looping on activity elements

hi,

can anyone help (a sample will be most appreciated) on how do i loop on all labels & edittext elements in my activity ?
what i want to do is to loop across all these elements and change their justification say to from right to left or even better to the opposite (right to left & left to right)

thanks...

do it like this, here I set the font size to all views which have text, after assigning the right text in their tags:

sub set_size
Dim V As View
Dim p As Panel
Dim BT As Button
Dim E As EditText
Dim R As RadioButton
Dim Sp As Spinner
Dim L As Label

For i = 0 To Activity.NumberOfViews - 1
   V = Activity.GetView(i)
      Select V.Tag
         Case "button"
            BT = V
            BT.TextSize = fontsize
         Case  "et"
            E = V
            E.TextSize = fontsize
         Case  "label"
            L = V
            L.TextSize = fontsize
         Case "rb" 
            R = V
            R.TextSize = fontsize
         Case "spinner"
            Sp = V
            Sp.TextSize = fontsize
         Case "panel"
            p = V
            SetPanels(p)   ' do the same for all panel's views
   End Select 
Next
end sub

Another option:

For i = 0 To Activity.NumberOfViews - 1
 Dim L As Label
 If Activity.GetView(i) Is Label Then
  L = Activity.GetView(i)
  L.TextSize = ...
  L.Gravity = ...
End If
Next

Is keyword checks the object type. Button, EditText, CheckBox, RadioButton and ToggleButton are actually subtypes of Label. So they all can be treated as labels.

thanks guys

the issue i was interested was not text size but the text style > horizontal alignment

this is really killing me

Did you try: L.Gravity = Gravity.RIGHT ?

thanks!
will this loop on all fields or just the current view ?
i mean i would like it to loop over ALL project elements
otherwize i will have to do it each time a layout is loaded, in that case is there a form_load like sub ? like in .net visual studio an even that is triggered upon loading the form so i can put the calling there
hope i made myself clear

the reason i need it is for devices that do not have a locale for hebrew so all elements are wrongly justified even if i stated them to right they will be to left so i want to put a checkbox to let the user check it if the justification needs to be altered

do you have a better idea ?

BTW - is there anything like iif ?
iif(a=b,true,false)

thanks pal - the signing link was a life saver

any one can help on iif ?

the gravity issue was nice but did not really solve my problem as i need an easier way to support devices with "real" hebrew and device just with hebrew support as justification is also an issue...

and finally - how do you guys make it to support screens of different sizes without having the app look messy ?

i had it very nicely on my samsung S1 & S2 but on S3 & Note it is not as nice ... as screens are not same size

thanks...
