JavaFX水平添加TilePane中的对象（ScrollPane中的TilePane）

Question

我需要帮助在TilePane（水平地包含在ScrollPane）中插入对象。它会水平插入，直到到达ScrollPane的末尾，然后开始添加到ScrollPane的下一行。这就是它的样子：

该框是ScrollPane，TilePane是保存所有图片的内容。

基本上，我希望TilePane继续向右添加并让ScrollPane显示水平滚动条。

这是我的代码：

private void start()
{
    @FXML private ImageView bigImage;
    @FXML private ScrollPane scrollPane;
    @FXML private TilePane tilePane;

    // Setup scrollpane
    scrollPane.setHbarPolicy(ScrollPane.ScrollBarPolicy.AS_NEEDED);
    scrollPane.setVbarPolicy(ScrollPane.ScrollBarPolicy.NEVER);     
    tilePane.setHgap(15);

    for(int i = 0; i < 10; i++)
    {
        ImageView imageView = new ImageView(bigImage.getImage());
        imageView.setFitWidth(100);
        imageView.setFitHeight(100);

        tilePane.getChildren().add(imageView);
    }

    //scrollPane.setFitToWidth(true);
    scrollPane.setContent(tilePane);
}

FXML：

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.ScrollPane?>
<?import javafx.scene.image.Image?>
<?import javafx.scene.image.ImageView?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.TilePane?>

<AnchorPane prefHeight="700.0" prefWidth="900.0" xmlns="http://javafx.com/javafx/8.0.65" xmlns:fx="http://javafx.com/fxml/1" fx:controller="view.PhotoController">

   <children>       
      <ImageView fx:id="bigImage" fitHeight="441.0" fitWidth="534.0" layoutX="35.0" layoutY="52.0" pickOnBounds="true">
         <image>
            <Image url="@../../../../../../Pictures/Wallpaper02.jpg" />
         </image>
      </ImageView>

      <ScrollPane fx:id="scrollPane" layoutX="35.0" layoutY="528.0" prefHeight="140.0" prefWidth="820.0">
         <content>
            <TilePane fx:id="tilePane" prefHeight="137.0" prefWidth="817.0" />
         </content>
      </ScrollPane>
   </children>

</AnchorPane>

我怎样才能完成我想做的事情？任何帮助，将不胜感激。谢谢！

你可以使用ccs属性＆＃34;重复＆＃34;有了这样的背景，它将完成所有工作：

import java.util.HashMap;
import java.util.Map;
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;


public class SequenceNumber {

 public static int getSequenceNumber (String TcOrderId){

    // Create a hash map to set key values pair.
    Map<String, Integer> map = new HashMap<String, Integer>();  
    int i= 1;

    // check if hashmap contains the key.
    System.out.println("key present " +map.containsKey(TcOrderId));
    if (map.containsKey(TcOrderId))
    {
       //Key Present
       System.out.println("Inside IF ");
       int value = map.get(TcOrderId);
       System.out.println("value from the key " + value);
       map.remove(value);
       map.put(TcOrderId, value+1);
       return map.get(TcOrderId);
    }
    else
    {
        //Key Not present
        System.out.println("INSIDE ELSE ");
        map.put(TcOrderId, i);
        System.out.println("map "+ map);
        return map.get(TcOrderId);
    }
}

public static void main(String[] args) throws IOException {

    String sCurrentLine;
    BufferedReader br = null;
    try {
        br = new BufferedReader(new FileReader("C:\\Users\\BongAn\\Desktop\\Package\\testing.txt"));
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    {
        while ((sCurrentLine = br.readLine()) != null) {
            //String orderid = sCurrentLine.substring(0, 6);
            System.out.println("reading line " +sCurrentLine);
            int seqvalue = getSequenceNumber(sCurrentLine);
            System.out.println("seqvalue "+seqvalue);
        }

    }

}
