I am trying to implement the Flip card transition effect between two activities in my app by taking help from : http://blog.robert-heim.de/karriere/android-startactivity-rotate-3d-animation-activityswitcher/.
But I couldn't understand what areActivitySwitcher.java and Roatate3dAnimation.java in the above mentioned site. I have two activities in my app between whom I want to show this transition effect. They are MainActivity.java and About_us.java.
Please explain the code with reference to my activities. I also searched on http://developer.android.com/training/animation/cardflip.html but in vain as it not for activities. Thanks!

推荐答案

有这样做，我发现了一个非常简单的方法。首先，确保你有一个在你的资源文件夹，您的项目称为动画的文件夹。然后，你需要创建两个XML文件（我有我叫from_middle和to_middle）。下面是code为每个的：

There is a very simple way of doing this that I have found. First, make sure that you have a folder called anim under your res folder for your project. Then you will need to create two xml files (I have mine called from_middle and to_middle). Below is the code for each of those:

from_middle.xml：

from_middle.xml:

<?xml version="1.0" encoding="utf-8"?>
<scale
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXScale="0.0" android:toXScale="1.0"
    android:pivotX="50%" 
    android:fromYScale="1.0" android:toYScale="1.0"
    android:pivotY="50%"         
    android:duration="500" />

to_middle.xml：

to_middle.xml:

<?xml version="1.0" encoding="utf-8"?>
<scale
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXScale="1.0" android:toXScale="0.0"
    android:pivotX="50%" 
    android:fromYScale="1.0" android:toYScale="1.0"
    android:pivotY="50%"        
    android:duration="500" />

这些被创建后，所有你需要的是一行code来运行这个动画，您应该放在你开始你的下一个活动后：

After those are created, all you need is one line of code to run this animation, which you should be placed after you start your next activity:

overridePendingTransition(R.anim.from_middle, R.anim.to_middle);

运行它，你应该看到预期的效果！

Run it, and you should see the desired results!
