android - 如何设置警报和通知？

Question

我一直在做我的警报项目..

我的代码是这样的:

    String a = interval.getText().toString();

   Intent myIntent = new Intent(AndroidAlarmService.this, MyAlarmService.class);
   pendingIntent = PendingIntent.getService(AndroidAlarmService.this, 0, myIntent, 0);

            AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

            Calendar calendar = Calendar.getInstance();
            calendar.setTimeInMillis(System.currentTimeMillis());
            calendar.add(Calendar.SECOND, 10);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), Integer.parseInt(a)*1000, pendingIntent);

            NotificationManager mNotificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

            int icon = R.drawable.alarm_icon;
            CharSequence tickerText = "Hello";
            long when = System.currentTimeMillis();

            Notification notification = new Notification(icon, tickerText, when);

            Context context = getApplicationContext();
            CharSequence contentTitle = "My notification";
            CharSequence contentText = "Hello World!";
            Intent notificationIntent = new Intent(AndroidAlarmService.this, AndroidAlarmService.class);
            PendingIntent contentIntent = PendingIntent.getActivity(AndroidAlarmService.this.getBaseContext(), 0, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);

            notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

            final int HELLO_ID = 1;

            mNotificationManager.notify(HELLO_ID, notification);

   Toast.makeText(AndroidAlarmService.this, "Start Alarm", Toast.LENGTH_LONG).show();
  }});

我有一个问题，通知总是出现一次，不会重复出现。

我想设置一个可重复的闹钟和通知，所以每次闹钟激活时，通知也会发出...例如，当我每 1 小时设置一次闹钟，那么每隔一小时，闹钟就会触发器和通知也会出来..

谁能帮帮我？先谢谢

在服务类中传递您的通知，即在 onStartCommand() 中
