我试图创建一行，其中中心文本有一个最大大小，如果文本内容太大，它适合大小。
我插入TextOverflow。属性来缩短文本并插入三个点…但这并不奏效。
main.dart
import 'package:flutter/material.dart';
void main() {
runApp(new MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
home: new HomePage(),
);
}
}
class HomePage extends StatelessWidget {
@override
Widget build(BuildContext context) => new Scaffold(
appBar: new AppBar(
backgroundColor: new Color(0xFF26C6DA),
),
body: new ListView (
children: <Widget>[
new Card(
child: new Container(
padding: new EdgeInsets.symmetric(horizontal: 16.0, vertical: 18.0),
child: new Row(
children: <Widget>[
new Container(
padding: new EdgeInsets.only(right: 24.0),
child: new CircleAvatar(
backgroundColor: new Color(0xFFF5F5F5),
radius: 16.0,
)
),
new Container(
padding: new EdgeInsets.only(right: 13.0),
child: new Text(
'Text lar...',
overflow: TextOverflow.ellipsis,
style: new TextStyle(
fontSize: 13.0,
fontFamily: 'Roboto',
color: new Color(0xFF212121),
fontWeight: FontWeight.bold,
),
),
),
new Container(
child: new Column(
crossAxisAlignment: CrossAxisAlignment.end,
children: <Widget>[
new Row(
children: <Widget>[
new Text(
'Bill ',
style: new TextStyle(
fontSize: 12.0,
fontFamily: 'Roboto',
color: new Color(0xFF9E9E9E)
),
),
new Text(
'\$ -999.999.999,95',
style: new TextStyle(
fontSize: 14.0,
fontFamily: 'Roboto',
color: new Color(0xFF212121)
),
),
],
),
new Row(
children: <Widget>[
new Text(
'Limit ',
style: new TextStyle(
fontSize: 12.0,
fontFamily: 'Roboto',
color: new Color(0xFF9E9E9E)
),
),
new Text(
'R\$ 900.000.000,95',
style: new TextStyle(
fontSize: 14.0,
fontFamily: 'Roboto',
color: new Color(0xFF9E9E9E)
),
),
],
),
]
)
)
],
),
)
),
]
)
);
}
结果:
预期:
行内文本
1. 第1列的文本首选项>第2列
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Text(
"This is very very long text in column 1 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis, backgroundColor: Colors.green),
),
Flexible(
child: Text("This is very very long text in column 2 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow)),
)
],
)
2. 第2列的文本首选项>第1列
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Flexible(
child: Text(
"This is very very long text in column 1 of Row",
style: TextStyle(overflow: TextOverflow.ellipsis, backgroundColor: Colors.green),
),
),
Text("This is very very long text in column 2 of Row",
style: TextStyle(overflow: TextOverflow.ellipsis, backgroundColor: Colors.yellow))
],
)
3.相同的喜好
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Flexible(
child: Text(
"This is very very long text in column 1 of Row",
style: TextStyle(

),
),
Flexible(
child: Text("This is very very long text in column 2 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow)),
)
],
)
列内的文本
定义maxLine属性。
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Text(
"This is very very very very very very very very very very very very very very very very very long text in Row 1 of Column",
maxLines: 2,
style: TextStyle(
backgroundColor: Colors.green, overflow: TextOverflow.ellipsis),
),
Text("This is very very long text in Row 2 of Column",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow))
],
)
注意:如果你的要求是显示条目内容而不溢出，但不打乱约束，删除溢出属性，但保持Flexible不变:
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Flexible(
child: Text(
"This is very very long text in column 1 of Row",
style: TextStyle(backgroundColor: Colors.green),
),
),
Flexible(
child: Text("This is very very long text in column 2 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow)),
)
],
)
我们首先用容器包装文本，然后用灵活的小部件包装容器，使文本省略号走到第二行
Container(
height: SizeConfig.blockSizeVertical * 10,
width: SizeConfig.blockSizeHorizontal * 88,
child: Row(
crossAxisAlignment:
CrossAxisAlignment.start,
children: [
PicClipper(height: 50, width:50, circularRadius: 30, circularImage:imageUrl[index]),
SizedBox(
width:
SizeConfig.blockSizeHorizontal * 3,
),
Flexible(
child: Container(
child: const
AppText
(
fontSize: 12,
fontWeight: FontWeight.normal,
text:
'Lorem ipsum dolor sit amet,consectetur adipiscing elit.Lorem ipsum dolor sit amet,consectetur adipiscing elit.',
fontStyle: FontStyle.normal,
textColor: AppColors.blackTextColor,
textOverflow: TextOverflow.ellipsis,
fontFamily: "Poppins",
maxLine: 3,
textAlign: TextAlign.start,
),
),
),
],
),
),

在包选型layout_widgets中有一个非常简单的类TextOneLine。
把你的课文放在那堂课上。
例如:
Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
SvgPicture.asset(
loadAsset(SVG_CALL_GREEN),
width: 23,
height: 23,
fit: BoxFit.fill,
),
SizedBox(width: 16),
Expanded(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
TextOneLine(
widget.firstText,
style: findTextStyle(widget.firstTextStyle),
textAlign: TextAlign.left,
),
SizedBox(height: 4),
TextOneLine(
widget.secondText,
style: findTextStyle(widget.secondTextStyle),
textAlign: TextAlign.left,
),
],
),
),
Icon(
Icons.arrow_forward_ios,
color: Styles.iOSArrowRight,
)
],
)
