Thanks guys, I have tested all this and almost achieved what I want. I
have change the code form Romain Guy a little bit so now I have:
<item>
<shape android:shape="oval">
<gradient
android:useLevel="true"
android:type="sweep"
android:startColor="#ff000000"
android:endColor="#ffffffff" />
</shape>
</item>
And this is almost what I want. I would like to change the eliminate
the gradient factor so the circle that is 'unfolding' has the same
colour all the time. If this is manageable then I guess I'm home :>
