I want to change/update my note so i need to add setOnClickListener method but i don't know which element that should be clicked. I tried to use setOnClickListener on recycler view but it did not work

Answer 1

in your adapter class you can put viewholder class that implement onClickListener

public class YourClassAdapter extends RecyclerView.Adapter<YourClassAdapter.YourViewHolder> {

    //your code

    class YourViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
       
        TextView price;
    
        public YourViewHolder(@NonNull View itemView) {
            super(itemView);
            //change to your view id
            price = itemView.findViewById(R.id.txtprecio1);
    
            itemView.setOnClickListener(this);
    
        }
    
    
      @Override
          public void onClick(View view) {
           //do something when clicked
       }
    }
}

then put your code you want on function onClick
