SimpleOnScaleGestureListener 2.4.2 API

All Implemented Interfaces:

com.flyjingfish.openimagelib.photoview.ScaleGestureDetector.OnScaleGestureListener
```
public class ScaleGestureDetector.SimpleOnScaleGestureListener
 implements ScaleGestureDetector.OnScaleGestureListener
                    
```
A convenience class to extend when you only want to listen for a subsetof scaling-related events. This implements all methods in OnScaleGestureListener but does nothing. onScale returns {@code false} so that a subclass can retrieve the accumulated scalefactor in an overridden onScaleEnd. onScaleBegin returns {@code true}.

  - onScale
```
 boolean onScale(ScaleGestureDetector detector)
```
    Responds to scaling events for a gesture in progress.Reported by pointer motion.
    
    Parameters:
    
    detector - The detector reporting the event - use this toretrieve extended info about event state.
  - onScaleBegin
```
 boolean onScaleBegin(ScaleGestureDetector detector)
```
    Responds to the beginning of a scaling gesture. Reported bynew pointers going down.
    
    Parameters:
    
    detector - The detector reporting the event - use this toretrieve extended info about event state.
  - onScaleEnd
```
 void onScaleEnd(ScaleGestureDetector detector)
```
    Responds to the end of a scale gesture. Reported by existingpointers going up.Once a scale has ended, getFocusX and getFocusY will return focal pointof the pointers remaining on the screen.
    
    Parameters:
    
    detector - The detector reporting the event - use this toretrieve extended info about event state.
