看到一个老外做的不错的android启动菜单的动画效果，小结下。

1 首先在drawable目录下放一些动画要用的图片。

2 splash.xml:

3 点启动窗口动画效果后显示的main.xml

 

4 SplashScreen.java

这里是欢迎启动类的核心部分

 

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 目录下添加样式文件 styles.xml: 
       
        
        
                
       注意下这里
