启用safe-args插件后无法从数据绑定获取根视图 [英] Can't get Root View from Data Binding after enabling safe-args plugin

问题描述

我正在使用dataBinding在Android应用程序上工作，当前正在尝试添加safe-args插件，但是启用该插件后，我无法再通过binding.root获取根视图-Android Studio给出了错误消息:

I'm working on an Android app using dataBinding and am currently trying to add the safe-args plugin, but after enabling the plugin, I can no longer get the root view via binding.root - Android Studio gives the error:

Unresolved Reference
None of the following candidates is applicable because of a receiver type mismatch:
* internal val File.root: File defined in kotlin.io

如何使数据绑定和safe-args一起玩得开心?

How can I get databinding and safe-args to play nice together?

请注意，虽然代码片段位于Kotlin中，但我会很高兴获得Java答案.对Java不太满意，但我可以轻松阅读并翻译.

Note that while the code snippet is in Kotlin I will happily take Java answers. Not as comfortable in Java but I can easily read it and translate it.

我无法通过谷歌搜索错误消息和安全参数"来找到其他遇到相同问题的人.我首先尝试使用以下Android文档中列出的类路径: https://developer. android.com/guide/navigation/navigation-pass-data

I haven't been able to find anyone else with the same problem by Googling the error message and "safe args". I tried first with the classpath listed in the Android docs here: https://developer.android.com/guide/navigation/navigation-pass-data

classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.1.0"

然后还找到了一个建议我使用的教程:

And then also found a tutorial suggesting I use:

classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0-alpha07"

两者都有相同的问题:binding.root在激活插件时出现错误

Both had the same issue: binding.root gave an error with the plugin activated

这是我的片段的onCreateView().该返回行在未启用safe-args时正常工作，而在启用后则不起作用

Here is my onCreateView() for my fragment. That return line works properly when safe-args isn't enabled and doesn't work when it is enabled

   override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    binding = DataBindingUtil.inflate(inflater, R.layout.fragment_encoder, container, false)

    return binding.root
}

对于解决或理解此问题的任何帮助，深表感谢！

Any help solving or understanding this problem is most appreciated!

推荐答案

我遇到了同样的问题， 对我来说是如此有线 但只要重命名布局即可再次使用， 尝试:D

I have the same issue, it's so wired for me, but just rename the layout will work again, try to it :D
