Creates and returns an animation listener, which allows to hide the animated view once the
animation is finished.

@param animatedView
The animated view as an instance of the class {@link View}. The view may not be null
@param listener
The listener, which should be notified, as an instance of the type {@link
AnimatorListener} or null, if no listener should be notified
@return The animation listener, which has been created, as an instance of the type {@link
AnimatorListener}
