Riolu evolves into Lucario with a high friendship level during the times 4-8 AM.
To reach that high level, treat your Pokemon to a massage, give them items to hold, and fight with them often. Avoid letting your Pokemon faint. If it does, the Pokemon will take longer to evolve/get a higher friendship level.
You must raise Riolu's happiness to the maximum then level it in order for it to evolve into Lucario.
