对于英语(美国)，我可以获取符号(如果在设备上将英语(美国)设置为语言):

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-

推荐答案

您可以尝试以下操作:

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));
        }

    }
}
