ListView使用XUtils图片闪烁

Question

ListView的每个item上都可能有时间不同的Timer定时器，每个item上可能显示图片（有活动显示图片）。
我填充了两种不同的item布局，一种带背景图片的，一种不带。如果任意item有倒计时，则Timer每秒调用一次adapter.notifyDataSetChanged。

现在的问题是图片偶尔、是偶尔可能会闪烁（个人猜测和Timer相关）。
product_newYear_img（宽度match_parent,高40dp）,设置tag，但好像扔无济于事。求大神解决。
adapter相关代码如下。

@Override
public View getView(int position, View convertView, ViewGroup parent) {

// Log.i("TAG", "getView"+position);
if (convertView == null) {
Log.i("TAG", "convertView == null"+position);
holder = new ViewHolder();
if (getItemViewType(position) == 0) {// 有活动
convertView = mInflater.inflate(R.layout.homepage_product_list_item_activity, null);
holder.product_newYear_img = (ImageView) convertView.findViewById(R.id.product_newYear_img);
} else {
convertView = mInflater.inflate(R.layout.homepage_product_list_item, null);
}

        holder.product_title = (TextView) convertView.findViewById(R.id.product_title);
        holder.product_time = (TextView) convertView.findViewById(R.id.product_time);
        holder.product_apr_title = (TextView) convertView.findViewById(R.id.product_apr_title);
        holder.product_apr = (TextView) convertView.findViewById(R.id.product_apr);
        holder.product_time_limit = (TextView) convertView.findViewById(R.id.product_time_limit);
        holder.product_lowest = (TextView) convertView.findViewById(R.id.product_lowest);
        holder.product_progress = (RoundProgressBar) convertView.findViewById(R.id.product_progress);
        holder.product_status = (TextView) convertView.findViewById(R.id.product_status);
        holder.product_title_bt = (TextView) convertView.findViewById(R.id.product_title_bt);

        holder.product_relayout = (RelativeLayout) convertView.findViewById(R.id.product_relayout);
        holder.product_blankSpace = convertView.findViewById(R.id.product_blankSpace);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    if (getItemViewType(position) == 0) {//有活动

        if (!getItem(position).getActivitylist().equals(holder.product_relayout.getTag())) {
            mBitmapUtils.display(holder.product_relayout, getItem(position).getActivitylist());
            holder.product_relayout.setTag(getItem(position).getActivitylist());
        }
        if (!getItem(position).getActivitylist().equals(holder.product_newYear_img.getTag())) {
            mBitmapUtils.display(holder.product_newYear_img, getItem(position).getActivitybg());
            holder.product_newYear_img.setTag(getItem(position).getActivitybg());
        }

// mBitmapUtils.display(holder.product_relayout, getItem(position).getActivitylist());
// mBitmapUtils.display(holder.product_newYear_img, getItem(position).getActivitybg());
}else{
holder.product_relayout.setBackgroundDrawable(context.getResources().getDrawable(R.drawable.item_selector));
}

    // 有补贴
    if (TextUtils.isEmpty(getItem(position).getApr_add())||getItem(position).getApr_add().equals(Constant.NUMBER_0)||Double.valueOf(getItem(position).getApr_add())==0) {
        holder.product_apr.setText(context.getString(R.string.product_apr_t,getItem(position).getApr()));
        holder.product_title_bt.setVisibility(View.GONE);
    }else{
        holder.product_apr.setText(context.getString(R.string.product_apr_total,getItem(position).getApr(),getItem(position).getApr_add()));
        holder.product_title_bt.setVisibility(View.VISIBLE);
    }

    holder.product_title.setText(getItem(position).getName());

    if (!TextUtils.isEmpty(getItem(position).getSurplus_time())) {
        Log.i("TAG", "getItem(position).getSurplus_time()="+getItem(position).getSurplus_time());
        holder.product_time.setText(getItem(position).getSurplus_time());
    }

    holder.product_apr_title.setText(context.getString(R.string.product_apr_title));
    holder.product_time_limit.setText(context.getString(R.string.product_time_limit, getItem(position).getTime_limit()));
    holder.product_lowest.setText(context.getString(R.string.product_lowest, DisplayFormat.intFormat(getItem(position).getLowest_account())));
    holder.product_status.setText(Utils.getProductStatus(type, getItem(position).getStatus(), getItem(position).getScales()));

    if (holder.product_status.getText().equals(Constant.PRODUCT_STATUS_HKZ1) ||
        holder.product_status.getText().equals(Constant.PRODUCT_STATUS_HKZ2)) {
        holder.product_progress.setCricleProgressColor(Color.LTGRAY);
    } else {
        holder.product_progress.setCricleProgressColor(context.getResources().getColor(R.color.rpb_roundProgressColor));
    }

    holder.product_progress.setProgress(Float.valueOf(getItem(position).getScales()));
    return convertView;
}

Answer 1

自己解决了（ !getItem(position).getActivitylist().equals(holder.product_newYear_img.getTag())
这里写错了应该是（ !getItem(position).getActivitybg().equals(holder.product_newYear_img.getTag())
大家不要像我一样犯这种低级错误~
