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.

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.

You simply use this and get you want :

new PhoneNumberFormattingTextWatcher()

or Have look at this url :

Answer 5

Try to use regex. This will help you. As for me, i use this:

                        var result = "+1 888-555-1234"


                        if (Pattern.compile("^\\+[\\d]+\\s[\\d]{1,3}\\s[\\d]+").matcher(result).find()) {
                            result = result.replaceFirst(" ", "(").replaceFirst(" ", ")").replace(" ","-")
                        }

                        if(Pattern.compile("^\\+[\\d]+\\s[\\d]{1,3}-[\\d]+").matcher(result).find()){
                            result = result.replaceFirst(" ", "(").replaceFirst("-", ")")
                        }
                        Timber.d("$result")

output: +1(888)555-1234

Working solution in 2020:

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

String countryIso = telephonyManager.getNetworkCountryIso().toUpperCase();

phoneNumberTextView.setText(PhoneNumberUtils.formatNumber("3473214567", countryIso));
