在Android 2.0之后有了void android.app.Activity.overridePendingTransition(int enterAnim, int exitAnim)，其中里面两个参数，一个是前一个activity的退出另一个是后一个activity的进入。

前一个Activity    SplashScreen:

@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);new Handler().postDelayed(new Runnable(){@Overridepublic void run() {Intent intent = new Intent(SplashScreen.this, NextActivity.class);SplashScreen.this.startActivity(intent);SplashScreen.this.finish();//添加页面切换效果，留意只有android2.0（SDKVersion版本号为5）以后的版本才支持int version = Integer.valueOf(android.os.Build.VERSION.SDK);if(5 <= version){//淡入淡出效果//overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);//由左向右滑入//overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);//Ipone式的切换效果,自定义 zoomin.xml,zoomout.xmloverridePendingTransition(R.anim.zoomin,R.anim.zoomout);//getWindow ().setWindowAnimations ( int );//这可没有上个好但是也可以 。}}}, 3000);}

res/anim/zoomin.xml:

<?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>

res/anim/zoomout.xml:

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