先給出解決方案：

在調(diào)用notifyDataSetChanged()后，使用一下方法收縮一次。

// i 為更新的子view的position，如果全部更新，遍歷全部子view

* resultsListView.collapseGroup(i); //收起

* resultsListView.expandGroup(i); //展開

* 兩個方法后，數(shù)據(jù)才能在界面上正常刷新

代碼中的用法：

public void addTheReplyData(CommentExpandableListView expandableListView, ReplyDetailBean replyDetailBean, int groupPosition){

if(replyDetailBean!=null){

Log.e("yuan", "該刷新回復列表了:getReplyList = "+commentBeanList.get(groupPosition).getReplyList());

? ? ? ? if(commentBeanList.get(groupPosition).getReplyList() !=null ){

Log.e("yuan", "addTheReplyData: >>>>>replyList不為空 size = "+commentBeanList.get(groupPosition).getReplyList().size() );

? ? ? ? ? ? commentBeanList.get(groupPosition).getReplyList().add(replyDetailBean);

? ? ? ? }else {

Log.e("yuan", "addTheReplyData: >>>>>replyList為空 " );

? ? ? ? ? ? List replyList =new ArrayList<>();

? ? ? ? ? ? replyList.add(replyDetailBean);

? ? ? ? ? ? commentBeanList.get(groupPosition).setReplyList(replyList);

? ? ? ? }

notifyDataSetChanged();

? ? ? ? //

? ? ? ? for(int i =0; i

expandableListView.expandGroup(i);

? ? ? ? }

//

? ? }else {

throw new IllegalArgumentException("回復數(shù)據(jù)為空!");

? ? }

}
