【中文标题】滚动小部件内的颤振滚动小部件【英文标题】：Flutter Scrolling widget inside a Scrolling widget 【发布时间】：2019-05-23 18:21:47 【问题描述】：你好我正在建立这个页面https://cdn.discordapp.com/attachments/460823618805563392/526802427836366848/unknown.png
ListView.builder(
shrinkWrap: true,
itemCount: 1,
itemBuilder: (BuildContext context, int index)
return new Column(
children: <Widget>[
new RopSayac(MediaQuery.of(context).size.width),
stackvideos(),
],
);
,
)
这是我的第一个列表视图，堆栈视频中还有另一个列表视图。
new CustomScrollView(
slivers: <Widget>[
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index)
return new VideoTile();
,
),
),
],
),
Video tile 是返回图像和文本的普通组件

【参考方案1】：您可以利用 CustomScrollView 小部件并更改布局：
改变这个：
ListView.builder(
shrinkWrap: true,
itemCount: 1,
itemBuilder: (BuildContext context, int index)
return new Column(
children: <Widget>[
new RopSayac(MediaQuery.of(context).size.width),
stackvideos(),
],
);
,
)
new CustomScrollView(
slivers: <Widget>[
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index)
return new VideoTile();
,
),
),
],
),
到这里：
CustomScrollView(
slivers: <Widget>[
SliverToBoxAdapter(
child: RopSayac(MediaQuery.of(context).size.width),
),
SliverFixedExtentList(
itemExtent: 50.0,
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index)
return new VideoTile();
,
),
),
],
)
