Android Question Text.ToUpperCase for Turkish characters

texwillerx · May 10, 2014

I have a program which uses ToUpperCase function. The function behaves differently according to the language of the system.

When the language for the Android is English, the

ToUpperCase("Lisan")

returns LISAN ("i" is uppered as "I"). But, when the language is set to Turkish, it returns "LİSAN" ("i" is uppered as "İ" which is dotted I of Turkish), which is correct for Turkish, but wrong for English.

The interesting thing is that, this happens only when the program first started.

When the program is "Paused" and "Resumed", the function returns "LISAN" even for Turkish system language.

Please inform me how can I force the ToUpperCase function to return the result as English, independent of the system language.

Call this method when your app starts. It will set the process locale to US:

B4X:

Sub SetUSLocale
   Dim jo As JavaObject
   jo.InitializeStatic("java.util.Locale")
   jo.RunMethod("setDefault", Array(jo.GetField("US")))
End Sub

Thank you very much for your reply, Erel. It worked perfectly.

One thing to mention is that, the RunMethod should be called as

jo.RunMethod("setDefault", Array As Object(jo.GetField("US")))

otherwise the compiler gives an error

... 'as' expected.

This is correct. Unless you are using v3.80 (beta currently). Starting from v3.80 you can omit the type and it will default to object (with Array keyword only).

I have read about 3.80 but will wait until final release.

Thanks again for your valuable help.

Regards.
