Android Question [B4XPages] Where to declare pages?

[Sandman]

I'm converting my app to B4XPages, and I'm wondering if there's a recommendation on where to declare the pages? My app is about a dozen pages, and the user can (sort of) freely jump back and forth between them.

At the moment I've declared all possible destination pages in each page. So if I have the page pageDraw, and the user can go to pageColors, the latter page is actually declared in pageDraw. (As a side-effect, this could mean that I declare pageColors in more than one page - not sure if this is a problem.)

This feels somewhat scattered to me, and not entirely correct. I have the feeling that it's smarter to declare all pages in B4XMainPage instead, to keep that code in one place.

Does the forum have an opinion on what's the better strategy?

In my opinion, declared as public in Class_Globals of B4XMainPage.

 

[Sandman]

Because it's less messy and more centralized?

 

[LucaMs]

Yes and also because you initialize and add them to the B4XPages in that class, so you have no other worries, you are sure they exist.

 

[Sandman]

Yeah, sounds good, I'll move them to B4XMainPage. Thanks

And if you want to create something like this
B4XMainPage -> B4XPage1 -> B4XPage2 -> B4XPage3
How are you calling each page?

 

[LucaMs]

From any page you can show any other page:

B4XPages.ShowPage(PageID) ' PageID is a String.

Or you can show/access them from B4XMainPage:

B4XPages.MainPage.OneOfThePages

You might have a look at chapter 10 B4XPages Navigation through pages and program flow in the B4X Cross-platform projects booklet.
