Following this link: Scrollview can host only one direct child,
I do "Wrap all the children inside of another LinearLayout with wrap_content for both the width and the height and vertical orientation."; however I still get that exception. The following is my layout code:

What is the bug here?
it seems related to ScrollView properties.
The following code works:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".MainActivity">

I'm aware that similar questions have been asked on Stackoverflow before, but none of the answers I've found seem to fix my problem. Also I'd like to add that I'm entirely new to javafx and started coding java literally a week ago altogether, so I apologize for any silly errors in my code!
When trying to move an ImageView in my javafx, moving a player and crates around in the game "sokoban", I get a nullpointerexception stating that my ImageView, marked with an fx:id in scene builder and then called on in my controller class, is a null object. Here's my code:
Application:
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class App extends Application{
#Override
public void start(final Stage primaryStage) throws Exception {
primaryStage.setTitle("Sokoban");
primaryStage.setScene(new Scene(FXMLLoader.load(App.class.getResource("StartScreen.fxml"))));
primaryStage.show();
}
public static void main(final String[] args) {
App.launch(args);
}
}

I want to be able in my execution time to hide any buttons and that the buttons adjust automatically filling the blank space that the hidden button leaves.
I've tried using in the MenuController.java instructions like opcParlking.setVisible(false) but it leave me a blank space. This the picture imagen 2.
How can I fix this?
You will want to assign an fx:id to your VBox as well and then inject it into your controller:
#FXML
private VBox vBox;
Then, in your controller, instead of setting a node visible or not, just remove it from the VBox:
vBox.getChildren().remove(opcParlking);
This will remove the node entirely, instead of just making it invisible. Therefore, you will not have the empty space.
So I have a stylesheet with just one style within at the moment for testing purposes.
CSS code:
.minimizeBtn{
-fx-background-color: rgba(0,0,0,1);
}
Setting the ID of the button. This is in the controller for the stage.
public void initialize(URL url, ResourceBundle rb) {
handler = new DbHandlers();
minimizeBtn1.setId("minimizeBtn");
My buttons in fxml:
<Button fx:id="minimizeBtn1" layoutX="520.0" mnemonicParsing="false"
prefHeight="25.0" prefWidth="12.0" styleClass="minimizeBtn" text="Button" />
<Button layoutX="548.0" mnemonicParsing="false" prefHeight="25.0" prefWidth="12.0" styleClass="maximizeBtn" text="Button" />
<Button layoutX="574.0" mnemonicParsing="false" prefHeight="25.0" prefWidth="12.0" styleClass="closeBtn" text="Button" />

The reason i have the styleclass on the buttons is because I have tried both setting the css through class name and ID.
Here's an image of the css working in JavaFx scene builder:
CSS Applying in scene builder.
Here's an imagee of it failing to apply when you run the program:
Not applying
So the answer to this question is to add the following to your start function:
scene.getStylesheets().add(getClass().getResource("pathtostylesheet").toExternalForm());

ImageViews are not resizeable, but you could use a parent that is resizeable and bind the fitWidth and fitHeight properties to the size of the parent using expression binding:
The following example is just a StackPane that could be used as root of a scene to observe the behaviour when resizing the Stage but the same effects would occur, if the StackPane is resized by a Parent, like GridPane:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.image.*?>
<?import javafx.scene.layout.*?>
<StackPane fx:id="root" xmlns:fx="http://javafx.com/fxml/1">
<children>
<ImageView fitWidth="${root.width}" fitHeight="${root.height}" preserveRatio="true">
<!-- ^^ bind to size of node with fx:id="root" ^^ -->
<image>
<Image url="http://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png?v=c78bd457575a"/>

</ImageView>
</children>
</StackPane>

Parent root = FXMLLoader.load(getClass().getResource("/application/MyView.fxml"));
