Android自定义Activity酷炫的动画跳转效果

两个Activity跳转的时候，自定义翻页效果：

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);   
startActivityForResult(intent, 11);   
               
//添加界面切换效果，注意只有Android的2.0(SdkVersion版本号为5)以后的版本才支持   
int version = Integer.valueOf(android.os.Build.VERSION.SDK);      
if(version  >= 5) {      
     overridePendingTransition(R.anim.zoomin, R.anim.zoomout);  //此为自定义的动画效果，下面两个为系统的动画效果   
   //overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);     
     //overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);   
}

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
startActivityForResult(intent, 11);
      
//添加界面切换效果，注意只有Android的2.0(SdkVersion版本号为5)以后的版本才支持
int version = Integer.valueOf(android.os.Build.VERSION.SDK);   
if(version  >= 5) {   
     overridePendingTransition(R.anim.zoomin, R.anim.zoomout);  //此为自定义的动画效果，下面两个为系统的动画效果
   //overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);  
     //overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);
}

下面为两个自定义的动画效果XML文件，存放位置为：res/anim/

1，动画进入效果：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:fromYScale="2.0" android:toYScale="1.0"  
           android:pivotX="50%p" android:pivotY="50%p"  
           android:duration="@android:integer/config_mediumAnimTime" />   
</set>

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"

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

2，动画退出效果：zoomout.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" />   
    <alpha android:fromAlpha="1.0" android:toAlpha="0"
