我正在尝试LazyColumn在警报对话框中显示一个，以便用户可以在项目列表之间进行选择，然后单击它。警报对话框将毫无问题地显示，我可以单击屏幕上的任何项目并将其关闭，但是一旦我尝试在项目之间滚动，它将给出以下错误：

这是AlertDialog代码：

AlertDialog(
    onDismissRequest = { showDialog.value = false },
    modifier = Modifier.fillMaxHeight(.80f),
    text = {
        LazyColumn{
            items(30){ i ->
                Text(text = i.toString())
            }
        }
    },
    buttons = {
            Button(onClick = { /*TODO*/ }) {
                Text(text = "Cancel")
            }
    }
)

虽然我发现如果我使用 Material3 库滚动不再是问题，但我也遇到了同样的问题：

实现“androidx.compose.material3:material3:1.0.0-alpha03”

AlertDialog(
        onDismissRequest = { },
        modifier = Modifier.fillMaxHeight(0.8f),
        text = {
            LazyColumn() {
                items(30) { i ->
                    Text(text = i.toString())
                }
            }
        },
        dismissButton = {
            Button(onClick = { /*TODO*/ }) {
                Text(text = "Cancel")
            }
        }
    )

确保导入：

导入 androidx.compose.material3.AlertDialog

我不知道这是否是正确的答案，但我希望它在任何情况下都有帮助。
