默认值:setPolicyDataEnable(enabled = true)是什么？

Question

我写了一个时间跟踪应用程序,在logcat中经常可以看到:

我有定时器的listview,每行有单独的线程.计数发生在单独的线程中,它们向处理程序发送空消息(仅用于激活他).这是我的模型中的代码片段:

private String name;
private  Boolean isStart=false, isFinished=false;
private Long elapsedTime=0L,seconds=0L,hours=0L,minutes=0L,lastPause=0L,updateTime=0L,startTime=0L,days=0L,limitTime=0L;
class TrackerThread extends Thread{
    public TrackerThread() {
        super();
    }

    @Override
    public void run() {
        super.run();
        try {
            while (isStart){
            if (isStart && startTime != 0) {
                if (elapsedTime != 0 && updateTime == 0)
                    lastPause = elapsedTime;
                updateTime = ((System.currentTimeMillis() - startTime) + lastPause);
                seconds = updateTime / 1000;
                minutes = seconds / 60;
                hours = minutes / 60;

                seconds = seconds % 60;
                minutes = minutes % 60;
                hours = hours % 24;

                elapsedTime = updateTime;
                handler.sendEmptyMessage(1);
                sleep(1000);

            }
            }
        }catch (Exception ex){
            ex.printStackTrace();
        }
    }
}
Handler handler = new Handler(new Handler.Callback() {
    @Override
    public boolean handleMessage(Message msg) {
        holder.days.setText(String.format("%04d", days));
            holder.hours.setText(String.format("%02d", hours));
            holder.minutes.setText(String.format("%02d", minutes));
            holder.seconds.setText(String.format("%02d", seconds));

        if(limitTime!=0 && elapsedTime>limitTime) {
            isFinished = true;
            holder.stop.setVisibility(View.GONE);
            holder.textFinish.setVisibility(View.VISIBLE);
            holder.limDay.setVisibility(View.GONE);
            holder.limMin.setVisibility(View.GONE);
            holder.limHours.setVisibility(View.GONE);
            holder.textLimit.setVisibility(View.GONE);
            RemindMe.db.execSQL(Util.concat("UPDATE trackers SET isFinish=1, elapsedTime=",limitTime," WHERE _id=",getId()));
        }
        return true;
    }
});
