Language not changing for items in listView (Android)

Question

I have an app that uses 2 languages. When i press the button to change language, it changes for the strings in the menu and navigation drawer but does not changes for items in the listView. Here is my code.

 private void showChangelanguageDialog() {
    //array of languages to display
    final String [] languages = {"English","Shona"};
    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    builder.setTitle(getString(R.string.choose_language));
    builder.setSingleChoiceItems(languages, -1, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            if (which == 0){
                //english
                setLocale("en");
                recreate();
            }
            if (which == 1){
                //shona
                setLocale("sn");
                recreate();
            }
            //dismiss alert dialog when language is selected
            dialog.dismiss();
        }
    });
    AlertDialog alertDialog = builder.create();
    alertDialog.show();
}

private void setLocale(String lang) {
    Locale locale = new Locale(lang);
    Locale.setDefault(locale);
    Configuration configuration = new Configuration();
    configuration.locale=locale;
    getBaseContext().getResources().updateConfiguration(configuration, getBaseContext().getResources().getDisplayMetrics());
    //save data to shared preferences
    SharedPreferences.Editor editor = getSharedPreferences("Settings", MODE_PRIVATE).edit();
    editor.putString("My_Lang",lang);
    editor.apply();
}

//load saved lanuage in saved preferences
public void loadLocale(){
    SharedPreferences prefs = getSharedPreferences("Settings",Activity.MODE_PRIVATE);
    String language = prefs.getString("My_Lang","");
    setLocale(language);
}

What could be the problem?

Could you please add your ListView adapter code? – Rajnish suryavanshi Oct 17 '19 at 09:59 — Rajnish suryavanshi, Oct 17 '19 at 09:59

You probably need to call notifyDataSetChanged() on your list to force it to refresh the views within

@TinovimbaMawoyo why is that and do you have a better guess? – Sean Oct 17 '19 at 09:21
@DwayneT wherever you apply the language change – Ivan Wooll Oct 17 '19 at 09:34
@Sean i follewed a tuturiol so i'm not sure exactly where, is it after getBaseContext().getResources().updateConfiguration(configuration, getBaseContext().getResources().getDisplayMetrics()); ? – Dwayne T Oct 17 '19 at 09:41
you need to call it on your list adapter... But actually I like better @Noah answer restarting the whole Activity... – Sean Oct 17 '19 at 12:36

Try compiling the app as an apk if you are compiling it as an aab. I had the same problem and it was resolved by using an apk before uploading it to playstore
