Class PhotoViewAttacher

java.lang.Object

com.github.chrisbanes.photoview.PhotoViewAttacher

All Implemented Interfaces:

android.view.View.OnLayoutChangeListener, android.view.View.OnTouchListener

public class PhotoViewAttacher
extends java.lang.Object
implements android.view.View.OnTouchListener, android.view.View.OnLayoutChangeListener

The component of PhotoView which does the work allowing for zooming, scaling, panning, etc. It is made public in case you need to subclass something other than AppCompatImageView and still gain the functionality that PhotoView offers
