問題描述

我在獲取系統的默認貨幣符號時遇到了一些問題.我以這種方式獲取貨幣符號:

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());

當系統語言為英語(美國)時，右側的符號會顯示($).但是當我選擇語言 Portuguese (Portugal) 它返回這個符號 ¤.

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 ¤.

這是什么原因造成的?

推薦答案

這似乎是一個已知問題(http://code.google.com/p/android/issues/detail?id=38622.我通過這種方式得出了一個可能的解決方案:

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:

由于問題出在符號而不是貨幣代碼中，我解決了這個問題，創建了一個靜態Map，其中鍵是 CurrencyCode，值是 符號.

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","$");
            (..)
        }
};

為了獲取語言環境信息中可用的所有(或幾乎)貨幣代碼，您可以執行以下操作:

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
  }
}

使用 CurrencyCode 和 Symbol 創建地圖后，您只需要這樣:

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());
