Android Question [Solved]Assign an array of views in declaration

Martincg · Oct 19, 2019

I wanted to get a layout approximately correct using the designer. I have 5 sets of views in one area.
I wanted to set the layout correctly in code.
so I did this

B4X:

Private arDay() As Label = Array As Label(lblDay0, lblDay1, lblDay2, lblDay3, lblDay4)

But I found I had to do this

B4X:

Private arDay(5) As Label

'then
 arDay(0)initialize("")
arDay(0) = lblDay0

which partly defeats my plan.
Obviously I can add the labels and other views programmatically, but is there a way to assign arrays of views in a declaration?

If you have lblDay0, lblDay1, lblDay2, lblDay3, lblDay4 in a layout and you load it, no need to Initialize the Labels.

The code below works:

B4X:

Sub Globals
    Private lblDay(), lblDay0, lblDay1, lblDay2, lblDay3, lblDay4 As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Main")
    lblDay = Array As Label (lblDay0, lblDay1, lblDay2, lblDay3, lblDay4)
   
    For i = 0 To lblDay.Length - 1
        lblDay(i).Text = "Test " & i
    Next
End Sub
