为什么我的搜索栏亮度设置锁定更改，我该如何解决

Question

我使用了一些代码来改变项目页面中自定义搜索栏的亮度。但是每当我使用此代码时，我都无法通过通知栏更改 phone 的亮度。它被锁定了。我怎样才能同时访问它们？

              val backLightValue = (it.view.progress / 100f)
              settingLawTextData.seekBarProgress = backLightValue
              val layoutParams = activity?.window?.attributes
              layoutParams?.screenBrightness = backLightValue
              activity?.window?.attributes = layoutParams

我还使用此代码将亮度级别恢复为原始级别，但是通知面板中的亮度控制搜索栏仍然被锁定

override fun onClick(v: View?) {
    when (v?.id) {
        R.id.imgCancel -> {
            val brightness = android.provider.Settings.System.getInt(activity?.contentResolver, android.provider.Settings.System.SCREEN_BRIGHTNESS)
            val layoutParams: WindowManager.LayoutParams = requireActivity().window.attributes
            layoutParams.screenBrightness = brightness / 100.0f
            activity?.window?.attributes = layoutParams

            findNavController().navigateUp()
        }
    }
}

每当你想让系统再次获得电源时使用这个来设置亮度：

        val layoutParams = requireActivity().window?.attributes
        layoutParams?.screenBrightness = WindowManager.LayoutParams.BRIGHTNESS_OVERRIDE_NONE
        requireActivity().window?.attributes = layoutParams
