    <p>I wrote a library that extends EditText which supports natively some validation methods and is actually very flexible. </p> <p>Current, as I write, <strong>natively</strong> supported (through <strong>xml attributes</strong>) validation methods are:</p> <ol> <li><strong>regexp</strong>: for custom regexp</li> <li><strong>numeric</strong>: for an only numeric field</li> <li><strong>alpha</strong>: for an alpha only field</li> <li><strong>alphaNumeric</strong>: guess what?</li> <li><strong>email</strong>: checks that the field is a valid email</li> <li><strong>creditCard</strong>: checks that the field contains a valid credit card using Luhn Algorithm</li> <li><strong>phone</strong>: checks that the field contains a valid phone number</li> <li><strong>domainName</strong>: checks that field contains a valid domain name ( always passes the test in API Level &lt; 8 )</li> <li><strong>ipAddress</strong>: checks that the field contains a valid ip address webUrl: checks that the field contains a valid url ( always passes the test in API Level &lt; 8 )</li> <li><strong>nocheck</strong>: It does not check anything. (Default)</li> </ol> <p>You can check it out here: <a href="https://github.com/vekexasia/android-form-edittext" rel="noreferrer">https://github.com/vekexasia/android-form-edittext</a> </p> <p>Hope you enjoy it :)</p> <p>In the page I linked you'll be able to find also an example for email validation. I'll copy the relative snippet here:</p> <pre><code>&lt;com.andreabaccega.widget.FormEditText style="@android:style/Widget.EditText" whatever:test="email" android:id="@+id/et_email" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="@string/hint_email" android:inputType="textEmailAddress" /&gt; </code></pre> <p>There is also a test app showcasing the library possibilities.</p> <p>This is a screenshot of the app validating the email field.</p> <p><img src="https://i.stack.imgur.com/KtLb1.jpg" alt="email validation done thorugh xml+library"></p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
