Cursor is just an interface. There are at least seven Cursor
implementations in Android, and creating your own is not terribly hard,
particularly if you use AbstractCursor as a base. For example, I have a
JoinCursor implementation that demonstrates creating a wrapping Cursor
that blends two data sources:

That's a typical pattern for *using* a Cursor. You can also hand a
Cursor off to a CursorAdapter to display in a ListView or other form of
AdapterView.
