go to where the 6th gym leader is, there is a boat there, get on it and travel to iron island. Once there, team up with a man called riley and defeat team galactic, after this he'll give you a egg, hatch it, it will be a rilou
The answer is put Rilou into the poke'walker before you enter and then when you get in put Rilou back into your game.
In order to evolve Rilou you have to become great friends with it.

You need to have Rilou happy with the egg the man gives you at Stone Island during the day. Go to pokemon.marriland.com
you cant. on iron island team up with riley till you get to the end of the cave then he'll give you a rilou egg.when the egg haches level him up. "friendship evolve". or if you have a exp share you can give it to rilou "make sure rilou is in your pary" get one of you strongest Pokemon and battle Pokemon that it's level are higher than rilou and he will get some points and rilou's level goes up . hope this helped.
to get rilou go to iron island and a man will follow you through a maze and when you finish he will give you lucarios egg which has rilou in side.walk 500 steps and itll hatch (only if its in you Pokemon team).it cannot be caught in the sinnoh
