AOSP-如何修改全局的Activity切换动画呢？

修改路径：

${ANDROID_SOURCE}/frameworks/base/core/res/res/values/style.xml

代码

   <!-- Standard animations for a full-screen window or activity. -->
    <style name="Animation.Activity">
        <item name="activityOpenEnterAnimation">@anim/activity_open_enter</item>
        <item name="activityOpenExitAnimation">@anim/activity_open_exit</item>
        <item name="activityCloseEnterAnimation">@anim/activity_close_enter</item>
        <item name="activityCloseExitAnimation">@anim/activity_close_exit</item>
        <item name="taskOpenEnterAnimation">@anim/task_open_enter</item>
        <item name="taskOpenExitAnimation">@anim/task_open_exit</item>
        <item name="taskCloseEnterAnimation">@anim/task_close_enter</item>
        <item name="taskCloseExitAnimation">@anim/task_close_exit</item>
        <item name="taskToFrontEnterAnimation">@anim/task_open_enter</item>
        <item name="taskToFrontExitAnimation">@anim/task_open_exit</item>
        <item name="taskToBackEnterAnimation">@anim/task_close_enter</item>
        <item name="taskToBackExitAnimation">@anim/task_close_exit</item>
        <item name="wallpaperOpenEnterAnimation">@anim/wallpaper_open_enter</item>
        <item name="wallpaperOpenExitAnimation">@anim/wallpaper_open_exit</item>
        <item name="wallpaperCloseEnterAnimation">@anim/wallpaper_close_enter</item>
        <item name="wallpaperCloseExitAnimation">@anim/wallpaper_close_exit</item>
        <item name="wallpaperIntraOpenEnterAnimation">@anim/wallpaper_intra_open_enter</item>
        <item name="wallpaperIntraOpenExitAnimation">@anim/wallpaper_intra_open_exit</item>
        <item name="wallpaperIntraCloseEnterAnimation">@anim/wallpaper_intra_close_enter</item>
        <item name="wallpaperIntraCloseExitAnimation">@anim/wallpaper_intra_close_exit</item>
        <item name="fragmentOpenEnterAnimation">@animator/fragment_open_enter</item>
        <item name="fragmentOpenExitAnimation">@animator/fragment_open_exit</item>
        <item name="fragmentCloseEnterAnimation">@animator/fragment_close_enter</item>
        <item name="fragmentCloseExitAnimation">@animator/fragment_close_exit</item>
        <item name="fragmentFadeEnterAnimation">@animator/fragment_fade_enter</item>
        <item name="fragmentFadeExitAnimation">@animator/fragment_fade_exit</item>
    </style>

有同学可能已经发现了，还有fragment的切换也有了是吧。

因此，我们去修改对应的动画片配置文件，或者新写，替换上面的配置即可。

fragment的动画所在路径:

${ANDROID_SOURCE}/frameworks/base/core/res/res/animator

Activity切换的动画所在动画

${ANDROID_SOURCE}/frameworks/base/core/res/res/anim
