如何清除Android通知？

Question

提前致謝。 我對此並不陌生，所以，我要直截了當，我正在嘗試創建一個醫療應用，因此，當此人在通知中點擊“否”時，這將轉到該應用以編輯其提醒（工作），但是當我點擊“是”時，將清除通知，那么，我該怎么做？ 謝謝

PS：我是西班牙用戶，對我的英語不好很抱歉:)

    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

您應該將通知ID存儲在“是”意圖的捆綁包中，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，您應該像這樣獲得通知的ID：

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

然后，如果notificationId不等於-1，則表示此活動是在通知中進行的，因此您可以使用此ID調用notificationManger.cancel（），這樣將從狀態欄中刪除通知：

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

Answer 2

您可以根據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，請使用cancelAll()

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