Android under QQ space view big picture effect

Recently in a project, there is a function is to achieve the Android QQ friends dynamic inside thumbnail zoom, view the effect of large image. Used to know, this special effect is very good, useless download a play it. I just started thinking that the big picture that zoomed in was an activity or a dialog. But after trying to find out how also can not achieve that effect (with the realization of friends, please tell me, Exchange and Exchange). Then to the Android website found a picture amplification effect of the demo. This demo really is to achieve the QQ inside the image amplification of the basic effect, but the requirements of Android 3.0 or more talent, because the inside used to animator. I know there is a Nineoldandroids library implemented under 3.0 can also use animator, just to rewrite it again OK. But look at the big picture also has the pinch image scale, double-click Enlarges, the picture restores and so on the effect, but the general realization basically is realizes with the scaleanimation, the feeling effect is not ideal. Then on GitHub found a very good demo called android-gridview-zoom-images-animation-tutorial, which actually realized the QQ space thumbnail image amplification and restore animation effects. Looked under, also need to Android3.0 above talent realization, realize principle and official online that demo nearly identical. On GitHub stroll down, found a very good photoview, the two are basically QQ friends dynamic inside to achieve the special effects. The following are:

Thumbnail interface, click on each thumbnail, the image from the thumbnail location to zoom in to the screen to adapt to the location.

Ability to pinch zoom picture, double click to enlarge picture, click Picture Zoom back.

The ability to swipe the picture right or left to toggle the picture.

PS: The project source code is open source, address: Https://github.com/ywenblocker/Android-Photo-Zoom. Do you have any good tools for making GIF pictures under Mac? The pictures I sent are very difficult to express the animation effect.
