使用Java将电话号码转换为国际格式(E.164)的最佳方法是什么?
给定电话号码和国家/地区编号说ISO国家代码),我想把它转换成一个标准的E.164国际格式的电话号码。
我相信我可以用手很容易地做到这一点 - 但我不确定它会在所有情况下正常工作。
你会推荐哪一种Java框架/库/实用工具来完成这项工作?
$ b
PS 电话号码可以是一般公众可以识别的任何东西 - 例如
$ p code $ *(510)786-0404
* 1-800-GOT-MILK
* + 44-(0)800-7310658
<最后一个是我最喜欢的 - 这是一些人在英国写的号码,这意味着你应该使用+44或者你应该使用0。
< E.164格式的数字应该是全部的数字,并使用完整的国际国家代码(例如+44) Google提供了一个用于处理电话号码的库。他们用于Android的同一个

字符串swissNumberStr =044 668 18 00
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
尝试{
PhoneNumber swissNumberProto = phoneUtil.parse(swissNumberStr,CH);
} catch(NumberParseException e){
System.err.println(NumberParseException was thrown:+ e.toString());
}
//产生+41 44 668 18 00
System.out.println(phoneUtil.format(swissNumberProto,PhoneNumberFormat.INTERNATIONAL));
//生成044 668 18 00
System.out.println(phoneUtil.format(swissNumberProto,PhoneNumberFormat.NATIONAL));
//产生+41446681800
System.out.println(phoneUtil.format(swissNumberProto,PhoneNumberFormat.E164));
What is the best way for converting phone numbers into international format (E.164) using Java?
Given a 'phone number' and a country id (let's say an ISO country code), I would like to convert it into a standard E.164 international format phone number.
I am sure I can do it by hand quite easily - but I would not be sure it would work correctly in all situations.
Which Java framework/library/utility would you recommend to accomplish this?
P.S. The 'phone number' could be anything identifiable by the general public - such as
* (510) 786-0404
* 1-800-GOT-MILK
* +44-(0)800-7310658
that last one is my favourite - it is how some people write their number in the UK and means that you should either use the +44 or you should use the 0.
The E.164 format number should be all numeric, and use the full international country code (e.g.+44)
Google provides a library for working with phone numbers. The same one they use for Android
http://code.google.com/p/libphonenumber/
String swissNumberStr = "044 668 18 00"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
PhoneNumber swissNumberProto = phoneUtil.parse(swissNumberStr, "CH");
} catch (NumberParseException e) {
System.err.println("NumberParseException was thrown: " + e.toString());
}
// Produces "+41 44 668 18 00"
System.out.println(phoneUtil.format(swissNumberProto, PhoneNumberFormat.INTERNATIONAL));
// Produces "044 668 18 00"
System.out.println(phoneUtil.format(swissNumberProto, PhoneNumberFormat.NATIONAL));
// Produces "+41446681800"
System.out.println(phoneUtil.format(swissNumberProto, PhoneNumberFormat.E164));
