重复警报周特定日期android

在我的应用程序中,我有一个功能,可以在4个senerios中触发警报：

>只有一次用户选择的日期和时间
>每日选择的时间
>每周根据所选日期和时间
>用户选择的一周中的自定义日期

我通过以下方式成功实施了前3个senerios：

只有一次：

Calendar calendar = Calendar.getInstance();

        calendar.set(Calendar.YEAR, Integer.parseInt(date[0]));
        calendar.set(Calendar.MONTH, (Integer.parseInt(date[1])) - 1);
        calendar.set(Calendar.DAY_OF_MONTH, Integer.parseInt(date[2]));
        calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(time[0]));
        calendar.set(Calendar.MINUTE, Integer.parseInt(time[1]));
        calendar.set(Calendar.SECOND, 0);

        alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

对于每日安排：

Calendar calendar = Calendar.getInstance();
            calendar.setTimeInMillis(System.currentTimeMillis());
            calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(time[0]));
            calendar.set(Calendar.MINUTE, Integer.parseInt(time[1]));
            calendar.set(Calendar.SECOND, 0);

            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

对于每周安排(根据系统日期)：

Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());

        calendar.set(Calendar.DAY_OF_WEEK, dayOfWeek);
        calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(time[0]));
        calendar.set(Calendar.MINUTE, Integer.parseInt(time[1]));
        calendar.set(Calendar.SECOND, 0);
        //long interval = calendar.getTimeInMillis() + 604800000L;
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 7, pendingIntent);

对于用户选择的自定义工作日(例如,仅适用于星期一和星期五,每周重复一次)我使用的是与迭代时每周调度相同的代码.但它不适用于星期一(星期五之前设定)和星期五工作.此外,如果今天(系统日期)是星期一或星期五,它不会触发今天的警报.

那么我如何实现每周自定义日的每周警报计划？

解决方法:

您无法告诉警报管理器您想要触发的日期.

一种解决方案是针对您希望每周重复触发一周的每一天发出警报.

因此,对于您的周一和周五场景,您将在周一设置每周重复提醒,并在周五设置每周重复提醒.

示例代码：

private void scheduleAlarm(int dayOfWeek) {

    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.DAY_OF_WEEK, dayOfWeek);

    // Check we aren't setting it in the past which would trigger it to fire instantly
    if(calendar.getTimeInMillis() < System.currentTimeMillis()) {
        calendar.add(Calendar.DAY_OF_YEAR, 7);
    }

    // Set this to whatever you were planning to do at the given time
    PendingIntent yourIntent; 

    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 7, yourIntent);
}

private void setUpAlarms() {

    scheduleAlarm(Calendar.MONDAY);
    scheduleAlarm(Calendar.FRIDAY);
}
