Answer 1

I'm trying to implement a ViewPager that have multiple activities.

I doubt this is possible, and to the extent that it is, it would use deprecated techniques like ActivityGroup.

What I want is to scroll between different screens, and each screen does its own job.

Use fragments, as @Glendon Trullinger suggested.

How can I build it.

Use the example that you linked to. Or look at the Support13Demos in your SDK's extras/ folder tree, which demonstrate ViewPager. When you have specific, concrete questions regarding the use of fragments, ask another question here on StackOverflow.
