Question

我希望按货币名称获取货币符号（例如 $ 或£）（例如 USD 或 EUR ）。

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

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 4

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，如下所示。

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

这对我有用。

Answer 6

您可以简单地使用此代码来获取货币符号和不同的货币格式。这里变量“curr”将从用户那里获取输入值。然后将其转换为不同的货币格式及其符号。在本文中，我解释了 4 种货币格式。通过这种方式，您也可以使用其他国家/地区的格式。

import java.util.*;
import java.text.*;

public class CurrencyConvertor{
    
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double curr = scanner.nextDouble();
        scanner.close();
        if(curr>=0 && curr<=1000000000){
 NumberFormat france = NumberFormat.getCurrencyInstance(Locale.FRANCE);
NumberFormat us = NumberFormat.getCurrencyInstance(Locale.US);
NumberFormat china = NumberFormat.getCurrencyInstance(Locale.CHINA);
        NumberFormat india = NumberFormat.getCurrencyInstance(Locale.ENGLISH);
        
        

System.out.println("France: " + france.format(curr));
 System.out.println("US: " + us.format(curr));
         System.out.println("India: "+NumberFormat.getCurrencyInstance(new Locale("en","IN")).format(curr)); 
         System.out.println("China: "+ china.format(curr));
        
        }
    }
}

Answer 7

这是一个简单的解决方案。如上所述：

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

String symbol = currency.getSymbol();
