PhotoView aims to help produce an easily usable implementation of a zooming Android ImageView. It is currently being used in photup. Currently supports:
- Out of the box zooming, using multi-touch and double-tap.
- Scrolling, with smooth scrolling fling.
- Works perfectly when using used in a scrolling parent (such as ViewPager).
- Allows the application to be notified when the displayed Matrix has changed. Useful for when you need to update your UI based on the current zoom/scroll position.
- Allows the application to be notified when the user taps on the Photo.
