沉浸式(侵入式)状态栏

效果图：

 

1、代码加入：WindowCompat.setDecorFitsSystemWindows(window, false)

ComposeTestTheme {
                WindowCompat.setDecorFitsSystemWindows(window, false)
                Greeting("Android")
            }

2、沉浸式(侵入式)主题：

@Composable
fun ComposeTestTheme(
    darkTheme: Boolean = isSystemInDarkTheme(),
    // Dynamic color is available on Android 12+
    dynamicColor: Boolean = true,
    content: @Composable () -> Unit
) {
    val colorScheme = when {
        dynamicColor && Build.VERSION.SDK_INT >= Build.VERSION_CODES.S -> {
            val context = LocalContext.current
            if (darkTheme) dynamicDarkColorScheme(context) else dynamicLightColorScheme(context)
        }
        darkTheme -> DarkColorScheme
        else -> LightColorScheme
    }
    val view = LocalView.current
    if (!view.isInEditMode) {
        SideEffect {
            (view.context as Activity).window.statusBarColor = Color.Transparent.toArgb() //透明
            ViewCompat.getWindowInsetsController(view)?.isAppearanceLightStatusBars = darkTheme
        }
    }

    MaterialTheme(
        colorScheme = colorScheme,
        typography = Typography,
        content = content
    )
}

3、

@Composable
fun Greeting(name: String) {
    Box(
        modifier = Modifier
            .size(200.dp)
            .background(Color.Red),
        contentAlignment = Alignment.Center

    ) {
        Text(text = "Hello from Compose", color = Color.White, fontSize = 20.sp)
    }
    
}
