Dependencies:
  1. xCustomListView
  2. XUI / jXUI
Note:
  1. CLV items must be in sorted order.
  2. CLV items should have a label.
  3. CLVIndexScroller will scroll CLV depending upon the first label view of the CLVItem.
  4. After adding/removing CLV items remember to call CLVIndexScroller Refresh function.
Usage:
B4X:
Dim clv As CustomListView
Dim clvIS As CLVIndexScroller

For i=0 To 25
    For j=0 To 7
        clv.AddTextItem(Chr(i+65) & "-Lorem Ipsum" ,"")
    Next
Next
''Initialize (clv As CustomListView, IndexTypeNumeric As Boolean, DarkTheme As Boolean, AscendingOrder As Boolean)
clvIS.Initialize(clv,False,True,True)

''Change active item color
clvIS.SetActiveColor(Colors.Green)

''Set active index theme
clvIS.SetActiveIndexTheme(clvIS.ACTIVE_INDEX_THEME_AUTOPOS)

''Call update to refresh the active index while manual scrolling
Sub clv_ScrollChanged (Offset As Int)
    clvIS.Update
End Sub
