayout> 
     <ImageView  android:id="@+id/imageView2" android:layout_width="match_parent" android:layout_height="1dp" android:background="#D8D8D8" />
   <!-- 默认关闭 -->
    <com.baoyz.swipemenulistview.SwipeMenuListView  android:visibility="gone" android:id="@+id/listView1" android:scrollbars="none" android:layout_width="match_parent" android:layout_height="match_parent" >
    </com.baoyz.swipemenulistview.SwipeMenuListView>  
</LinearLayout>

然后是子listview item的布局代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:orientation="horizontal" android:layout_height="50dp">  
       <LinearLayout  android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > 
             <LinearLayout  android:layout_width="wrap_content" android:layout_height="match_parent" android:orientation="horizontal" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" > 
            <RelativeLayout  android:id="@+id/adddeviserelat" android:layout_width="match_parent" android:layout_height="50dp" > 
        <LinearLayout  android:id="@+id/linearLayout25" android:layout_width="180dp" android:layout_height="match_parent" android:layout_marginLeft="46dp" android:orientation="vertical" >

            <TextView  android:id="@+id/device_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="6dp" android:text="device name" android:textColor="#000" android:textAppearance="?android:attr/textAppearanceMedium" />  
            <TextView  android:id="@+id/device_address" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="addr" android:textColor="#ff6699ff" android:textSize="12dp" />
        </LinearLayout>              
        <ImageView  android:id="@+id/singal_imageview" android:layout_width="36dp" android:layout_height="36dp" android:layout_alignParentLeft="true" android:layout_centerVertical="true" android:src="@drawable/car" /> 
        <TextView  android:id="@+id/id_textview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:textColor="#000" /> 
            <ImageView  android:id="@+id/locat_imageview" android:layout_width="18dp" android:layout_height="18dp" android:layout_alignParentRight="true" android:layout_marginRight="40dp" android:layout_centerVertical="true" android:src="@drawable/dingwei" /> 
        <ImageView  android:id="@+id/path_imageview" android:layout_width="18dp" android:layout_height="18dp" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:src="@drawable/guiji" />
    </RelativeLayout> 
     </LinearLayout> 
    </LinearLayout>   
    <TextView  android:layout_height="match_parent" android:layout_width="50dp" android:text="删除" android:background="#ff0000" android:gravity="center"/> 
</LinearLayout>

                    showdelete(Groupinfo, position);
                    break;
                }

            } 
        }); 
        return convertView;
    } 
    public void setListViewHeight(ListView listView,GroupInfo groupinfo) { 
        //获取listView的adapter  
        ListAdapter listAdapter = listView.getAdapter(); 
        if (listAdapter == null) {  
            return; 
        } 
        int totalHeight = 0; 
        for (int i = 0,len = Integer.valueOf(groupinfo.getCount()); i < len; i++) { 
            View listItem = listAdapter.getView(i, null, listView); 
            listItem.measure(0, 0); 
            totalHeight += listItem.getMeasuredHeight(); 
        }     
        ViewGroup.LayoutParams params = listView.getLayoutParams(); 
        params.height = totalHeight + (listView.getDividerHeight() *  (Integer.valueOf(groupinfo.getCount())- 1)); 
        listView.setLayoutParams(params); 
    }
    class ViewHolder {
        TextView    mDevNameTextView; // 名称
        TextView    mDevNumberTextView; // 在线数量
        SwipeMenuListView   Deviceinfo;
        RelativeLayout  listopen;
        LinearLayout    GroupLinear;
        DevControlListAdapter adapter;
        boolean     Isopen = false; 
    }
      private int dp2px(int dp) {
            return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, GlobalVarData.gResources.getDisplayMetrics());
        }
      private  int px2dp(int px) {
          return (int) ((px*160)/GlobalVarData.gResources.getDisplayMetrics().density);
      } 
}

然后自己在根据要求补写个子listview的adapter就可以了
