获取一国货币code [英] Acquiring a country's currency code

问题描述

我有一个问题让一国货币code。我的任务是获取用户的位置，发现他是哪个国家，现在和得到这个国家的货币code。这里的code表示取国名和国家code从所获取的位置：

I have a problem getting a country's currency code. My task is to get the user's location, find out what country he is right now and get this country's currency code. Here's the code that fetches the country name and country code from the acquired location:

Geocoder gc = new Geocoder(this);
List<Address> addresses = gc.getFromLocation(
                location.getLatitude(), location.getLongitude(), 5);

textView1.setText(addresses.get(0).getCountryName());
textView2.setText(addresses.get(0).getCountryCode());

这工作完全正常。现在，我应该使用 java.util.Currency中类来获得一个货币对象。我可以使用 Currency.getInstance（区域设置区域）方法。但是，有一个在区域设置类没有构造函数，只允许该国code被作为参数传递。意味着我不能创建一个为国家语言环境对象。这又如何解决呢？提前致谢。

This works perfectly fine. Now I should use the java.util.Currency class to get a Currency object. I can use the Currency.getInstance(Locale locale) method. But there's no constructor in the Locale class that allows only the country code to be passed as an argument. Means I am not able to create a Locale object for the country. How can this be solved? Thanks in advance.

推荐答案

您应该可以使用 Currency.getInstance（新的语言环境（，code）），有可能的例外，如果该国code是无效的。

You should be able to use Currency.getInstance(new Locale("",code)), with a possible Exception if the country code isn't valid.
