Usage

Adding EmailValidationEditText

The EmailValidationEditText class is a pre-built EditText subclass that will automatically validate its own input when it loses focus (such as when the user goes from the email field to the password field). If a syntax error is detected, a popup will appear informing the user that the email address they entered is invalid. If a probably typo is detected, a popup will appear that allows the user to accept the suggestion or dismiss the popup. The first thing you need to do is add this view to your layout XML:

<RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
        
        <com.spothero.emailvalidator.EmailValidationEditText
            android:id="@+id/et_email"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/email"
            android:imeOptions="actionNext"
            />
            
		<EditText
            android:id="@+id/et_password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/et_email"
            android:hint="@string/password"
            android:inputType="textPassword"
            android:imeOptions="actionDone|flagNoExtractUi|flagNoFullscreen"
            />
            
</RelativeLayout>

###Customization EmailValidationEditText can be customized in its look and feel as well as the error messages it will display. The following XML attributes are available (note that these using these XML attributes requires a valid namespace. For example, put xmlns:custom="http://schemas.android.com/apk/res-auto" in your top-level XML tag, then prefix the following attributes with custom:):

popupBorderColor: The color of the popup's border

popupFillColor: The fill color of the popup

popupTitleColor: The color of the popup's title text

popupSuggestionColor: The color of the email address suggestion text

popupDismissButtonColor: The color of the X displayed to the right of the popup

suggestionTitle: The title that appears with a suggestion (defaults to "Did you mean")

defaultErrorMessage: The default message that will appear on syntax errors (defaults to "Please enter a valid email address")

invalidSyntaxError: The message that appears on syntax errors (defaults to the contents of defaultErrorMessage)

invalidUsernameError: The message that appears when the username portion of the email address contains an error (defaults to the contents of defaultErrorMessage)

invalidDomainError: The message that appears when the domain portion of the email address contains an error (defaults to the contents of defaultErrorMessage)

invalidTLDError: The message that appears when the TLD portion of the email address contains an error (defaults to the contents of defaultErrorMessage)
