I know it is possible to create custom UI element (by way of View or specific UI element extension). But is it possible to define new properties or attributes to newly created UI elements (I mean not inherited, but brand new to define some specific behavior I am not able to handle with default propertis or attributes)

e.g. element my custom element:

<com.tryout.myCustomElement
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="Element..."
   android:myCustomValue=<someValue>
/>

So is it possible to define MyCustomValue?

Thx
