Android - Changing Views

[Hightower]

Hi folks,

 

I'm taking a peak into Android, and have two views. I have main.xml and newsselection.xml

 

When the user clicks a button from the main view, I want it to load the newsselection view which will show a stream of news items. Also, when the user presses the back button (the hard one on the device), I want it to go back to the screen before.

 

Something like this kind of structure:

 

Main.xml

|________ newsselection.xml ____________ singleitemnewsview.xml

|________ anotherxml.xml

 

So if the user was as far down as singleitemnewsview.xml and pressed the hard back button it would go up a level to newsselection.xml, and once more would take them up to main.xml

 

Would this be done using a viewswitcher method? Or would it be achieved by starting a new activity for each new view?

 

I'm struggling to find docs on this one, so hope someone can help.

 

Thanks,
