Android adds animation transitions for Viewpager

In the development of Android application, Viewpager can achieve a lot of beautiful switching functions, such as banner unlimited ads scroll bar, novice boot, etc. are used to get, the use of the frequency is self-evident. Rely on Google to provide the auxiliary code, Viewpager switch effect can be more brilliant, the implementation process is quite simple.

First in the browser to enter the URL provided by Google, links such as: http://developer.android.com/training/animation/screen-slide.html, if not smooth open, you'd better prepare a circumvention tool, keep the requirements.

In the site you can see some of the Viewpager animation, as well as the corresponding animation to implement the source code.

Take Zoomoutpagetransformer as an example, as long as you copy the code that corresponds to the animation effect class to your project, you can use it directly. In particular, this feature is only applicable to android3.0 above, but with 3.0 of the mobile phone gradually fade out of the market, I think in the near future, you just need to consider the 4.0 and above models.

The latest statistics show that less than 3% active users below android4.0, of course, if you encounter a slightly harsh product manager, perseverance under 3.0 users, can also find the corresponding open source project to be compatible with the low version, is more tired.

The introduction of animations to the Viewpager implementation code is quite simple, altogether in this sentence:

Mviewpager.setpagetransformer (True, New Zoomoutpagetransformer ());
