如何在Vertical RecyclerView中处理Horizo​​ntal RecyclerView

Question

I am using a RecyclerView and inside this I added a Horizontal RecyclerView for showing images like a gallery.

I am inserting my RecyclerView rows one by one after user enter his details.

My main problem is I am selecting images through Camera or Gallery, and they are displaying well in horizontal RecyclerView.

However, when a user adds one more cell, then some previous images are coming in that cell. This is incorrect.

How can I resolve this problem?

My main Activity:-

 private void addDoctorDetails() {

        try {
            personalInformatioDoctorCatogoryBeanArrayList.add(new PersonalInformatioDoctorCatogoryBean("Physician" + i, "MBBS" + i, "1985" + i,imagesBeanArrayList));
            personalInformationRecyclerDoctorCatogoryAdapter.notifyDataSetChanged();
            i++;
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
    } 

PersonalInformationRecyclerDoctorCatogoryAdapter:-

private List<PersonalInformatioDoctorCatogoryBean> personalInformatioDoctorCatogoryBeanList;
    private Context context;

    public PersonalInformationRecyclerDoctorCatogoryAdapter(Context context, List<PersonalInformatioDoctorCatogoryBean> personalInformatioDoctorCatogoryBeanList) {
        this.context = context;
        this.personalInformatioDoctorCatogoryBeanList = personalInformatioDoctorCatogoryBeanList;
    }

    @Override
    public VHItem onCreateViewHolder(ViewGroup parent, int viewType) {
        try {
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.adapter_personal_information_step2_list_items, parent, false);
            return new VHItem(v);
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
        return null;
    }

    @Override
    public void onBindViewHolder(VHItem viewHolder, final int position) {

        try {

            viewHolder.speciality.setText(personalInformatioDoctorCatogoryBeanList.get(position).getSpeciality());
            viewHolder.qualification.setText(personalInformatioDoctorCatogoryBeanList.get(position).getQualification() + "(" + personalInformatioDoctorCatogoryBeanList.get(position).getYear() + ")");

            //Getting imagesBeanArrayList position images
            ArrayList<ImagesBean> imagesBeanArrayList = personalInformatioDoctorCatogoryBeanList.get(position).getImagesBeanList();

            //Set Horizental recyclerView  adapter
            HorizontalListAdapter horizontalListAdapter = new HorizontalListAdapter(context, imagesBeanArrayList);
            viewHolder.horizentalView.setHasFixedSize(true);
            viewHolder.horizentalView.setLayoutManager(new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false));
            viewHolder.horizentalView.setAdapter(horizontalListAdapter);
            viewHolder.horizentalView.setNestedScrollingEnabled(false);

        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
    }

    @Override
    public int getItemCount() {

        return personalInformatioDoctorCatogoryBeanList.size();
    }

    class VHItem extends RecyclerView.ViewHolder {

        private TextView speciality, qualification;
        private RecyclerView horizentalView;

        public VHItem(View view) {

            super(view);

            speciality = (TextView) view.findViewById(R.id.speciality_textview);
            qualification = (TextView) view.findViewById(R.id.qualification_textview);
            horizentalView = (RecyclerView) view.findViewById(R.id.horizontal_recycler);
        }
    }

PersonalInformatioDoctorCatogoryBean:-

 private String speciality;
    private String qualification;
    private String year;
    private ArrayList<ImagesBean> imagesBeanList;

    public PersonalInformatioDoctorCatogoryBean(String speciality, String qualification, String year,ArrayList<ImagesBean> imagesBeanList) {
        this.speciality = speciality;
        this.qualification = qualification;
        this.year = year;
        this.imagesBeanList = imagesBeanList;
    }

    public String getSpeciality() {
        return speciality;
    }

    public void setSpeciality(String speciality) {
        this.speciality = speciality;
    }

    public String getQualification() {
        return qualification;
    }

    public void setQualification(String qualification) {
        this.qualification = qualification;
    }

    public String getYear() {
        return year;
    }

    public void setYear(String year) {
        this.year = year;
    }

    public ArrayList<ImagesBean> getImagesBeanList() {
        return imagesBeanList;
    }

    public void setImagesBeanList(ArrayList<ImagesBean> imagesBeanList) {
        this.imagesBeanList = imagesBeanList;
    }

In my observation, you are passing same reference of imagesBeanArrayList in each record insert. Try to pass fresh array when you add new one.

private void addDoctorDetails() {
    try {
        personalInformatioDoctorCatogoryBeanArrayList.add(
                new PersonalInformatioDoctorCatogoryBean(
                         "Physician" + i, "MBBS" + i, "1985" + i, 
                         new ArrayList<ImagesBean>()));

        personalInformationRecyclerDoctorCatogoryAdapter.notifyDataSetChanged();
        i++;
    } catch (Throwable throwable) {
        throwable.printStackTrace();
    }
}
