【速记】汐洛安卓在 kotlin compose 中设置全屏模式的方法

这方面网上的资料很乱，简单来说就三步：

首先定义?

fun Activity.toggleFullScreen(fullScreen: Boolean) {
    val windowInsetsController = window.insetsController
    if (fullScreen) {
        val params = window.attributes
        params.layoutInDisplayCutoutMode =
            WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES
        window.attributes = params
        windowInsetsController?.systemBarsBehavior =
            WindowInsetsController.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE // 当用户从上往下滑动时，系统将短暂出现一个半透明的
        windowInsetsController?.hide(WindowInsets.Type.statusBars())
        windowInsetsController?.hide(WindowInsets.Type.systemBars())
        windowInsetsController?.hide(WindowInsets.Type.navigationBars())
        windowInsetsController?.hide(WindowInsets.Type.captionBar())
        windowInsetsController?.hide(WindowInsets.Type.systemGestures())
    } else {
        val params = window.attributes
        params.layoutInDisplayCutoutMode =
            WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT
        window.attributes = params
        windowInsetsController?.systemBarsBehavior =
            WindowInsetsController.BEHAVIOR_DEFAULT
        windowInsetsController?.show(WindowInsets.Type.statusBars())
        windowInsetsController?.show(WindowInsets.Type.systemBars())
        windowInsetsController?.show(WindowInsets.Type.navigationBars())
        windowInsetsController?.show(WindowInsets.Type.captionBar())
        windowInsetsController?.show(WindowInsets.Type.systemGestures())
    }
}
​

在 compose 函数中：

val Lcc = LocalContext.current
    var isFullScreen by remember { mutableStateOf(false) }
    LaunchedEffect(isFullScreen) {
        val activity = Lcc as Activity
        activity.toggleFullScreen(isFullScreen)
    }
​

最后提供 UI 即可：

DropdownMenuItem(
            text = { Text(if (isFullScreen) "正常模式" else "全屏模式") },
            leadingIcon = { Icon(Icons.TwoTone.FitScreen, contentDescription = null) },
            onClick = {
                onDismiss()
                isFullScreen = !isFullScreen
            },
        )
​
