2 newbie problems

[Izzi]

I was looking at this video and tried to do what he does:

Problem #1:
My design-mode looks really ugly like this:

(sorry, cant post URLs)

I changed the "text" and also the text-style. Nothing happened. It still says button1. Why?

Problem #2:
I did press the "play" icon and it did compile without errors.
But no emulator showed up.
How do I fix this?

Ok, I did manage to get the emulator working and ran the app. Now the button had the text and the background had the effect I did set.

But why didn't I see this in the designer mode?

The abstract designer will not show what you're asking, it will only show you the position of the views so you can work easily when you design different layouts (read THIS)
