Hi, I'm keen to use the new anotherdatepicker.b4xlib but I'm at a loss to how to use it, the examples look very good but they seem to rely on a DateTemplate, and apparently there's loads of templates, unfortunately I can't seem to find them or get the new anotherdatepicker to work, I've looked at the example Xui Views Example but can't figure out How I would transfer the way the btnDate would transfer into my app, I've tried and I thought I had added the required libraries etc but I get unknown member showtemplate and I've no idea where to find the DateTemplate

You need B4XDialog , B4XDateTemplate. (both in XUI Views Lib).Here is a complete project that displays the date dialog and let you select a date and automatically paste it to a label. Make sure you check XUI Views library.
B4X: 
Sub Globals
    Private Dialog As B4XDialog   'need XUI Views 2.30 checked (internal lib)
    Private DateTemplate As B4XDateTemplate
    Private XUI As XUI  'you declare this if you use the XUI colors
    Private lbl As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
    lbl.Initialize("lbl")
    Activity.AddView(lbl,300dip,0,150dip,75dip)  'via code, but you can do it via designer
    lbl.Color=XUI.Color_Blue
    Dialog.Initialize (Activity)
    Dialog.Title = "Select a date"
    DateTemplate.Initialize
    DateTemplate.MinYear = 2016
    DateTemplate.MaxYear = 2030
    Wait For (Dialog.ShowTemplate(DateTemplate, "", "", "CANCEL")) Complete (Result As Int)
    If Result = XUI.DialogResponse_Positive Then
        Log($"Selected Date is: ${DateTime.Date(DateTemplate.Date}"$ ))
        lbl.Text=DateTime.Date(DateTemplate.Date)
        lbl.TextColor =XUI.Color_Yellow
    End If   
End Sub

Just to add ... That AnotherDatePicker.b4xlib was created as an example only to demonstrate the new .b4xlib's.

AnotherDatePicker.b4xlib

Something strange when I use this b4xlib https://www.b4x.com/android/forum/threads/new-feature-b4x-lib-a-new-type-of-library.100383/ I have "unpacked" the b4xlib file and briefly looked at the code in the class module but cannot pick up why the "Cancel" button shows "720" and not "Cancel" as...

Hi, I know I am basic and learning very slowly but I can't get the logic to work in my existing program my version of XUI Views is showing 2.24 and I can't find the version you mention 2.30

I've tried ding via a designer form, but can't get it to work, all I want is basically the Activity_create to get todays date in YYYY-MM-DD format, assign it to a text field and then have a button which launches the DateTemplate (anotherDatePicker) where the user can select a date, updating the text field,

It can't be that hard but understanding the code is proving to be too difficult as I seem to be going round and round creating different errors,

Sorry to be so dumb

The latest version of B4X Views lib (internal library) is at the end of post 1 in this link:

[B4X] XUI Views - Cross platform views and dialogs

XUI Views is a b4x library (https://www.b4x.com/android/forum/threads/100383/#content). The same b4xlib library is compatible with B4A, B4i and B4J It is a collection of custom views and dialogs. Everything is written in B4X. The source code is included inside the b4xlib file, which is a zip...

But you are probably ok with the version you have.
Here is a complete project attached you can unzip and run and will do what you asked for:
B4X: 
Sub Globals
    Private Dialog As B4XDialog   'need XUI Views 2.30 checked (internal lib)
    Private DateTemplate As B4XDateTemplate
    Private XUI As XUI  'you declare this if you use the XUI colors
    Private edt As EditText
    Private btn As Button
End Sub

Sub Activity_Create(FirstTime As Boolean)  
    Activity.LoadLayout("main")   'has a button and an edittext
    Dialog.Initialize (Activity)
    Dialog.Title = "Select a date"
    DateTemplate.Initialize
    DateTemplate.MinYear = 2016
    DateTemplate.MaxYear = 2030
    DateTime.DateFormat= "yyyy-MM-dd"
    edt.Text=DateTime.Date(DateTime.Now)
    edt.Color=XUI.Color_Red
End Sub

Sub btn_Click
    Wait For (Dialog.ShowTemplate(DateTemplate, "", "", "CANCEL")) Complete (Result As Int)
    If Result = XUI.DialogResponse_Positive Then
        Log($"Selected Date is: ${DateTime.Date(DateTemplate.Date}"$ ))
        edt.Text=DateTime.Date(DateTemplate.Date)
        edt.TextColor =XUI.Color_Yellow
    End If   
End Sub

Very good, easy to understand, thanks a lot
But when I copy your example into my form when I click the 'btn' (btn_click) I get the following error
B4X: 
b4xdialog$ResumableSub_ShowTemplateresume (java line: 1150)
Any idea's

Your best bet is to export your project as zip to the forum. Someone will probably figure it out for you, if I do not get to it or unable to.
You may try to make sure you have the latest XUI Views lib, just in case.

I've added another activity page to the project and copied your code into that page and it works as it should so there's obviously a conflict somewhere in my code, I'll have a good look and get back to you, thanks

Hi, I've put part of my program as a separate app to try and identify via I can't access the DatePicker as shown in the example so generously supplied by Mahares, I have tried many ways to get round it but can't find where i am going wrong. Please excuse the basic coding, any suggestions gratefully received, many thanks Colin

You forgot to add these 2 lines: below this line: SetHeader(Array As String("Date","From","To","Consumption"))
B4X: 
 Dialog.Initialize (Activity)   'this one
    Dialog.Title = "Select a date"   'also this one.
I took a very quick look at the project. Once you add the 2 lines, it will show you the date template. After that, I do not know what you do with the date. But at least you can select your date and it shows you the date selected in the logs..
