Jetpack compose：设置 ImeAction 不会关闭或更改键盘焦点

我正在使用 Jetpack 撰写1.0.0-alpha07。我制作了一个包含两个的登录屏幕TextField使用其他可组合项进行定制。

然而，设置ImeAction in keyboardOptions似乎不起作用。例如ImeAction.Next不将焦点移动到下一个文本字段。我认为我应该做点什么来使其成为可能，但没有任何文件或文章简短地谈论过ImeOptions。这是我的屏幕代码：

Login可组合：

EmailEdit(onChange = { email.value = it })
PasswordEdit(onChange = { password.value = it })

电子邮件编辑:

@Composable
fun EmailEdit(onChange: (String) -> Unit) {
    val t = remember { mutableStateOf("") }
    TextField(
        value = t.value,
        onValueChange = { value ->
            t.value = value
            onChange(value)
        },
        leadingIcon = { Icon(asset = Icons.Default.Email) },
        label = { Text(text = "Email") },
        maxLines = 1,
        keyboardOptions = KeyboardOptions(
            imeAction = ImeAction.Next, // ** Go to next **
            keyboardType = KeyboardType.Email
        ),
        visualTransformation = VisualTransformation.None
    )
}      errorHint = "Not a valid email"
    )
}

PassEdit:

@Composable
fun PasswordEdit(onChange: (String) -> Unit) {
    val t = remember { mutableStateOf("") }
    TextField(
        value = t.value,
        onValueChange = { value ->
            t.value = value
            onChange(value)
        },
        leadingIcon = { Icon(asset = Icons.Default.Security) },
        label = { Text(text = "Password") },
        maxLines = 1,
        keyboardOptions = KeyboardOptions(
            imeAction = ImeAction.Done, // ** Done. Close the keyboard **
            keyboardType = KeyboardType.Text
        ),
        visualTransformation = PasswordVisualTransformation()
    )
}

去表演Done and Next我应该添加什么代码？

您可以使用

• keyboardOptions：包含配置的软件键盘选项，例如KeyboardType and ImeAction
• keyboardActions当输入服务发出 IME 操作时，会调用相应的回调

For Done:

您可以使用LocalSoftwareKeyboardController https://developer.android.com/reference/kotlin/androidx/compose/ui/platform/LocalSoftwareKeyboardController与键盘交互。

keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
keyboardActions = KeyboardActions(
    onDone = {keyboardController?.hide()}
)

For Next:

keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
keyboardActions = KeyboardActions(
    onNext = { focusRequester.requestFocus() }
)

就像是：

val (focusRequester) = FocusRequester.createRefs()
val keyboardController = LocalSoftwareKeyboardController.current

TextField(
    value = text,
    onValueChange = {
        text = it
    },
    label = { Text("Label") },
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
    keyboardActions = KeyboardActions(
        onNext = { focusRequester.requestFocus() } 
    )
)

TextField(
    value = text,
    onValueChange = {
        text = it
    },
    modifier = Modifier.focusRequester(focusRequester),
    label = { Text("Label") },
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    keyboardActions = KeyboardActions(
        onDone = { keyboardController?.hide() }
    )
)
