滚动时回收视图重叠项目

Question

大家好我正面临着回收视图的问题。 我使用带滑动的循环视图来更改项目位置功能，用户可以通过长按项目来更改项目的位置。

所有项目都具有不同类型的视图。

一切正常，但是当我试图滚动视图时，循环视图中显示的项目相互重叠。

我在google上搜索并获得了覆盖该方法的解决方案。

 @Override
   public int getItemViewType(int position) {
       return position;
   }

当我在我的适配器类中使用此方法时，我的滑动以更改视图功能停止工作。

任何人都可以解释我为什么会发生这种情况......？

这是整个适配器类

public class CreateEmailAdapter extends RecyclerView.Adapter<CreateEmailAdapter.MyViewHolder> implements ItemTouchHelperAdapter {

    private static final String TAG = "CreateEmailAdapter";

    public int position = 0;

    public ArrayList<CampaignData> List;

    private final OnStartDragListener mDragStartListener;

    public CreateEmailAdapter(ArrayList<CampaignData> List, OnStartDragListener mDragStartListener) {
        this.List = List;
        this.mDragStartListener = mDragStartListener;
    }

    public class MyViewHolder extends RecyclerView.ViewHolder {

        public TextView title;
        public ImageView imageView, imageView2, imageView3;
        RelativeLayout MainListView;


        public MyViewHolder(final View view) {
            super(view);

            parentLayout = (RelativeLayout) view.findViewById(R.id.parentLayout);

            MainListView = (RelativeLayout) view.findViewById(R.id.MainListView);

            title = (TextView) view.findViewById(R.id.MainTitle);

            imageView2 = (ImageView) view.findViewById(R.id.imageViewPopup);

            imageView3 = (ImageView) view.findViewById(R.id.movearrows);

            imageView = (ImageView) view.findViewById(R.id.lytPatternColorDraw);

            parentLayout.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view1) {

                    position = getAdapterPosition();

                    HandleResponse(title.getText().toString(), view1, getAdapterPosition());
                }
            });
        }
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View mView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_row, parent, false);
        return new MyViewHolder(mView);
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, int position) {

        CampaignData campaignData = this.List.get(position);

        holder.parentLayout.setTag(campaignData);

        String extraData = campaignData.getExtraData();

        String MediaType = campaignData.getMediaType();

        holder.MainListView.setVisibility(View.VISIBLE);

        holder.title.setText(campaignData.getTitle());

        holder.imageView.setImageResource(campaignData.getimage());

        holder.imageView2.setTag(campaignData); 

        holder.imageView3.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (MotionEventCompat.getActionMasked(event) == MotionEvent.ACTION_DOWN) {
                    mDragStartListener.onStartDrag(holder);
                }
                return false;
            }
        });
    }

    @Override
    public boolean onItemMove(int fromPosition, int toPosition) {
        Collections.swap(List, fromPosition, toPosition);
        notifyItemMoved(fromPosition, toPosition);
        return true;
    }

    @Override
    public void onItemDismiss(int position) {
        List.remove(position);
        notifyItemRemoved(position);
    }

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

//    @Override
//    public int getItemViewType(int position) {
//        return position;
//    }

    public int getPosition() {
        return position;
    }
