动画效果代码： values-styles.xml

<style name="PopWindowFadeInOut"> <item name="android:windowEnterAnimation">@anim/anim_fade_in</item> <item name="android:windowExitAnimation">@anim/anim_fade_out</item> </style>

res-anim目录下动画 anim_fade_in.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" android:duration="300" android:fillAfter="true" > <alpha android:fromAlpha="0" android:toAlpha="1" /></set>

anim_fade_out.xml

使用代码：

popWindowForHomeCategory = new PopWindowForHomeCategory(getActivity());popWindowForHomeCategory.setOnDismissListener(xxx);popWindowForHomeCategory.setOnItemClickListener(xxx);popWindowForHomeCategory.showAsDropDown(view);
