如何在一屏中使用多滚动-Flutter
how to use multi scroll in one screen -Flutter
我想像 trello 一样在 flutter 中创建一个网页 ui，因为我想要一个水平主滚动条和一个垂直辅助滚动条，但我无法在列中垂直滚动我附加了我想要创建的内容和我的代码，如果您仍然不明白，请告诉我
这是我的代码：-
class PlaningWeekScreenWeb extends StatelessWidget {

Expanded(child: _getSideMenu()),

),
],
);
}
Widget _getMainScreen() {

这是我的卡片小工具：-
class PlaningDayCard extends StatelessWidget {

required this.device,
required this.onTap,

: super(key: key);
final Device device;
final double width;
final Function onTap;
@override
Widget build(BuildContext context) {
return ResponsiveWidget(
mobile: _getMobileCard(),
tablet: _getWebCard(),
desktop: _getWebCard(),

}
Widget _getWebCard() {
return SizedBox(
width: width - 2,
child: Card(

child: InkWell(
onTap: () {
onTap.call();
},
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Row(
children: [
Expanded(
child: "Scrubbing sinks, tubs, showers"
.h2(weight: FontWeight.w700, size: 15),
),
],
),
(6.0).addHSpace(),
Row(
children: [
ImageAssetIconWithColor(

image: ImageIcons.icTriangle,
),
(8.0).addWSpace(),
Expanded(
child: "Main Office".h2(
weight: FontWeight.w500,

size: 14),
),
],
),
(8.0).addWSpace(),
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [

}
Widget _getMobileCard() {
return SizedBox(

完成运行代码：
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: SafeArea(
child: SingleChildScrollView(
child: Container(
height: 200,
child: GridView.count(
scrollDirection: Axis.horizontal,
crossAxisCount: 1 ,
children: List.generate(50,(index){
return Container(
child: Card(
child: ListView(
shrinkWrap: true,
scrollDirection: Axis.vertical,
children: <Widget>[
Container(
width: 50,
height: 100,
color: Colors.yellowAccent,
),
Container(
width: 50,
height: 100,
color: Colors.blue,
),
Container(
width: 50,
height: 100,
color: Colors.green,
),
Container(
width: 50,
height: 100,
color: Colors.red,
),Container(
width: 50,
height: 100,
color: Colors.yellowAccent,
),
Container(
width: 50,
height: 100,
color: Colors.blue,
),
Container(
width: 50,
height: 100,
color: Colors.green,
),
Container(
width: 50,
height: 100,
color: Colors.red,
)
],
),
color: Colors.amber,
),
);
}),
),
) ),
),
),
);
}
}
class myScroll extends MaterialScrollBehavior {
@override
Set<PointerDeviceKind> get dragDevices => {
PointerDeviceKind.touch,
PointerDeviceKind.mouse,
};
}
用 SingleChildScrollView 环绕您要滚动的每个页面。
还要提到 scrollDirection: Axis.vertical.
希望有用！ :)
You can achieve this with more than one ways. But I think the simplest way is that make Row as parent widget put all the ListView in Row after wrapping every ListView by Expanded widget.
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Padding(
padding: const EdgeInsets.symmetric(horizontal: 10.0),
child: Row(
children: <Widget>[
Expanded(
child: ListView.separated(
itemCount: 10,
controller: ScrollController(),
separatorBuilder: (_, __) => const SizedBox(height: 10),
itemBuilder: ((context, index) => Container(
height: 80,
width: double.infinity,
color: Colors.red,
)),
),
),
const SizedBox(width: 10),
Expanded(
child: ListView.separated(
controller: ScrollController(),
itemCount: 2,
separatorBuilder: (_, __) => const SizedBox(height: 10),
itemBuilder: ((context, index) => Container(
height: 100,
width: double.infinity,
color: Colors.yellow,
)),
),
),
const SizedBox(width: 10),
Expanded(
child: ListView.separated(
controller: ScrollController(),
itemCount: 6,
separatorBuilder: (_, __) => const SizedBox(height: 10),
itemBuilder: ((context, index) => Container(
height: 70,
width: double.infinity,
color: Colors.green,
)),
),
)
],
),
),
);
}
- 首先必须用单个滚动子视图包装它。
- 然后把它包成行，
- 然后将其包装在 ListView 中
- 使用扩展，这样一切都可以看到。
希望这对你有用。
