Needs to add an extra schema in root layout :
whatever:testType can be replaced with options from options tab for validation

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:whatever="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <!-- Some stuff -->

	<com.andreabaccega.widget.FormEditText
           whatever:testType="alpha"
           android:id="@+id/et_firstname"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           />    

    <!-- Some other stuff -->

</LinearLayout>

regexp: for custom regexp
numeric: for an only numeric field
alpha: for an alpha only field
alphaNumeric: guess what?
email: checks that the field is a valid email
creditCard: checks that the field contains a valid credit card using Luhn Algorithm
phone: checks that the field contains a valid phone number
domainName: checks that field contains a valid domain name
ipAddress: checks that the field contains a valid ip address
webUrl: checks that the field contains a valid url
personName: checks if the entered text is a person first or last name.
personFullName: checks if the entered value is a complete full name.
date: checks that the field is a valid date/datetime format ( if customFormat is set, checks with customFormat )
numericRange: checks that the field is a valid value between integers. (minNumber and maxNumber must be set)
floatNumericRange: checks that the field is a valid value between integers (but decimal values are allowed). (minNumber and maxNumber must be set)
nocheck: It does not check anything except the emptyness of the field.

You can customize them using the attributes

testErrorString used when the field does not pass the test
emptyErrorString used when the field is empty

<?xml version="1.0" encoding="utf-8"?>

           whatever:testType="alpha"
           whatever:emptyErrorString="@string/your_name_cannot_be_empty"
           whatever:testErrorString="@string/your_name_is_ugly"
           android:id="@+id/et_firstname"
           android:layout_width="match_parent"
