Android Activity的切换动画

Android的Activity切换有两种方法,

第一种是用代码方式实现:

Activity A跳转到Activity B,要在startActivity(intent)后面加上overridePendingTransition(R.anim.anim_in, R.anim.anim_out);

Activity B返回Activity A,要在finish()后面加上overridePendingTransition(R.anim.anim_in, R.anim.anim_out);

anim_in是进入的Activity的动画,anim_out是退出的Activity的动画。

第二种方法是使用theme实现:(manifest中)

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

styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" mce_bogus="1" parent="@android:style/Theme.Light">
        <item name="android:windowAnimationStyle">@style/default_animation</item>
        <item name="android:windowNoTitle">true</item>
    </style>

    <!-- 默认Activity跳转动画 -->
    <style name="default_animation" mce_bogus="1" parent="@android:style/Animation.Activity">
        <item name="android:activityOpenEnterAnimation">@anim/default_anim_in</item>
        <item name="android:activityOpenExitAnimation">@anim/anim_stay</item>
        <item name="android:activityCloseEnterAnimation">@anim/anim_stay</item>
        <item name="android:activityCloseExitAnimation">@anim/default_anim_out</item>
    </style>
</resources>

然后就是在res/anim文件夹中定义对应的动画文件default_anim_in,anim_stay, default_anim_out。

4个item分别代表 

Activity A跳转到Activity B时Activity B进入动画;

Activity A跳转到Activity B时Activity A退出动画;

Activity B返回Activity A时Activity A的进入动画

Activity B返回Activity A时ActivityB的退出动画

 

anim_stay.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
            android:duration="4000"
            android:fromXDelta="0"
            android:fromYDelta="0"
            android:toXDelta="0"
            android:toYDelta="0"/>
</set>

default_anim_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
            android:duration="1600"
            android:fromXScale="0.7"
            android:fromYScale="0.7"
            android:interpolator="@android:anim/accelerate_decelerate_interpolator"
            android:pivotX="50%"
            android:pivotY="50%"
            android:toXScale="1"
            android:toYScale="1"/>

    <alpha
            android:duration="1600"
            android:fromAlpha="0"
            android:toAlpha="1.0"/>
</set>

default_anim_out.xml

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

    <scale
            android:duration="1600"
            android:fromXScale="1"
            android:fromYScale="1"
            android:interpolator="@android:anim/accelerate_decelerate_interpolator"
            android:pivotX="50%"
            android:pivotY="50%"
            android:toXScale="0.7"
            android:toYScale="0.7" />

    <alpha
            android:duration="1600"
            android:fromAlpha="1"
            android:toAlpha="0" />

</set>
