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?

Don't know if you found what you were looking for, but I ended up writing a little method that takes the length of a string (since the phone numbers I get come from a web service and can be a variety of formats). I believe it should work (so far all my test cases have been with the first two options -- haven't tested the other two yet).

public static String FormatStringAsPhoneNumber(String input) {
    String output;
    switch (input.length()) {
        case 7:
            output = String.format("%s-%s", input.substring(0,3), input.substring(3,7));
            break;
        case 10:
            output = String.format("(%s) %s-%s", input.substring(0,3), input.substring(3,6), input.substring(6,10));
            break;
        case 11:
            output = String.format("%s (%s) %s-%s", input.substring(0,1) ,input.substring(1,4), input.substring(4,7), input.substring(7,11));
            break;
        case 12:
            output = String.format("+%s (%s) %s-%s", input.substring(0,2) ,input.substring(2,5), input.substring(5,8), input.substring(8,12));
            break;
        default:
            return null;
    }
    return output;
}

If you have the String "888-555-1234" - by using PhoneNumberUtils.formatNumber(numStr); you can simply do this:

String numStr = "888-555-1234";

numStr = "(" + numStr.substring(0,3) + ") " + numStr.substring(4);

System.out.print(numStr); // (888) 555-1234

However, this is hard coded. You would need to make sure the String had a full 10 digits before doing so.
