android - 我无法在android studio中更改操作栏的颜色，它卡在黑色中

Question

我是android studio的新手，我正在学习更改android studio中动作栏的颜色，当手机的暗模式（暗主题）没有打开时，我可以更改颜色，但是当我转身时在暗模式下，操作栏的颜色变为黑色。我没有对 main_activity.xml 文件进行任何更改，因此我没有在此处编写代码，但我正在共享 theme.xml 的代码，因为它是我对它进行了一些更改的唯一文件。

夜晚/themes.xml

'''<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Theme.ActionBar" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/green</item>
        <item name="colorPrimaryVariant">@color/purple_700</item>
        <item name="colorOnPrimary">@color/black</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_200</item>
        <item name="colorOnSecondary">@color/black</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
