Using Enums as Custom XML Attributes

Ex :

<attr name="myProperty" format="enum">
         <enum name="None" value="0"/>
         <enum name="One" value="1"/>
         <enum name="Two" value="2"/>
         <enum name="Three" value="3"/>
</attr>

Use like this:

<YourCustomView
    ...
    app:myProperty="One"/>
