theme-windowAnimationStyle 动画四个方法的意义

首先看代码

<style name="Animation.Activity"> 
       <!--A打开B,B的出现动画-->
        <item name="activityOpenEnterAnimation">@anim/activity_open_enter</item>

        <!--A打开B,A的消失动画-->
        <item name="activityOpenExitAnimation">@anim/activity_open_exit</item>
         <!--A关闭B,B的出现动画-->
        <item name="activityCloseEnterAnimation">@anim/activity_close_enter</item>

         <!--A关闭B,A的消失动画-->

         <item name="activityCloseExitAnimation">@anim/activity_close_exit</item> 
</style>

现在我们有两个activity:

VzGalleryActivity(启动者)

AlbumActivity(被启动者)

 

他们的style分别如下

<style name="PhotoGridLayout">
    <item name="android:drawSelectorOnTop">true</item>
    <item name="android:listSelector">@drawable/photogrid_list_selector</item>
</style>

<style name="AppTheme.Album" parent="@style/AppTheme">
    <item name="android:windowAnimationStyle">@style/AnimBottom.Album</item>
</style>

<style name="AppTheme.VzGallery" parent="@style/AppTheme.Main">
    <item name="android:windowAnimationStyle">@style/AnimBottom.VzGallery</item>
</style>

<style name="AnimBottom.VzGallery" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_bottom_out</item>
    <item name="android:activityOpenExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseEnterAnimation">@anim/push_bottom_out</item>
</style>
<style name="AnimBottom.Album" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_bottom_enter</item>
    <item name="android:activityOpenExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseExitAnimation">@anim/push_bottom_enter</item>
    <item name="android:activityCloseEnterAnimation">@anim/push_bottom_out</item>
</style>

两个启动动画分别为

out.xml

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

    <translate
        android:duration="1000"
        android:fromYDelta="0"
        android:toYDelta="100%p"
    />
    <alpha
        android:duration="1000"
        android:fromAlpha="1.0"
        android:toAlpha="0.0" />
</set>

enter.xml

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

    <translate
        android:duration="1000"
        android:fromYDelta="100%p"
        android:toYDelta="0"
    />
    <alpha
        android:duration="1000"
        android:fromAlpha="0"
        android:toAlpha="1.0" />
</set>

1)我们更改动画如下

<style name="PhotoGridLayout">
    <item name="android:drawSelectorOnTop">true</item>
    <item name="android:listSelector">@drawable/photogrid_list_selector</item>
</style>
<!-- Vanzo:zhangshuli on: Fri, 27 Mar 2015 16:34:18 +0000
-->
<style name="AppTheme.Album" parent="@style/AppTheme">
    <item name="android:windowAnimationStyle">@style/AnimBottom.Album</item>
</style>

<style name="AppTheme.VzGallery" parent="@style/AppTheme.Main">
    <item name="android:windowAnimationStyle">@style/AnimBottom.VzGallery</item>
</style>

<style name="AnimBottom.VzGallery" parent="@android:style/Animation.Activity"> </style>
<style name="AnimBottom.Album" parent="@android:style/Animation.Activity">
    <item       name="android:activityOpenEnterAnimation">@anim/push_bottom_enter</item>

</style>

当,vz启动al的时候,al 有动画效果,

其他情况下,vz,al均没有效果

2)更改如下

<style name="AppTheme.Album" parent="@style/AppTheme">
    <item name="android:windowAnimationStyle">@style/AnimBottom.Album</item>
</style>

<style name="AppTheme.VzGallery" parent="@style/AppTheme.Main">
</style>

<style name="AnimBottom.VzGallery" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_bottom_out</item>
    <item name="android:activityOpenExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseEnterAnimation">@anim/push_bottom_out</item>
</style>
<style name="AnimBottom.Album" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_bottom_enter</item>
    <item name="android:activityOpenExitAnimation">@anim/push_bottom_out</item>
</style>

vz启动al时候,al跟vz都有动画效果,vz消失动画效果,al出现动画效果

其他情况下没有动画效果(包括al启动其他activity)

3)更改如下

<style name="AppTheme.Album" parent="@style/AppTheme">
    <item name="android:windowAnimationStyle">@style/AnimBottom.Album</item>
</style>

<style name="AppTheme.VzGallery" parent="@style/AppTheme.Main">
</style>

<style name="AnimBottom.VzGallery" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_bottom_out</item>
    <item name="android:activityOpenExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseEnterAnimation">@anim/push_bottom_out</item>
</style>
<style name="AnimBottom.Album" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_bottom_enter</item>
    <item name="android:activityOpenExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseEnterAnimation">@anim/push_bottom_out</item>
</style>

当打开al的时候,al,vz都有动画

但是,关闭al的时候,他们都没有动画

接着,我们通过al,打开另一个activity,al,跟另一个activity没有动画,

最后,我们关闭al打开的activity的时候,al有动画,其他相关activity没有动画

4)更改如下

<style name="AppTheme.Album" parent="@style/AppTheme">
    <item name="android:windowAnimationStyle">@style/AnimBottom.Album</item>
</style>

<style name="AppTheme.VzGallery" parent="@style/AppTheme.Main">
</style>

<style name="AnimBottom.VzGallery" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_bottom_out</item>
    <item name="android:activityOpenExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseEnterAnimation">@anim/push_bottom_out</item>
</style>
<style name="AnimBottom.Album" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_bottom_enter</item>
    <item name="android:activityOpenExitAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseEnterAnimation">@anim/push_bottom_out</item>
    <item name="android:activityCloseExitAnimation">@anim/push_bottom_enter</item>
</style>

打开al的时候,al,vz都有动画

关闭al的时候,都没有动画

al打开另外一个activity的时候,都没有动画

当另一个activity结束的时候,al跟另一个activity都有动画

我们可以得出如下结论

(1)这四个属性,针对的都是自己

(2)open属性,是自己被打开的时候的相关动画,也就是自己出现的时候(被打开),其实就是自己跟父activity的动画情况

         close属性,是自己消失的时候的动画属性(打开别人),其实就是自己跟子activity的动画情况

(3)enter属性,是出现在屏幕中,自己或者跟自己相关的其他activity

         exit属性,是退出屏幕,自己或者跟自己相关的activity
