Accompanist systemUiController的darkIcons在Android11亮色主题下不生效问题

使用Accompanist systemUiController库时，亮色主题下设置darkIcons=false仅在Android 10及更低版本设备生效，Android 11设备上不生效。当前需求为深色状态栏下，状态栏前景/图标显示为白色。
暗色主题下darkIcons参数无论设置为true还是false，均能正常生效。

曾尝试脱离生命周期监听逻辑直接设置状态栏颜色，问题仍复现。

状态栏基础配置代码 #

val systemUiController = rememberSystemUiController()
systemUiController.setStatusBarColor(color=statusBarColor,darkIcons=false) 

主题配置代码（Theme.kt） #

private val LightBase = ASBTheme(
    material = lightColors(
        background = FigmaPrimaryWhite,
        onBackground = FigmaTextBlack,
        surface = FigmaPrimaryWhite,
        onSurface = FigmaTextBlack,
        primary = FigmaSecondaryAvastBlue,
        error = FigmaStatusPink,
    ),
    textColorLabel = FigmaSecondaryAvastPurple,
    colorAccent = FigmaPrimaryGreen,
    ... // 其余自定义颜色配置
)

private val DarkBase = ASBTheme(
    material = darkColors(
        background = FigmaPrimaryBlackBg,
        onBackground = FigmaTextWhite,
        surface = FigmaSecondaryAvastBlueDark,
        onSurface = FigmaTextWhite,
        primary = FigmaSecondaryBlackDark,
        error = FigmaStatusPink
    ),
        textColorLabel = FigmaSecondaryAvastPurpleBright,
        colorAccent = FigmaStatusGreen,
        ... // 其余自定义颜色配置
)

private val LocalAsbTheme = staticCompositionLocalOf { LightBase }
var navBarColor: Color? = null
var statusBarColor: Color? = null

@Composable
fun ASBTheme(
    darkTheme: Boolean = isSystemInDarkTheme(),
    content: @Composable () -> Unit
) {
    val colors = if (darkTheme) {
        DarkBase
    } else {
        LightBase
    }
    if (darkTheme) {
        navBarColor = DarkBase.background
        statusBarColor = DarkBase.primary
    } else {
        navBarColor = LightBase.background
        statusBarColor = LightBase.primary
    }

    SetBarsTheme(statusBarColor!!, navBarColor!!)

    CompositionLocalProvider(
        LocalAsbTheme provides colors,
    ) {
        MaterialTheme(
            colors = colors.material,
            content = content,
        )
    }
}

val MaterialTheme.asbTheme: ASBTheme
    @Composable
    @ReadOnlyComposable
    get() = LocalAsbTheme.current

状态栏样式设置方法 #

@Composable
fun SetBarsTheme(
    statusBarColor: Color,
    navigationBarColor: Color,
    darkIcons:Boolean=false,
) {
    val lifecycleOwner = LocalLifecycleOwner.current
    val systemUiController = rememberSystemUiController()

    DisposableEffect(lifecycleOwner) {
        val observer = LifecycleEventObserver { _, event ->
            if (event == Lifecycle.Event.ON_RESUME) {
               systemUiController.setStatusBarColor(color=statusBarColor,darkIcons)
                systemUiController.setNavigationBarColor(color=navigationBarColor)
            }
        }
        lifecycleOwner.lifecycle.addObserver(observer)
        onDispose {
            lifecycleOwner.lifecycle.removeObserver(observer)
        }
    }
}

这个问题是Android 11调整了状态栏外观控制优先级，和旧版本Accompanist的适配逻辑冲突导致，可按如下步骤修复：

1. 升级Accompanist依赖到0.24.0及以上版本，该版本已修复Android 11下darkIcons配置不生效的问题，注意版本需与项目使用的Compose版本匹配。
2. 修正SetBarsTheme方法的参数传递逻辑，当前调用时未主动传入darkIcons参数，默认值固定为false，需根据主题和状态栏颜色动态传入对应值：
   修改ASBTheme中调用SetBarsTheme的代码：

SetBarsTheme(
    statusBarColor = statusBarColor!!, 
    navigationBarColor = navBarColor!!,
    // 亮色主题下状态栏为深色，图标设为白色（darkIcons=false）；暗色主题同理
    darkIcons = !darkTheme && statusBarColor.luminance() > 0.5
    // 如亮色主题状态栏为浅色，可直接设置为darkIcons = !darkTheme
)

3. 如升级依赖后仍有问题，可添加原生API作为兜底适配：
   在SetBarsTheme中调用setStatusBarColor后添加如下代码：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
    val window = LocalContext.current as Activity
    window.insetsController?.setSystemBarsAppearance(
        if (darkIcons) WindowInsetsController.APPEARANCE_LIGHT_STATUS_BARS else 0,
        WindowInsetsController.APPEARANCE_LIGHT_STATUS_BARS
    )
}
