Android Activity界面切换添加动画特效

在Android 2.0之后有了void android.app.Activity.overridePendingTransition(int enterAnim, int exitAnim)，其中里面两个参数，一个是前一个activity的退出另一个是后一个activity的进入。

前一个Activity    SplashScreen:

[java]  view plain copy print ?

1. @Override  
2.     protected void onCreate(Bundle savedInstanceState) {  
3.         super.onCreate(savedInstanceState);  
4.         setContentView(R.layout.main);  
5.           
6.         new Handler().postDelayed(new Runnable(){  
7.             @Override  
8.             public void run() {  
9.                 Intent intent = new Intent(SplashScreen.this, NextActivity.class);  
10.                 SplashScreen.this.startActivity(intent);  
11.                 SplashScreen.this.finish();  
12.                                 //添加页面切换效果，留意只有android2.0（SDKVersion版本号为5）以后的版本才支持  
13.                 int version = Integer.valueOf(android.os.Build.VERSION.SDK);  
14.                 if(5 <= version){  
15.                      //淡入淡出效果  
16.                      //overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);  
17.                      //由左向右滑入  
18.                              //overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);  
19.                      //Ipone式的切换效果,自定义 zoomin.xml,zoomout.xml  
20.                      overridePendingTransition(R.anim.zoomin,R.anim.zoomout);  
21.                                     //getWindow ().setWindowAnimations ( int );  
22.                                 　　//这可没有上个好但是也可以 。  
23.                                 }  
24.             }  
25.         }, 3000);  
26.     }  

res/anim/zoomin.xml:

[html]  view plain copy print ?

1. <?xml version="1.0" encoding="utf-8"?>  
2. <set xmlns:android="http://schemas.android.com/apk/res/android"  
3.     android:interpolator="@android:anim/decelerate_interpolator">  
4.     <scale android:fromXScale="2.0" android:toXScale="1.0"  
5.         android:fromYScale="2.0" android:toYScale="1.0"  
6.         android:pivotX="50%p" android:pivotY="50%p"  
7.         android:duration="@android:integer/config_mediumAnimTime"  
8.         />  
9. </set>  

res/anim/zoomout.xml:

[html]  view plain copy print ?

1. <?xml version="1.0" encoding="utf-8"?>  
2. <set xmlns:android="http://schemas.android.com/apk/res/android"  
3.     android:interpolator="@android:anim/decelerate_interpolator"  
4.     android:zAdjustment="top">  
5.     <scale android:fromXScale="1.0" android:toXScale=".5"  
6.         android:fromYScale="1.0" android:toYScale=".5"  
7.         android:pivotX="50%p" android:pivotY="50%p"  
8.         android:duration="@android:integer/config_mediumAnimTime"  
9.         />  
10.     <alpha android:fromAlpha="1.0" android:toAlpha="0"  
11.         android:duration="@android:integer/config_mediumAnimTime"  
12.         />  
13. </set>
