Android : Android: When creating a tab to display an RSS feed should a new layout be created?

Im creating a workout app for myself and some friends and have decided to add an RSS feed in one of the tabs. I have no experience dealing was rss so have a couple questions before I dive in:

As my app contains 3 tabs should I create the rss view on a separate xml layout ? or can I create it on my main xml layout ?

Can anyone recommend any good rss reader tutorials?

Thanks
