Issues with RecyclerView Scroll Performance When Using View Binding and DiffUtil
I'm sure I'm missing something obvious here, but I recently switched to I'm trying to implement I'm updating my dependencies and I'm facing performance issues with my `RecyclerView` that is populated using `View Binding` and `DiffUtil`. Even with only a few items (around 50), the scrolling feels jittery, especially when the list updates. I've followed the best practices for using `DiffUtil`, but the performance is still not optimal. Here's how I've set it up: In my `Adapter`, I have the following: ```kotlin class MyAdapter : ListAdapter<MyDataModel, MyViewHolder>(MyDiffCallback()) { override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder { val binding = ItemLayoutBinding.inflate(LayoutInflater.from(parent.context), parent, false) return MyViewHolder(binding) } override fun onBindViewHolder(holder: MyViewHolder, position: Int) { val item = getItem(position) holder.bind(item) } } ``` In my `ViewHolder`: ```kotlin class MyViewHolder(private val binding: ItemLayoutBinding) : RecyclerView.ViewHolder(binding.root) { fun bind(item: MyDataModel) { binding.textView.text = item.name // Additional binding logic } } ``` The `DiffUtil` callback looks like this: ```kotlin class MyDiffCallback : DiffUtil.ItemCallback<MyDataModel>() { override fun areItemsTheSame(oldItem: MyDataModel, newItem: MyDataModel): Boolean { return oldItem.id == newItem.id } override fun areContentsTheSame(oldItem: MyDataModel, newItem: MyDataModel): Boolean { return oldItem == newItem } } ``` I call `submitList` on the adapter every time the data changes. However, I notice significant lag when new data is submitted, with the following log message appearing in the Logcat: ``` E/RecyclerView: No adapter attached; skipping layout ``` I've tried optimizing the layout XML by removing unnecessary nesting and using `ConstraintLayout`, but the issue persists. I also ensured that the RecyclerView is set to `setHasFixedSize(true)`, but this hasn’t impacted performance. Are there any additional optimizations or best practices I might be missing? Any help would be appreciated! The project is a desktop app built with Kotlin. For reference, this is a production mobile app. What would be the recommended way to handle this? Thanks in advance!
