How to detect Russian for localizing app in Android

Question

I have an app that needs to support Engligh, Spanish, and Russian.

To detect this, I use this method:

UserLanguage = setLanguage(Locale.getDefault().getDisplayLanguage());

UserLanguage is "en" if English, "es" is Spanish, and it needs to be "ru" if Russian, otherwise it will be English. However, when I set the locale on my phone to Russian, it is not detected. The documentation on the Android website does not say anything about Russian. Any help?

private String setLanguage(String locale){
    //Toast.makeText(context, locale.toString(), Toast.LENGTH_SHORT).show();
    if(locale.equals("English")){
        UserLanguage="en";
    }else{
        if(locale.equals("español")){//espanol
            UserLanguage="es";
        }else{
            if(locale.equals("ru")){//cant compile with true russian
                UserLanguage="ru";
            }else{
                //I give up.... english??
                UserLanguage="en";
            }
        }
    }
    return UserLanguage;
}

Answer 1

For Russian Locale.getDefault().getDisplayLanguage() will return "русский"

Try this instead:

        if(locale.equals("русский")){ 
            UserLanguage="ru";
        }else{
            //I give up.... english??
            UserLanguage="en";
        }

But much better solution is to use getLanguage(), instead of getDisplayLanguage():

private String setLanguage(String locale){ 
    if (locale.equals("es")){
        mUserLanguage = "es";
    } else if(locale.equals("ru")){
        mUserLanguage = "ru";
    } else { 
        mUserLanguage = "en";
    }
    return UserLanguage;
}

setLanguage(Locale.getDefault().getLanguage());
