如何通过 Jetpack Compose 使用 Material TextField Composable 的 readOnly 属性

Question

我的用例是，我有一个表单，其中一些字段是手动填写的，其他字段将用户带到一个屏幕，他们可以在其中在一个大列表中搜索他们想要的值。仅接受用户输入的字段工作正常，但是当我尝试将属性添加readOnly = true到TextField可组合项时，出现以下错误：

\n

None of the following functions can be called with the arguments supplied.\nTextField(TextFieldValue, (TextFieldValue) \xe2\x86\x92 Unit, Modifier = ..., TextStyle = ..., (() \xe2\x86\x92 Unit)? = ..., (() \xe2\x86\x92 Unit)? = ..., (() \xe2\x86\x92 Unit)? = ..., (() \xe2\x86\x92 Unit)? = ..., Boolean = ..., VisualTransformation = ..., KeyboardOptions = ..., Boolean = ..., Int = ..., (ImeAction, SoftwareKeyboardController?) \xe2\x86\x92 Unit = ..., (SoftwareKeyboardController) \xe2\x86\x92 Unit = ..., InteractionState = ..., Color = ..., Color = ..., Color = ..., Color = ..., Shape = ...) defined in androidx.compose.material\nTextField(String, (String) \xe2\x86\x92 Unit, Modifier = ..., TextStyle = ..., (() \xe2\x86\x92 Unit)? = ..., (() \xe2\x86\x92 Unit)? = ..., (() \xe2\x86\x92 Unit)? = ..., (() \xe2\x86\x92 Unit)? = ..., Boolean = ..., VisualTransformation = ..., KeyboardOptions = ..., Boolean = ..., Int = ..., (ImeAction, SoftwareKeyboardController?) \xe2\x86\x92 Unit = ..., (SoftwareKeyboardController) \xe2\x86\x92 Unit = ..., InteractionState = ..., Color = ..., Color = ..., Color = ..., Color = ..., Shape = ...) defined in androidx.compose.material\n

\n

我假设此错误与我的参数与提供的覆盖不匹配有关TextField，但我似乎无法在文档中找到任何内容来了解​​如何使用此属性，而不是简单地为其提供一个Boolean值。我正在看这里寻找文档。

代码是：

我正在使用androidx.compose.material:material:1.0.0-alpha09Compose Material 包的版本alpha09我的其余 compose 依赖项。

Answer 1

readOnly在更新我的所有 compose 依赖项1.0.0-alpha10，然后使缓存无效并重新启动 Android Studio后，我能够使用该属性。

我发现这个属性被引入了，alpha10这就是我之前收到错误的原因。

以下是我用来得出这个结论的链接：

• 发行说明
• 拉取请求添加该功能
