Activity进入与退出的动画

1.在res建立目录anim放入动画效果xml文件

   1.1   进入文件  push_left_in.xml 

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="300"
        android:fromXDelta="100%p"
        android:toXDelta="0" />

    <alpha
        android:duration="300"
        android:fromAlpha="0.0"
        android:toAlpha="1.0" />

</set>

  1.2  退出文件  push_left_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="300"
        android:fromXDelta="0"
        android:toXDelta="-100%p" />

    <alpha
        android:duration="300"
        android:fromAlpha="1.0"
        android:toAlpha="0.0" />

</set>

  1.3  activity退出的效果  zoom_enter.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:duration="@android:integer/config_mediumAnimTime"
        android:fromXScale="2.0"
        android:fromYScale="2.0"
        android:pivotX="50%p"
        android:pivotY="50%p"
        android:toXScale="1.0"
        android:toYScale="1.0" />

</set>

   1.4  zoom_exit.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:duration="@android:integer/config_mediumAnimTime"
        android:fromXScale="1.0"
        android:fromYScale="1.0"
        android:pivotX="50%p"
        android:pivotY="50%p"
        android:toXScale=".5"
        android:toYScale=".5" />

    <alpha
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromAlpha="1.0"
        android:toAlpha="0" />

</set>

2. 建立style文件

<style name="ThemeActivity">
       <item name="android:windowAnimationStyle">@style/AnimationActivity</item>
       <item name="android:windowNoTitle">true</item>
   </style>

   <style name="AnimationActivity" parent="@android:style/Animation.Activity">
       <item name="android:activityOpenEnterAnimation">@anim/push_left_in</item>
       <item name="android:activityOpenExitAnimation">@anim/push_left_out</item>
       <item name="android:activityCloseEnterAnimation">@anim/zoom_enter</item>
       <item name="android:activityCloseExitAnimation">@anim/zoom_exit</item>
   </style>

3.在Application中调用主题

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/ThemeActivity"
        >

4.  测试过程中确保手机的动画效果开启，否则达不到效果
