如何通过货币名称获取货币符号？

Question

我希望按货币名称(如美元或欧元)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)在设备上设置为语言):

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 -

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.同一美元符号表示美国和澳大利亚的货币不同.因此,要获取正确的符号,您必须提供Locale实例.否则,将应用默认语言环境,这将导致不同设备的值不同.

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

Answer 3

这对我有用。

Currency currency = Currency.getInstance("GBP");
String symbol = currency.getSymbol();

Answer 4

我相信java.util.currency是你需要的类,调用getSymbol从货币名称获取符号

Answer 5

我已经解决了这个问题,创建了一个Map,其中键是货币代码,值是符号.

public final Map<String, String> CURRENCIES= new HashMap<String, String>(){
        {
            put("EUR","€");
            put("USD","$");
            ...
        }
}; 

然后,您可以使用Locale获取符号,就像这样.

Currency currency = Currency.getInstance(Locale.getDefault());
String symbol = CURRENCIES.get(currency.getCurrencyCode());
