Android Question B4XDateTemplate - Change of Month/WeekDay

[saza]

Hi there,

for my program I am using the B4XDateTemplate in B4A.

In this template the month on the top right is in english language. Same goes for the weekday. I can't seem to find a way to change them to a different language or even any different term/name.

To make it a bit more clear:
In the picture below you can see that the current month is "July" and the weekdays are "Mo", "Tu", "We", ...
Is there a way to change the month to "I Don't Care" instead of "July" and the weekdays "Mo", "Di", "Mi", ...

I thought that one option could be the following code but it did not seem to work:

Private DateTemplate As B4XDateTemplate
DateTemplate.lblMonth.Text.Replace("July", "I Don't Care")

Thanks in advance.
SaZa

DateTemplate.lblMonth.Text.Replace("July", "I Don't Care")

This line doesn't do anything. String is immutable. You cannot change it by calling a method.

The months and days names should be based on the device locale.
You can force it with this code in Service_Create of the starter service:

Dim jo As JavaObject
jo.InitializeStatic("java.util.Locale").RunMethod("setDefault", Array(jo.GetField("GERMAN")))

You should use File - Export as zip.

 

[saza]

The ZIP is attached. Thanks.

 

[Erel]

Change the code to:

Sub Service_Create
    Dim jo As JavaObject
    jo.InitializeStatic("java.util.Locale").RunMethod("setDefault", Array(jo.GetField("GERMAN")))
    DateTime.DateFormat = "dd.MM.yyyy"
End Sub

This will force the internal formatters to be created and they will be based on the correct locale.

Thanks, Erel.
The code works great!

 

[Erel]

BTW, nice layout!

Thanks

Hello,

Thank you.
