Question

我如何使用＆＃34; R＆＃34;当语言环境设置为南非时的货币？

目前它显示＆＃34; ZAR＆＃34;我需要它来展示＆＃34; R＆＃34;代替。

我试过了：

final Currency curr = Currency.getInstance("ZAR");
final NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.getDefault());
nf.setCurrency(curr);
final String value = nf.format(12345.67);

然后一旦完成所有这些，我用R using.replace（）;

替换了ZAR

Answer 1

NumberFormat类根据作为参数传递的区域设置来格式化数字。如果该区域设置适用于南非（new Locale("en", "ZA")），则该数字将正确显示：R 12,345.67

final Currency curr = Currency.getInstance("ZAR");
final NumberFormat nf = NumberFormat.getCurrencyInstance(new Locale("en", "ZA"));
nf.setCurrency(curr);
final String value = nf.format(12345.67);
System.out.println(value);

Answer 2

构建自己的NumberFormat类（扩展Java），并实现自己的format版本;为ZAR以外的所有货币调用基类函数。

您目前采用的方法往往会导致大量重复（和未封装的）代码。

好的，我发现了一个很好的例子：

      public static SortedMap<Currency, Locale> currencyLocaleMap;
  static {
    currencyLocaleMap = new TreeMap<Currency, Locale>(new Comparator<Currency>() {
      public int compare(Currency c1, Currency c2){
        return c1.getCurrencyCode().compareTo(c2.getCurrencyCode());
      }
    });
    for (Locale locale : Locale.getAvailableLocales()) {
      try {
        Currency currency = Currency.getInstance(locale);
        currencyLocaleMap.put(currency, locale);
      }catch (Exception e){
      }
    }
  }

  public static String getCurrencySymbol(String currencyCode) {
    Currency currency = Currency.getInstance(currencyCode);
    System.out.println( currencyCode+ ":-" + currency.getSymbol(currencyLocaleMap.get(currency)));
    return currency.getSymbol(currencyLocaleMap.get(currency));
  }

从这里开始：Not getting currency symbols for specific Locale

使用＆＃34; R＆＃34;而不是＆＃34; ZAR＆＃34;对于南非货币
