android: how do I format number as phone with parentheses

Question

I have a number that I need to format as a telephone number. If I do

 PhoneNumberUtils.formatNumber(numStr);

Then I get

888-555-1234

But what I need to get is

(888) 555-1234

How do I get the second one? Is there a standard android way?

Answer 1

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());
}

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