安卓5.0 Transitions动画切换时状态栏不参与动画

1、在values-21文件夹下主题中设置Transitions动画

    <style name="AppTheme" parent="@android:style/Theme.Light.NoTitleBar">
        <item name="android:windowBackground">@drawable/aaa_cycle</item>
        <!--<item name="android:windowIsTranslucent">true</item>-->
        <item name="android:windowNoTitle">true</item>
        <!--<item name="android:statusBarColor">@android:color/transparent</item>-->
        <!--<item name="android:windowTranslucentStatus">false</item>-->
        <!--允许使用transitions-->
        <item name="android:windowActivityTransitions">true</item>      <!--这一句必须添加，否则Activity动画无效-->
        <item name="android:windowContentTransitions">true</item>
        <item name="android:windowAllowEnterTransitionOverlap">true</item>
        <item name="android:windowAllowReturnTransitionOverlap">true</item>
        <!-- 指定进入和退出transitions -->
        <item name="android:windowEnterTransition">@transition/transitionset_in</item>
        <item name="android:windowExitTransition">@transition/transitionset_out</item>
        <item name="android:windowSharedElementsUseOverlay">false</item>
    </style>

2、在res文件夹下新建transition文件夹，并添加动画文件

<?xml version="1.0" encoding="utf-8"?>
<transitionSet xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:transitionOrdering="together">
    <!--<fade android:fadingMode="fade_in">-->
        <!--<targets>-->
            <!--<target android:excludeId="@android:id/statusBarBackground" />-->
            <!--<!–<target android:excludeId="@android:id/navigationBarBackground" />–>-->
        <!--</targets>-->
    <!--</fade>-->

    <slide
        android:slideEdge="end">
        <targets>
            <target android:excludeId="@android:id/statusBarBackground" />    <!-- 状态栏不参与动画过程 -->
            <!--<target android:excludeId="@android:id/navigationBarBackground" />-->
        </targets>
    </slide>
    <!--android:interpolator="@android:interpolator/decelerate_quad"-->
</transitionSet>

3、在代码中设置动画

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            startActivity(intent, ActivityOptions.makeSceneTransitionAnimation(this).toBundle());
        } else {
            startActivity(intent);
        }
