You can use shape drawables (circles and lines) to define elements and then combine them in one drawable with Layer List. All this can be defined in XML.

There is no way to use xml, because i compute the radius of the circle inside java. What i have done so far is using a BitmapShader to repeat my lines. The problem is now, that the inner circle as this texture, too. So how can i make the inner circle transparent, so that my background image (google maps view) is visible again. – Robert Kornmesser Sep 12 '11 at 09:16
