如何使用语言环境获取特定国家/地区的货币符号？

Question

我已经尝试过这段代码，它给了我一些国家/地区的Country Code，而不是currency symbol

我想要的是货币符号而不是代码

数组资源列表包含所有国家及其代码

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

Currency 规范中说：

getSymbol() 获取默认语言环境下该货币的符号。 例如，对于美元，如果默认符号为“$” 语言环境是美国，而对于其他语言环境，它可能是“US$”。如果不 可以确定符号，返回ISO 4217货币代码。

已编辑 我找到了解决这个问题的方法

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;
    }
}

打印出来：

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 ￥
