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.
