如何对清除所有通知执行一些操作

Question

我想在清除通知时停止媒体播放器，以及当我点击通知时如何打开某些活动

这是我的闹钟功能

    public void alarmstart(String idd,int alarmmonth,int alarmyear,int alarmday,int alarmhour,int alarmmin)
        {
            AlarmManager manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);


 Intent myIntent;
        PendingIntent pendingIntent;

        myIntent = new Intent(Create.this,AlarmNotificationReceiver.class);
        myIntent.putExtra("title",tii);
        myIntent.putExtra("note",noo);
        myIntent.putExtra("id",id);
        pendingIntent = 
        PendingIntent.getBroadcast(this,Integer.valueOf(idd),myIntent,0);


        Calendar cal1=Calendar.getInstance();
        cal1.set(Calendar.MONTH,alarmmonth-1);
        cal1.set(Calendar.YEAR,alarmyear);
        cal1.set(Calendar.DAY_OF_MONTH,alarmday);

        cal1.set(Calendar.HOUR_OF_DAY,alarmhour);
        cal1.set(Calendar.MINUTE,alarmmin);
        cal1.set(Calendar.SECOND,0);

        manager.set(AlarmManager.RTC_WAKEUP,cal1.getTimeInMillis() ,pendingIntent);


    }

这是我的通知类广播接收器

public class AlarmNotificationReceiver extends BroadcastReceiver {

    static MediaPlayer mMediaPlayer;
    PendingIntent pintent;
    static String id;



    @Override
    public void onReceive(Context context, Intent intent) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

        String ti,no;
        ti=intent.getExtras().getString("title");
        no=intent.getExtras().getString("note");
        id=intent.getExtras().getString("id");

        Intent stopSoundIntent = new Intent(context,
                NotificationActionService.class)
                .setAction("Stop");


        PendingIntent stopSoundPendingIntent = PendingIntent.getService(context, 0,
                stopSoundIntent, PendingIntent.FLAG_ONE_SHOT);


       // builder.setAutoCancel(true)
                builder.setDefaults(Notification.DEFAULT_ALL)
                .setWhen(System.currentTimeMillis())
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(ti)
                .setContentText(no)

                .setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND)
                .addAction(new NotificationCompat.Action(R.mipmap.stop,
                        "Stop", stopSoundPendingIntent))


                .setContentInfo("Info");
         mMediaPlayer = MediaPlayer.create(context, R.raw.teri);
         mMediaPlayer.start();

        NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(Integer.valueOf(id),builder.build());


    }

    public static class NotificationActionService extends IntentService {
        public NotificationActionService() {
            super(NotificationActionService.class.getSimpleName());
        }

        @Override
        protected void onHandleIntent(Intent intent) {
            String action = intent.getAction();

            if ("Stop".equals(action)) {
                // TODO: handle action StopSound.
                mMediaPlayer.stop();
                // If you want to cancel the notification:
                NotificationManagerCompat.from(this).cancel(Integer.valueOf(id));
                // NOTIFICATION_ID : you can (set and get) notificationid (to/from) intent
            }

        }

    }
}

请任何人都可以帮助我，我是新手，几乎阅读了与该主题相关的所有以前的帖子，但无法做到这一点 我无法正确使用 deleteintent 以及如何在点击通知时打开活动

Answer 1

点击通知打开活动，

NotificationManager notificationManager = (NotificationManager) context
        .getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);

Intent notificationIntent = new Intent(context, HomeActivity.class);

notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
        | Intent.FLAG_ACTIVITY_SINGLE_TOP);

PendingIntent intent = PendingIntent.getActivity(context, 0,
        notificationIntent, 0);

notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);

要清除点击通知，

notification.flags |= Notification.FLAG_AUTO_CANCEL;

打开 MainActivity 后，您可以执行您的操作。
