New to making android apps, need some general starting help

[Hiphiphooray]

I already have everything downloaded and have already done the Hello World starting tutorial. I am new to Eclipse but have programmed before in Visual Basic. My normal means of coding in Visual Basic would begin my designing the user interface which consisted of adding controls (such as buttons, textbox, labels). Then i would code what i wanted the controls to do. I am having trouble figuring out how to make controls and how to code them specifically.

For a quick way to answer, If i wanted a simple app to take the value of two text boxes and add them when i clicked a button how would i do this?

Thanks for any help.

I would say start here, Hello, World | Android Developers and then move on once you get the basics. Learning java basics would also be a good start, VB is a completely different world in my opinion
