如何在 Android 中使用闹钟管理器设置周一闹钟

Question

我正在尝试在星期一设置闹钟，但它无法正常工作，所以如何在星期一只设置一次闹钟。

if (chk_wednesday.isChecked()) {
                        weekday = 7 - calNow.get(Calendar.DAY_OF_WEEK);
                        calSet.add(Calendar.DATE, weekday);
                        forday(weekday);
                        }

public void forday(int week) {
                days = calNow.get(Calendar.DAY_OF_MONTH);
                month = calNow.get(Calendar.MONTH);
                year = calNow.get(Calendar.YEAR);
        calSet.set(Calendar.DAY_OF_WEEK, week);
        calSet.set(Calendar.HOUR_OF_DAY, hour);
        calSet.set(Calendar.MINUTE, minuts);
        calSet.set(Calendar.SECOND, 0);
        calSet.set(Calendar.MILLISECOND, 0);
        calSet.set(Calendar.DAY_OF_MONTH, days);
        calSet.set(Calendar.MONTH, month);
        calSet.set(Calendar.YEAR, year);
        if (calSet.compareTo(calNow) <= 0) {
            // Today Set time passed, count to tomorrow
            calSet.add(Calendar.DATE, 1);
        }
        Log.i("time1", "" + calSet.getTimeInMillis());
        alarmManager.set(AlarmManager.RTC_WAKEUP, calSet.getTimeInMillis(),
                pendingIntent);
    }

任何人都能帮助我。提前致谢

我会这样做，其中day_of_week、hour、minute定义您希望闹钟发生的日期和时间。将 calSet 设置为本周的适当时间。然后，如果该时间已过本周，则添加一周，以便将其设置为下周的适当时间。

calNow = Calendar.getInstance();
calSet = Calendar.getInstance();
calSet.set(Calendar.DAY_OF_WEEK, day_of_week);
calSet.set(Calendar.HOUR_OF_DAY, hour);
calSet.set(Calendar.MINUTE, minute);
calSet.set(Calendar.SECOND, 0);
calSet.set(Calendar.MILLISECOND, 0);
if (calSet.before(calNow)) {
    nextAlarm.add(Calendar.WEEK_OF_YEAR, 1);
}
