Does The Android Ndk Support Locales?
All I really want to do is format a date using strftime('%x') in the right order. On most platforms a call to setlocale('') is enough. On Android I keep getting !@#$ US dates. So,
Solution 1:
No. setlocale()
and strftime()
does not work in Android NDK, except if en_US layout is what you want.
I get the local language from the Java part by:
pLocaleData->pLocaleLanguage = new Locale("en").getDefault().getLanguage();
And the ANSI C localeconv()
does not work in Android NDK:
structlconv *localeconv(void);
Also the standard Unix way of getting user name, does not work in Android.
char *p = getenv("USER");
So you need to use the Java side to get the locale information.
StringLocaleCountry=newLocale("en").getDefault().getCountry();
StringLocaleLanguage=newLocale("en").getDefault().getLanguage();
StringLocaleCurrency=newDecimalFormatSymbols().getCurrency().toString();
StringLocaleShortDateTimePattern=newSimpleDateFormat().toPattern();
charLocaleDecimalSeparator=newDecimalFormatSymbols().getDecimalSeparator();
charLocaleThousandSeparator=newDecimalFormatSymbols().getGroupingSeparator();
StringLocaleThousandGrouping=
String.format("%d;0", newDecimalFormat().getMaximumFractionDigits());
StringLocaleNegativePrefix=newDecimalFormat().getNegativePrefix();
StringLocaleNegativeSuffix=newDecimalFormat().getNegativeSuffix();
StringOperator= Utils.getQwnername(context);
Solution 2:
According to this the answer is No.
There is no support for locales in the C library / from native code, and this is intentional. As Elliot pointed out, your only hope is to use JNI to get relevant values.
