如何不通过单击通知来打开应用程序？

Question

这是我第一次使用Notification。

使用此代码，我可以阅读Log（）中写的内容：

 RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
    contentView.setTextViewText(R.id.title, "Custom notification");
    contentView.setTextViewText(R.id.text, "This is a custom layout");

    Intent intentDown = new Intent(this, myIntentClass.class);
    intentDown.putExtra("DO", "down");
    PendingIntent pDown = PendingIntent.getActivity(this,0,intentDown,0);
    contentView.setOnClickPendingIntent(R.id.drop_down, pDown);

    Intent intentUp = new Intent(this, myIntentClass.class);
    intentUp.putExtra("DO", "up");
    PendingIntent pUp = PendingIntent.getActivity(this,1,intentUp,0);
    contentView.setOnClickPendingIntent(R.id.drop_up, pUp);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channelSmoke")
            .setSmallIcon(R.drawable.ic_launcher_background)
            .setContent(contentView)
            .setSubText("Sub Text")
            .setPriority(NotificationCompat.PRIORITY_DEFAULT)
            .setOngoing(true);

    NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
    notificationManager.notify(100, builder.build());

这是我的Intent课程：

public class myIntentClass extends Activity {

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    String action = (String) Objects.requireNonNull(getIntent().getExtras()).get("DO");
    assert action != null;
    if (action.equals("down")) {
        Log.d("CLICKED", "DOWN");
        finish();
    }else if(action.equals("up")){
        Log.d("CLICKED"," UP");
        finish();
    }
}
}

但是，当我单击“ R.id.drop_down”或“ R.id.drop_up”按钮时，该应用会打开。可以打开未打开的应用程序（例如使用chromecast的netflix通知）。

编辑：我解决了使用接收器而不是IntentClass的问题。

只需使用Reciever而不是IntentClass
