MvvmCross ViewPager not show in Activity

I want to show a few tabs sharing the same viewmodel with viewpager in an activity. I am using MvvmCross 5.6.2.

When I do that in a fragment, the viewpager is shown properly. Using the same method, I add tab fragments to the viewpager in an activity with code like this:

        var viewPagerFragmentList = new List<MvxViewPagerFragmentInfo>
                {
                    new MvxViewPagerFragmentInfo("Personal", typeof (SettingPersonalFragment), ViewModel),
                    new MvxViewPagerFragmentInfo("Preference", typeof (SettingPreferenceFragment), ViewModel)
                };
        viewPager.Adapter = new MvxCachingFragmentStatePagerAdapter(this, SupportFragmentManager, viewPagerFragmentList);

        var tabLayout = FindViewById<TabLayout>(Resource.Id.tabs_fragment_setting_viewpager);
        tabLayout.SetupWithViewPager(viewPager);

The tab fragments are not shown on screen, though the tab fragment's OnCreate and OnCreateView are executed.

I found the latest sample Playground is showing tabs in activity too. Following the sample, I register the fragment:

    [MvxTabLayoutPresentation(TabLayoutResourceId = Resource.Id.tabs_fragment_setting_viewpager, ViewPagerResourceId = Resource.Id.viewpager_fragment_setting_viewpager, Title = "Personal", ActivityHostViewModelType = typeof(SettingViewModel))]

No luck with that. The last thing I found in Playground to show a tab is to navigate to the fragment viewmodel:

    _navigationService.Navigate<Tab2ViewModel>();
    _navigationService.Navigate<Tab3ViewModel>();

However, in my case, I do not have a viewmodel for each fragment. The workaround on my hand is to move the viewpager to a fragment in the activity.

How could I show the viewpager fragments without their own viewmodels in an activity?

Thanks,

Nick

The above code that works in fragment also work in activity. There is an issue in the xml causing the viewpager not showing. Sorry.

Thanks everyone who helped.
