Android приложение перестало запускатся

Я не понимаю, у меня есть Fragment я в него перенес код из Activity, почему при нажатии приложение крашится. И можете подсказать как что-то понимать в логах. Я вроде бы смотрю слова знакомые а из-за чего ошибка выскакивает не пойму.

Java

public class ItemFiveFragment extends Fragment implements View.OnClickListener
{
    private com.github.aakira.expandablelayout.ExpandableRelativeLayout expandableLayout1;
    private com.github.aakira.expandablelayout.ExpandableRelativeLayout expandableLayout2;
    private com.github.aakira.expandablelayout.ExpandableRelativeLayout expandableLayout3;
    private com.github.aakira.expandablelayout.ExpandableRelativeLayout expandableLayout4;

    public static ItemFiveFragment newInstance()
    {
        return new ItemFiveFragment();
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        return inflater.inflate(R.layout.fragment_item_setting, container, false);
    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState)
    {
        expandableLayout1 = requireView().findViewById(R.id.expandableLayout1);
        expandableLayout1.toggle(); // toggle expand and collapse

        expandableLayout2 = requireView().findViewById(R.id.expandableLayout2);
        expandableLayout2.toggle(); // toggle expand and collapse

        expandableLayout3 = requireView().findViewById(R.id.expandableLayout3);
        expandableLayout3.toggle(); // toggle expand and collapse

        expandableLayout4 = requireView().findViewById(R.id.expandableLayout4);
        expandableLayout4.toggle(); // toggle expand and collapse
    }
    public void onClick(View v)
    {
    }

}
