Android Question Changing properties of views on the fly

kostefar · Mar 12, 2017

Dear All,

If I know all names of all views in all layouts that I have, I can indeed manually change them as I want to - for instance the font color of all buttons.
This is alot of code though, rather than if I´d be able to just iterate through the views with a loop, like:

B4X:

for i = 0 to activity.numberofviews - 1
if activity.getview (i) = button then activity.getview(i).font.color = colors.blue
next

So, how would I do that?

Thanks!

Thanks KMatie, this is exactly what I needed! For others who should have this question in the future, the below will modify the text displayed on all buttons in an activity:

B4X:

For Each v As View In Activity.GetAllViewsRecursive
    If v Is Button Then
        Dim b As Button = V
    
        b.Text = b.Text & "haha"

    End If
    Next
