问题
I have a list of language codes (as in "en", "es"...) I need to display in those language like this:
English
Español
Français
Deutsch
日本語
Is there any built-in API to get these in Android or should I map them myself?
回答1:
The Locale class have a method for this: public String getDisplayLanguage(Locale locale), as the documentation says:
Returns the name of this locale's language, localized to
locale. The exact output form depends on whether this locale corresponds to a specific language, script, country and variant.
So you can get language names for locales like this:
String lng = "en";
Locale loc = new Locale(lng);
String name = loc.getDisplayLanguage(loc); // English
lng = "es";
loc = new Locale(lng);
name = loc.getDisplayLanguage(loc); // español
//...
