In that Krabby club-thing at Gateon Port, there is this sailor dressed in blue on the second floor that will tell you how much that Pokemon likes you
but dont forget the happiness resets when you trade. so if your togepi is not in XD, dont trade it there!! every game has a place where someone will tell you how happy a pokemon is (eg in RSE its in the town to the east of mauville - cant remember its name). they dont give you an exact figure, but just an indication of how happy or sad it is.
