Question

我试图在每个星期二上午11点调用一个调度程序，但不知何故下面的代码不起作用。

使用日历对象，我可以获得下一个日程安排＆amp;然后在调度程序中进行设置。

有人能指出下面代码中存在哪些错误？

private static final int PERIOD = 7 * 24 * 60 * 60 * 1000;

DateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss", Locale.ENGLISH);                

Calendar c = nextDayOfWeek(Calendar.TUESDAY); // Set the day of week at which you want to trigger weekly task       

c.set(Calendar.HOUR_OF_DAY, 11); // Set the time at which you want to trigger weekly task
c.set(Calendar.MINUTE, 0);
c.set(Calendar.SECOND,0);       
c.set(Calendar.MILLISECOND,0);          

boolean weeklyAlarmUp = (PendingIntent.getBroadcast(ctxt, 0, new Intent(ctxt, ScheduledWeeklyService.class), PendingIntent.FLAG_NO_CREATE) != null);
if (!weeklyAlarmUp) {   
    Intent i = new Intent(ctxt, ScheduledWeeklyService.class);
    PendingIntent piWeekly = PendingIntent.getBroadcast(ctxt, 0, i, 0);                 
    AlarmManager alarmMgrWeekly = (AlarmManager)ctxt.getSystemService(Context.ALARM_SERVICE);
    alarmMgrWeekly.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), PERIOD, piWeekly);
}

我的实用程序方法如下所示：

public static Calendar nextDayOfWeek(int dow) {
Calendar date = Calendar.getInstance();
int diff = dow - date.get(Calendar.DAY_OF_WEEK);
if (!(diff > 0)) {
    diff += 7;
}
date.add(Calendar.DAY_OF_MONTH, diff);
return date;
}

每周调度程序没有被触发？
