Java 更改区域设置后AutoCompleteTextView不工作

在这里，“AutoCompleteTextView”使用以下代码从“Locale”加载国家/地区列表

   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);
      }
   });   

}

但是，当“Locale”语言为“Sinhala”或“Hindi”时，上面的“Logcat”行不会显示，也不会加载任何内容到“自动完成文本视图”。

用于加载“自动完成文本视图”的国家/地区列表

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());
            }
        });

final ArrayAdapteradapter=新的ArrayAdapter（这个，R.layout.country_list_微调器_加载器，DataLists.getCountryList（））；
countryAutoTextView.setAdapter（适配器）；
registerDataSetObserver（新的DataSetObserver（）{
@凌驾
更改后的公共无效（）{
super.onChanged（）；
Log.d（“主要国家/地区适配器”，“数据集已更改”）；
对象项=适配器.getItem（0）；
Log.d（“主适配器”，“item.toString”+item.toString（））；
}
});

我用硬编码的国家来代替下面的方法

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;
    }

publicstaticarraylistgetcountrylist（）
{
Locale[]Locale=Locale.getAvailableLocales（）；
ArrayListcountries=新的ArrayList（）；
字符串country=“”；
for（Locale loc:Locale）{
country=loc.getDisplayCountry（）；
if（country.length（）>0&&！countries.contains（country））{
国家。添加（国家）；
}
}
如果（Build.VERSION.SDK）仅显示问题或本地数据未提交？是否签入调试器。@Harshal Deshmukh是的，这是一个显示问题，getCountryList不为null@countryAutoTextView.setAdapter（新ArrayAdapter（此，R.layout.country\u列表\微调器\加载器，getCountryList（））；而且此问题仅适用于“僧伽罗”语言。然后将xml文件代码添加到此处Country_list_spinner_loader和
