创建水平列表

你可能需要创建可以水平而非垂直滚动的列表。ListView 部件支持水平列表。

使用标准的 ListView 构造函数，传入一个水平的 scrollDirection，它会覆盖默认的垂直方向。

ListView(
  // This next line does the trick.
  scrollDirection: Axis.horizontal,
  children: <Widget>[
    Container(width: 160, color: Colors.red),
    Container(width: 160, color: Colors.blue),
    Container(width: 160, color: Colors.green),
    Container(width: 160, color: Colors.yellow),
    Container(width: 160, color: Colors.orange),
  ],
),

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    const title = 'Horizontal List';

    return MaterialApp(
      title: title,
      home: Scaffold(
        appBar: AppBar(title: const Text(title)),
        body: Container(
          margin: const EdgeInsets.symmetric(vertical: 20),
          height: 200,
          child: ListView(
            // This next line does the trick.
            scrollDirection: Axis.horizontal,
            children: <Widget>[
              Container(width: 160, color: Colors.red),
              Container(width: 160, color: Colors.blue),
              Container(width: 160, color: Colors.green),
              Container(width: 160, color: Colors.yellow),
              Container(width: 160, color: Colors.orange),
            ],
          ),
        ),
      ),
    );
  }
}
