您可以使用 BasicTextField 来控制它。

            var value by rememberSaveable { mutableStateOf("") }

            BasicTextField(

                cursorBrush = SolidColor(Color.White),
                value = value,
                onValueChange = { value = it },
                textStyle = TextStyle(color = Color.White),
                decorationBox = { innerTextField ->

                    Row(modifier = Modifier.fillMaxWidth()) {
                        if (value.isEmpty()) {
                            Text(text = "Placeholder", color = Color.White)
                        }
                    }

                    innerTextField()
                }
            )
