出于某種原因，在嘗試在 Compose 中創建 TextField 時，我經常遇到引數問題，例如：
// this is perfectly fine
@Composable
fun Username() {
val emailState = remember{ mutableStateOf(TextFieldValue())}
TextField(
modifier = Modifier.fillMaxWidth(),
label = { Text(text = stringResource(R.string.username_label))},
value = emailState.value,
onValueChange = { emailState.value = it },
shape = RoundedCornerShape(8.dp),
keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Email),
)
}
但是，如果我嘗試插入顏色值，一切都會崩潰：
@Composable
fun Username() {
val emailState = remember{ mutableStateOf(TextFieldValue())}
TextField(
modifier = Modifier.fillMaxWidth(),
label = { Text(text = stringResource(R.string.username_label))},
value = emailState.value,
onValueChange = { emailState.value = it },
shape = RoundedCornerShape(8.dp),
keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Email),
color = TextFieldDefaults.textFieldColors(
unfocusedIndicatorColor = Color.Transparent,
focusedIndicatorColor = Color.Transparent
)
)
}
無論我在此處的引數串列中的何處添加“顏色”，它都不起作用。我回來了：
None of the following functions can be called with the arguments supplied.
我根本不了解這里的建構式，我什至將我的代碼更改為與在線其他人更相似，但仍然得到相同的錯誤。

TextField 沒有color引數。你必須colors改用
