Zoomable Android image view

By default, an ImageView is not zoomable in an Android app by a finger touch. Just found a brilliant customization of Android's ImageView, which is zoomable. It's located here: https://github.com/MikeOrtiz/TouchImageView.

To use it in the app, we just have to do TouchImageView iv = (TouchImageView) findViewById(R.id.img); (in an Activity's onCreate method for example). Of course, TouchImageView supports all the behavior of standard ImageView class.
