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，即一次性闹钟和每天重复闹钟，我需要根据我的要求设置闹钟。当我设置一次报警它工作正常，但是当我设置重复报警它不工作。我也一直在遵循以下方法，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); 

这里是我的片段一次和重复报警的方法。

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(); 
    } 

这里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());}}

与此尝试。我正在使用它，它工作正常。并且使用服务或意图服务来通知不使用Brodcast。

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); 

     } 

如果你想获取来自服务器的数据，然后张贴通知，然后使用电源管理器和Wakelog成功地显示通知。不要忘记给清单添加WAKE LOG和SET ALARM权限。创建通知后

复位报警：

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); 

     } 
    }
