Flutter中的水平列表列表 [英] List of horizontal list in Flutter
问题描述
我已遵循教程的要求,并完全实现了水平滚动列表. 现在,我想做的是创建一个垂直列表,其中每一行都是一个水平列表.
I have followed this tutorial and fully implemented a horizontally scrolling list. Now, what I would like to do is to create a vertical list where each row is a horizontal list.
我尝试了不同的方法,但是我一直认为应该可以将水平列表简单地设置为垂直列表的子级,但这是行不通的.
I tried different approaches, but i keep thinking that it should be possible to simply set the horizontal list as a child of the vertical, but it doesnt' work.
我的代码是:
Widget build(BuildContext context) {
return new Scaffold(
body: Container(
margin: EdgeInsets.symmetric(vertical: 20.0),
height: 160.0,
child: ListView(
children: <Widget>[
Text("First line"),
HorizontalList(),
Text("Second line"),
HorizontalList()
],
)
),
drawer: new MyNavigationDrawer(),
);
}
我还尝试将各种水平列表放入ListTiles中,但结果是相同的.
I also tried putting the various horizontal lists inside ListTiles but the result is the same.
推荐答案
我想您想要的是另一个列表中的列表 这是您遵循的示例程序的改编 构建方法类似于:
I guess what you want is a list within a another list Here is the adaptation of the sample program that you have followed The build method is like:
Widget build(BuildContext context) {
Widget horizontalList1 = new Container(
margin: EdgeInsets.symmetric(vertical: 20.0),
height: 200.0,
child: new ListView(
scrollDirection: Axis.horizontal,
children: <Widget>[
Container(width: 160.0, color: Colors.red,),
Container(width: 160.0, color: Colors.orange,),
Container(width: 160.0, color: Colors.pink,),
Container(width: 160.0, color: Colors.yellow,),
],
)
);
Widget horizontalList2 = new Container(
margin: EdgeInsets.symmetric(vertical: 20.0),
height: 200.0,
child: new ListView(
scrollDirection: Axis.horizontal,
children: <Widget>[
Container(width: 160.0, color: Colors.blue,),
Container(width: 160.0, color: Colors.green,),
Container(width: 160.0, color: Colors.cyan,),
Container(width: 160.0, color: Colors.black,),
],
)
);
return new Scaffold(
appBar: new AppBar(
title: new Text(widget.title),
),
body: new Center(
child: new Container(
child: ListView(
scrollDirection: Axis.vertical,
children: <Widget>[
horizontalList1,
horizontalList2,
],
),
),
), // This trailing comma makes auto-formatting nicer for build methods.
);
结果类似于:
