安卓开发 分步调试能正常显示，直接运行数据不对

使用NotificationCompat，mErrorCount = adapter.getCount()，将mErrorCount打印出来，
adapter = new TideListViewAdapter(TideMapActivity.this, list);
lvTide.setAdapter(adapter);
lvTide.setOnItemClickListener(tideListOnItemClick);
lvTide.setOnItemLongClickListener(tideListOnItemLongClick);
lvTide.setOnRefreshListener(tideRefreshListener);
mErrorCount = adapter.getCount();

    ///Intent resultIntent = new Intent(this, TideMapActivity.class);
   // resultIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
    //PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
    notifyBuilder = new NotificationCompat.Builder(this)
            /*设置large icon*/
            .setLargeIcon(bitmap)
             /*设置small icon*/
            .setSmallIcon(R.drawable.ic_launcher)
            /*设置title*/
            .setContentTitle("出现异常的监测点个数为")
            /*设置详细文本*/
            .setContentText(String.valueOf(mErrorCount)+"个")
             /*设置发出通知的时间为发出通知时的系统时间*/
            .setWhen(System.currentTimeMillis())
             /*设置发出通知时在status bar进行提醒*/
            .setTicker("有故障监测点")

                        正常运行，mErrorCount一直显示为0，分步调试才能正确显示，什么原因？
