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>
<mce:style name="PopupAnimation" parent="android:Animation"><!--
<item name="android:windowEnterAnimation">@anim/popup_enter</item>
<item name="android:windowExitAnimation">@anim/popup_exit</item>
--></mce:style><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
activity切换动画
public void onClick(View v) {
Intent intent = new Intent(ActivityAnim.this,ActivityTwo.class);
startActivity(intent);
overridePendingTransition(R.anim.act_enter,R.anim.act_exit);
}
overridePendingTransition(int ,int)函数,第一个参数为activity显示动画,第二个参数为退出动画,两个动画的xml文件存放在anim文件夹下
