WindowAnimationStyle

主题中定义窗口window或Activity的进入退出动画集合，用于theme的Style，例如/res/styles.xml下

    <!-- Base application theme. -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="android:textAllCaps">false</item>
        <item name="android:windowActionBar">false</item>
        <item name="windowActionBar">false</item>
        <item name="android:windowAnimationStyle">@style/AnimationActivity</item>
        <item name="windowNoTitle">true</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
    </style>

而自定义AnimationActivity如下

    <style name="AnimationActivity" parent="@android:style/Animation.Activity">
        <item name="android:activityOpenEnterAnimation">@anim/slide_in_left</item>
        <item name="android:activityOpenExitAnimation">@anim/slide_out_left</item>
        <item name="android:activityCloseEnterAnimation">@anim/slide_in_right</item>
        <item name="android:activityCloseExitAnimation">@anim/slide_out_right</item>
    </style>

其中@android:style/Animation.Activity为系统的style定义，如下

<!-- Window animation class attributes. -->
<declare-styleable name="WindowAnimation">
    <!-- The animation used when a window is being added. -->
    <attr name="windowEnterAnimation" format="reference" />
    <!-- The animation used when a window is being removed. -->

    <!-- The animation used when a window is going from INVISIBLE to VISIBLE. -->
    <attr name="windowShowAnimation" format="reference" />
    <!-- The animation used when a window is going from VISIBLE to INVISIBLE. -->
    <attr name="windowHideAnimation" format="reference" />

    <!--  When opening a new activity, this is the animation that is

    <attr name="wallpaperOpenEnterAnimation" format="reference" />
    <!--  When opening a new activity that shows the wallpaper, while

    <!--  When opening a new activity from a RemoteViews, this is the

    <attr name="activityOpenRemoteViewsEnterAnimation" format="reference" />

</declare-styleable>

可以还有定义系统的FragmentAnimation

    <!-- Fragment animation class attributes. -->
    <declare-styleable name="FragmentAnimation">
        <attr name="fragmentOpenEnterAnimation" format="reference" />
        <attr name="fragmentOpenExitAnimation" format="reference" />
        <attr name="fragmentCloseEnterAnimation" format="reference" />
        <attr name="fragmentCloseExitAnimation" format="reference" />
        <attr name="fragmentFadeEnterAnimation" format="reference" />
        <attr name="fragmentFadeExitAnimation" format="reference" />
    </declare-styleable>
