我想为我的应用程序中的每个提醒实现多个通知。我在这里发现了一些线索,可以通过每个通知使用唯一的ID来实现,但它不起作用,我只得到一个通知被最后一个通知覆盖。另外我想知道如何在设备重启后保持通知完好无损。这里是我的代码Android多个通知BroadcastReceiver
//call notification activation Intent
Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
AlarmReceiver类
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
//creating unique id for each specific notification
int ID = (int) ((new Date().getTime()/1000L) % Integer.MAX_VALUE);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notification = new Intent(context,MainActivity.class);
notification.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pi = PendingIntent.getActivity(context,0,notification,0);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder mynotification = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_date_range_black_48dp)
.setContentTitle("note taker")
.setContentText("you have a reminder about a note")
.setAutoCancel(true)
.setContentIntent(pi)
.setSound(defaultSoundUri)
.setVibrate(new long[]{1000,1000,1000,1000,1000});
notificationManager.notify(ID,mynotification.build());
}
}
恐怕是行不通的 –
