二、代码
1.resanim下的xml
(1)alpha.xml.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator">
    <alpha 
        android:fromAlpha="1.0"
        android:toAlpha="0.0"
        android:startOffset="500"
        android:duration="1000"/>
</set>

(2)rotate.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator">
    <rotate 
        android:fromDegrees="0"
        android:toDegrees="720"
        android:pivotX="50%"
        android:pivotY="100%"
        android:duration="3000"/>
</set>

(3)scale.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator">
    <scale 
        android:fromXScale="1.0"
        android:toXScale="0.0"
        android:fromYScale="1.0"
        android:toYScale="0.0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:duration="2000"/>
    
</set>

(4)tranlate.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator">
    <translate 
        android:fromXDelta="50%"
        android:toXDelta="100%"
        android:fromYDelta="0%"
        android:toYDelta="100%"
        android:duration="2000"/>
</set>
