Problem with deleting item

Log.d("DetailAdapter", "Delete item with ID: " + String.valueOf(getId));
                            try {
                                databaseHelper.deleteItemById(getId);
                                removeItem(holder.getBindingAdapterPosition());
                            }
                            catch(Exception error) {
                                Log.d("DetailAdapter", "Error with delete item(error)");
                                error.printStackTrace();
                            }

DatabaseHelper

public void deleteItemsByCategory(String categoryName) {
        SQLiteDatabase db = this.getWritableDatabase();
        db.delete(TABLE_NAME, COLUMN_CATEGORY + " = ?", new String[]{categoryName});
        db.close();
    }

public void deleteItemById(Integer id) {
        SQLiteDatabase db = this.getWritableDatabase();
        int deletedRows = db.delete(TABLE_NAME, COLUMN_ID + " = ?", new String[]{String.valueOf(id)});
        db.close();
        if (deletedRows > 0) {
            Log.d("DatabaseHelper", "Item with ID " + String.valueOf(id) + " was deleted.");
        } else {
            Log.d("DatabaseHelper", "No item with ID " + String.valueOf(id) + " was found.");
        }
    }

In debug get right ID number

Integer getId = loginDataArrayList.get(holder.getBindingAdapterPosition()).getId();

But after call databaseHelper.deleteItemById get this error.
In database have items, with right IDs, have normal list from DB.

I dont understand what cant see. Please help.
