Android Question How can I reload a B4XPage?

Sergey_New · Feb 13, 2022

For Activity I do this:

B4X:

Sub cmbFontSize_SelectedIndexChanged (Index As Int)
    Starter.TextSize=Starter.TextSizeMin+Index
    function.setViewHeight(Activity)
    Activity.Finish
    StartActivity(Me)
End Sub

Okay. Then you should call your sub in B4XPage_appear rather than B4XPage_created.

But if you are okay with your post #6 too its fine

B4X:

Private Sub B4XPage_Appear
    'Your sub here
End Sub

It doesn't seem like a good idea to close a page from within and reopen it (same thing for an Activity).

You could move the necessary code from the B4XCreated to a (your custom) Sub and call it.

LucaMs, thanks!
Unfortunately, this does not raise B4XPage_Created.
I have the necessary actions take place there.
If there is no other solution, I will have to move the necessary actions to B4XPage_Appear.

It is precisely due to the fact that Created is executed only once that I have suggested to you...

B4X:

Sub cmbFontSize_SelectedIndexChanged (Index As Int)
    Starter.TextSize=Starter.TextSizeMin+Index
    
    '-------------------------------------------
    'function.setViewHeight(Activity)
    function.setViewHeight(Root) 'You can use Root or Me in place of Activity
    
    '-----------------------------------------
    'Activity.Finish
    'StartActivity(Me)
    B4XPages.ShowPageAndRemovePreviousPages("MainPage") 'Use the ID of the page you want to goto
End Sub

mcqueccu, my page to reload is "Settings".
This code works:

B4X:

Sub cmbFontSize_SelectedIndexChanged (Index As Int)
    Starter.TextSize=Starter.TextSizeMin+Index
    function.setViewHeight(Root)
    B4XPages.ShowPageAndRemovePreviousPages("MainPage")
    B4XPages.ShowPage("Settings")
End Sub

What of This. Change the MainPage to Settings and remove the last line

B4X:

Sub cmbFontSize_SelectedIndexChanged (Index As Int)
    Starter.TextSize=Starter.TextSizeMin+Index
    function.setViewHeight(Root)
    B4XPages.ShowPageAndRemovePreviousPages("Settings")
End Sub
