Android Question Handling a lot of layout files

[trueboss323]

Hey, so I have got a very basic question. On my app I have a lot of different layout files. Everytime the user presses a button on one layout file it loads the next one. In Visual Basic, we call these Forms. So my question is how can I make this easy? Like the user presses a button, it closes the current layout and loads the next one. On VB, the code would be like:

Form2.Show
Me.Close

So how would I make it similar like in B4A?

You can think to Activity = Form and layout as the content (Views = Controls) of an Activity.

Form2.Show = StartActivity(Activity2)
Me.Close = Activity.Finish

Thanks @LucaMs
I've been wondering about this myself. I didn't realise that it would be as easy as that.

The problem with this code is that it takes a while to load the new activities. And this can be a pain, especially when going through a lot of layouts. Is there anyway to make the loading faster?

 

[LucaMs]

To open a new Activity, StartActivity is the way (there also Intents, which are not more fast) and it is not slow.

If loading is slow, the problem may depend on what you load before the Activity is displayed (for example if you are connected to Internet to download something or if the layout to be loaded contains hundreds of views).

Mostly the activities just contain labels and buttons and yet the loading can still be a bit slow.

Can you post your project (or send it to Erel)?

I have compiled a sample app. Please take a look at the file.

Loading is not slow (real device - release mode).

The only "flaw" is the positioning of views.

Compared to using Activity.RemoveAllViews and Activity.LoadLayout, the loading is much faster. But then I would have to use a single Module for it, which would create a mess in the code.

I think that the best solution is to use multiple activities.
