He'll give you smiles and try to do activities with you or he'll try to flirt-like annoy you.
what I do is just kind of talk about what he likes or just be funny because a guy likes a sense of humor.
Be kind, but let him know you aren't interested.
He likes you but wants to know if you like him too.
You be yourself while making some kind of conversation with him... then if he asks you out then you know he likes you or else there's a big problem...
That he likes you?
Answer it depends on if he likes them or if he is that kind of guy you never know
iam in love with this guy but i do not know if he likes me or some other girl
If a guy likes you but you don't know him he may look at you or walk by you whenever possible.
when he says he likes you.

Not sure how you expect someone to magically know something.
