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：

[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<resources>
<stylename="PopupAnimation"parent="android:Animation"mce_bogus="1">
<itemname="android:windowEnterAnimation">@anim/popup_enter</item>
<itemname="android:windowExitAnimation">@anim/popup_exit</item>
</style>
</resources>

在res/anim/popup_enter.xml声明所需进入动画

[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<setxmlns:android="http://schemas.android.com/apk/res/android">
<scaleandroid:fromXScale="0.6"android:toXScale="1.0"
android:fromYScale="0.6"android:toYScale="1.0"android:pivotX="50%"
android:pivotY="50%"android:duration="1000"/>
<alphaandroid: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

[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<setxmlns: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
