Which Android control to use?

Question

I am taking my first steps in Android programming.

My application is to create records in a database. For this task, I created a new activity. Everything is fine, but I don’t really like how it looks.

The emulator currently shows this:

I would like to have something similar to the "New Contact" activity:

• Buttons at the bottom of the window, not under other controls (I hope I find out myself)
• Buttons inside a beautiful “rectangle” as shown in the screenshot (which control is located here?)
• When the soft keyboard is displayed, the buttons should “move up”. If there is not enough space there, the entire area should be scrollable (I'll try to figure it out too)

A sample can be seen here:

You can put them in LinearLayout and assign a weight from 1 to each of the buttons. Also, if you have your own phone / or you want to see the user interface of the application in the emulator - there is a very cool call to the tool hierarchy http://developer.android.com/guide/developing/tools/hierarchy-viewer.html and you can see how you like the user interface of the application.
