几种动画

1、slide_left_in

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

    <translate
        android:duration="800"
        android:fromXDelta="-100%p"
        android:toXDelta="0" />

    <alpha
        android:duration="800"
        android:fromAlpha="1.0"
        android:toAlpha="1.0" />

</set>

2、slide_left_out

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

    <translate
        android:duration="800"
        android:fromXDelta="0"
        android:toXDelta="-100%p" />

    <alpha
        android:duration="800"
        android:fromAlpha="1.0"
        android:toAlpha="1.0" />

</set>

3、slide_right_in

        android:duration="800"
        android:fromAlpha="1.0"
        android:toAlpha="1.0" />

</set>

4、slide_right_out

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

    <translate
