andriod一个不错的启动菜单显示屏动画效果

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:

<?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 点启动窗口动画效果后显示的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>

4SplashScreen.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: <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> 注意下这里<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>
