GridViewAdapter中的异常

Question

在gridview适配器中，我有以下代码：

public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        ViewHolder view;
        LayoutInflater inflator = activity.getLayoutInflater();

        if(convertView==null)
        {
            view = new ViewHolder();
            convertView = inflator.inflate(R.layout.gridview_row, null);

            view.txtViewTitle = (TextView) convertView.findViewById(R.id.date);
            view.imgViewFlag = (ImageView) convertView.findViewById(R.id.imageView1);

            convertView.setTag(view);
        }
        else
        {
            view = (ViewHolder) convertView.getTag();
        }

        view.txtViewTitle.setText(listCountry.get(position));
        view.imgViewFlag.setImageResource(listFlag.get(position));

        return convertView;
    }

根据我的逻辑，代码应该没问题。但我的logcat中有一个例外。错误描述如下：

在第72行中，该行为：view.imgViewFlag.setImageResource(listFlag.get(position));如何解决此异常？

确保你的listFlag不为空并检查你的布局gridview_row是imageview的id是一样的..
