在Android 2.0之后有了overridePendingTransition（） ，其中里面两个参数，一个是前一个activity的退出两一个activity的进入，

@Override
      public void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState); 

              setContentView(R.layout.SplashScreen);

              new Handler().postDelayed(new Runnable() {
                      @Override
                      public void run() {
                              Intent mainIntent = new Intent(SplashScreen.this,     AndroidNews.class);
                              SplashScreen.this.startActivity(mainIntent);
                              SplashScreen.this.finish();

                              overridePendingTransition(R.anim.mainfadein,
                                      R.anim.splashfadeout);
                      }
              }, 3000);
      }

上面的代码只是闪屏的一部分。
getWindow (). setWindowAnimations ( int );   
getWindow (). setWindowAnimations ( int );

这可没有上个好但是也可以 。

实现淡入淡出的效果
overridePendingTransition(Android.R.anim.fade_in,android.R.anim.fade_out);   
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);   
overridePendingTransition(Android.R.anim.slide_in_left,android.R.anim.slide_out_right);



实现zoomin和zoomout,即类似iphone的进入和退出时的效果
overridePendingTransition(R.anim.zoomin, R.anim.zoomout);   
overridePendingTransition(R.anim.zoomin, R.anim.zoomout);



新建zoomin.xml文件

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

新建zoomout.xml文件
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:Android="http://schemas.android.com/apk/res/android"
        Android:interpolator="@android:anim/decelerate_interpolator"
        Android:zAdjustment="top">
    <scale Android:fromXScale="1.0" android:toXScale=".5"
           Android:fromYScale="1.0" android:toYScale=".5"
           Android:pivotX="50%p" android:pivotY="50%p"
           Android:duration="@android:integer/config_mediumAnimTime" />
    <alpha Android:fromAlpha="1.0" android:toAlpha="0"
            Android:duration="@android:integer/config_mediumAnimTime"/>
</set>
