Android 颤振中可滚动列中的4个水平列表视图
我需要在一个垂直滚动列中有4个可滚动的水平列表视图。 我一次又一次地尝试了多种方法,但是垂直滚动似乎不起作用。 这就是我想要的布局Android 颤振中可滚动列中的4个水平列表视图,android,flutter,listview,dart,flutter-layout,Android,Flutter,Listview,Dart,Flutter Layout,我需要在一个垂直滚动列中有4个可滚动的水平列表视图。 我一次又一次地尝试了多种方法,但是垂直滚动似乎不起作用。 这就是我想要的布局 Container( padding: EdgeInsets.all(20), child: SingleChildScrollView( scrollDirection: Axis.vertical, child: Column( mainAxisSize: Main

谁能告诉我我做错了什么?
我已经在这里面呆了很长时间了。
水平列表确实滚动,但垂直滚动不起作用。尝试使用
SingleChildScrollView
和Row
而不是ListView
比如说,
class Home extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("4 Horizontals"),
),
body: SafeArea(
child: SingleChildScrollView(
child: Column(
children: [
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(10, (index) => getWid()),
),
),
SizedBox(height: 10),
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(10, (index) => getWid()),
),
),
SizedBox(height: 10),
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(10, (index) => getWid()),
),
),
SizedBox(height: 10),
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: List.generate(10, (index) => getWid()),
),
),
],
),
),
),
);
}
Widget getWid() {
return Container(
color: Colors.pink,
width: 200,
height: 200,
padding: EdgeInsets.all(10),
margin: EdgeInsets.all(5),
child: Center(
child: Text(
"Hello",
style: TextStyle(
color: Colors.white,
fontSize: 30
),
),
),
);
}
}
尽管我不得不采取不同的方法,但您的回答确实帮助我发现了原始代码的问题。谢谢
