• 1.主要是以下这个属性

1. parent=“Theme.MaterialComponents.Light.NoActionBar.Bridge” 使用Light主题
2. name=“android:forceDarkAllowed” 强制关闭

• 2.完整的代码

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Theme.Base" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/color_F3F3F1</item>
        <item name="colorPrimaryVariant">@color/color_F3F3F1</item>
        <item name="colorOnPrimary">@android:color/black</item>
        <item name="android:forceDarkAllowed" tools:targetApi="q">false</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/color_FFC01F</item>
        <item name="colorSecondaryVariant">@color/color_FFC01F</item>
        <item name="colorOnSecondary">@android:color/white</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
        <item name="android:windowBackground">@color/color_F3F3F1</item>
        <item name="colorControlActivated">@color/color_FFC01F</item>
    </style>
</resources>
