SwipeView change the content of 2 pages

I've created a new activity with swipe views, and added some code.

I have now two swipeable pages, but with the same content, how can i change the content of the second swipe page.

Do I have to create a new activity or just to redirect it to another xml?

based on the page number you get from Placeholder Fragment you can set the new content
