Android 活动无法启动：ID未引用此活动内的视图

我试图从导航中导航到

activity\u profile

，但它崩溃了，我在catlog中得到一个错误。我检查了我的代码是否有拼写错误或错误，但我一直遇到以下错误消息：

我试着看看是否有其他人也有同样的问题，但主要是关于

navController

在

setContentView（）之后没有被调用。但是在我的例子中，我在
setContentView（）之后调用它。是什么导致了这个问题

drawerLayout = findViewById(R.id.drawer_layout)

activity_profile.xml没有抽屉布局id，因此您的
@+id/nav_host_片段在
activity_profile.xml
中的哪里？我没有看到它。它应该在
android:id=“
”里面吗？你需要有一个
NavHostFragment
和这个id…是的。你认为
findNavController
会做什么？它属于
android:id=“”
？
