B4A Library [Class] AnotherDatePicker - A simple "web style" date picker

Status
Not open for further replies.
This is an old version. Latest version is included in XUI Views: https://www.b4x.com/android/forum/threads/100836/#content

AnotherDatePicker is an inline date picker:

The advantage of this class over the built-in dialog (DateDialog from the Dialogs library) is that you can easily customize it as needed.

Most of the layout is created with the visual designer and designer script.

ADP.GetDate returns the selected date.

The months names and days names are based on the device locale.

In order to use this class in your code you should add AnotherDatePicker class, reference DateUtils library and add DatePicker layout file to the Files tab.

Starting from v2.0, ADP should be added as a custom view from the designer:

v2.0 - Better support for visual designer and more configurable options (including first day of week).
v1.11 - Fixes an issue with SetDate that is called before the view is ready.
v1.10 - Adds a Closed event. See the attached example.

After upgrading to the last version the hint text is not displayed anymore. And also it seems that changing the text alignment and the background color in the designer settings doesn't produce any changes. Am I missing something?

You can use:
B4X:
DateTime.DateFormat = DateTime.DeviceDefaultDateFormat
Sorry ... that causes a NumberFormatException: Invalid double: "invalid date"
PackageAdded: package:b4a.example
** Activity (main) Create, isFirst = true **

java.lang.NumberFormatException: Invalid double: "invalid date"

The original code is
B4X:
DateTime.DateFormat = "GGyyyyMMdd"
... but why is it not possible to use
B4X:
DateTime.DateFormat = "dd.MM.yyyy"

How can I get the correct result of the Dateformat for today in Germany = "30.08.2016" in Label1.Text?

Was ist denn das für ein Datumsformat??? Wo kommt das her in dieser Form?

but why is it not possible to use
Warum sollte das nicht gehen?
B4X:
    DateTime.DateFormat =    "dd.MM.yyyy"   
    Dim heute As Long = DateTime.DateParse("19.12.1968")
    Log(DateTime.Date(heute))

Das wüßte ich auch gerne ... es ist wohl das Ergebnis von DateTime.DateFormat = "GGyyyyMMdd"
In diesem Datum sehe ich 2016.08.30 + Uhrzeit 00:00:00 (heutiges Datum um 00:00:00 Uhr)

Mit deinem Code kommt diese Fehlermeldung:
PackageAdded: package:b4a.example
** Activity (main) Create, isFirst = true **
19.12.1968
Error: Invalid value: n. Chr.20160830 000000

Falsch!

DAS ist der Output

** Activity (main) Create, isFirst = true **
19.12.1968

Die Fehlermeldung kommt von einem anderen Code.

Yes thats right, the error message ist the result of that code:
B4X:
Public Sub SetDateAndTime(Years As Int, Months As Int, Days As Int, Hours As Int, Minutes As Int, Seconds As Int) As Long
   
    Dim df = DateTime.DateFormat, tf = DateTime.TimeFormat As String
    DateTime.DateFormat = "GGyyyyMMdd"  '-- Original --   
    DateTime.TimeFormat = "HHmmss"
    Dim d As String = Format(Abs(Years), 4) & Format(Months, 2) & Format(Days, 2)
    d = GetEra(Years < 0) & d
    Dim t As String = Format(Hours, 2) & Format(Minutes, 2) & Format(Seconds, 2)
   
    Try
        Dim ticks As Long = DateTime.DateTimeParse(d, t)
    Catch
        DateTime.DateFormat = df
        DateTime.TimeFormat = tf
            Log("--> Error: Invalid value = Fehler: ungültiger Wert " & d & " " & t)
        Return "--> invalid date = ungültiges Datum" + 1 'hack to throw an error
    End Try
   
    DateTime.DateFormat = df
    DateTime.TimeFormat = tf
        Log("Datum: "&df&" - Uhrzeit: "&tf&"")
    Return ticks

Only the DateTime.DateFormat = "GGyyyyMMdd" is alowed.
This generates the Error: Invalid value: n. Chr.20160830 000000, if you change DateFormat the into DateTime.DateFormat = "dd.MM.yyyy"
