Question

我想每天重复设置3个不同的闹钟。（如上午9:00至下午1:00至下午6:00）我为他们创造了按钮。我点击按钮时可以设置闹钟的时间。问题是如何更改我的代码以实现上述目的。

private void setNotification() {
    Intent myIntent = new Intent(getActivity(), MyReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), 0, myIntent, 0);
    AlarmManager alarmManager = (AlarmManager)getActivity().getSystemService(Context.ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, set_hour);
    calendar.set(Calendar.MINUTE, set_minute);
    calendar.set(Calendar.SECOND,00);
    long startUpTime = calendar.getTimeInMillis();
    System.out.println(startUpTime + "time" + System.currentTimeMillis());
        if (System.currentTimeMillis() > startUpTime) {
            startUpTime = startUpTime + AlarmManager.INTERVAL_DAY;
        }
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, startUpTime, AlarmManager.INTERVAL_DAY , pendingIntent);
}

Answer 1

据我所知，您只需点击一下按钮即可设置闹钟。使用以下两种方法设置警报和取消警报。要重复警报，请在getBroadcast中使用唯一的请求代码，并在取消时使用相同的请求代码值来取消最初用于启动它的警报。

单击该按钮时，调用setAlarm方法。

public void setAlarm(Calendar time,int pk) {
        AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        Intent alarmIntent = new Intent(context, AlarmReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, pk, alarmIntent, 0);
        manager.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), pendingIntent);
    }


public void cancelAlarm(int pk) {
        AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        Intent alarmIntent = new Intent(context, AlarmReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, pk, alarmIntent, 0);
        manager.cancel(pendingIntent);
    }

    public void cancelAlarm(Context context) {
        // If the alarm has been set, cancel it.
        if (alarmManager != null) {

                minute = Const.ALARM_MINUTE_TIME[0];

        calendar.set(Calendar.HOUR_OF_DAY, hour);
        calendar.set(Calendar.MINUTE, minute);
        calendar.set(Calendar.SECOND, 0);

        Log.d("MyAlarm", "Next Alarm: " + hour + ":" + minute);

        return calendar;
