Android Activity介面切換動畫

 

在android2.0中已經可以很簡單的實現Activity 之間的動畫轉場效果。在startActivity 後調用 overridePendingTransition(int enterAnim,int exitAnim),就可以實現Activity之間的動畫，

其中enterAnim 是下一個Activity的enter動畫效果，exitAnim 是當前Actitvity退出的動畫效果

@Override     

1. public void onCreate(Bundle savedInstanceState) {     
2.         super.onCreate(savedInstanceState);      
3.         setContentView(R.layout.SplashScreen);     
4.         new Handler().postDelayed(new Runnable() {     
5.                 @Override     
6.                 public void run() {     
7.                         Intent mainIntent = new Intent(SplashScreen.this, AndroidNews.class);     
8.                         SplashScreen.this.startActivity(mainIntent);     
9.                         SplashScreen.this.finish();     
10.                         overridePendingTransition(R.anim.mainfadein,     
11.                                 R.anim.splashfadeout);     
12.                 }     
13.         }, 3000);     
14. }  

 

getWindow (). setWindowAnimations ( int );      

1. 這可沒有上個好但是也可以 。  

 

實現淡入淡出的效果

overridePendingTransition(Android.R.anim.fade_in,android.R.anim.fade_out);      

 

由左向右滑入的效果

overridePendingTransition(Android.R.anim.slide_in_left,android.R.anim.slide_out_right);    

 

實現zoomin和zoomout,即類似iphone的進入和退出時的效果

overridePendingTransition(R.anim.zoomin, R.anim.zoomout);       

建立zoomin.xml檔案

<?xml version="1.0" encoding="utf-8"?>    

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

 

建立zoomout.xml檔案

<?xml version="1.0" encoding="utf-8"?>    

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