Question

当我在每周不起作用的情况下设置警报时，我已经有很多联系，但没有一个是成功的。这里是我的代码。

public void forday(int week, int hour, int minuts, int position, int formate) {

        Calendar calSet = Calendar.getInstance();
        Calendar  now=Calendar.getInstance();

        calSet.set(Calendar.DAY_OF_WEEK,week);
        calSet.set(Calendar.HOUR_OF_DAY, hour);
        calSet.set(Calendar.MINUTE, minuts);
        calSet.set(Calendar.AM_PM, formate);
        calSet.set(Calendar.SECOND, 0);
        calSet.set(Calendar.MILLISECOND,0);

        if (calSet.before(Calendar.getInstance())){
             calSet.add(Calendar.DAY_OF_MONTH,7);
        }

        alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE);
        Intent intent = new Intent(context, AlarmReceiver.class);
        int pos = position + week + 1028;
        intent.putExtra("extra", "yes");
        pendingIntent = PendingIntent.getBroadcast(context, pos, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calSet.getTimeInMillis(), 24 * 60 * 60 * 1000, pendingIntent);
}

Answer 1

替换代码行

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calSet.getTimeInMillis(), 24 * 60 * 60 * 1000, pendingIntent);

使用

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), calSet.getTimeInMillis(), pendingIntent);

还有一种简单的方法可以使用AlarmManager.INTERVAL_DAY

每周安排一次警报

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), AlarmManager.INTERVAL_DAY * 7, pendingIntent);

下面添加了一些工作代码，以用于测试目的，在当前时间后2分钟设置警报。

        Calendar next = Calendar.getInstance();
        Calendar now = Calendar.getInstance();
        int nowWeek = now.get(Calendar.DAY_OF_WEEK);
        int nowMinute = now.get(Calendar.MINUTE);
        int nowDay = now.get(Calendar.HOUR_OF_DAY);
        int nowFormat = now.get(Calendar.AM_PM);
        next.set(Calendar.DAY_OF_WEEK, nowWeek);
        next.set(Calendar.HOUR_OF_DAY, nowDay);
        next.set(Calendar.MINUTE, nowMinute + 2);
        next.set(Calendar.AM_PM, nowFormat);
        next.set(Calendar.SECOND, 0);
        if (now.after(next)) {
            // Added a day
            next.add(Calendar.DATE, 1);
        }

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        Intent intent = new Intent(this, AlarmReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 1, intent, PendingIntent.FLAG_CANCEL_CURRENT);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, next.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
