假设我们的金额为12345.67美元
这可以使用joda货币库转换为货币价值,带有:
Money parsed = Money.parse("USD 12345.67");
//Now to display the amount according to the users locale we use:
MoneyFormatter mf = MoneyFormatterBuilder().appendAmountLocalized().toFormatter();
String localeString = mf.withLocale(Locale.getDefault()).print(parsed);
//Now assume the user is for example in Europe so the locale string would be 12.345,46
//Now assume he changes the amount inside a textfield to 12.345,47
Money changed = /*parse 12.345,47 (USD)*/
问题是我如何将本地化的String解析回货币值(注意分组数字是一个点,带的小数是一个逗号(。这还必须处理来自上面格式化程序的每个money值和每个字符串。
Money.parse()
仅适用于不满足[+-]?[0-9]*[.]?[0-9]*
要求的正则表达式
好的。明白了。你可以使用MoneyFormatter,反之亦然。文件有点不清楚
MoneyFormatter mf = MoneyFormatterBuilder().appendAmountLocalized().toFormatter()
MoneyParseContext parsed = mf.withLocale(Locale.getDefault()).parse(amount,0);
parsed.setCurrency(currency);
Money money = Money.of(parsed.toBigMoney());
