可以给Dialog中的TextField添加onImeActionPerformed监听器。当用户在输入完成后点击键盘上的“完成”键时，它会被调用。在这个监听器中，我们可以指示对话框的取消。

示例代码：

@Composable fun ComposeDialog() { val showDialog = remember { mutableStateOf(false) } val text = remember { mutableStateOf("") } if (showDialog.value) { Dialog( onDismissRequest = { showDialog.value = false } ) { Column { Text(text = "Enter your name")

            TextField(
                value = text.value,
                onValueChange = {
                    text.value = it
                },
                modifier = Modifier
                    .fillMaxWidth(),
                keyboardOptions = KeyboardOptions(
                    imeAction = ImeAction.Done
                ),
                keyboardActions = KeyboardActions(
                    onDone = {
                        showDialog.value = false
                    }
                )
            )
    
            Button(
                onClick = {
                    showDialog.value = false
                }
            ) {
                Text(text = "Ok")
            }
        }
    }
}
Button(onClick = {
    showDialog.value = true
}) {
    Text(text = "Show dialog")
}

}
