废话不多说，先看效果图：

android之动画popowindows详解手机开发

这是主Activity代码：

[java] 
view plain
copy

  1. public class RollActivity extends Activity {  
  2.     private View view;  
  3.     private Button btn;  
  4.     private PopupWindow mPopupWindow;

  11. //      LinearLayout layout=(LinearLayout) view.findViewById(R.id.layout_main);

  43.         //使用系统动画  
  44.         mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);  
  45.         mPopupWindow.update();

  48.

  89.                 mFgBitmap.getWidth(), mFgBitmap.getHeight(), mFgMatrix, true);  
  90.     }  
  91. }  

PopupWindow的布局popwindow.xml 
注意3个LinearLayout里必须设置clickable和background，这样当点击上去的时候才会有点击效果。 
android:clickable=”true” 
android:background=”@drawable/state_btn_pressed” 

[html]

  74.                 >  
  75.             </TextView>  
  76.         </LinearLayout>  
  77. </LinearLayout>  

state_btn_pressed.xml，点击的效果： 

[html] 
view plain
copy

  1. <?xml version=“1.0” encoding=“utf-8”?>  
  2. <selector xmlns:android=“http://schemas.android.com/apk/res/android”>  
  3.     <item android:state_pressed=“true”  
  4.         android:drawable=“@drawable/bg_btn_pressed”  
  5.         android:padding=“0dp”/>  
  6. </selector>  

Android 模仿迅雷的 PopupWindow 出现/消失动画 
出现：

[html] 
view plain
copy

  1. <?xml version=“1.0” encoding=“utf-8”?>  
  2. <set xmlns:android=“http://schemas.android.com/apk/res/android”>  
  3.     <scale android:fromXScale=“0.6” android:toXScale=“1.1”  
  4.         android:fromYScale=“0.6” android:toYScale=“1.1” android:pivotX=“50%”  
  5.         android:pivotY=“50%” android:duration=“200” />  
  6.     <scale android:fromXScale=“1.0” android:toXScale=“0.91”  
  7.         android:fromYScale=“1.0” android:toYScale=“0.91” android:pivotX=“50%”  
  8.         android:pivotY=“50%” android:duration=“400” android:delay=“200” />  
  9.     <alpha android:interpolator=“@android:anim/linear_interpolator”  
  10.         android:fromAlpha=“0.0” android:toAlpha=“1.0” android:duration=“400” />  
  11. </set>  

消失： 

[html] 
view plain
copy

  1. <?xml version=“1.0” encoding=“utf-8”?>  
  2. <set xmlns:android=“http://schemas.android.com/apk/res/android”>  
  3.     <scale android:fromXScale=“1.0” android:toXScale=“1.25”  
  4.         android:fromYScale=“1.0” android:toYScale=“1.25” android:pivotX=“50%”  
  5.         android:pivotY=“50%” android:duration=“200” />  
  6.     <scale android:fromXScale=“1.0” android:toXScale=“0.48”  
  7.         android:fromYScale=“1.0” android:toYScale=“0.48” android:pivotX=“50%”  
  8.         android:pivotY=“50%” android:duration=“400” android:delay=“200” />  
  9.     <alpha android:interpolator=“@android:anim/linear_interpolator”  
  10.         android:fromAlpha=“1.0” android:toAlpha=“0.0” android:duration=“400” />  
  11. </set>  

最后用下面的 XML 封装：

[html] 
view plain
copy

  1. <?xml version=“1.0” encoding=“utf-8”?>  
  2. <resources>  
  3.     <style name=“PopupAnimation” parent=“android:Animation”  
  4.         mce_bogus=“1”>  
  5.         <item name=“android:windowEnterAnimation”>@anim/anim_dialog_show</item>  
  6.         <item name=“android:windowExitAnimation”>@anim/anim_dialog_hide</item>  
  7.     </style>  
  8. </resources>
