Formatting Phone Number in Android

Question

I tried the following code to format phone number in android:-

public static String formatPhoneNumber(String number){

        return PhoneNumberUtils.formatNumber(number);
    }

I am passing "19253951646" to the function.. It returns the text in the format 1-925-395-1646. I want the result in the format 1(925)395-1646. Any help would be highly apprciated.

Answer 1

Wrote my own function to format the number.

public static String formatPhoneNumber(String number){  
        number  =   number.substring(0, number.length()-4) + "-" + number.substring(number.length()-4, number.length());
        number  =   number.substring(0,number.length()-8)+")"+number.substring(number.length()-8,number.length());
        number  =   number.substring(0, number.length()-12)+"("+number.substring(number.length()-12, number.length());
        return number;
    }

Answer 2

Android SDKs PhoneNumberUtils has more or less adequate phone number formatting utils but sometimes it might not be enough for special needs.

Try out alternative library libphonenumber described as "Google's common Java, C++ and JavaScript library for parsing, formatting, storing and validating international phone numbers. The Java version is optimized for running on smartphones, and is used by the Android framework since 4.0 (Ice Cream Sandwich)."

The library has different phone number formatting options.

This is my code and this run without error:

    mobile.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void afterTextChanged(Editable editable) {
            StringBuilder digits = new StringBuilder();
            StringBuilder phone = new StringBuilder();
            char[] chars = mobile.getText().toString().toCharArray();


            for (int x = 0; x < chars.length; x++) {
                if (Character.isDigit(chars[x])) {
                    digits.append(chars[x]);
                }
            }

            //Format for 6 digits and below
            if (digits.toString().length() >= 6) {
                String six = new String();
                six += digits.toString();
                phone.append(six);
                //Format for 7 digits 
                if (digits.toString().length() >= 7) {
                    phone.setLength(0);
                    String countryCode = new String();
                    countryCode += digits.toString().substring(0, 3) + "-";
                    countryCode += digits.toString().substring(3,7);

                    phone.append(countryCode);
                    //Format for 8 and 9 digits
                    if (digits.toString().length() >= 8) {
                        phone.setLength(0);
                        String eight = new String();
                        eight += digits.toString();
                        phone.append(eight);
                        //Format for 10 digits
                        if (digits.toString().length() >= 10) {
                            phone.setLength(0);

                            String regionCode = new String();

                            regionCode += "(" + digits.toString().substring(0, 3) + ") ";
                            regionCode += digits.toString().substring(3, 6) + "-";

                            phone.append(regionCode);
                            //Format for 11 digits
                            if (digits.toString().length() >= 11) {
                                String code = new String();
                                phone.setLength(0);
                                code += digits.toString().substring(0, 1);
                                code += "(" + digits.toString().substring(1, 4) + ")- ";
                                code += digits.toString().substring(4, 7) + "-";
                                code += digits.toString().substring(7, 11);
                                phone.append(code);
                                //Format for 12 digits
                                if (digits.toString().length() >= 12) {
                                    String newCode = new String();
                                    phone.setLength(0);
                                    newCode += "+" + digits.toString().substring(0, 2);
                                    newCode += "(" + digits.toString().substring(2, 5) + ")";
                                    newCode += digits.toString().substring(5, 8) + "-";
                                    newCode += digits.toString().substring(8, 12);

                                    phone.append(newCode);
                                    //Format for 12 digits and more
                                    if (digits.toString().length() >= 13) {
                                        String noMoreThanTwelve = new String();
                                        phone.setLength(0);
                                        noMoreThanTwelve += digits.toString();
                                        phone.append(noMoreThanTwelve);
                                    }
                                }
                            } else {
                                phone.append(digits.toString().substring(6));
                            }
                        }
                    }
                }
                mobile.removeTextChangedListener(this);
                mobile.setText(phone.toString());
                mobile.setSelection(mobile.getText().toString().length());
                mobile.addTextChangedListener(this);
            } else {
                return;
            }

        }
    });

This is the output of my code:

Below 7 digits: 123456 = 123456

7 Digits: 1234567 = 123-4567

8 Digits 12345678 = 12345678

9 Digits 123456789 = 123456789

10 Digits 1234567890 = (123) 456-7890

11 Digits 12345678901 = 1 (234) 567-8901

12 Digits 123456789012 = +12 (345) 678-9012

More than 12 Digits 12345678901234 ....

Sorry for using these variables but I do hope you understand my code.

1-925-395-1646

number have international USA format. If you want custom format, you can parse number manually and format him.

So, you can try insert +1 before number.
