自Compose 1.2.0以来，它需要使用padding参数，传入Scaffold内容组合。您应该将其应用于内容中最顶层的容器/视图

@Composable
fun MainScreen() {
    Scaffold(topBar = { AppBar() }) {
        Surface(modifier = Modifier
            .fillMaxSize()
            .padding(it)) // Add this to fix it
         {
            Content()
        }
    }
}

字符串

从我的代码中附加代码片段

Scaffold(
            topBar = {Top(onNavigationIconClick = {scope.launch {drawerState.open()}})},
            bottomBar = { Bottom(navController = navController) },
            content= {
                Column(modifier = Modifier.padding(it)) { // THE MODIFIER PARAMETER DOES THE MAGIC
                    Navigation(navController)
                }
            }
        )

字符串

你可以使用innerPadding，

Scaffold(
    topBar = {
        TopAppBar(
            title = {
                Text(
                    ...
                )
            },
            navigationIcon = {
                IconButton(onClick = { }) {
                    Icon(imageVector = Icons.Default.Menu, contentDescription = "Menu Icon" )
                }
            },
            backgroundColor = colorResource(id = R.color.purple_200),
            contentColor = Color.White,
            elevation = 12.dp
        )
    },

){
    innerPadding ->
    Box(modifier = Modifier.padding(innerPadding)){
        DiaryCard()
    }
}

字符串

您可以：

• 使用topBar = { topAppbar() }添加Scaffold
• 添加一个Column()来 Package 卡片的所有内容

比如说：

Scaffold(topBar = { topAppbar() },
) {
    DiaryCard()
}

字符串
使用：

@Composable
fun DiaryCard(){

    val bs = "filler text,strings,anything "+
            "jadsjjadj adsnjasjd d saasd" +" sadsad asdasd adsasda" +
            "sasdasdas dsa d"

    Column {

        Spacer(modifier = Modifier.padding(top = 6.dp))
        Card(
            modifier = Modifier
                .fillMaxWidth()
                //.background(Color.Red)
                .padding(13.dp),
            shape = MaterialTheme.shapes.small,
            elevation = 5.dp, backgroundColor = Color.White
        ) {
            Column() { //It is important to avoid overlap inside the Card

                Row(modifier = Modifier.padding(bottom = 2.dp)) {

                    Text(
                        text = "29 Sept. 2019", modifier = Modifier
                            .fillMaxWidth(0.75F)
                            .padding(start = 1.5.dp), color = Color.Black
                    )

                }
                Divider()
                Spacer(modifier = Modifier.padding(bottom = 3.dp, top = 2.dp))
                Column(modifier = Modifier.fillMaxWidth()) {
                    Text(text = "today was a good day", color = Color.Black)
                    Spacer(modifier = Modifier.padding(bottom = 3.dp))
                    Text(text = bs, color = Color.Black)
                }

            }
        }
    }
}
