For non-NANP (http://www.howtocallabroad.com/nanp.html) countries to implement phone number formatting while user typing, you can use some workaround like this:

yourEditText.addTextChangedListener(new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

                String typedNum = yourEditText.getText().toString();
                if(typedNum.length() == 3)
                {
                    yourEditText.setText(typedNum + "-");
                yourEditText.setSelection(4);
                }
                else if(typedNum.length() == 7)
                {
                    yourEditText.setText(typedNum + "-");
                    yourEditText.setSelection(8);
                }

            }
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
            }
            @Override
            public void afterTextChanged(Editable s) {
            }
        });

Otherwise solution can be :

import android.telephony.PhoneNumberFormattingTextWatcher;

OnCreate :

yourEditText.addTextChangedListener(new PhoneNumberFormattingTextWatcher());

If you like to format the number after user has entered the phone number:

  import android.telephony.PhoneNumberUtils;

OnCreate :

PhoneNumberUtils.formatNumber(Editable text, int defaultFormattingType);
