1 首先在drawable目錄下放一些動畫要用的圖片。

2 splash.xml:
<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android 
android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:id="@+id/TheSplashLayout"
  android:layout_gravity="center"
  > 
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/SplashImageView"
android:layout_gravity="center"       
> 
</ImageView>

  3 點启動窗口動畫效果後顯示的main.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    /> 
<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
    /> 
</LinearLayout> 

  

3 SplashScreen.java
這裏是歡迎启動類的核心部分
public class SplashScreen extends Activity {
   /** 
     * The thread to process splash screen events 
     */
    private Thread mSplashThread;       /** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState);    // Splash screen view 
    setContentView(R.layout.splash); 
     
        // Start animating the image 
    final ImageView splashImageView = (ImageView) findViewById(R.id.SplashImageView); 
    splashImageView.setBackgroundResource(R.drawable.flag); 
    final AnimationDrawable frameAnimation = (AnimationDrawable)splashImageView.getBackground(); 
    splashImageView.post(new Runnable(){ public void run() { 
frameAnimation.start();        
}            
    }); 
         
     
    final SplashScreen sPlashScreen = this;   
     
    // The thread to wait for splash screen events 
    mSplashThread =  new Thread(){ 
    @Override
    public void run(){ 
    try { 
    synchronized(this){ 
    // Wait given period of time or exit on touch 
    wait(5000); 
    } 
    } 
    catch(InterruptedException ex){    
    }finish(); 
     
    // Run next activity 
    Intent intent = new Intent(); 
    intent.setClass(sPlashScreen, MainActivity.class); 
    startActivity(intent); 
    stop();     
    } 
    }; 
     
    mSplashThread.start(); 
     
}@Override
public boolean onCreateOptionsMenu(Menu menu){ 
super.onCreateOptionsMenu(menu); 
return false; 
} 
   
    /** 
     * Processes splash screen touch events 
     */
    @Override
    public boolean onTouchEvent(MotionEvent evt) 
    { 
    if(evt.getAction() == MotionEvent.ACTION_DOWN) 
    { 
    synchronized(mSplashThread){ 
    mSplashThread.notifyAll(); 
    } 
    } 
    return true; 
    } 
 

 4 为了更好看,在values 目錄下添加样式文件styles.xml: 

 <resources> 
<style name="Animations" parent="@android:Animation" /> 
<style name="Animations.SplashScreen"> 
        <item name="android:windowEnterAnimation">@anim/appear</item> 
        <item name="android:windowExitAnimation">@anim/disappear</item> 
    </style> 
<style name="Theme.Transparent" parent="android:Theme"> 
<item name="android:windowIsTranslucent">true</item> 
<item name="android:windowBackground">@android:color/transparent</item> 
<item name="android:windowContentOverlay">@null</item> 
<item name="android:windowNoTitle">true</item> 
<item name="android:windowIsFloating">true</item> 
<item name="android:backgroundDimEnabled">false</item> 
<item name="android:windowAnimationStyle">@style/Animations.SplashScreen</item>        
</style>        
</resources> 

 注意下這裏:

<style name="Animations" parent="@android:Animation" /> 
<style name="Animations.SplashScreen"> 
        <item name="android:windowEnterAnimation">@anim/appear</item> 
        <item name="android:windowExitAnimation">@anim/disappear</item> 
    </style>
