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"/>

Order inside the XML matters, at least to eclipse. Define your enum above (or inside) your declare-styleable... not below.

<attr name="quality">
    <enum name="Good" value="1" />
    <enum name="Better" value="2" />
    <enum name="Best" value="3" />
</attr>

<declare-styleable name="SquareView">
    <attr name="quality" />
</declare-styleable>

<declare-styleable name="CircleView">
    <attr name="quality" />
</declare-styleable>

I had a very long enum so I placed it at the end of my XML to improve readability. It would parse correctly but reject values in Design mode.
