基本List

顯示數(shù)據(jù)列表是移動(dòng)應(yīng)用程序常見(jiàn)的需求括饶。Flutter包含的 ListView Widget罢艾，使列表變得輕而易舉务漩！

創(chuàng)建一個(gè)ListView

使用標(biāo)準(zhǔn)ListView構(gòu)造函數(shù)非常適合僅包含少量條目的列表咱台。我們使用內(nèi)置的ListTile Widget來(lái)作為列表項(xiàng)巡蘸。

new ListView(
  children: <Widget>[
    new ListTile(
      leading: new Icon(Icons.map),
      title: new Text('Maps'),
    ),
    new ListTile(
      leading: new Icon(Icons.photo_album),
      title: new Text('Album'),
    ),
    new ListTile(
      leading: new Icon(Icons.phone),
      title: new Text('Phone'),
    ),
  ],
);

完整的例子

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final title = 'Basic List';
    
    return new MaterialApp(
      title: title,
      home: new Scaffold(
        appBar: new AppBar(
          title: new Text(title),
        ),
        body: new ListView(
          children: <Widget>[
            new ListTile(
              leading: new Icon(Icons.map),
              title: new Text('Map'),
            ),
            new ListTile(
              leading: new Icon(Icons.photo),
              title: new Text('Album'),
            ),
            new ListTile(
              leading: new Icon(Icons.phone),
              title: new Text('Phone'),
            ),
          ],
        ),
      ),
    );
  }
}

創(chuàng)建一個(gè)水平list

有時(shí)奋隶，您可能想要?jiǎng)?chuàng)建一個(gè)水平滾動(dòng)（而不是垂直滾動(dòng)）的列表。ListView本身就支持水平list悦荒。
在創(chuàng)建ListView時(shí)唯欣，設(shè)置scrollDirection為水平方向以覆蓋默認(rèn)的垂直方向。

new ListView(
  // This next line does the trick.
  scrollDirection: Axis.horizontal,
  children: <Widget>[
    new Container(
      width: 160.0,
      color: Colors.red,
    ),
    new Container(
      width: 160.0,
      color: Colors.blue,
    ),
    new Container(
      width: 160.0,
      color: Colors.green,
    ),
    new Container(
      width: 160.0,
      color: Colors.yellow,
    ),
    new Container(
      width: 160.0,
      color: Colors.orange,
    ),
  ],
)

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final title = 'Horizontal List';

    return new MaterialApp(
      title: title,
      home: new Scaffold(
        appBar: new AppBar(
          title: new Text(title),
        ),
        body: new Container(
          margin: new EdgeInsets.symmetric(vertical: 20.0),
          height: 200.0,
          child: new ListView(
            scrollDirection: Axis.horizontal,
