问题描述
The task is to combine data from 2 different tables with similar columns, sorted by one column . Seems like MergeCursor might help, but have no idea how to sort items.
The only solutions I see now is converting manually to ArrayAdapter, or do sneaky JOINs (not sure yet its possible)
Thanks.
推荐答案
MergeCursor does not offer sorting.

I have no idea what the latter is. If you want to stick with the Cursor interface, you can build yourself a MatrixCursor. Or, you can try to create your own CursorWrapper that maintains the sort order and rewrites all position-related calls.
