我跟随添加组件到您的项目,但没有解决我的问题.

项目:build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'

allprojects {

当我尝试使用 Safe Args 插件从一个片段跳转到另一个片段时，编译器显示“未解析的引用：VideoFragmentDirections”。我已经设置了安全参数的类路径和依赖项，并且 VideoFragmentArgs 已正确生成。kotlin_version = '1.3.50' navigation-safe-args-gradle-plugin:2.1.0 在我的 xml 中

<fragment
        android:id="@+id/nav_home"
        android:name="example.ui.home.HomeFragment"
        android:label="@string/menu_home"
        tools:layout="@layout/fragment_home" >
        <action
            android:id="@+id/action_nav_home_to_videoFragment"
            app:destination="@id/videoFragment"
            app:popUpTo="@+id/nav_home"/>
    </fragment>
<fragment
        android:id="@+id/videoFragment"
        android:name="example.ui.videoui.VideoFragment"
        android:label="VideoFragment" >
        <argument
            android:name="id"
            app:argType="long"
            android:defaultValue="0L" />
    </fragment>

在 HomeFragment.ky 中

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        val videoViewModel = ViewModelProviders
            .of(this)
            .get(HomeViewModel::class.java)
        val adapter = video_list.adapter!! as PlaylistAdapter
        videoViewModel.videos.observe(this, Observer<List<Video>> {
            adapter.submitList(it)
            adapter.onItemClickListener = View.OnClickListener { v ->

                val viewHolder = v.tag as RecyclerView.ViewHolder
