All Implemented Interfaces:

android.view.View.OnLayoutChangeListener , android.view.View.OnTouchListener
```
public class PhotoViewAttacher
 implements View.OnTouchListener, 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
