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

Question

Can anybody help me to solve this problem ?

I want "-" between phone numbers. I tried . It shows XXX-XXX-XXX-X Formats only . But i want XXX-XXX-XXXX Format .

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;
    }

You best way to go is to use Regular Expressions .

You know your phone number should have the format XXX-XXX-XXXX , so you just write an appropriate RegEx for this, and you are fine!

用space (" ")格式化，然后替换所有的"-"字符。
