Android: Get the device interface language in ISO 639 3-letters format?

Question

I am developing an Android application for the global market, which will (hopefully!) be installed by users speaking different languages.

Since I want to adjust my interface language to the device's language, I need to acquire that language name in a convenient, standard format - preferably, ISO 639-2 3-letter format in which Hebrew is heb, English is eng and Spanish is spa.

How can I get the Android interface language in ISO 639-2 3-letter format?

Answer 1

You can use this code snippet:

protected static String lang = Locale.getDefault().getISO3Language();//.substring(0, 2);

I use the 2 chars variant, but I cut that part out, to leave you the 3 chars variant, as required.

Answer 2

List of ISO codes for languages

As you can see, substring the ISO 639-3 (3 letters) code does not make always the ISO 639-1 (2 letters) code. Also I do not recommend this. Choose a hashtable to get the corresponding code.
