Unexpected Behavior with Custom RecyclerView Item Animations in Android 14

android recyclerview animation kotlin

I'm having trouble with I'm following best practices but I need help solving I've looked through the documentation and I'm still confused about I'm implementing a custom animation for items in a `RecyclerView`, and I'm experiencing unexpected behavior in Android 14. The animation works perfectly during item insertion, but when I try to remove an item, the animation triggers, but the item does not get removed from the list. Instead, it briefly flickers back before disappearing. My `RecyclerView` is using a `ListAdapter` with `DiffUtil` to handle updates efficiently. Here's a snippet of my code: ```kotlin class MyAdapter : ListAdapter<MyItem, MyViewHolder>(MyDiffCallback()) { override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder { val view = LayoutInflater.from(parent.context).inflate(R.layout.item_layout, parent, false) return MyViewHolder(view) } override fun onBindViewHolder(holder: MyViewHolder, position: Int) { holder.bind(getItem(position)) } } fun removeItem(position: Int) { val currentList = currentList.toMutableList() currentList.removeAt(position) submitList(currentList) { notifyItemRemoved(position) } } ``` I have tried using `notifyItemRemoved()` as well as ensuring that the list is correctly updated prior to calling `submitList()`, but the flickering still occurs. I’ve also confirmed that my animations are defined in XML and are being correctly applied. The relevant animation code looks like this: ```xml <set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_decelerate_interpolator"> <scale android:fromXScale="1" android:toXScale="0" android:fromYScale="1" android:toYScale="0" android:pivotX="50%" android:pivotY="50%" android:duration="300" /> </set> ``` Is there a specific method I might be missing to ensure the item is fully removed without flickering? I've also checked for any ongoing animations that might be conflicting, but everything seems to be in order. Any insights would be greatly appreciated! This is part of a larger service I'm building. How would you solve this? This is my first time working with Kotlin 3.11. I'm open to any suggestions. Could someone point me to the right documentation? Any feedback is welcome!
