Android Question looping thru labels

[merlin2049er]

I looked at some of the examples in the pdf and online but couldn't quite figure out how to apply changes to "x" number of labels in a for next loop.

Just like to clean up my code a bit.

For i = 0 To Activity.NumberOfViews - 1


      If Activity.GetView(i) Is Label Then


         Dim lbl As Label 


         lbl = Activity.GetView(i)


      End If


   Next

Note that this loop will also "catch" Button, EditText, CheckBox and RadioButton as they are all subclasses of Label.

Then how about this,

For i = 0 To Activity.NumberOfViews - 1
      If Activity.GetView(i) Is Button    OR _
         Activity.GetView(i) Is EditText  OR _
         Activity.GetView(i) Is CheckBox  OR _
         Activity.GetView(i) Is RadioButton Then
   
       Else If Activity.GetView(i) Is Label Then
           Dim lbl As Label
           lbl = Activity.GetView(i)
       End If
  Next

sweet.

' oloron font
Dim i As Int


For i = 0 To Activity.NumberOfViews - 1

If Activity.GetView(i) Is Label Then

Dim lbl As Label

lbl = Activity.GetView(i)
lbl.Typeface = oloron

End If

Next

That works fine. I loaded the font in activity_create (first time).

You can use the Tag property for each label and set it by the designer to "lbl"
Now use the Tag property to identify the label:

Dim vi As View
Dim lb As Label
 
For i=0 To activity.NumberOfViews-1
   vi=Activity.GetView(i)
 
   If vi.Tag="lbl" Then
       lb=activity.GetView(i)
      'lb.Color=Colors.Transparent
      'lb.TextColor=Colors.RGB(0,0,139)
   end if
Next
