ANDROID STUDIO was installed today.
It is x270 with win10. There are three questions. Each corresponds to an image.

First, how can I display the preview that has been waiting for 8 hours?

Since there is no design TEXT tab, the design cannot be seen even when switching to mainactivity.

I think I was able to switch gradle with a button like a little Android
I can't find it.

Please give priority to 1 and 2.

By the way, after installing AndroidSTUDIO
Select bottomnav and haven't tampered with anything yet.

I'm seriously troubled. ,,,Thanking you in advance.
