Android Proxy Cursor

I have a database with which I wish to expose data with a ContentProvider. However, it is important that all the colums are not exposed, and also they should be renamed. Is there any good way of doing this? I was thinking maybe some kind of proxy-cursor which takes a cursor and translates its columns to the desired ones, and calls to close and the like would just be replayed to the original cursor. Does s开发者_如何学运维omething like this exist, or would it be hard to make?

You could either implement a CursorWrapper that filters stuff out, or copy the data into a MatrixCursor.
