在这里，“ AutoCompleteTextView”使用以下代码从“ Locale”加载国家列表。
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);
}
});
}

对于英语，它适用于所有Android版本。但是在根据用户喜好特别更改了“语言环境”语言“ Sinhala”和“ Hindi”之后，“ AutoCompleteTextView”未在实际设备和仿真器中加载Android Nougat（24）的国家/地区。
最后，当可调试山墙设备具有Android Nougat时，我会监视android'Log cat'的问题。也就是说，当“语言环境”语言为英语时，将显示“日志猫”，并正确加载“自动完成文本视图”。

但是，当“区域设置”语言为“僧伽罗语”或“印地语”时，“ Logcat”行上方将不会显示，并且不会将任何内容加载到“自动完成文本视图”中。
答案 0 :(得分：0)
用于加载“ AutoCompleteTextView”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());
}
});
我使用硬编码国家/地区来代替列表。
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);
Log.d("DATA_LIST_CLASS", "COUNTRIES_LIST_SIZE_IS: " + countries.size() + countries.get(0) + countries.get(1));
return countries;
}
因为这也使用“语言环境”来加载国家/地区。更改设备语言并加载“ AutoCompleteTextView”是一个问题。
