To improve the efficiency of displaying long lists in Android, the following methods are usually used:

  • RecyclerView with ViewHolder: allows reusing list items, reducing memory load and increasing performance.
  • Pagination: load and display data in parts rather than the entire list at once.
  • Differential update (DiffUtil): update only the changed list items, not the entire list.
  • Optimization of item layout: use simple and lightweight layouts, avoid nested and heavy components.
  • Asynchronous data and image loading: to avoid blocking the UI thread.

Example of using RecyclerView with ViewHolder:

class MyAdapter(private val items: List<String>) : RecyclerView.Adapter<MyAdapter.ViewHolder>() {
    class ViewHolder(val textView: TextView) : RecyclerView.ViewHolder(textView)

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        val textView = LayoutInflater.from(parent.context)
            .inflate(android.R.layout.simple_list_item_1, parent, false) as TextView
        return ViewHolder(textView)
    }

    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        holder.textView.text = items[position]
    }

    override fun getItemCount() = items.size
}
