Jetpack compose 中的状态栏中未显示莫代尔底片稀松布颜色

Question

将视图系统中的应用程序迁移到 Jetpack compose。

底部稀松布颜色显示在当前应用程序的状态栏上。
如何在 Jetpack compose 中重现相同的内容？

编写代码

val modalBottomSheetState = rememberModalBottomSheetState(
    initialValue = ModalBottomSheetValue.Hidden,
)
val coroutineScope = rememberCoroutineScope()

ModalBottomSheetLayout(
    sheetState = modalBottomSheetState,
    sheetContent = {
        // Not relevant
    },
) {
    Scaffold(
        scaffoldState = scaffoldState,
        topBar = {
            // Not relevant
        },
        floatingActionButton = {
            FloatingActionButton(
                onClick = {
                    coroutineScope.launch {
                        if (!modalBottomSheetState.isAnimationRunning) {
                            if (modalBottomSheetState.isVisible) {
                                modalBottomSheetState.hide()
                            } else {
                                modalBottomSheetState.show()
                            }
                        }
                    }
                },
            ) {
                Icon(
                    imageVector = Icons.Rounded.Add,
                    contentDescription = "Add",
                )
            }
        },
        modifier = Modifier
            .fillMaxSize(),
    ) { innerPadding ->
        // Not relevant - Nav graph code
    }
}

尝试使用伴奏库中的系统UI控制器来控制statusBar Color和navigationBar color

implementation "com.google.accompanist:accompanist-systemuicontroller:0.18.0"

// Remember a SystemUiController
val systemUiController = rememberSystemUiController()
val useDarkIcons = MaterialTheme.colors.isLight

SideEffect {
    // Update all of the system bar colors to be transparent, and use
    // dark icons if we're in light theme
    systemUiController.setSystemBarsColor(
        color = Color.Transparent,
        darkIcons = useDarkIcons
    )

    // setStatusBarsColor() and setNavigationBarsColor() also exist
}
