how to remove layout at runtime?

[Orlando]

Hi, I don't know if B4A support themes, so, i've created two layouts (white/day and night/black).

if i use activity.loadlayout("white") how can i remove it when i want to use the black layout?

i've tried to load the black layout but when i start another activity i can see the white layout in the background and animations are slow. (DELL STREAK 7)

Thanks i found this usefull thread:

Code: android:targetSdkVersion=14


Code:
SetApplicationAttribute(android:theme,"@android:style/Theme.Holo"

So, how can i change the theme at runtime? from Theme.Holo to Theme.Holo.Light?

This routine will do it:

Sub RemoveViews
 Dim i As Int
 
 For i = Activity.NumberOfViews - 1 To 0 Step -1
  Activity.RemoveViewAt(i)
 Next
End Sub

Best regards.

Can't change back

while this works the first time, you can't go back to
the original layout.

You can use two panels and load each layout to a different panel (with Panel.LoadLayout). You can then hide one panel and show the other.

Hi, thanks for your help.

So, how can i modify this code to remove al views of all opened activities?

Sub RemoveViews
 Dim i AsIntFor i = Activity.NumberOfViews - 1 To 0 Step -1
  Activity.RemoveViewAt(i)
 NextEnd Sub

There could only be a single activity visible at any time.
