Android 带有计时器的自定义listview适配器在滚动时刷新

我已经创建了一个定制的listview适配器来安装一个按钮、一个定制的计时器和一个textview。当我滚动我的listview时，“隐藏”的行会自动刷新，所以计时器会自动刷新，即使计时器被隐藏，我如何保持计时器运行？ 我是Android开发的新手，所以我可能做错了什么；我知道listview在滚动时会刷新它的行，但也许我在后台运行计时器时遗漏了一些东西

public class MyCustomAdapter extends BaseAdapter {

    ArrayList<String> users;
    Context context;
    LayoutInflater inflater = null;

    public MyCustomAdapter(Activity mainActivity, ArrayList<String> usersList) {
        // TODO Auto-generated constructor stub
        users = usersList;
        context = mainActivity;
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return users.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return users.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    private class Holder {

        TextView tv;
        CustomChrono cr;
        Button but;
    }

    @Override
    public View getView(final int position, View convertView, final ViewGroup parent) {
        // TODO Auto-generated method stub
        final Holder holder = new Holder();
        View rowView;
        rowView = inflater.inflate(R.layout.customized_list_view, null);

            holder.tv = (TextView) rowView.findViewById(R.id.names_laps);
            holder.cr = (CustomChrono) rowView.findViewById(R.id.chronometer_laps);
            holder.but = (Button) rowView.findViewById(R.id.stop_button);
            holder.cr.start();
            holder.but.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    //((ListView) parent).performItemClick(v, position, 0);
                    holder.cr.stop();
                    stopped = true;

                }
            });


            holder.tv.setText(users.get(position));

        rowView.setTag(holder);
        return rowView;
    }

公共类MyCustomAdapter扩展了BaseAdapter{

排气充气机=空；
公共MyCustomAdapter（活动mainActivity，ArrayList usersList）{
//TODO自动生成的构造函数存根

rowView=充气机。充气（R.layout.customized\u list\u视图，空）；
holder.tv=（TextView）rowView.findViewById（R.id.names\u laps）；
holder.cr=（CustomChrono）rowView.findViewById（R.id.天文计\u圈）；
holder.but=（按钮）rowView.findViewById（R.id.stop_按钮）；
holder.cr.start（）；
holder.but.setOnClickListener（新视图.OnClickListener（）{
@凌驾
公共void onClick（视图v）{
//（（ListView）父级）.performItemClick（v，位置，0）；
保持架。铬停止（）；
停止=真；
}
});
holder.tv.setText（users.get（position））；
rowView.setTag（支架）；
返回行视图；
}

}

然后我有了我的活动类，在这里我使用这个适配器

    runners_arrList = new ArrayList<Runner>(runner_array.size());
    for (String r : runner_array)
    {
        runners_arrList.add(new Runner(r));
    }
    for (int f = 0; f < runners_arrList.size();f++)
    {
        Log.d("Runner: " + f,runners_arrList.get(f).getName());
    }
    m = getIntent().getExtras().getString("booly");

    for (int j = 0; j < runner_array.size(); j++) {
        Runner r = new Runner(runner_array.get(j));
        map.put(r, runner_array.get(j));
    }
    if (m!= null)
    {
        stopped = true;
    }

    list = (ListView) findViewById(R.id.laps_list);
    final MyCustomAdapter adapter = new MyCustomAdapter(RunnerLaps.this,runner_array);
    list.setAdapter(adapter);

                    startActivity(i);
                }
                else
