        public MyViewHolder(View itemView) {

            textShow = (TextView) itemView.findViewById(R.id.tvphrase);
        }
    }




}

Maxouille :

ListofItem is an Array not a List in Java.

You should use:

listOfItems[holder.getLayoutPosition()];

And you should check if the index of the item you are trying to access at `` is not out of bounds:

if (holder.getLayoutPosition() < listOfItems.length) {
    listOfItems[holder.getLayoutPosition()];
}
else {
    Log.d("TAG", "Error: index out of bounds");
}

To access members in Java:

• For an Array : your_array[index]
• For a List : your_list.get(index)
