如何在android中安排重复闹钟和一次闹钟

Question

我的应用程序包含两种方法，即一次闹钟和每天重复闹钟，我需要根据我的要求设置闹钟。当我设置一个时间警报时它工作正常，但当我设置重复警报时它不工作。我也研究过以下方法，但它确实对我有用。

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, hour); // hour - user selected hour
calendar.set(Calendar.MINUTE, minute);  // minute -user selected minute
// setRepeating() lets you specify a precise custom interval--in this case,
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
    AlarmManager.INTERVAL_DAY, alarmIntent);

这是我的片段中一次重复警报的方法。

 private SimpleDateFormat EEE_DD_MMM_YYYY_HH_MM_SS_A_Formatter = new SimpleDateFormat("EEE, dd MMM yyyy hh:mm:ss a"); //Tue, 07 Mar 2017 10:50:00 a.m.
PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity().getBaseContext(), alarmId, intent, 0); // where alarmId is autoIncrement 
    AlarmManager alarmManager = (AlarmManager) getActivity().getSystemService(ALARM_SERVICE);
    try {
        Date alarmDate = EEE_DD_MMM_YYYY_HH_MM_SS_A_Formatter.parse(getDateTime()); // where we get both time and date from both pickers respectively.
        if (oneTimeAlarm) { 
        Logs.i(TAG,"one time alarm");
        alarmManager.set(AlarmManager.RTC_WAKEUP, alarmDate.getTime(), pendingIntent);
        Log.i(TAG,"one time alarm set!");
        } else {
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, alarmDate.getTime(), AlarmManager.INTERVAL_DAY, pendingIntent);
            Log.i(TAG,"repeat alarm set!");
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

这是我的报警接收器类文件

public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {

    Vibrator vib = (Vibrator) context.getSystemService(context.VIBRATOR_SERVICE);    //for Vibration
    vib.vibrate(2000);
 showNotification(context);
}

private void showNotification(Context context) {
    Intent intent = new Intent(context, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context,alarmId,intent, 0);

    //  NotificationCompat
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(context)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("Title")
                    .setContentText("text");
    mBuilder.setContentIntent(contentIntent);
    mBuilder.setDefaults(Notification.DEFAULT_SOUND);
    mBuilder.setAutoCancel(true);
    NotificationManager mNotificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(1, mBuilder.build());}}

试试这个。我正在使用它，它工作正常。并使用 Service 或 Intent 服务来抛出不使用 Brodcast 的通知。

    AlarmManager al;
    PendingIntent fintent;
    Calendar calendar;
    Intent notif;
    long _alarm;




    Calendar now = Calendar.getInstance();
        Calendar wakeupcall = Calendar.getInstance();
        wakeupcall.setTimeInMillis(System.currentTimeMillis());
        wakeupcall.set(Calendar.HOUR_OF_DAY, 12);
        wakeupcall.set(Calendar.MINUTE, 30);

        if (wakeupcall.getTimeInMillis() <= now.getTimeInMillis())
            _alarm=wakeupcall.getTimeInMillis() + (AlarmManager.INTERVAL_DAY+1);
        else
            _alarm=wakeupcall.getTimeInMillis();

al = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        notif= new Intent(this,TestNotifyService.class);
        fintent = PendingIntent.getService(this,0,notif,0);

        if (SDK_INT < Build.VERSION_CODES.KITKAT) {
            al.set(AlarmManager.RTC_WAKEUP,_alarm, fintent);

        }
        else if (Build.VERSION_CODES.KITKAT <= SDK_INT  && SDK_INT < Build.VERSION_CODES.M) {
            al.setExact(AlarmManager.RTC_WAKEUP,_alarm,fintent);

        }
        else if (SDK_INT >= Build.VERSION_CODES.M) {
            al.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP,_alarm,fintent);

        }

如果您想从服务器获取数据然后发布通知，请使用电源管理器和唤醒日志成功显示通知。并且不要忘记在清单中添加 WAKE LOG 和 SET ALARM 权限。

创建通知后重置警报：

private void reSETNOTIFY() {

        Calendar now = Calendar.getInstance();
        Calendar wakeupcall = Calendar.getInstance();
        wakeupcall.setTimeInMillis(System.currentTimeMillis());
        wakeupcall.set(Calendar.HOUR_OF_DAY, 12);
        wakeupcall.set(Calendar.MINUTE, 29);

        if (wakeupcall.getTimeInMillis() <= now.getTimeInMillis())
            _alarm=wakeupcall.getTimeInMillis() + (AlarmManager.INTERVAL_DAY+1)+25000;
        else
            _alarm=wakeupcall.getTimeInMillis()+25000;

        al = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        notif= new Intent(this,TestNotifyService.class);
        fintent = PendingIntent.getService(this,0,notif,0);

        if (SDK_INT < Build.VERSION_CODES.KITKAT) {
            al.set(AlarmManager.RTC_WAKEUP,_alarm, fintent);

        }
        else if (Build.VERSION_CODES.KITKAT <= SDK_INT  && SDK_INT < Build.VERSION_CODES.M) {
            al.setExact(AlarmManager.RTC_WAKEUP,_alarm,fintent);

        }
        else if (SDK_INT >= Build.VERSION_CODES.M) {
            al.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP,_alarm,fintent);

        }
    }
