关于listview上下滑动imageview图片混乱问题

问题代码：

@Override
public View getView(int position, View view, ViewGroup parent)
{final ViewHolder mViewHolder;if(null == view){mViewHolder = new ViewHolder();view = LayoutInflater.from(mContext).inflate(R.layout.fragment_deal_order_list_item, null);mViewHolder.txtOrderDealstatus = (ImageView) view.findViewById(R.id.order_deal_status);mViewHolder.txtOrderNumber = (TextView) view.findViewById(R.id.dealorder_number);mViewHolder.txtOrderNum = (TextView) view.findViewById(R.id.deal_order_num);mViewHolder.txtDealOrderTime = (TextView) view.findViewById(R.id.dealorder_time);mViewHolder.txtCustomerName = (TextView) view.findViewById(R.id.customer_name);mViewHolder.txtCustomerAddress = (TextView) view.findViewById(R.id.customer_address);mViewHolder.txtOrderSendTime = (TextView) view.findViewById(R.id.customer_post_time);mViewHolder.txtOrderGoodsDes = (TextView) view.findViewById(R.id.customer_list_goods_des);mViewHolder.txtCustomerPhone = (TextView) view.findViewById(R.id.customer_phone);mViewHolder.txtPostManName = (TextView) view.findViewById(R.id.postman_name);mViewHolder.txtPostManPhone = (TextView) view.findViewById(R.id.postman_phone);mViewHolder.listgoods = (ListView) view.findViewById(R.id.customer_list_goods);mViewHolder.linerDealOrderTitle = (LinearLayout) view.findViewById(R.id.deal_order_item_title);mViewHolder.linearDeralOrderCotent = (LinearLayout) view.findViewById(R.id.show_order_message);mViewHolder.linearPosterCotentTitle = (LinearLayout) view.findViewById(R.id.poster_message_title);mViewHolder.linearPosterCotent = (LinearLayout) view.findViewById(R.id.poster_message);view.setTag(mViewHolder);}else
    {mViewHolder = (ViewHolder) view.getTag();}if(listOrder.get(position).getPostmanid() == null || listOrder.get(position).getPostmanid() == 0){mViewHolder.linearPosterCotentTitle.setVisibility(View.GONE);mViewHolder.linearPosterCotent.setVisibility(View.GONE);}Log.i("DealOrderAdapter","position:" + position);if(listOrder.get(position).getOrderSeller().getSellerordersequence() == null){mViewHolder.txtOrderNum.setText("#");}else
    {int sequence = listOrder.get(position).getOrderSeller().getSellerordersequence();mViewHolder.txtOrderNum.setText("#" + String.format("%02d",sequence));}mViewHolder.txtOrderNumber.setText(String.valueOf(listOrder.get(position).getOrderSeller().getSellerordernum()));mViewHolder.txtDealOrderTime.setText(listOrder.get(position).getOrdertime());mViewHolder.txtPostManName.setText(listOrder.get(position).getPostmanname());mViewHolder.txtPostManPhone.setText(listOrder.get(position).getPostmanphonenum());mViewHolder.txtCustomerName.setText(listOrder.get(position).getAcceptname());mViewHolder.txtCustomerAddress.setText(listOrder.get(position).getAcceptlocation());mViewHolder.txtOrderSendTime.setText(listOrder.get(position).getGoodsarrivetime());mViewHolder.txtOrderGoodsDes.setText(listOrder.get(position).getOrderSeller().getRemark());mViewHolder.txtCustomerPhone.setText(listOrder.get(position).getAcceptphonenum());Log.i("lxl","getSellerorderstatus:" + listOrder.get(position).getOrderSeller().getSellerorderstatus()+ ";position:" + position);if(listOrder.get(position).getOrderSeller().getSellerorderstatus() == 2) {mViewHolder.txtOrderDealstatus.setImageResource(R.drawable.jujue);}OrderGoodsListItemAdapter mOrderGoodsListItemAdapter = new OrderGoodsListItemAdapter(mContext,listOrder.get(position).getOrderSeller().getLstOrderGoods());mViewHolder.listgoods.setAdapter(mOrderGoodsListItemAdapter);setListViewHeightOnChildren( mViewHolder.listgoods);return view;
}public class ViewHolder{ImageView txtOrderDealstatus;TextView txtOrderNum;TextView txtOrderNumber;TextView txtDealOrderTime;TextView txtCustomerName;TextView txtCustomerPhone;TextView txtCustomerAddress;//送单时间
    TextView txtOrderSendTime;TextView txtOrderGoodsDes;TextView txtPostManName, txtPostManPhone;ListView listgoods;LinearLayout linerDealOrderTitle;LinearLayout linearDeralOrderCotent;LinearLayout linearPosterCotentTitle;LinearLayout linearPosterCotent;
}

上下滑动的时候，图片都变成了 R.drawable.jujue  默认图片是 R.drawable.queren

修改：只是将if 后面加上else分之  这个bug就避免了

if(listOrder.get(position).getOrderSeller().getSellerorderstatus() == 2) {mViewHolder.txtOrderDealstatus.setImageResource(R.drawable.jujue);
}
else
{mViewHolder.txtOrderDealstatus.setImageResource(R.drawable.queren);
}

这个问题确实很奇怪！！！ 只能说在listview的适配器 getview中 多处使用if分支，会对数据加载有影响，最好保证if else逻辑的完整性。
