How To Create Phone Number Format XXX-XXX-XXXX In Android

+1 vote

Here Below I have mentioned my code.

Declare This under Oncreate

TextView TxtDocPhone=(TextView)findViewById(R.id.TxtDocPhone);

String numbersOnly = keepNumbersOnly(Phone);
String ProviderPhone = formatNumbersAsCode(numbersOnly);

Then call it

 private String keepNumbersOnly(CharSequence s) {
        return s.toString().replaceAll("[^0-9]", ""); 
    }

    private String formatNumbersAsCode(CharSequence s) {
        int groupDigits = 0;
        String tmp = "";
        for (int i = 0; i < s.length(); ++i) {
            tmp += s.charAt(i);
            ++groupDigits;
            if (groupDigits == 3) {
                tmp += "-";
                // tmp += "";
                groupDigits = 0;
            }
        }
        return tmp;
    }

Please guide me the correct way to achieve my objective.
