我下面这个教程的使用ViewPager的屏幕幻灯片的 http://developer.android.com/training/animation/screen-slide.html 但我有问题。换句话说，我想实现ViewPager.PageTransform但这接口不存在，如图像所示。

I'm following this tutorial Using ViewPager for Screen Slides http://developer.android.com/training/animation/screen-slide.html but I've problem. In other words, I want to implement ViewPager.PageTransform but this interface doesn't exist, like image shows.

我把V13支持库和minTarget为14。

I put v13 support library and minTarget is 14.

推荐答案

只需键入PageTransformer而不是ViewPager。然后尝试按Ctrl + Shift + O：）

Just type "PageTransformer" rather than "ViewPager." Then try Ctrl + Shift + O :)
