创建水平列表

您可能想要创建一个水平滚动而不是垂直滚动的列表。 ListView 小部件支持水平列表。

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,
              ),
            ],
          ),
        ),
      ),
    );
  }
}
