2025年android ListView 嵌套 ListView

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

然后是子listview item的布局代码

父listview 的adapter代码

    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
