Android listview with nested CursorAdapters? -

-
i trying implement variation on simple master-detail view, can't seem find out there relates particular issue. it's possible , not searching on right terms, in case, i'd appreciate point in right direction. instead of standard master-detail approach planning on, i'd display detail in master listview textview ellipsis, , display popup dialog. for record in master table, there 1...n detail records, need access when displaying master listview. i've looked @ cursorjoiner, don't think fits needs, require cursors sorted on record id, display want them ordered alphabetically. is possible , idea nest cursoradapters? in master cursoradapter, have new cursorloader load details item. or there better way go this?
