android-jetpack-compose - 滚动 LazyColumn 项目使 ScaffoldBottomSheet 折叠

Question

我将使用jetpack compose 实现一个屏幕，其中包含底部工作表内容中的aScaffoldBottomSheet和a 。LazyColumn我还希望底部工作表的高度是固定的，用户不能折叠它。为了做到这一点，我禁用了工作表手势并为600.dp底部工作表的内容提供高度。但是当我滚动惰性列的项目时，底部工作表会向下滚动并最终折叠。

这是我的代码：

@ExperimentalMaterialApi
@Composable
fun TestScreen(
    testViewModel: TestViewModel = hiltViewModel()
) {
    val bottomSheetScaffoldState = rememberBottomSheetScaffoldState(
        bottomSheetState = rememberBottomSheetState(
            BottomSheetValue.Expanded
        )
    )

    BottomSheetScaffold(
        scaffoldState = bottomSheetScaffoldState,
        sheetContent = {
            Box(modifier = Modifier.fillMaxWidth().height(600.dp)) {
                LazyColumn() {
                    items(20) {
                        Text(text = "this is for test", modifier = Modifier
                            .padding(start = 20.dp, top = 20.dp)
                            .fillMaxWidth()
                            .height(50.dp))
                    }
                }
            }
        },
        sheetPeekHeight = 0.dp,
        sheetShape = RoundedCornerShape(topEnd = 52.dp, topStart = 52.dp),
        backgroundColor = AppColor.ThemeColor.BACKGROUND,
        sheetGesturesEnabled = false
    ) {

    }
}
