How to get locale with region?

Question

I am trying to get the current device locale with the region like "en_us","en_gb".

I am calling Locale.getDefault().getLanguage() and it returns only the two letters code en.

Answer 1

Format like "en_us" or "en_gb" has "language code"_"country code"

A Locale object contains both country code and language code.

So you can use below snippet to format your own code..

String cCode = Locale.getDefault().getCountry();
String lCode = Locale.getDefault().getLanguage();
String code = lCode+"_"+cCode;

or

you can use toString() method on Locale object to get the data

String code = Locale.getDefault().toString();

Answer 2

It's worth pointing out that locale codes and language tags are related but different. Locale codes have an underscore separator (e.g. fr_CA), and language tags have a dash separator (e.g. fr-ca). I'm sure there are some deeper differences but that's beyond my pay grade.

This answer gives the result of various methods on the Locale class: https://stackoverflow.com/a/23168383

It looks like you want the toString() method (to get the locale code) or the toLanguageTag() (to get the language tag).
