Save language chosen by user, Android

Question

How can I change default string.xml? I can change my app to five different languages, but whenever I close the app and reopen it. It goes back to default English.

Is it possible to somehow change the default folder "values". For example, from values (English) which is default to values-pt (Portuguese).

Any help is much appreciated!

Answer 1

you can use following

public void loadLocale() {
        String langPref = "Language";
        SharedPreferences prefs = getSharedPreferences("CommonPrefs",
                Activity.MODE_PRIVATE);
        String language = prefs.getString(langPref, "");
        changeLang(language);
    }

public void changeLang(String lang) {
        if (lang.equalsIgnoreCase(""))
            return;
        myLocale = new Locale(lang);
        saveLocale(lang);
        Locale.setDefault(myLocale);
        android.content.res.Configuration config = new android.content.res.Configuration();
        config.locale = myLocale;
        getBaseContext().getResources().updateConfiguration(config,getBaseContext().getResources().getDisplayMetrics());

    }

public void saveLocale(String lang) {
        String langPref = "Language";
        SharedPreferences prefs = getSharedPreferences("CommonPrefs",
                Activity.MODE_PRIVATE);
        SharedPreferences.Editor editor = prefs.edit();
        editor.putString(langPref, lang);
        editor.commit();
    }

and in onCreate()

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_change_language);
        loadLocale();
    }
