Android Question Combobox typeface change and adding items

[harinder]

Hi..
I was looking to add a string of days as items to a combobox and also change typeface:

    Dim cs As CSBuilder
    Dim myFont As Typeface = Typeface.CreateNew(Typeface.LoadFromAssets("myfont.ttf"), Typeface.STYLE_BOLD)
    Dim s() As String =Array  ("-","7","10","14","30","60","90","180","365")
    For i=0 To s.Length -1
       spnrmks.cmbBox.Addall(Array (cs.Initialize.Typeface(myFont).Append(i).PopAll))
    Next

But I am getting error:
java.lang.ClassCastException: java.lang.Object[] cannot be cast to java.lang.String[]

Halp..Thnx

Change to

Dim s() As String = Array As String("-","7","10","14","30","60","90","180","365")

Strangely, compiling without error , then removing "As String" it did not error again in subsequent compiles (debug mode)

For i=0 To s.Length -1 spnrmks.cmbBox.Addall(Array (cs.Initialize.Typeface(myFont).Append(i).PopAll)) Next

this will add i, the loop variable.

Additional: If you want to use addall you need to create a list with all items first. then add the list with addall.

Shouldn´t it be

For i=0 To s.Length -1
   spnrmks.cmbBox.Add(cs.Initialize.Typeface(myFont).Append(s(i)).PopAll)
Next

to add the items in the Loop?

Mangojack and Donmanfred...getting same error in both cases

1. Why are you accessing the internal cmbbox? You should call SetItems if using B4XComboBox.

2. Please post the full error message from the logs.

Adding items to a list and then changing typeface works fine as follows:

    Dim s As List
    s.Initialize
    s.AddAll(Array As String ("-","7","10","14","30","60","90","180","365") )
    For Each day As String In s
    spndays.cmbBox.Addall(Array(cs.Initialize.Typeface(myFont).Append(day).PopAll))
    Next

Erel... I can use spndays.setitems(s) to add items to the combobox. But how do I change the typeface in this code line? Thnx

 

[Erel]

Your code is fine. You can also use:

Dim Items As List
Items.Initialize
Dim s As List
    s.Initialize
    s.AddAll(Array As String ("-","7","10","14","30","60","90","180","365") )
    For Each day As String In s
     Items.Add(cs.Initialize.Typeface(myFont).Append(day).PopAll)
    Next
 spndays.SetItems(Items)

Hi Erel..thank you
Is it possible to change typeface without using the second list(as in your code) and the internal cmbbox(as in my code)?

I found a posting by Mahares
https://www.b4x.com/android/forum/threads/b4xcombobox-font-on-b4a.118958/post-744284
stating the same. is there no direct method of changing combobox typeface?
I tried effecting change of combobox font via designer, but could not.
Thnx

I'm not sure what you are trying to do. Why does it matter that there is a second list? Does it work?
