Android Activity界面切换添加动画特效

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:

 @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         new Handler().postDelayed(new Runnable(){
             @Override
             public 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.xml
                      overridePendingTransition(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">

         android:pivotX="50%p" android:pivotY="50%p"
         android:duration="@android:integer/config_mediumAnimTime"
         />
 </set>

res/anim/zoomout.xml:

         android:duration="@android:integer/config_mediumAnimTime"
         />
     <alpha android:fromAlpha="1.0" android:toAlpha="0"
         android:duration="@android:integer/config_mediumAnimTime"
         />
 </set>
