Eu tenho uma situação estranha, eu tenho umaActivity hospedando umTabLayout/Viewpager que preenche dados com base em alterações em um banco de dados Firebase. Infelizmente, oRecyclerView não está sendo preenchido e estou recebendo o erro abaixo no meu logcat. Acredito que o fragmento esteja sendo carregado mesmo quando não estiver na tela, o que está causando um erro na população doRecyclerView. Também é estranho como oRecyclerView é preenchido quando eu giro a tela:

12-13 21:31:40.013 12490-12490/com.troychuinard.fanpolls E/RecyclerView: No adapter attached; skipping layout

Aqui está oViewPager Adaptador que tenho no meu hostActivity:

public class SectionPagerAdapter extends FragmentPagerAdapter {

    public SectionPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        switch (position) {
            case 0:
                return new TrendingFragment();
            case 1:
                return new FollowingFragment();
            case 2:
                return new LiveFragment();
            default:
                return new TrendingFragment();
        }
    }

    @Override
    public int getCount() {
        return 3;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        switch (position) {
            case 0:
                return getResources().getString(R.string.trending_text);
            case 1:
                return getResources().getString(R.string.following_text);
            case 2:
                return getResources().getString(R.string.new_text);
            default:
                return getResources().getString(R.string.trending_text);
        }
    }
}

Aqui está o fragmento completo onde eu inicializo oRecyclerView dentroonCreateView() função na minhaLiveFragment, que é a guia 3 noTabLayout:
