如何格式化与设备货币格式的浮点值？ [英] How to format a Float Value with the device currency format?

问题描述

我有打印计算货币价值的应用程序，我想显示默认货币格式值。

I have an app that prints a calculated money value and I want to display that value with the default currency format.

例如在欧洲你可以这样写：

For example in Europe you would write:

1.000,95€

在美国，我想你会写

1,000.95 $

1,000.95$

在其他货币的有或多或少的值显示为小数，在美国，它是2，但在日本，它是0。

In other currencies there are more or less values displayed for the decimal fraction, in US it would be 2 but in Japan it would be 0.

我怎样才能获得一个确切尽可能格式为所有现有货币？

How can I obtain a exact as possible format for all existing currencies?

推荐答案

我找到了解决办法。类的NumberFormat 有predefined格式化的，众说纷纭。还有一个用于格式化货币值。

I found the solution. THe class NumberFormat has a multitude of predefined formatters. There is also one for formatting currency Values.

如果您使用静态方法getCurrencyInstance类将返回一个格式化该设备的缺省货币。我用下面的code设置我的结果：

If you use the static method getCurrencyInstance the class will return a formatter for the device default currency. I use the following code to set my result:

NumberFormat format = NumberFormat.getCurrencyInstance();
((TextView) findViewById(R.id.text_result)).setText(format.format(result));
