How can you update the state of a single checkbox element inside a RecyclerView without re-rendering the entire list?

To update the state of a single checkbox in RecyclerView without redrawing the entire list, you need to update only the corresponding item.

Main approaches:

• Use the notifyItemChanged(position) method of the adapter to redraw only the item at the specified position.
• Properly set the checkbox state from the data model in onBindViewHolder to avoid incorrect display when reusing ViewHolder.

Example:

// When the checkbox state changes
checkbox.setOnCheckedChangeListener((buttonView, isChecked) -> {
    dataList.get(position).setChecked(isChecked); // update the model
    adapter.notifyItemChanged(position); // update only this item
});

This way, RecyclerView will update only the necessary item without affecting others.
