Phone number formatting an EditText in Android

Simply use the PhoneNumberFormattingTextWatcher, just call:

editText.addTextChangedListener(new PhoneNumberFormattingTextWatcher());

Addition
To be clear, PhoneNumberFormattingTextWatcher’s backbone is the PhoneNumberUtils class. The difference is the TextWatcher maintains the EditText while you must call PhoneNumberUtils.formatNumber() every time you change its contents.
