Activity动画切换overridePendingTransition

实现两个 Activity 切换时的动画使用方法overridePendingTransition，它有两个参数：进入动画和出去的动画。注意：必须在 StartActivity()或 finish() 之后立即调用。一、实现淡入浅出的效果

startActivity(new Intent(MainActivity.this,SecondActivity.class));
overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);

二、从左向右滑入的效果

startActivity(new Intent(MainActivity.this,SecondActivity.class));
overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);

三、实现zoommin 和 zoomout (自定义的动画)

startActivity(new Intent(OverridePendingTransitionActivity.this,SecondActivity.class));overridePendingTransition(R.anim.zoomin, R.anim.zoomout);

在anim中定义动画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" ><scaleandroid:duration="@android:integer/config_mediumAnimTime"android:fromXScale="0.1"android:fromYScale="0.1"android:pivotX="50%p"android:pivotY="50%p"android:toXScale="1.0"android:toYScale="1.0" /><alphaandroid:duration="@android:integer/config_mediumAnimTime"android:fromAlpha="0"android:toAlpha="1.0" /></set>

在anim中定义动画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:zAdjustment="top" ><scaleandroid:duration="@android:integer/config_mediumAnimTime"android:fromXScale="1.0"android:fromYScale="1.0"android:pivotX="50%p"android:pivotY="50%p"android:toXScale="0.1"android:toYScale="0.1" /><alphaandroid:duration="@android:integer/config_mediumAnimTime"android:fromAlpha="1.0"android:toAlpha="0" /></set>
