AutoCompleteTextView not working after changing the Locale

Question

In here 'AutoCompleteTextView' loads country list from 'Locale' with following code.

   public static ArrayList getCountryList()
        {
            Locale[] locale = Locale.getAvailableLocales();
            ArrayList<String>countries = new ArrayList<String>();
            String country = "";
            for( Locale loc : locale ){
                country = loc.getDisplayCountry();
                if( country.length() > 0 && !countries.contains(country) ){

                    countries.add( country );
                }
            }

            if(Build.VERSION.SDK_INT<=Build.VERSION_CODES.LOLLIPOP){
                countries.add("Sri Lanka");
            }
            Collections.sort(countries, String.CASE_INSENSITIVE_ORDER);

            return countries;

        }



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

    countryAutoTextView.setAdapter(new ArrayAdapter<String>(this, R.layout.country_list_spinner_loader, getCountryList()));

    changeLanguageButton.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View view) {
            Locale locale = new Locale(language);
            Resources res = getResources();
            DisplayMetrics dm = res.getDisplayMetrics();
            Configuration conf = res.getConfiguration();
            conf.locale = locale;
            res.updateConfiguration(conf, dm);
            finish();
            Intent refresh = new Intent(this, MainActivity.class);
            startActivity(refresh);
      }
   });   

}

For English language it's working fine for all the Android versions. But after changing the 'Locale' language specially "Sinhala" and "Hindi" as per user preference 'AutoCompleteTextView' is not loading countries for Android Nougat(24) in real devices and also emulators.

Finally I monitor that issue with android 'Log cat' when debug-gable device has Android Nougat. That is, When 'Locale' language is English, 'Log cat' displays following and 'Auto complete text view' loaded correctly.

But, when 'Locale' language is "Sinhala" or "Hindi", above 'Logcat' lines are not displaying and nothing loaded to the 'Auto complete text view'.

is it only display problem or local data is not comming ? did you check in debugger. — Harshal Deshmukh, Jun 29 '18 at 07:30
@ Harshal Deshmukh Yes it's a display issue, getCountryList is not null @ countryAutoTextView.setAdapter(new ArrayAdapter(this, R.layout.country_list_spinner_loader, getCountryList())); and also this issue is occurred only for 'Sinhala' language. — Nuwan Withanage, Jun 29 '18 at 08:13
if you code contains any margin form left or right then it make to start and end — Harshal Deshmukh, Jun 29 '18 at 08:52
After several notes asking you to desist, you still need to read [Under what circumstances may I add “urgent” or other similar phrases to my question, in order to obtain faster answers?](//meta.stackoverflow.com/q/326569). Please refrain from adding this to your questions. — halfer, Jul 01 '18 at 10:48
Your code updates need to be in the question itself, and not in comments, where they are not particularly readable. I will try to put the question on hold for now, since it does not seem to contain an [mcve]. — halfer, Jul 01 '18 at 10:49
Are you struggling with understanding the comments above, Nuwan? **What problem are you having understanding that we don't take begging messages?** — halfer, Jul 03 '18 at 12:15
add `android:completionThreshold="0"` to your `AutoCompleteTextView` xml — Rahul, Jul 03 '18 at 12:33
finally I myself solved the problem. The thing is I load the country list from 'Locale []'. after changing the device language by using 'Locale' that country list set meaningless values, then 'AutoCompleteTextView' loading that false values. For solve this issue I change the loading of country list method. Anyway thankz all to help me. — Nuwan Withanage, Jul 04 '18 at 04:32

For loading country list for 'AutoCompleteTextView'.

final ArrayAdapter<String>adapter = new ArrayAdapter<String>(this, R.layout.country_list_spinner_loader, DataLists.getCountryList());
        countryAutoTextView.setAdapter(adapter);

        adapter.registerDataSetObserver(new DataSetObserver() {
            @Override
            public void onChanged() {
                super.onChanged();
                Log.d("MAIN_COUNTRY_ADAPTER", "dataset changed");
                Object item = adapter.getItem(0);

                Log.d("MAIN_COUNTRY_ADAPTER", "item.toString "+ item.toString());
            }
        });

Instead of following method I used Hard coded countries for the list.

public static ArrayList getCountryList()
    {
        Locale[] locale = Locale.getAvailableLocales();
        ArrayList<String>countries = new ArrayList<String>();
        String country = "";
        for( Locale loc : locale ){
            country = loc.getDisplayCountry();
           if( country.length() > 0 && !countries.contains(country) ){

               countries.add( country );            
           }
        }

       if(Build.VERSION.SDK_INT<=Build.VERSION_CODES.LOLLIPOP){
            countries.add("Sri Lanka");
        }
       Collections.sort(countries, String.CASE_INSENSITIVE_ORDER);

       Log.d("DATA_LIST_CLASS", "COUNTRIES_LIST_SIZE_IS: " + countries.size() + countries.get(0) + countries.get(1));

        return countries;
    }

Because this also used 'Locale' to load the countries. It is an issue for changing device language and load the 'AutoCompleteTextView'.
