在ExpandableListView上分组数据(Grouping data on an ExpandableListView)

 我在SQLite表中有以下格式的数据： 
 
id|datetime|col1|col2
1|2013-10-30 23:59:59|aaa|aab
2|2013-10-30 23:59:59|abb|aba
3|2013-10-30 23:59:59|abb|aba
4|2013-10-31 23:59:59|abb|aba
5|2013-10-31 23:59:59|abb|aba
 
 我想实现一个ExpandableListView以便数据按datetime分组，并显示如下： 
 
> 2013-10-30 23:59:59 // Group 1
1|aaa|aab
2|abb|aba
3|abb|aba
> 2013-10-31 23:59:59 // Group 2
4|abb|aba
5|abb|aba
 
 我有一个自定义的CursorAdapter ，我可以轻松地使用它来填充ListView ，显示每个项目的日期，但我不知道如何“分组”数据并将其填充到ExpandableListView - 你能不能给我任何提示？ 

I have data in an SQLite table in the following format:
 
id|datetime|col1|col2
1|2013-10-30 23:59:59|aaa|aab
2|2013-10-30 23:59:59|abb|aba
3|2013-10-30 23:59:59|abb|aba
4|2013-10-31 23:59:59|abb|aba
5|2013-10-31 23:59:59|abb|aba
 
I would like to implement an ExpandableListView so that the data would grouped by datetime and shown like that:
 
> 2013-10-30 23:59:59 // Group 1
1|aaa|aab
2|abb|aba
3|abb|aba
> 2013-10-31 23:59:59 // Group 2
4|abb|aba
5|abb|aba
 
I have a custom CursorAdapter that I can easily use to populate ListView, showing date for every single item but I don't know how to "group" the data and populate it on an ExpandableListView - could you please give me any hints?
