[Late answer, just for the record. EDITed to remove my suggestion that subclassing is necessary.]

To use SimpleCursorAdapter with an AutoCompleteTextView, you need to set two handlers on the adapter: The CursorToStringConverter, and the FilterQueryProvider. Pseudocode follows:

    adapter.setCursorToStringConverter(new CursorToStringConverter() {
        public String convertToString(android.database.Cursor cursor) {
            // Assume that "someColumn" contains the strings that we want to
            // use to identify rows in the result set.
            final int columnIndex = cursor.getColumnIndexOrThrow("someColumn");
            final String str = cursor.getString(columnIndex);
            return str;
        }
    });

    adapter.setFilterQueryProvider(new FilterQueryProvider() {
        public Cursor runQuery(CharSequence constraint) {
            // runSomeQuery will look for all rows in the database
            // that match the given constraint.
            Cursor cursor = runSomeQuery(constraint);
            return cursor;
        }
    });
