警报管理器不响

发布于 2024-12-07 17:26:02 字数 1004 浏览 1 评论 0原文

我正在构建一个警报应用程序。为此，我需要提供一个时间作为输入。我正在尝试遵循代码，但警报没有触发。我在网上搜索并修改了很多代码，但仍然没有成功。

有人可以帮我吗。提前致谢。

Intent intent = new Intent(NapAppActivity.this, OnetimeAlarmReceiver.class);
 PendingIntent pendingIntent = PendingIntent.getBroadcast(NapAppActivity.this, 1,  intent, 0);

     Calendar cur_cal = new GregorianCalendar();
    cur_cal.setTimeInMillis(System.currentTimeMillis());

    Calendar cal = new GregorianCalendar();
    cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
    cal.set(Calendar.HOUR_OF_DAY, 12);
    cal.set(Calendar.MINUTE, 17);
    cal.set(Calendar.SECOND, cur_cal.get(Calendar.SECOND));
    cal.set(Calendar.MILLISECOND, cur_cal.get(Calendar.MILLISECOND));
    cal.set(Calendar.DATE, cur_cal.get(Calendar.DATE));
    cal.set(Calendar.MONTH, cur_cal.get(Calendar.MONTH));

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

I'm building an Alarm Application. for it, I'm need to supply a time as input. I'm trying following code but alarm doesnt' trigger. I searched online and modified the code much alot but still no luck.

 PendingIntent pendingIntent = PendingIntent.getBroadcast(NapAppActivity.this, 1,  intent, 0);

     Calendar cur_cal = new GregorianCalendar();
    cur_cal.setTimeInMillis(System.currentTimeMillis());

    Calendar cal = new GregorianCalendar();
    cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
    cal.set(Calendar.HOUR_OF_DAY, 12);
    cal.set(Calendar.MINUTE, 17);
    cal.set(Calendar.SECOND, cur_cal.get(Calendar.SECOND));

我认为您应该使用 cal=Calendar.getInstance() 来获取当前日期/时间，而不是使用 GregorianCalendar 构造函数。

然后，只需设置 HourOfDay 和 Minutes，不要触及其他字段。

<receiver android:name=".OnetimeAlarmReceiver" android:process=":remote" />

您是否在清单中声明了接收者？

还在处的接收者名称之前加上完整的包裹声明。如果您的接收器位于另一个包中，我已使用“。”在上述声明中...

谨致，

<receiver android:name=".OnetimeAlarmReceiver" android:process=":remote" />

have you declared receiver in your manifest.

Also preceed Receiver name with full package declaration at place of . If your Receiver is in another package I have used "." in above declaration ...

With Regards,
