RecyclerView中的ViewPager确实从第二行显示

Question

我想在我的RecyclerView行中添加带有tablayout的ViewPager。但我在ViewPager中添加的片段只显示在第二行，从第二行开始，只是TabLayout显示，ViewPager中的片段未显示。我阅读并发现每个ViewPager都需要设置ID。 ViewPager不允许在同一个片段中共享id，即使它是recyclerview上下文的一部分。但我不知道该怎么做。任何人都可以告诉我我需要做什么步骤或其他方法？非常感谢你。 编码我的RecyclerView适配器 公共类ListArtifactsAdapter extends

我的ViewPager适配器

public class ArtifactInformationAdapter extends FragmentStatePagerAdapter {

    private  List<Fragment> mFragmentList = new ArrayList<>();
    private  List<String> mFragmentTitleList = new ArrayList<>();

    public ArtifactInformationAdapter(FragmentManager fragmentManager,String audio, String transcript) {
        super(fragmentManager);

        mFragmentList.add(AudioFragment.newInstance(audio));
        mFragmentList.add(TranscriptFragment.newInstance(transcript));
        mFragmentTitleList.add("Audio");
        mFragmentTitleList.add("Transcript");
    }


    @Override
    public int getCount() {
        return mFragmentList.size();
    }

    @Override
    public int getItemPosition(Object object) {
        return POSITION_NONE;
    }

    @Override
    public Fragment getItem(int position) {
           return mFragmentList.get(position);
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return mFragmentTitleList.get(position);
    }
}
