膨胀类 androidx.fragment.app.FragmentContainerView 时出错

Question

我将导航组件更新到2.3.2版本。

在2.3.1版本工作正常

我正在浏览文档，但没有找到有关错误或组件中任何更新的任何内容

Answer 1

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称
