Phone number formatting an EditText in Android

There is a library called PhoneNumberUtils that can help you to cope with phone number conversions and comparisons. For instance, use ...

EditText text = (EditText) findViewById(R.id.editTextId);
PhoneNumberUtils.formatNumber(text.getText().toString())

... to format your number in a standard format.

PhoneNumberUtils.compare(String a, String b);

... helps with fuzzy comparisons. There are lots more. Check out http://developer.android.com/reference/android/telephony/PhoneNumberUtils.html for more.

p.s. setting the the EditText to phone is already a good choice; eventually it might be helpful to add digits e.g. in your layout it looks as ...

<EditText
    android:id="@+id/editTextId"
    android:inputType="phone"
    android:digits="0123456789+" 
/> 

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.
