java.lang.IndexOutOfBoundsException: Index: 25, Size: 25

Answer 1

You have two lists of data to pull from, but you arbitrarily pull from both lists using the position , which may be bigger than either of them since getItemCount() returns the combined size of both lists.

You need to decide which list to pull from based on how big the position is. Something like this:

override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
    if (position < feedback.size) {
        val feedbackItem = feedback[position]
        itemView.tv_question.text = feedbackItem.questions
        //...
    } else {
        val answersItem = answerss[position - feedback.size]
        holder.itemView.cb_answer.text = answersItem
        //...
    }

}

Since you seem to be using a common layout for both types of list item, you will also need to possibly hide and show parts of the layout in the two respective branches of this if/else statement.
