Interface SubsamplingScaleImageView.OnStateChangedListener

  • All Implemented Interfaces:

    
    public interface SubsamplingScaleImageView.OnStateChangedListener
    
                        

    An event listener, allowing activities to be notified of pan and zoom events. Initialisation and calls made by your code do not trigger events; touch events and animations do. Methods in this listener will be called on the UI thread and may be called very frequently - your implementation should return quickly.
