我有一个ListView可以构建多张卡片,在它们的下面,我想添加一个Text小部件,该小部件位于ListView下,但位于页面底部,这意味着您必须向下滚动到最后一张卡片看到它。
Widget _buildCardList() {
return ListView.builder(
itemBuilder: _buildFoodCards,
itemCount: cardList.length,
);
}
@override
Widget build(BuildContext context) {
return Container(
// constraints: BoxConstraints.expand(),
decoration: BoxDecoration(
gradient: LinearGradient(
begin: Alignment.topCenter,
end: Alignment.bottomCenter,
colors: [Color(0xff170422), Color(0xff9B22E6)],
stops: [0.75, 1],
),
),
child: Column(
children: <Widget>[
Expanded(child: _buildCardList()),
Text(
'TEXT THAT SHOULD BE SCROLLABLE UNDER THE LISTVIEW',
style: TextStyle(color: Colors.white),
)
],
),
);
}
此刻,我的文本位于ListView下,但是该文本在页面上是静态的,无法在ListView上滚动。

只需进行一些更改即可使其生效:
shrinkWrap
= true
设置为您的ListView
。physics
= NeverScrollableScrollPhysics
设置为您的ListView
。SingleChildScrollView
添加为您的Column
的父母。Expanded
小部件。代码
Widget _buildCardList() {
return ListView.builder(
shrinkWrap: true,
physics: NeverScrollableScrollPhysics(),
itemBuilder: _buildFoodCards,
itemCount: cardList.length,
);
}
@override
Widget build(BuildContext context) {
return Container(
// constraints: BoxConstraints.expand(),
decoration: BoxDecoration(
gradient: LinearGradient(
begin: Alignment.topCenter,
end: Alignment.bottomCenter,
colors: [Color(0xff170422), Color(0xff9B22E6)],
stops: [0.75, 1],
),
),
child: SingleChildScrollView(
child: Column(
children: <Widget>[
_buildCardList(),
Text(
'TEXT THAT SHOULD BE SCROLLABLE UNDER THE LISTVIEW',
style: TextStyle(color: Colors.white),
)
],
),
),
);
}
希望它会有所帮助:)
