忘了从哪学的了，感谢原作者写的很清楚

代码

配置文件

agg_test.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              android:orientation="vertical"              android:layout_width="fill_parent"              android:layout_height="fill_parent">    <ViewFlipper android:id="@+id/ViewFlipper01"                 android:layout_width="fill_parent"                 android:layout_height="fill_parent">    </ViewFlipper></LinearLayout>

res\anim文件夹下放置配置文件push_left_in.xml、push_left_out.xml、push_right_in.xml、push_right_out.xml

写法：push_left_in.xml文件

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"><translate android:fromXDelta="100%p" android:toXDelta="0"android:duration="500" /><alpha android:fromAlpha="0.1" android:toAlpha="1.0"android:duration="500" /></set>

push_left_out.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"><translate android:fromXDelta="0" android:toXDelta="-100%p"android:duration="500" /><alpha android:fromAlpha="1.0" android:toAlpha="0.1"android:duration="500" /></set>

push_right_in.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"><translate android:fromXDelta="0" android:toXDelta="100%p"android:duration="500" /><alpha android:fromAlpha="1.0" android:toAlpha="0.1"android:duration="500" /></set>

push_right_out.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"><translate android:fromXDelta="0" android:toXDelta="100%p"android:duration="500" /><alpha android:fromAlpha="1.0" android:toAlpha="0.1"android:duration="500" /></set>
