ulkeler.add("TÜRKİYE");
ulkeler.add("RUSYA");
ulkeler.add("FRANSA");
ulkeler.add("İNGİLTERE");
ulkeler.add("JAPONYA");
ulkeler.add("ALMANYA");


ArrayList<String> ulkelertwo = new ArrayList<>();
ulkeler.add("TÜRKİYEw");
ulkeler.add("RUSYAw");
ulkeler.add("FRANSAw");
ulkeler.add("İNGİLTEREw");
ulkeler.add("JAPONYAw");
ulkeler.add("ALMANYAw");

adapter = new MyAdapter(this,ulkeler,ulkelertwo);
rv.setAdapter(adapter);

onBindViewHolder

public void onBindViewHolder(@NonNull one holder, int position) {
    String ulke = ulkelerListe.get(position);
    String ulketwo = ulkelerListetwo.get(position);

    holder.textView.setText(ulke);
    holder.textViewtwo.setText(ulketwo);



}

getItemCount public int getItemCount() {

    return ulkelerListe.size()+ulkelerListetwo.size();
}

Size of GetItemCount() is more than the list itemspassed for binding to recycler view. During getting the data at index which is not in the list causes exception.

To make this working in your approach, you have to ensure two things:

ulkeler and ulkelertwo must have same size.
Return ulkelerListe.size only from getItemCount()
