本文提供了一个使用 Flutter 框架创建 ListView 的示例代码。通过该示例，读者可以了解到如何构建一个包含多个列表项的简单应用，并实现列表项的点击事件以进行页面跳转。

import 'package:flutter/material.dart';
import 'package:flutterdemo/secondscreen.dart';

class ListViewDemo extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: "listview",
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget{

  @override
  State<StatefulWidget> createState() {
    return ListViewState();
  }
}

class ListViewState extends State<HomePage>{

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: AppBar(title: Text("listview")),
      body: ListView(
        children: <Widget>[
          getItem("xxx"),
          new Divider(), //分割线
          getItem("xxx"),
          new Divider(), //分割线
          getItem("xxx"),
        ],
      ),
    );
  }

  Widget getItem(String title) {
    return Container(
      width: 160.0,
      child: new ListTile(
        leading: Icon(Icons.map),
        title: Text(title),
        trailing: Icon(Icons.add),
        subtitle: Text("xxx"),
        onTap: (){
          print("我被点击了");
          //跳转
          Navigator.push(context, new MaterialPageRoute(builder: (context) => SecondScreen()));
        },
      ),
    );
  }
}
