Walking is a very inefficient method for raising friendship.

Answer 1

Riolu starts with 70 friendship, unless you catch it in a friend ball or hatch it from an egg.

Walking 128 steps has a 50% chance of raising its friendship by 1, unless you catch it in a luxury ball. Riolu can evolve into Lucario if its friendship is at least 220.

Therefore, it takes 256 steps on average to raise its friendship by 1. 256 * (220 - 70) = 38400 steps. It'll probably evolve faster if you feed it EV berries or level it up.

Wow! Thanks! But I hatched Riolu so? Thanks! And so that means I need To walk 38400 steps to evolve him?

I forgot that Pokemon hatched from eggs start with 120 friendship. In that case, it should take 25600 steps on average to evolve.
