Activity的进入，退出动画设置

如果想要所有的Activity都使用同一个进入退出动画，则可以把Theme放到Application标签中

<application
     android:theme="@style/activity_switch" >
           

activity_swich主题的代码是：

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
</style>


<style name="activity_switch" parent="AppTheme">
    <item name="android:windowAnimationStyle">@style/activity_switch_animation</item>
</style>


   <style name="activity_switch_animation" >
       <item name="android:activityOpenEnterAnimation">@anim/activity_slide_in_right</item>
       <item name="android:activityOpenExitAnimation">@anim/activity_slide_out_left</item>
       <item name="android:activityCloseEnterAnimation">@anim/activity_slide_in_left</item>
       <item name="android:activityCloseExitAnimation">@anim/activity_slide_out_right</item>
   </style>
           

四个退出进入动画是：

@anim/activity_slide_in_right

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromXDelta="100.0%"
        android:toXDelta="0.0" />
</set>
           

@anim/activity_slide_out_left

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromXDelta="0.0%"
        android:toXDelta="-100.0%" />
</set>
           

@anim/activity_slide_in_left

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromXDelta="-100.0%"
        android:toXDelta="0.0" />
</set>
           

@anim/activity_slide_out_right

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromXDelta="0.0%"
        android:toXDelta="100.0%" />
</set>
           

这个主题可以实现所有的Activity，从左右平滑进入滑出。
