Jetpack Compose Dialog切换内容后无法动态更新高度的问题求助

问题根源在于你给Column设置了.height(IntrinsicSize.Min)——这个修饰符会把Column的高度固定为初始渲染时的最小固有高度，后续切换选项导致内容变化时，高度不会重新计算。再加上Card没有明确设置自适应高度，进一步限制了Dialog的高度调整。

按以下两步修改即可解决：

1. 移除Column的固定高度限制：删掉.height(IntrinsicSize.Min)，让Column根据内部内容自动计算高度。
2. 给Card添加自适应高度修饰符：在Card的modifier里加上.wrapContentHeight()，确保Card能随内容伸缩。

修改后的完整代码：

var type = remember { mutableStateOf("Adult") }
Dialog(
    onDismissRequest = { onDismiss() }, 
    properties = DialogProperties(
        dismissOnBackPress = true, 
        dismissOnClickOutside = true
    ),
) {
    Card(
        shape = RoundedCornerShape(12.dp),
        modifier = Modifier
            .fillMaxWidth()
            .wrapContentHeight(), // 添加自适应高度
        elevation = 8.dp
    ) {
        Column(
            modifier = Modifier
                .background(Color.White)
                .padding(top = 10.dp), // 移除IntrinsicSize.Min限制
            horizontalAlignment = Alignment.CenterHorizontally
        ) {

            Row() {
                SemiBoldTextSmall(
                    text = "Adult",
                    textColor = if (type.value == "Adult") Color.Black else Color.LightGray,
                    fontSize = 14.sp,
                    modifier = Modifier
                        .fillMaxWidth()
                        .padding(10.dp)
                        .weight(1f)
                        .clickable {
                            type.value = "Adult"
                        })
                SemiBoldTextSmall(text = "Kids",
                    textColor = if (type.value == "Kids") Color.Black else Color.LightGray,

                        .clickable {
                            type.value = "Kids"
                        })

                        color = Color.LightGray,
                        shape = RoundedCornerShape(10.dp)
                    )
                    .wrapContentSize(),
                    placeholder = "Name",
                    text = "",
                    textSize = 14.sp,
                    onValueChange = {

                    })

                EditBox(modifier = Modifier
                    .padding(top = 10.dp, start = 20.dp, end = 20.dp)
                    .background(color = Color.White, shape = RoundedCornerShape(10.dp))
                    .border(
                        width = 1.dp,
                        color = Color.LightGray,
                        shape = RoundedCornerShape(10.dp)
                    )
                    .wrapContentSize(),
                    placeholder = "Mobile Number",
                    text = "",
                    textSize = 14.sp,
                    keyboardType = KeyboardType.Number,
                    onValueChange = {
                    })
            }

            SemiBoldTextSmall(text = "+ ADD",
                textColor = Color.White,
                fontSize = 14.sp,
                modifier = Modifier
                    .padding(top = 30.dp)
                    .fillMaxWidth()
                    .background(color = greenColor, shape = RectangleShape)
                    .padding(10.dp)
                    .clickable {
                        onSubmit()
                    })
        }
    }
}

额外注意：如果你的EditBox组件内部有固定高度设置，也需要确保它是自适应的，否则可能依然会限制整体高度。
