My dog's keep on barking & others..?

Ok, so, i have a silky terrier

He's five months, and i had him for his fifth month at my house..

Well i just got him a new crate today and put it on the first floor family room and all of the bedrooms are on the second and the third floor..

I take him for a walk twice a day for about 20 minutes (more than enough for and silky terrier) and he never rests in the house as well.

But when it's even at night, he won't sleep and would keep barking, not just because he got a new crate today but he use to bark when we didn't have a crate and just let him hang out in our family room.

Sometimes we thought that it was because he was distracted by the noise from outside (although I, as a human, couldn't hear anything) but then when i went down cause of his excessive barking, he just straightly went to sleep.

I've tried all those kong toys, fav. chew toys, fav. beds method but those wouldn't grab his attention. and if i ever tried to crate train him, as he didn't seem to show any interest in food, i didn't know what was best for him that could grab his attention..

And another thing is that he seems more tired and sleepy in the mornings than in the evenings.. is there a way to make him do the opposite, like making him be more active in the morning rather than evenings?

Thank you!
