单击选项卡项来自下一个选项卡项的响应

Question

我有一个片段与片段寻呼机适配器实现表布局每个选项卡有一个回收器视图与一些项目（相同的回收器视图适配器为所有recylerview）通过实现OnItemClick侦听器点击每个项目调用一个活动，实现了一个视图寻呼机与片段StatePagerAdapter，以显示回收器视图项目基于滑动的表布局视图寻呼机显示上一个或下一个选项卡项目每个项目的数据存储在一个数组列表中。

 viewPager = (ViewPager) view.findViewById(R.id.viewpager);
    //setupViewPager(viewPager);
    MyFragmentPagerAdapter adapter = new MyFragmentPagerAdapter(getChildFragmentManager(),getActivity());

    adapter.addFrag(new OneFragment(), "title1");
    adapter.addFrag(new TwoFragment(), "title2");
    adapter.addFrag(new ThreeFragment(), "title3");
    viewPager.setAdapter(adapter);
    tabLayout = (TabLayout) view.findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(viewPager);

一个片段和两个片段和…是相似的：

rv=(RecyclerView) view.findViewById(R.id.rv);

        StaggeredGridLayoutManager sglm = new StaggeredGridLayoutManager(2,StaggeredGridLayoutManager.VERTICAL);
        rv.setLayoutManager(sglm);
        rv.setHasFixedSize(true);
persons = new ArrayList<>();



          persons.add(new Person("name", "age","email","phone","resume", R.drawable.photo));
     persons.add(new Person("name", "age","email","phone","resume", R.drawable.photo));
    .
    .
    .      

 for (int j=0; j < persons.size() ;j++){
            PersonItem personItem = new PersonItem();
            personItem.setName(persons.get(j).name);
            personItem.setAge(persons.get(j).age);
            personItem.setEmail(persons.get(j).email);
            personItem.setPhone(persons.get(j).phone);
            personItem.setResume(persons.get(j).resume);
            personItem.setImageId(persons.get(j).photoId);
            personList1.addItem(personItem);

 RVAdapter adapter = new RVAdapter(getContext(),persons);


        adapter.setOnItemClickListener(new RVAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(View view, int position) {
                int pos = position;



                Bundle bundle = new Bundle();
                bundle.putSerializable("person", personList1);
                Intent intent = new Intent(getContext(),
                        MyActivity.class);
                intent.putExtras(bundle);
                intent.putExtra("pos", pos);

                startActivity(intent);

            }

        });
        rv.setAdapter(adapter);

回收器视图适配器:

public class RVAdapter extends RecyclerView.Adapter<RVAdapter.PersonViewHolder> {
    private Context mContext;
    private static OnItemClickListener listener;

   //AdapterView.OnItemClickListener listener;
    // Define the listener interface
    public interface OnItemClickListener {
        void onItemClick(View itemView, int position);
    }
    // Define the method that allows the parent activity or fragment to define the listener
    public void setOnItemClickListener(OnItemClickListener listener) {
        this.listener = listener;
    }


    public static class PersonViewHolder extends RecyclerView.ViewHolder {

        CardView cv;
        TextView personName;
        TextView personAge;
        ImageView personPhoto;

        PersonViewHolder(final View itemView) {
            super(itemView);
            cv = (CardView)itemView.findViewById(R.id.cv);
            personName = (TextView)itemView.findViewById(R.id.person_name);
            personAge = (TextView)itemView.findViewById(R.id.person_age);
            personPhoto = (ImageView)itemView.findViewById(R.id.person_photo);

            // Setup the click listener
            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // Triggers click upwards to the adapter on click
                    if (listener != null)
                        listener.onItemClick(itemView, getLayoutPosition());
                }
            });
        }
    }

    List<Person> persons;

    public RVAdapter(Context context , List<Person> persons){
        this.persons = persons;
        mContext = context;
    }

    @Override
    public void onAttachedToRecyclerView(RecyclerView recyclerView) {
        super.onAttachedToRecyclerView(recyclerView);
    }

    @Override
    public PersonViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item, viewGroup, false);
        PersonViewHolder pvh = new PersonViewHolder(v);
        return pvh;
    }

    @Override
    public void onBindViewHolder(PersonViewHolder personViewHolder, int i) {
        personViewHolder.personName.setText(persons.get(i).name);
        personViewHolder.personAge.setText(persons.get(i).age);
        personViewHolder.personPhoto.setImageResource(persons.get(i).photoId);
    }

    @Override
    public int getItemCount() {
        return persons.size();
    }
}

为了解决这个问题，我将RvAdapter类作为每个选项卡片段中的内部和私有类：

 private static class RVAdapter extends RecyclerView.Adapter<RVAdapter.PersonViewHolder> {

 //...and keep remaning
