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();
    }
