推荐答案
经过长时间的研发，我指出我不能直接使用REGEXP.
然后我尝试了
Cursor c = db.rawQuery("SELECT * FROM TODOS WHERE tag LIKE '%"+search+"%' ",null);
After long R&D i came to point that i can not use REGEXP directly.
then i tried
Cursor c = db.rawQuery("SELECT * FROM TODOS WHERE tag LIKE '%"+search+"%' ",null);
，效果很好. 谢谢大家.
and it worked fine. Thanks everybody.
