推荐答案

如果您知道要使用的国家/地区，则可以使用Google的开放源代码库

If you know the country for which you want to do it, you can use Google's open source library libphonenumber . Here is how you can format it:

String numberStr = "8885551234"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
  PhoneNumber numberProto = phoneUtil.parse(numberStr, "US");
  //Since you know the country you can format it as follows:
  System.out.println(phoneUtil.format(numberProto, PhoneNumberFormat.NATIONAL));
} catch (NumberParseException e) {
  System.err.println("NumberParseException was thrown: " + e.toString());
}

如果您不知道国家/地区，则对于numberStr，请使用 E.164格式的电话号码并使用国家/地区代码代替null.

If you don't know the country then for numberStr use E.164 format phone number and in place of country code use null.
