使用滑动触摸监听器在RecyclerView中撤消

Question

我在RecyclerView中得到了一些简单的物品清单。使用SwipeTouchHelper，它可以很好地用于撤消和删除操作。我面临的问题是，当我按下Snakbar中的undo时，它会还原项目，并且在下一行中还会显示滑动条。

 @Override
public void onSwiped(final RecyclerView.ViewHolder viewHolder, int direction, int position) {

    ListNoteDataBase appDatabase = new ListNoteDataBase(context);
    appDatabase.open();
    itemsList = appDatabase.getfullList(title_id);
    appDatabase.close();

    // get the removed item name to display it in snackbar

    String text = itemsList.get(viewHolder.getAdapterPosition()).getText();
    final String id = itemsList.get(position).getId();


    // backup of removed item for undo purpose
    final int adapterPosition = viewHolder.getAdapterPosition();
    final ItemModel items = itemsList.get(adapterPosition);

    // showing snack bar with Undo option

    Snackbar snackbar = Snackbar.make(coordinatorLayout, text + " removed !", Snackbar.LENGTH_SHORT);
   snackbar.setAction("UNDO", new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    adapter.restoreItem(items, adapterPosition);
   }});
    snackbar.addCallback(new BaseTransientBottomBar.BaseCallback<Snackbar>() {

        public void onDismissed(Snackbar transientBottomBar, int event) {
            switch (event) {
                case DISMISS_EVENT_TIMEOUT:
                    ListNoteDataBase appDatabase = new ListNoteDataBase(context);
                    adapter.removeItem(viewHolder.getAdapterPosition());
                    appDatabase.open();
                    appDatabase.deleteNotes(id);
                    adapter = new NoteListAdapter(context, appDatabase.getfullList(title_id));
                    recyclerView.setAdapter(adapter);
                    adapter.registerAdapterDataObserver(new RecyclerView.AdapterDataObserver() {
                        @Override
                        public void onChanged() {
                            super.onChanged();
                            checkEmpty();
                        }

                        @Override
                        public void onItemRangeInserted(int positionStart, int itemCount) {
                            super.onItemRangeInserted(positionStart, itemCount);
                            checkEmpty();
                        }

                        @Override
                        public void onItemRangeRemoved(int positionStart, int itemCount) {
                            super.onItemRangeRemoved(positionStart, itemCount);
                            checkEmpty();
                        }});
                    adapter.notifyDataSetChanged();
                    appDatabase.close();
                    break;
            }
        }
    });

    snackbar.setActionTextColor(Color.RED);
    snackbar.show();
}

从适配器恢复项目的代码：

 public void restoreItem(ItemModel item, int position) {
    data.add(position, item);
    notifyItemInserted(position);
}

In the image, the red line show below a text appears after I press the Undo button from the snakbar

请指导我如何解决此问题。
