Nullpointerexception на ActionProcessButton

Question

При попытке запустить код я получаю нулевой указатель на моем ActionProcessButton и, похоже, не могу найти решение.

Это мой код:

public class ChangePasswordFragment extends Fragment {

    @BindView(R.id.old_password)
    EditText oldPasswordText;
    @BindView(R.id.new_password)
    EditText newPasswordText;
    @BindView(R.id.connfirm_password)
    EditText confirmPasswordText;
    @BindView(R.id.done_button)
    ActionProcessButton doneButton;
    @BindView(R.id.delete_button)
    ActionProcessButton deleteButton;
    @BindView(R.id.layout)
    LinearLayout layout;
    @BindView(R.id.animation_view)
    LottieAnimationView animationView;

    private String mToken;
    private Handler mHandler;
    private Activity mActivity;
    private SharedPreferences mSharedPreferences;
    private View mView;
    private static final String LOG_TAG = Login.class.getSimpleName();

    public ChangePasswordFragment() {
        //required public constructor
    }

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

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        mActivity = (Activity) context;
    }
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater,
                             @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        mView = inflater.inflate(R.layout.fragment_settings, container, false);
        ButterKnife.bind(this, mView);

        mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(mActivity);

        mToken = mSharedPreferences.getString(USER_TOKEN, null);
        mHandler = new Handler(Looper.getMainLooper());

        doneButton.setMode(ActionProcessButton.Mode.ENDLESS);
        doneButton.setOnClickListener(v -> {
            hideKeyboard();
            if (checkEmptyText())
                checkPasswordMatch();
        });

        deleteButton.setOnClickListener(v -> {
            deleteAccount();
        });


        return mView;
    }

            </LinearLayout>
        </LinearLayout>

    </android.support.design.widget.CoordinatorLayout>
</RelativeLayout>

Я реализовал необходимые библиотеки и использовал правильный идентификатор.И насколько я знаю, это не должно быть проблемой, что я реализовал это в методе oncreateView().

Ошибка, которую я получаю, гласит:

java.lang.NullPointerException: Attempt to invoke virtual method 'void com.dd.processbutton.iml.ActionProcessButton.setMode(com.dd.processbutton.iml.ActionProcessButton$Mode)' on a null object reference

Если вы укажете мне правильное направление, это будет высоко оценено.
