Android Question [Solved] How to call a public variable at B4XPages from Another B4xPages

[AndroidMadhu]

Hello,
I am not able to call a public variable from another B4xPages.
The below is the code which I am calling from another page. :

Dim mp As B4XMainPage = B4XPages.GetPage("MainPage")
Log(mp.cloc)
Log(B4XPages.MainPage.cloc)

The variable I declared at MainPage

Sub Process_Globals
Public ActionBarHomeClicked As Boolean
Public cloc As String
End Sub

But I am not able to call cloc from another page.

Please advice

Thanks

I have not played with B4XPages much ...
but I am sure any public variables (or Views) , should be declared in the Page Class_Globals , Not in the Main Activity Process_Globals.

In your case Public cloc As String should be declared in B4XMainPage Class_Globals.

Hello @AndroidMadhu

The best way to do this is with a code module.

Sub Process_Globals
    Dim Name As String
End Sub

The variables of this module can be called anywhere in your application.

Sub AddName
    MiModulo.Name="Bladimir"
End Sub

This is a good solution.

From this thread:

1. We can directly access public global variables of other pages.

For example:

Sub Class_Globals
    Private Root As B4XView 'ignore
    Private xui As XUI 'ignore
    
    Public MyVariable As string

End Sub

In other pages, you can do:

Dim variable as string
variable = B4XPages.MainPage.MyVariable
