popwindow通过setAnimationStyle(int animationStyle)函数来设置动画效果
android:windowEnterAnimation表示进入窗口动画
android:windowExitAnimation表示窗口退出动画
在res/values/style.xml代码:
- <?xml version="1.0"encoding="utf-8"?>
- <resources>
- <style name="PopupAnimation"parent="android:Animation"mce_bogus="1">
- <item name="android:windowEnterAnimation">@anim/popup_enter</item>
- <item name="android:windowExitAnimation">@anim/popup_exit</item>
- </style>
- </resources>
在res/anim/popup_enter.xml声明所需进入动画
- <?xml version="1.0"encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android">
- <scale android:fromXScale="0.6"android:toXScale="1.0"
- android:fromYScale="0.6"android:toYScale="1.0"android:pivotX="50%"
- android:pivotY="50%"android:duration="1000"/>
- <alpha android:interpolator="@android:anim/decelerate_interpolator"
- android:fromAlpha="0.0"android:toAlpha="1.0"android:duration="1000"/>
- </set>
在res/anim/popup_exit.xml声明所需退出动画
- <?xml version="1.0"encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android">
- <scale
- android:fromXScale="1.0"
- android:toXScale="0.5"
- android:fromYScale="1.0"
- android:toYScale="0.5"
- android:pivotX="50%"
- android:pivotY="50%"
- android:duration="500"/>
- <alpha
- android:interpolator="@android:anim/accelerate_interpolator"
- android:fromAlpha="1.0"
- android:toAlpha="0.0"
- android:duration="500"/>
- </set>
设置popwindow的位置及动画
popupWindow.setAnimationStyle(R.style.PopupAnimation);
popupWindow.showAtLocation(findViewById(R.id.parent), Gravity.CENTER| Gravity.CENTER, 0, 0);
popupWindow.update();
调用popupWindow.dismiss();语句。popwindow消失,自动调用消失动画popup_exit.xml
