### 1、新建一个fxml界面文件，里面就放置一个ListView ###

对应的Controller为ListViewTestController，css配置文件为ListViewTest.css

<?xml version="1.0" encoding="UTF-8"?>
    
    <?import javafx.scene.control.ListView?>
    <?import javafx.scene.layout.VBox?>
    <VBox alignment="CENTER" stylesheets="@../css/ListViewTest.css" xmlns="http://javafx.com/javafx/8"
          xmlns:fx="http://javafx.com/fxml/1"
          fx:controller="com.nii.desktop.controller.ListViewTestController">
       <children>
          <ListView fx:id="studentListView" maxWidth="500.0" minWidth="500.0" prefHeight="300.0" prefWidth="490.0" />
       </children>
    </VBox>

### 2、ListViewTestController代码 ###

将界面的数据映射为dataList，更改界面数据，只需更改dataList值就可以，代码如下

package com.nii.desktop.controller;
    
    import javafx.collections.FXCollections;
    import javafx.collections.ObservableList;
    import javafx.fxml.FXML;
    import javafx.fxml.Initializable;
    import javafx.scene.control.ListView;
    
    import java.net.URL;
    import java.util.ResourceBundle;
    
    /**
     * Created by wzj on 2017/11/1.
     */
    public class ListViewTestController implements Initializable
    {
        /**
         * listview
         */
        @FXML
        private ListView studentListView;
    
        /**
         * listciew数据
         */
        private ObservableList<String> dataList = FXCollections.observableArrayList();
    
        /**
         * Called to initialize a controller after its root element has been
         * completely processed.
         *
         * @param location  The location used to resolve relative paths for the root object, or
         *                  <tt>null</tt> if the location is not known.
         * @param resources The resources used to localize the root object, or <tt>null</tt> if
         */
        @Override
        public void initialize(URL location, ResourceBundle resources)
        {
            studentListView.setItems(dataList);
    
            dataList.add("张三");
            dataList.add("李四");
            dataList.add("王五");
            dataList.add("李华");
    
            dataList.add("张三");
            dataList.add("李四");
            dataList.add("王五");
            dataList.add("李华");
    
            dataList.add("张三");
            dataList.add("李四");
            dataList.add("王五");
            dataList.add("李华");
    
        }
    }

### 3、CSS样式设置 ###

主要是设置界面字体的颜色、字体和行高

.list-cell{
        -fx-text-fill: #292e34;
        -fx-font-family: Arial;
        -fx-pref-height: 30px;
    }

最终的效果如下：
