如何使用區域設置獲取特定國家/地區的貨幣符號？

Question

我曾嘗試此代碼，它給我的Country Code對一些國家，而不是currency symbol

我想貨幣符號而不是代碼

數組resourseList包含了所有的國家與它的代碼

String m= (String) Array.get(recourseList,i); 
        String[] ma=m.split(","); 
        Locale locale=new Locale("en", ma[1]); 
        Currency currency= Currency.getInstance(locale); 
        String symbol = currency.getSymbol(); 
        ((TextView) finalV.findViewById(R.id.currencySymbolid)).setText(symbol); 

Answer 1

它sa ys在Currency規範中：

getSymbol（）獲取此貨幣的默認語言環境的符號。 例如，對於美元，如果默認 區域設置爲美國，則符號爲「$」，而對於其他區域設置，則可以是「美元」。如果沒有確定 符號，則返回ISO 4217貨幣代碼。

EDITED 我已經找到一種方法解決此問題

import java.util.Currency; 
import java.util.HashMap; 
import java.util.Locale; 
import java.util.Map; 

public class CurrencyCode 
{ 

    public static void main() { 
     Map<Currency, Locale> map = getCurrencyLocaleMap(); 
     String [] countries = { "US", "CA", "MX", "GB", "DE", "PL", "RU", "JP", "CN" }; 

     for (String countryCode : countries) { 
      Locale locale = new Locale("EN",countryCode); 
      Currency currency = Currency.getInstance(locale); 
      String symbol = currency.getSymbol(map.get(currency)); 
      System.out.println("For country " + countryCode + ", currency symbol is " + symbol); 
     } 
    } 

    public static Map<Currency, Locale> getCurrencyLocaleMap() { 
     Map<Currency, Locale> map = new HashMap<>(); 
     for (Locale locale : Locale.getAvailableLocales()) { 
      try { 
      Currency currency = Currency.getInstance(locale); 
      map.put(currency, locale); 
      } 
      catch (Exception e){ 
      // skip strange locale 
      } 
     } 
     return map; 
    } 
} 

此打印：

For country US, currency symbol is $ 
For country CA, currency symbol is $ 
For country MX, currency symbol is $ 
For country GB, currency symbol is £ 
For country DE, currency symbol is € 
For country PL, currency symbol is zł 
For country RU, currency symbol is руб. 
For country SE, currency symbol is kr 
For country JP, currency symbol is ￥ 
For country CN, currency symbol is ￥
