以编程方式关闭设备上的暗模式。（或其他解决方案）Android studio Kotlin

Question

所以我需要一点帮助。

我的问题是，当我的应用程序中有一个更改为暗模式的功能时，当我在设备处于亮模式时更改它时，它会很好地更改，但是当我更改它时设备处于处于深色模式，它不会改变某些东西（背景和文字）。

我找到了一个解决方案，当我在设备选项中禁用黑暗模式时，它工作正常。我只想在应用程序中更改应用程序主题时更改应用程序主题，而不是在更改设备主题时更改应用程序主题，因为它会毁了它。这个问题没有发生在 Pixel 4 模拟器上，只发生在我的 POCO F2 Pro MIUI 12.5.5 phone 上。

将其保存在您的两个主题文件中-

<item name="android:forceDarkAllowed" tools:targetApi="q">false</item>

这样设备设置就不会覆盖应用程序设置
