Detailed explanation of image zooming implemented by Android custom ImageView

I think this custom ImageView is very easy to use and has good performance, so I took it out and shared it with you. Because I can't make GIF diagrams, it's difficult to post the project effect. Post the code

1. Project structure diagram

2.Compat.class

3.HackyViewPager.class

4.IScaleView.class

5.ScaleView

6. Scaleviewattacher is the most critical

7.ScrollerProxy

8.SDK16

9.VersionedGestureDetector

10.MainActivity

activity_ main.xml
