区域设置货币符号 [英] Locale Currency Symbol

问题描述

我有一些问题得到了系统的默认货币符号。 我得到的货币符号是这样的：

I having some problems getting the default currency symbol of the system. I am getting the currency symbol this way:

Currency currency = Currency.getInstance(Locale.getDefault());
Log.v("TAG",currency.getSymbol());

在系统语言是在英语（美国）右符号显示出来（$ <$ C C $>）。 但是，当我选择的语言葡萄牙语（葡萄牙）返回这个符号¤。

When the system language is in English (United States) the right symbol shows up ($). But when i choose the language Portuguese (Portugal) it returns this symbol ¤.

有什么可以导致此？

推荐答案

这似乎是一个已知的问题（<一href="http://$c$c.google.com/p/android/issues/detail?id=38622">http://$c$c.google.com/p/android/issues/detail?id=38622. 我来到了一个可能的解决方案是这样的：

This seems to be a known issue (http://code.google.com/p/android/issues/detail?id=38622. I came to a possible solution this way:

由于该问题是在符号，而不是货币code，我解决了这个问题，创建一个静态地图，其中的关键是的货币$ C $ç的和值是符号的。

Since the problem is in the Symbol and not the Currency code, i solved this problem creating a staticMap where the key is the CurrencyCode and the value is the Symbol.

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

为了让所有（或几乎）codeS提供的语言环境的信息，你可以做这样的事情的货币：

In order to get all (or almost) the currencies codes available in the locales information you can do something like this:

for (Locale ll: Locale.getAvailableLocales()){
    try {
       Currency a = Currency.getInstance(ll);
       Log.v("MyCurrency",a.getCurrencyCode()+"#"+a.getSymbol());
    }catch (Exception e){
       // when the locale is not supported
  }
}

在创建映射与货币code 和符号的你就必须是这样的：

After you created you Map with the CurrencyCode and Symbol you just have to something like this:

Currency currency = Currency.getInstance(Locale.getDefault());
String curSymbol = MYCURRENCIES.get(currency.getCurrencyCode());
