注意：在有的系统上不能用，不！知！道！为！什！么！

首先在res下建立anim目录，然后在anim目录里添加相应的动画资源，本文章添加了两个动画资源，如下：

zoomin.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/decelerate_interpolator">
    <scale android:fromXScale="0.1" android:toXScale="1.0"
           android:fromYScale="0.1" android:toYScale="1.0"
           android:pivotX="50%p" android:pivotY="50%p"
           android:duration="300" />
    <!-- 这里为了看到动画演示效果，把动画持续时间设为3秒 -->
    <alpha
        android:fromAlpha="0.1"
        android:toAlpha="1.0"
        android:duration="300" />
</set>

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android"

android:interpolator="@android:anim/decelerate_interpolator">

<scale android:fromXScale="0.1" android:toXScale="1.0"

android:fromYScale="0.1" android:toYScale="1.0"

android:pivotX="50%p" android:pivotY="50%p"

android:duration="300" />

<alpha

android:fromAlpha="0.1"

android:toAlpha="1.0"

android:duration="300" />

</set>

zoomout.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/decelerate_interpolator"
     android:zAdjustment="top">
    <scale android:fromXScale="1.0" android:toXScale=".5"
           android:fromYScale="1.0" android:toYScale=".5"
           android:pivotX="50%p" android:pivotY="50%p"
           android:duration="300" />
    <!-- 系统内置的动画持续时间
    android:duration="@android:integer/config_mediumAnimTime"
    -->
    <alpha android:fromAlpha="1.0" android:toAlpha="0"
           android:duration="300"/>
</set>

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android"

android:interpolator="@android:anim/decelerate_interpolator"

android:zAdjustment="top">

<scale android:fromXScale="1.0" android:toXScale=".5"

android:fromYScale="1.0" android:toYScale=".5"

android:pivotX="50%p" android:pivotY="50%p"

android:duration="300" />

<!-- 系统内置的动画持续时间

android:duration="@android:integer/config_mediumAnimTime"

-->

<alpha android:fromAlpha="1.0" android:toAlpha="0"

android:duration="300"/>

</set>

然后在style.xml中建立一个样式，如下：

    <style name="Animation_Activity" parent="@android:style/Animation.Translucent">
        <item name="android:activityOpenEnterAnimation">@anim/zoomin</item>
        <item name="android:activityOpenExitAnimation">@anim/zoomout</item>
        <item name="android:activityCloseEnterAnimation">@anim/zoomin</item>
        <item name="android:activityCloseExitAnimation">@anim/zoomout</item>
    </style>

<item name="android:activityOpenEnterAnimation">@anim/zoomin</item>

<item name="android:activityOpenExitAnimation">@anim/zoomout</item>

<item name="android:activityCloseEnterAnimation">@anim/zoomin</item>

<item name="android:activityCloseExitAnimation">@anim/zoomout</item>

</style>

注意一定要继承自@android:style/Animation.Translucent

然后在Activity的主题样式里引用这个样式

    <style name="AppActivityTheme" parent="@android:style/Theme.Holo.Light">
        <item name="android:windowAnimationStyle">@style/Animation_Activity</item>
    </style>

<item name="android:windowAnimationStyle">@style/Animation_Activity</item>

</style>

最后在AndroidManifest.xml把想使用这个动画的Activity设置成这个主题就好了，如下：

        <activity
            android:name=".box.AddBoxActivity"
            android:exported="false"
            android:screenOrientation="portrait"
            android:theme="@style/AppActivityTheme" />
        <activity
            android:name=".good.GoodAddActivity"
            android:exported="false"
            android:screenOrientation="portrait"
            android:theme="@style/AppActivityTheme" />

<activity

android:name=".box.AddBoxActivity"

android:exported="false"

android:screenOrientation="portrait"

android:theme="@style/AppActivityTheme" />

<activity

android:name=".good.GoodAddActivity"

android:exported="false"

android:screenOrientation="portrait"

android:theme="@style/AppActivityTheme" />
