Android--activity切换时的动画

Posted 2020-06-16

1、首先先创建四个动画文件

  ①：left_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="600"
        android:fromXDelta="-100.0%p"
        android:toXDelta="0.0" />
</set>

 

  ②：left_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="600"
        android:fromXDelta="0.0"
        android:toXDelta="-100.0%p" />
</set>

 

  ③：right_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="600"
        android:fromXDelta="100.0%p"
        android:toXDelta="0.0" />
</set>

 

  ④：right_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="600"
        android:fromXDelta="0.0"
        android:toXDelta="100.0%p" />
</set>

2、在styles.xml里写一个风格

<style name="MyTheme" parent="AppTheme">
        <item name="android:windowAnimationStyle">@style/ActivityAnimation</item>
    </style>

    <style name="ActivityAnimation">
        <item name="android:activityOpenEnterAnimation">@anim/slide_right_in</item>
        <item name="android:activityOpenExitAnimation">@anim/slide_left_out</item>
        <item name="android:activityCloseEnterAnimation">@anim/slide_left_in</item>
        <item name="android:activityCloseExitAnimation">@anim/slide_right_out</item>
    </style>

3、然后将AndroidManifest.xml文件里面的<application>标签的主题换成我们写的就可以了
