Supposing that you wanna format the phone number as per US format.

+1 (###) ###-####,1 (###) ###-####,###-####,###-###-####,011 $

The following will serve your purpose:

phoneEditText.addTextChangedListener(new TextWatcher() {
    private boolean mFormatting; // a flag that prevents stack overflows.
    private int mAfter;

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) { 
    }

    //called before the text is changed...
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        mAfter = after; // flag to detect backspace.
    }

    @Override
    public void afterTextChanged(Editable s) {
    // Make sure to ignore calls to afterTextChanged caused by the work done below
        if (!mFormatting) {
            mFormatting = true;
            // using US formatting.
            if(mAfter != 0) // in case back space ain't clicked.
                PhoneNumberUtils.formatNumber(
                    s,PhoneNumberUtils.getFormatTypeForLocale(Locale.US));
            mFormatting = false;
        }
    }
});

If you need location specific services, i.e. for each location, you need specific format of that place (refer to this link). If you need only the format you needed, then write a custom function in the place of line in the above code snippet.

PhoneNumberUtils.formatNumber(
    s, PhoneNumberUtils.getFormatTypeForLocale(Locale.US));
