对南非货币使用 "R" 而不是 "ZAR"

Question

当区域设置为南非时，如何使用 "R" 作为货币？

目前它显示 "ZAR"，我需要它显示 "R"。

我试过：

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

所有这些都完成后，我将 ZAR 替换为 R using.replace();

Answer 1

构建您自己的 NumberFormat class（扩展 Java），并实现您自己的 format 版本；为 ZAR.

以外的所有货币调用基础 class 函数

您当前采用的方法往往会导致大量重复（且未封装）代码。

Answer 2

好的，我找到了一个很好的例子：

      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

Answer 3

NumberFormat class 根据作为参数传递的语言环境格式化数字。如果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);

Use "R" instead of "ZAR" for South African Currency
