How to implement guide with custom view inflation leading to nullpointerexception in fragment on android 14
Quick question that's been bugging me - I've searched everywhere and can't find a clear answer... I'm reviewing some code and I'm working with a `NullPointerException` when trying to inflate a custom view in my `Fragment` on Android 14. The custom view is set up in XML and I'm inflating it in the `onCreateView` method of my fragment. Here's the relevant part of my code: ```kotlin class MyFragment : Fragment() { private lateinit var myCustomView: MyCustomView override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View? { val view = inflater.inflate(R.layout.fragment_my, container, false) myCustomView = view.findViewById(R.id.custom_view) return view } } ``` In my layout file `fragment_my.xml`, I have the following: ```xml <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <com.example.MyCustomView android:id="@+id/custom_view" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout> ``` The `NullPointerException` occurs when I'm trying to access a method on `myCustomView` in `onViewCreated`. I've tried debugging and ensured that the `View` is being inflated correctly. The exception stack trace points to the line where I'm calling a method on `myCustomView`, indicating that it's still null. Here's how I'm accessing it: ```kotlin override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) myCustomView.someMethod() // This line throws NullPointerException } ``` I've also checked the lifecycle of the fragment, and I'm confident that `onCreateView` is being called before `onViewCreated`. The only thing I can think of is that the `Fragment` is being recreated due to a configuration change, but I have not set any specific configuration changes to handle. Could this be a question with how I'm inflating the `CustomView`, or do I need to handle the fragment's lifecycle differently? Any guidance would be appreciated! I'm open to any suggestions. The project is a REST API built with Kotlin. I appreciate any insights! The project is a service built with Kotlin. What's the correct way to implement this?
