可扩展列表在刷新UI时折叠

Question

我已经实现了以下代码：

explistView.setOnGroupCollapseListener(new OnGroupCollapseListener() { 
    public void onGroupCollapse(int id){  
        ExpandableListView expand=(ExpandableListView) mView.findViewById(R.id.explistview); 
        expand.expandGroup(id); 
    } 
});

仍在UI上刷新可展开列表正在折叠。请帮忙。

尝试使用getGroupView方法，如下所示

@Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
    View v = super.getGroupView(groupPosition, isExpanded, convertView, parent);
    ExpandableListView eListView = (ExpandableListView) parent;
    eListView.expandGroup(groupPosition);
    return v;
}

我希望这会对你有所帮助
