For any other purpose, declaring a custom property in the XML file can be retrieve with attrs constructor parameter.

In my case I reuse a preference custom dialog, and set things like that:

Then in my class contructor:

public CustomView(Context context, AttributeSet attrs) {
    String bar = attrs.getAttributeValue(null, "foo");
    Log.d("CustomView", "foo=" + bar);
}
