How do i pop up a list of week days (Monday to Sunday) and user should able to select day(s) as require.
For example, when we set the alarm by clicking Repeat, a list of pops up and user can select days(s). I have attached iOS pictures for the reference.

I am looking for a solution supporting B4i and B4A both.

Thank you.

You can set the SelectedItems before showing the dialog and they will be selected:
B4X: 
listtemplate.Options = Array("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday")
    Dim sf As Object = dialog.ShowTemplate(listtemplate, "Ok", "", "Cancel")
listtemplate.SelectedItems = Array("Sunday", "Tuesday") '<-----
Dim sf As Object = dialog.ShowTemplate(listtemplate, "Ok", "", "Cancel")

Dear Erel, thank you very much for the suggestion.
May i further request additional support with some example or link to learn? I have never used B4XDialog + B4XListTemplate.

Thank you very much for your support as always.

B4XDialog is explained here: https://www.b4x.com/android/forum/threads/b4x-input-dialogs-with-xui-views.101197/#content
B4X: 
Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private dialog As B4XDialog
End Sub

Public Sub Initialize
'    B4XPages.GetManager.LogEvents = True
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    dialog.Initialize(Root)
End Sub

Private Sub Button1_Click
    Dim listtemplate As B4XListTemplate
    listtemplate.Initialize
    listtemplate.AllowMultiSelection = True
    listtemplate.MultiSelectionMinimum = 1
    listtemplate.Options = Array("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday")
    Dim sf As Object = dialog.ShowTemplate(listtemplate, "Ok", "", "Cancel")
    Wait For (sf) Complete (Result As Int)
    If Result = xui.DialogResponse_Positive Then
        Log(listtemplate.SelectedItems)
    End If
End Sub

Click to expand...
@Erel , i want to index each object of the list so i used following code. In B4i, it works fine but in B4A, it throws error (screenshot attached). What could be the reason?

list code: 
listtemplate.Options.Set(0, "Sunday")
listtemplate.Options.Set(1, "Monday")
listtemplate.Options.Set(2, "Tueday")
listtemplate.Options.Set(3, "Wednesday")
listtemplate.Options.Set(4, "Thursay")
listtemplate.Options.Set(5, "Friday")
listtemplate.Options.Set(6, "Saturday")
