Doxygen Java multiple interfaces diagram

I'm trying to generate documentation for an Android projet with Doxygen.

I use Graphviz to generate a collaboration diagram, but I can't find how to have multiple interface in the graph!

public class ImageProcessing extends Activity implements OnClickListener, Camera.Prev开发者_Python百科iewCallback, SurfaceHolder.Callback {

With the previous class declaration, I obtain a graph with only Activity and first interface OnClickListener.

How can I declare that they must consider other interfaces too?

It works alright for me.

Maybe you need to select EXTRACT_ALL.
