Answer 1

您可以利用各种方法，例如diff()，asYears()

＆＃13;

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

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        Injector.component().inject(this);

        setupViewPager(viewPager);
        tabLayout.setupWithViewPager(viewPager);
    }

    @Override
    public void onResume() {
        super.onResume();
    }

    private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getFragmentManager());
        adapter.addFragment(new RouteFragment(), "Map");
        adapter.addFragment(new RouteListFragment(), "List");
        viewPager.setAdapter(adapter);
    }

＆＃13;

var firstDate = moment("2013-12-01", 'YYYY-MM-DD'); //Create date using string-format constructor
var secondDate = moment("2016-12-01", 'YYYY-MM-DD');
var duration = moment.duration(secondDate.diff(firstDate));
var years = duration.asYears();
console.log(years)
console.log(Math.round(years))

＆＃13;

Answer 2

var a = moment([2015, 11, 29]);
var b = moment([2007, 06, 27]);

var years = a.diff(b, 'year');

console.log(years + ' years);
