style.xml如下：
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="AppTheme" parent="android:Theme.Light" />
<style name="popupWindowAnimation" mce_bogus="1" parent="android:Animation">
<item name="android:windowEnterAnimation">@anim/enter</item>
<item name="android:windowExitAnimation">@anim/exit</item>
</style>
</resources>
enter.xml动画如下:
<?xml version="1.0" encoding="utf-8"?>
<!-- android:fromYDelta:动画开始的点离当前View X坐标上的差值 -->
<!-- 利用100%p表示该动画在当前View的最下方 -->
<set
xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="1500"
android:fromYDelta="100%p"
android:interpolator="@android:anim/decelerate_interpolator"
android:toYDelta="0" />
</set>
exit.xml动画如下:
<?xml version="1.0" encoding="utf-8"?>
<!-- Alpha=1.0表示不透明,Alpha=0.0表示透明 -->
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/decelerate_interpolator" >
<alpha
android:duration="1000"
android:fromAlpha="1.0"
android:toAlpha="0.0"
/>
</set>

PopupWindow的动画
很多时候我们把PopupWindow用作自定义的菜单，需要一个从底部向上弹出的效果，这就需要为PopupWindow添加动画。
设置动画的方法：
1.public void setAnimationStyle(int animationStyle)
2.在res/value/styles.xml添加一个sytle
3.在工程res下新建anim文件夹，在anim文件夹先新建两个xml文件 ：enter.xml， exit.xml
