overridePendingTransition 页面转换动画

在startActivity后，调用overridePendingTransition方法，例如，
一)实现淡入淡出的效果如下:

 

startActivity(new Intent(SplashActivity.this, MainActivity.class));

SplashActivity.this.finish();

overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);

二)由左向右滑入的效果改变一下参数即可

overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);

三)要实现zoomin和zoomout,即类似iphone的进入和退出时的效果

在res目录下新建文件夹anim,然后在anim下新建两个xml,默认选项不用更改，分别命名为zoomin.xml和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" >

  <scale

        android:duration="@android:integer/config_mediumAnimTime"

        android:fromXScale="2.0"

        android:fromYScale="2.0"

        android:pivotX="50%p"

        android:pivotY="50%p"

        android:toXScale="1.0"

        android:toYScale="1.0" />

</set>

<?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:duration="@android:integer/config_mediumAnimTime"

        android:fromXScale="1.0"

        android:fromYScale="1.0"

        android:pivotX="50%p"

        android:pivotY="50%p"

        android:toXScale=".5"

        android:toYScale=".5" />

    <alpha

        android:duration="@android:integer/config_mediumAnimTime"

        android:fromAlpha="1.0"

        android:toAlpha="0" />

</set>
