Answer from AI

The onBindViewHolder method binds data to the interface elements displayed in a specific ViewHolder. This method is called for each list item when the RecyclerView wants to display or update content.

Main actions inside onBindViewHolder:

  • Retrieving data from the source (e.g., from a list of models) based on position.
  • Filling the widgets inside the ViewHolder with this data (setting text, images, etc.).
  • Setting up event handlers if needed.

Example:

override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
    val item = dataList[position]
    holder.textView.text = item.title
    holder.imageView.setImageResource(item.imageResId)
}
