How to get currency symbol by currency name?

问题

I want get Currency symbol (like $ or £) by currency name (like USD or EUR).

For English(US) I can get symbol (if English(US) set as language on device):

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

How can I get symbol for currency by currency name using android tools -

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

You can try some like this:

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));
        }

    }
}

Currency symbol depends on location. The same $ sign means different currencies in US and Australia. So, to get the correct symbol you have to provide the Locale instance. Otherwise, a default locale will be applied, which will result in different values for different devices.

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

I've solved this problem to create a Map which has the key is the currency code and the value is the symbol.

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

Then, you can get the symbol by using Locale, like this.

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

回答4:

I believe java.util.currency is the class you need, call getSymbol to get symbol from currency name

回答5:

This works for me.

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

回答6:

Here is a simple solution. As said above:

Currency currency = Currency.getInstance("INR");

String symbol = currency.getSymbol();
