我希望将Upcoming文本推到底部，而7 pax文本则保持在顶部。我对该列使用了verticalArrangement = Arrangement.SpaceBetween，但是它没有任何效果，因为列的高度不是完全的。如果我对列使用fillMaxHeight强制它获得完全高度，则整行将获得整个屏幕的高度，这是不需要的。我怎么才能解决这个问题？

@Composable
fun SoFixClientTourCard() {
    Column {
        Row(
            verticalAlignment = Alignment.Top,
            modifier = Modifier
                .background(Color.White)
                .fillMaxWidth()
                .padding(16.dp)
        ) {

            // calendar
            Column(
                horizontalAlignment = Alignment.CenterHorizontally,
                modifier = Modifier
                    .padding(top = 4.dp)
                    .background(MaterialTheme.colors.error)
                    .shadow(1.dp)
                    .padding(horizontal = 8.dp, vertical = 4.dp)
            ) {
                Text("02", fontSize = 14.sp, fontWeight = FontWeight.Bold, color = Color.White)
                Text("OCT", fontSize = 12.sp, fontWeight = FontWeight.Bold, color = Color.White)
            }

            // tour & package name
            Column(
                modifier = Modifier
                    .padding(horizontal = 16.dp)
                    .weight(1f)
            ) {
                Text("Tanguar Haor Tour", style = MaterialTheme.typography.subtitle1, fontWeight = FontWeight.Bold)
                Text(
                    "Couple Non-AC + Single Non-AC + Family Non-AC + Couple AC",
                    style = MaterialTheme.typography.body2,
                    lineHeight = 20.sp,
                    modifier = Modifier.padding(top = 4.dp)
                )
            }

            // FIXME: Align status to the bottom, pax to the top
            // pax & status
            Column(
                horizontalAlignment = Alignment.End,
                verticalArrangement = Arrangement.SpaceBetween,
            ) {
                Text("7 pax", fontSize = XS)
                val status = "Upcoming"
                Text(
                    status,
                    fontSize = XXXS,
                    color = Color.White,
                    modifier = Modifier
                        .padding(top = 4.dp) // top margin
                        .background(
                            when (status.lowercase()) {
                                "upcoming" -> MaterialTheme.colors.primary
                                "cancelled" -> MaterialTheme.colors.error
                                else -> Color.DarkGray
                            }
                        )
                        .padding(horizontal = 8.dp, vertical = 4.dp)
                )
            }
        }
    }
}

谢谢你的帮忙!

您可以将本征测量应用于其父容器，在您的例子中是Row。

将高度(IntrinsicSize.Min)修饰符添加到Row中，将fillMaxHeight()修饰符添加到第3 Column。类似于：

Column {
    Row(
        verticalAlignment = Alignment.Top,
        modifier = Modifier
            .background(Color.White)
            .fillMaxWidth()
            .padding(16.dp)
            .height(IntrinsicSize.Min)
    ) {

        //....
       
        // pax & status
        Column(
            modifier= Modifier.fillMaxHeight(),
            horizontalAlignment = Alignment.End,
            verticalArrangement = Arrangement.SpaceBetween,
        ) {
            //...
        }
    }
}
