如何通过货币名称获取货币符号？

Question

我想通过货币名称（如 USD 或 EUR ）获取货币符号（如 $ 或 £ ）。

对于英语（美国）我可以获得符号（如果英语（美国）设置为设备上的语言）：

 Currency currency = Currency.getInstance(Locale.getDefault());
String symbol = currency.getSymbol()); // $

如何使用 Android 工具按货币名称获取货币符号 -

 someMethod (String currCode) { // currCode - USD, EUR, UAH
    return currSymbol;       // $...
}

你可以试试这样的：

 public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Utils.getCurrencySymbol(Currency.getInstance(Locale.US).getCurrencyCode());
        Utils.getCurrencySymbol(Currency.getInstance(Locale.JAPAN).getCurrencyCode());
        Utils.getCurrencySymbol(Currency.getInstance(Locale.UK).getCurrencyCode());

        //for your case that you want to get Euro symbol because France are with Euro symnol
        Utils.getCurrencySymbol(Currency.getInstance(Locale.FRANCE).getCurrencyCode());
        //you can get symbol also if you write string of your desired currency
        Utils.getCurrencySymbol("INR");

    }

    static class Utils {
        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));
        }

    }
}

货币符号取决于位置。相同的 $ 符号在美国和澳大利亚表示不同的货币。因此，要获得正确的符号，您必须提供 Locale 实例。否则，将应用默认区域设置，这将导致不同设备的不同值。

     Locale uk = new Locale("en", "GB");
    Currency pound = Currency.getInstance("GBP");
    pound.getSymbol(uk);
