B4A Library [B4X] [XUI] AS DatePickerTimeline

Alexander Stolte · May 21, 2022

Date Picker Library that provides a calendar as a horizontal timeline.
This library is inspired by a Flutter library, but the B4X one is better

I spend a lot of time in creating views, like this and to create a high quality view cost a lot of time. If you want to support me and further views, then you can do it here by Paypal or with a coffee.

The view has 2 modes:

Paging - you scroll page by page
List - scrolling without snapping

Make all sundays red:

Private Sub AS_DatePickerTimeline1_CustomDrawDay (Date As Long, BackgroundPanel As B4XView)
    Dim xlbl_Date As B4XView = BackgroundPanel.GetView(0)
 
    'Month Name - January
    Dim xlbl_Month As B4XView = BackgroundPanel.GetView(1) 'Ignore
    'WeekDay Name - Monday
    Dim xlbl_WeekDay As B4XView = BackgroundPanel.GetView(2) 'Ignore
 
    If DateTime.GetDayOfWeek(Date) = 1 Then '1=Sunday
        xlbl_Date.TextColor = xui.Color_ARGB(255,221, 95, 96)
    End If
End Sub
