Save CheckBox state

I am attempting to save the state of checkboxes in a fragment. I have a test to make sure that the checkbox state is restored on an orientation change. The test fails because the checkbox state is not restored. However, when I step through the code during a test, it appears to work the way I expect. enabledFields has the correct values in onPause(), onSaveInstanceState() and onCreate(). The correct element of filterOptions is set to be checked. However, it doesn't appear as checked on the screen. What am I missing here?

FilterCardsTest

@RunWith(AndroidJUnit4.class)
public class FilterCardsTest {
    @Rule
    public ActivityTestRule<FragmentTestActivity> activityTestRule =
            new ActivityTestRule<>(FragmentTestActivity.class);

    private static final int[] IDS =
            {R.id.brand, R.id.year, R.id.number, R.id.player_name, R.id.team};

    private FragmentTestActivity activity = null;
    private UiDevice device;

    @Before
    public void setUp() throws Exception {
        activity = activityTestRule.getActivity();
        activity.replaceFragment(new FilterCards());
        device = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
    }

    @After
    public void tearDown() throws RemoteException {
        device.setOrientationNatural();
    }

    @Test
    public void testSaveInstanceStateBrand() throws RemoteException {
        this.testSaveInstanceState(R.id.brand);
    }

    private void testSaveInstanceState(int filterId) throws RemoteException {
        this.testCheckBox(filterId);
        device.setOrientationLeft();
        onView(withId(filterId))
                .check(matches(isChecked()));
        onView(allOf(withParent(withId(filterId)), instanceOf(EditText.class)))
                .check(matches(isEnabled()));

        for (int id : IDS) {
            if (id != filterId) {
                onView(withId(id)).check(matches(isNotChecked()));
            }
        }
    }
}

FilterCards

public class FilterCards extends Fragment {
    private static final String INPUT_EXTRA = "input";

    private static final String[] EXTRAS = {BRAND_EXTRA, YEAR_EXTRA, NUMBER_EXTRA,
            PLAYER_NAME_EXTRA, TEAM_EXTRA};

    @InjectViews({R.id.brand, R.id.year, R.id.number, R.id.player_name, R.id.team})
    List<FilterOptionView> filterOptions;
    private ArrayList<Integer> enabledFields = new ArrayList<>();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.filter_cards, container, false);
        ButterKnife.inject(this, view);

        // restore input fields state
        if (savedInstanceState != null) {
            ArrayList<Integer> enabledFields = savedInstanceState
                    .getIntegerArrayList(INPUT_EXTRA);

            Log.d(TAG, "enabledField=" + enabledFields);

            if (enabledFields != null) {
                for (int i : enabledFields) {
                    filterOptions.get(i).setChecked(true);
                }
            }
        }

        return view;
    }

    @Override
    public void onPause() {
        super.onPause();

        enabledFields.clear();
        for (int i = 0; i < filterOptions.size(); i++) {
            if (filterOptions.get(i).isChecked()) {
                enabledFields.add(i);
            }
        }
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        outState.putIntegerArrayList(INPUT_EXTRA, enabledFields);
    }
}
