Workflow custom animation question - trigger animation start

I've implemented following workflow to start animations as soon as my view is ready:

* I've sub classed an `RecyclerView` adapter for the simple reason of adding the ability to add a custom listener like following:

public interface IDataReadyListener
{
void onDataReady();
}
* I attach an empty adapter to my `RecyclerView` when the controller is created, so that an adapter is always attached to the `RecyclerView`
* I use the interface to start my animation at an arbitrary point that is not related to any view "lifecycle" event like `onPreDraw` or `onGlobalLayout` or similar... I manually notify the listener somewhere else when I know all items that are needed for the animation are ready. I need this, because my animation can only start as soon as some views of the `RecyclerView` have finished inflating AND have finished loading their images.

This works, but it looks ugly. It forces me to use a custom view (because the `ChangeHandler` only get's the from and the to `View` and I must use something offered by those `Views`).

Is there any more beautiful way to do that? Or is this really the default way and wanted so by design?
I think something like following would look nicer:

* access the controller from within my `ChangeHandler` and register my listeners in the controller (currently I can't access the controller from within the `ChangeHandler`, can I?)
* my adapter could notifiy the animation listener via the controller then and tell the listener that it is ready now

**I think it would really make sense to pass on the controllers to `ChangeHandler.performChange` so that the controllers can be used inside the `ChangeHandler`. Does anything speak against this?**
