如何在Android11中禁用夜间模式？

我尝试删除 night theme.xml，并尝试在 night 主题中进行颜色更改。我也试过

AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);

但这些都没有奏效。

这是我的theme.xml：

<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Theme.app" parent="Theme.AppCompat.DayNight.NoActionBar">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/light_blue</item>
        <item name="colorPrimaryVariant">@color/light_blue</item>
        <item name="colorOnPrimary">@color/white</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_700</item>
        <item name="colorOnSecondary">@color/black</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
    </style>

</resources>

我该怎么做？
