Android Udacity：ResourceException 0xfffffffff

Question

This is the link to my app我是udacity website中的一个项目。

我使用的是回收者视图而不是列表视图...而且其他一切都是相同的 当我从工具栏中单击 up 按钮时，会出现错误 它给出了一个

  

资源未找到异常

但按下物理后退按钮时其他一切似乎都没问题。
我似乎无法弄清楚错误的原因是什么，找不到哪个资源以及为什么它只出现在单击 up 按钮而不是 back 按钮......？

My CursorRecyclerViewAdapter 

    Context mContext;
    public final static int View_Type_Today = 0 ;
    public final static int View_Type_Future = 1 ;

    public MyListCursorAdapter(Context context,Cursor cursor){
        super(context,cursor);
        mContext = context;
    }



    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        else{

        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(layoutID, parent, false);
        ViewHolder vh = new ViewHolder(itemView);
        return vh;

Viewholder类

  TextView tvDate;
  TextView high;
  TextView low;
  TextView desc;
        View container;
        ImageView iv;
        public ViewHolder(View itemView) {
            super(itemView);
            desc= (TextView)itemView.findViewById(R.id.list_item_forecast_textview);
            high= (TextView)itemView.findViewById(R.id.list_item_high_textview);
            low= [enter image description here][1](TextView)itemView.findViewById(R.id.list_item_low_textview);
            tvDate= (TextView)itemView.findViewById(R.id.list_item_date_textview);
            iv = (ImageView) itemView.findViewById(R.id.list_item_icon);
            container = itemView;
        }
