Android Question xui and customlistvview - alternate row -

[Gianni M]

i use :

Sub Process_Globals
Private xArt As CustomListView
end SUb

and fill xArt

'.....
'.......
dim myheight as int=40dip
Dim p As B4XView = xui.CreatePanel("")
'...........
'..................
p.SetLayoutAnimated(0,0,0,xArt.AsView.Width,myheight)
xArt.Add(p,blc)

and lazy loading / virtualization

Sub xArt_VisibleRangeChanged (FirstIndex As Int, LastIndex As Int)
'...........
'...........
End Sub

now i want insert a SMALL CAPITAL LETTER every time that changes initial of description.
example:

A

ABACO
ABETE

B

BANANA
BARATTOLO
BAZAR

C

CASA
CIPREZZO
CHIODO
CRUDO
and so on

How is the question related to "alternate row"?

The simplest way, especially as you are using lazy loading, is to add the title items to the data store. You haven't written where does the data come from so I cannot say much more.

Try AlfabetListView

There is another example, but using UltimateListView:
