riolu does not evolve by level you have to make it happy by training during the day so avoid training at night, give it lots of massages in veilstone city, feed it zinc, carbos etc, avoid feeding it herbs and making it faint and hopefully it will evolve.
Good Luck! :D
OR
Don't fight with it at all and just walk around with it in your party and give it Massages and zinc, carbos ect and avoid feeding it herbs and when you do finally use int in battle or put EXP share on it you will evolve @ the next lvl, that way you get what ever moves Lucario gets after that lvl.
