用于一起滚动 Flutter 的水平列表视图列表
[英]List of Horizontal List view to scroll together Flutter
问题描述
I want to create a vertical list of a horizontal list view.
我想创建一个水平列表视图的垂直列表。 I have achieved it using this .我已经使用这个实现了它。 But my issue is that each item is scrolling separately horizontally and I don't want that.但我的问题是每个项目都单独水平滚动，我不想要那样。 I need that complete recycler view scrolls horizontally together.我需要完整的回收器视图水平滚动在一起。 This is the code I'm using.这是我正在使用的代码。
ListView.builder(
itemCount: memberItemArray.length,
shrinkWrap: true,
itemBuilder: (BuildContext context, int index) {
return SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: <Widget>[
scrollItem(
75,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sID),
scrollItem(
200,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sName),
scrollItem(
150,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sMobile),
scrollItem(
150,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sPlan != null &&
memberItemArray[index].sPlan !=
'null' &&
memberItemArray[index].sPlan != ''
? memberItemArray[index].sPlan
: '-'),
scrollItem(
150,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sExpDate != null &&
memberItemArray[index].sExpDate !=
'null' &&
memberItemArray[index].sExpDate !=
''
? memberItemArray[index].sExpDate
: '-'),
scrollItem(
100,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sAmount != null &&
memberItemArray[index]
.sAmount
.toString() !=
'null' &&
memberItemArray[index]
.sAmount
.toString() !=
''
? memberItemArray[index]
.sAmount
.toString()
: '-'),
scrollItem(
100,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sDue != null &&
memberItemArray[index]
.sDue
.toString() !=
'null' &&
memberItemArray[index]
.sDue
.toString() !=
''
? memberItemArray[index]
.sDue
.toString()
: '-'),
],
),
);
})

After 2 days of research, I finally got the answer to this.经过2天的研究，我终于得到了这个答案。 Simply use SingleChildScrollView as a parent giving scroll direction as horizontal and its child will be a sized box whose width will be static as I already know the width of the list view, and inside this sized box, we can directly use the ListView.Builder and child of this ListView.Builder will be simple Row只需使用SingleChildScrollView作为父级，将滚动方向设置为水平，其子级将是一个宽度为静态的大小框，因为我已经知道列表视图的宽度，在这个大小的框内，我们可以直接使用 ListView.Builder 和这个 ListView.Builder 的孩子将是简单的Row
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Container(
margin: EdgeInsets.only(left: 5, right: 5),
child: SizedBox(
width: 975,
child: ListView.builder(
itemCount: memberItemArray.length,
shrinkWrap: true,
itemBuilder: (BuildContext context, int index) {
return Row(
children: <Widget>[
scrollItem(
75,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sID),
scrollItem(
200,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sName),
scrollItem(
150,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sMobile),
scrollItem(
150,
const Color(0x00FFFFFF),
const Color(0x50000000),
memberItemArray[index].sPlan != null &&
memberItemArray[index].sPlan !=
'null' &&
memberItemArray[index].sPlan != ''
? memberItemArray[index].sPlan
