弹出动画XML
在res文件夹下,建立anim文件夹。写入如下两个文件。
弹出动画
in_lefttoright.xml
- <?xml version="1.0" encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android" >
- <!-- 定义从左向右进入的动画 -->
- <translate
- android:duration="500"
- android:fromXDelta="-100%"
- android:toXDelta="0" />
- </set>
弹回动画
out_righttoleft.xml
- <?xml version="1.0" encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android" >
- <!-- 定义从右向左动画退出动画 -->
- <translate
- android:duration="500"
- android:fromXDelta="0"
- android:toXDelta="-100%" />
- </set>
动画管理
在styles.xml中,添加如下管理代码。
- <style name="AnimationFade">
- <!-- PopupWindow左右弹出的效果 -->
- <item name="android:windowEnterAnimation">@anim/in_lefttoright</item>
- <item name="android:windowExitAnimation">@anim/out_righttoleft</item>
- </style>
