在Android中设置多个告警触发不同的通知,可以通过以下步骤实现:
Context.getSystemService(Context.ALARM_SERVICE)
方法获取AlarmManager对象。PendingIntent.getActivity()
、PendingIntent.getService()
或PendingIntent.getBroadcast()
方法创建不同的PendingIntent。set()
或setExact()
方法,传入不同的触发时间和对应的PendingIntent,来设置多个告警。以下是一个示例代码:
// 创建AlarmManager对象
AlarmManager alarmManager1 = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
AlarmManager alarmManager2 = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
// 创建不同的PendingIntent
Intent intent1 = new Intent(this, AlarmReceiver.class);
Intent intent2 = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent1 = PendingIntent.getBroadcast(this, 0, intent1, 0);
PendingIntent pendingIntent2 = PendingIntent.getBroadcast(this, 1, intent2, 0);
// 设置触发时间
Calendar calendar1 = Calendar.getInstance();
calendar1.setTimeInMillis(System.currentTimeMillis());
calendar1.set(Calendar.HOUR_OF_DAY, 8);
calendar1.set(Calendar.MINUTE, 0);
calendar1.set(Calendar.SECOND, 0);
alarmManager1.set(AlarmManager.RTC_WAKEUP, calendar1.getTimeInMillis(), pendingIntent1);
Calendar calendar2 = Calendar.getInstance();
calendar2.setTimeInMillis(System.currentTimeMillis());
calendar2.set(Calendar.HOUR_OF_DAY, 12);
calendar2.set(Calendar.MINUTE, 0);
calendar2.set(Calendar.SECOND, 0);
alarmManager2.set(AlarmManager.RTC_WAKEUP, calendar2.getTimeInMillis(), pendingIntent2);
上述代码中,创建了两个AlarmManager对象和两个不同的PendingIntent对象。分别设置了两个触发时间,并通过set()
方法将触发时间和对应的PendingIntent传入,实现了在Android中设置多个告警触发不同的通知。
注意:为了接收到告警触发的通知,需要创建一个继承自BroadcastReceiver的AlarmReceiver类,并在AndroidManifest.xml文件中注册该类。在AlarmReceiver类中可以编写相应的逻辑来处理触发的通知。
