android ListView在更新项闪烁时带有持有者模式

我用基本适配器创建了一个listView，它实现了ViewHolder模式。 listview中的每个项目都有一个倒计时。工作正常，但是如果我想更新listview 倒计时在新值和旧值之间闪烁

如何解决这个问题

BaseAdapter getView（）

每个项目的倒计时

@Override
public void run() {
    int j = 0;
    for (int nTime : listOfTimes) {
        listOfTimes.set(j, nTime - 1);
        j++;
    }

    if (lv.getCount() <= 0) {
        return;
    }
    int nAmountVisible = lv.getLastVisiblePosition() - lv.getFirstVisiblePosition();
    for (int i = 0; i <= nAmountVisible; i++) {
        long lTimeFromList = listOfTimes.get(lv.getFirstVisiblePosition() + i);

        // transform timestamp to readable date
        long weeks = TimeUnit.SECONDS.toDays(lTimeFromList) / 7;
        long days = TimeUnit.SECONDS.toDays(lTimeFromList) - (7 * weeks);
        long hours = TimeUnit.SECONDS.toHours(lTimeFromList) - TimeUnit.DAYS.toHours(days) - TimeUnit.DAYS.toHours(7 * weeks);
        long minute = TimeUnit.SECONDS.toMinutes(lTimeFromList) - (TimeUnit.SECONDS.toHours(lTimeFromList) * 60);
        long second = TimeUnit.SECONDS.toSeconds(lTimeFromList) - (TimeUnit.SECONDS.toMinutes(lTimeFromList) * 60);

        View viewHolder = lv.getChildAt(i);
        AuctionAdapter.ViewHolder localHolder = (AuctionAdapter.ViewHolder) viewHolder.getTag();
        viewHolder.invalidate();

        localHolder.startingAt.setText(weeks + "w " + days + "d " + hours + "h " + minute + "m " + second + "s ");

    }
    mHandler.postDelayed(this, 1000);
}

正确使用支架的方法应如下所示：

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    ViewHolder holder = null;
    if (convertView == null)
    {
        LayoutInflater inflater = LayoutInflater.from(context);
        convertView = inflater.inflate(R.layout.row_item, null);
        holder = new ViewHolder();

        holder.name = (TextView) convertView.findViewById(R.id.name);
        holder.startingAt = (TextView) convertView.findViewById(R.id.starting_at);

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

    Model current = list.get(position);
    holder.name.setText(current.name);

    return convertView;
}

编辑：

您不应该从正在运行的线程设置

TextView

值，而应该直接从

getView

方法设置

在

返回视图之前添加此行：

holder.startingAt.setText(current.timer);

在您的
模型
类中，添加一个新字段：

public String timer = null;

然后在运行线程中（倒计时）：

对于（int i=0；我感谢但没有解决我的问题…我在我的问题中进行了更新为什么要使用
onCreateView
重用视图？Listview机制已经完成了这项工作。我认为这是一个更好的方法。要重用视图，您可以重复使用多少。我将尝试不使用。我完成了修改，问题仍然存在。我已经更新了我的an回答。问题似乎出在您的
run
方法中。
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    ViewHolder holder = null;
    if (convertView == null)
    {
        LayoutInflater inflater = LayoutInflater.from(context);
        convertView = inflater.inflate(R.layout.row_item, null);
        holder = new ViewHolder();

        holder.name = (TextView) convertView.findViewById(R.id.name);
        holder.startingAt = (TextView) convertView.findViewById(R.id.starting_at);

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

    Model current = list.get(position);
    holder.name.setText(current.name);

    return convertView;
}

holder.startingAt.setText(current.timer);

public String timer = null;

@Override
public void run()
{
    for (int i = 0; i <= listOfTimes.size(); i++)
    {
        long lTimeFromList = listOfTimes.get(i);

        // transform timestamp to readable date
        long weeks = TimeUnit.SECONDS.toDays(lTimeFromList) / 7;
        long days = TimeUnit.SECONDS.toDays(lTimeFromList) - (7 * weeks);
        long hours = TimeUnit.SECONDS.toHours(lTimeFromList) - TimeUnit.DAYS.toHours(days) - TimeUnit.DAYS.toHours(7 * weeks);
        long minute = TimeUnit.SECONDS.toMinutes(lTimeFromList) - (TimeUnit.SECONDS.toHours(lTimeFromList) * 60);
        long second = TimeUnit.SECONDS.toSeconds(lTimeFromList) - (TimeUnit.SECONDS.toMinutes(lTimeFromList) * 60);

        listOfTimes.get(i).timer = weeks + "w " + days + "d " + hours + "h " + minute + "m " + second + "s ";
    }
    mHandler.postDelayed(this, 1000);
}

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

ViewHolder viewHolder;
if (convertView == null) {
    LayoutInflater inflater = LayoutInflater.from(context);
    convertView = inflater.inflate(R.layout.row_item, null);
    viewHolder = new ViewHolder();

    viewHolder.name = (TextView) convertView.findViewById(R.id.name);
    viewHolder.startingAt = (TextView) convertView.findViewById(R.id.starting_at);
    convertView.setTag(viewHolder );

} else {

    viewHolder = (ViewHolder) convertView.getTag();

Model current = list.get(position);
viewHolder.name.setText(current.name);

return convertView;
