Android Question How to use multiple modules and global variable

RushilD said:

Hello, I am fairly new to BRA and would appreciate some help. I tried to search the forums but was not able to figure out the problem.

In my Project I have the following module
1. Main ->Activity Module
2. Starter -> Service module
3. AstreamsText -> Class Module
4. B4XMainPage -> Class Module
5. Overview -> New module


I have a button " "in B4XMainPage .

B4X:

Private Sub overview_Click
    CallSub(overview,"Temperature_By_Room")
End Sub

I have some variables in Main

B4X:

Sub Globals
    Private BTConnect As Button
   
    Private overview As Button  

    Dim climate_temperature As Int
    Dim climate_humidity As Int

    Public Labelbedroomtemp As Label
    Public Labelbathroomtemp As Label
   
End Sub

Problem

When button "overview" is pressed I want to call / run a function in the OVERVIEW module
In that function I was to set some text for the labels Labelbedroomtemp

When I try to access the labels in module overview , IDE shows that the variables climate_temparature and labeldedroomtemp are not declared.

How can I fix this ? How can I share the variable from MAIN to Overview ?

Thank you

To access a variable declared a public in Main from outside of Main you need to do this.

Main.labelbedroomtemp

If the module is a class then you need to initialise an instance of the class first.

What type is your "overview" module. is it a class or a code module?

Assuming this a B4xPages app, you problably shouldn't be declaring Views in Main anyway.
