【问题讨论】：

你会想要包含整个堆栈跟踪 - 它通常是最重要的最底层的“原因”。
这能回答你的问题吗？ ClassNotFoundException when using androidx.fragment.app.FragmentContainerView
@SamChen 不，这是不同的错误
我有同样的问题（ClassNotFoundException 和 Error inflating class androidx.fragment.app.FragmentContainerView 在我的日志中）。它出现在我在 nav_graph 文件中添加 1 个参数之后。当我发表评论时，一切正常。很奇怪。参数是一个自定义的 Serializable 类

标签： android kotlin android-architecture-navigation

【解决方案1】：

如果您使用的是Jetpack Compose，请将MainActivity 扩展为AppCompatActivity 而不是CompatActivity

【讨论】：

【解决方案2】：

我遇到了同样的问题，我发现 Android Studio 没有在导航图中添加名称标签。因此，在导航图 xml 中添加名称标签对我有用。

在 nav_graph.xml 中

<fragment
    android:id="@+id/loginFragment"
    android:name="com.example.MyApp.fragments.LoginFragment"
    android:label="fragment_login"
    tools:layout="@layout/fragment_login">

或者如果您不确定，请切换到设计并在右侧的属性选项卡中从下拉列表中选择类名

【解决方案3】：

首先确保您已将 ID 添加到导航图和片段容器视图。还要检查片段（声明为起始目标）没有任何实例化问题。

【解决方案4】：

导航组件 2.3.2 版本也存在同样的问题。

在2.3.1版本可以正常使用
