How to make multiple layouts in an app?

Question

In html you would use the href, how do I do this in XML (apps)?

Answer 1

I'm really confused. Could you please add a bit more context? I'm not following the whole multiple-layouts-in-html-uses-href train of thought, so it's hard to imagine what you are looking for as an equivalent in XML...

Answer 2

So....
In html, you have a webpage, right? If you click a link, or a button, or literally anything that contains a link, a new html file, a new page, loads and you see that page, not the old one.
Now, in XML I'm looking for something like <a> with the "href" attribute, that opens a new app layout, that the layout looks different.
