如何清除Android通知？

Question

提前致谢。 我对此并不陌生，所以，我要直截了当，我正在尝试创建一个医疗应用，因此，当此人在通知中点击“否”时，这将转到该应用以编辑其提醒（工作），但是当我点击“是”时，将清除通知，那么，我该怎么做？ 谢谢

PS：我是西班牙用户，对我的英语不好很抱歉:)

    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    Uri uri = intent.getData();

    //Muestra una notificación para ver los detalles en la barra de tareas
    Intent action = new Intent(this, MainActivity.class);
    action.setData(uri);
    PendingIntent operation = TaskStackBuilder.create(this)
            .addNextIntentWithParentStack(action)
            .getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

    //Grabe la descripción de la tarea
    if(uri != null){
        cursor = getContentResolver().query(uri, null, null, null, null);
    }

    String description = "";
    try {
        if (cursor != null && cursor.moveToFirst()) {
            description = ContenidoRecordatorio.getColumnString(cursor, ContenidoRecordatorio.AlarmReminderEntry.KEY_TITLE);
        }
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }

    Intent secondActivityIntent = new Intent(this, MainActivity.class);
    PendingIntent secondActivityPendingIntent = PendingIntent.getActivity(this, 0 , secondActivityIntent, PendingIntent.FLAG_ONE_SHOT);

    Intent thirdActivityIntent = new Intent(this, MainActivity.class);
    PendingIntent thirdActivityPendingIntent = PendingIntent.getActivity(this, 0 , thirdActivityIntent, PendingIntent.FLAG_ONE_SHOT);

    // Muestra la notificacion - ver strings.xml
    Notification note = new NotificationCompat.Builder(this)
            .setContentTitle(getString(R.string.reminder_medicamento))
            .setContentText(description)
            .addAction(R.drawable.ic_add_alert_black_24dp,"Yes",secondActivityPendingIntent)
            .addAction(R.drawable.ic_add_alert_black_24dp,"No",thirdActivityPendingIntent)
            .setSmallIcon(R.drawable.ic_add_alert_black_24dp)
            .setContentIntent(operation)
            .setAutoCancel(true)
            .build();

    manager.notify(NOTIFICATION_ID, note);
}

Answer 1

您应该将通知ID存储在“是”意图的捆绑包中，如下所示：

    Intent secondActivityIntent = new Intent(this, MainActivity.class);
    secondActivityIntent.putExtra("NotificationId",Notification_ID)
    PendingIntent secondActivityPendingIntent = PendingIntent.getActivity(this, 0 , secondActivityIntent, PendingIntent.FLAG_ONE_SHOT);

然后在您的MainActivity中，您应该像这样获得通知的ID：

 int notificationId=getIntent().getIntExtra("NotificaitonId",-1);

然后，如果notificationId不等于-1，则表示此活动是在通知中进行的，因此您可以使用此ID调用notificationManger.cancel（），这样将从状态栏中删除通知：

  if(notificationId!=-1){
            NotificationManager notificationManager= (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            notificationManager.cancel(notificationId);
        }

Answer 2

您可以根据NOTIFICATION_ID清除特定通知

NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.cancel(NOTIFICATION_ID);

要清除所有通知，请使用cancelAll()

NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.cancelAll();
