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(

                          new Text(
                            'Bill  ',
                            style: new TextStyle(

                              color: new Color(0xFF9E9E9E)
                            ),
                          ),
                          new Text(
                            '\$ -999.999.999,95',
                            style: new TextStyle(
                              fontSize: 14.0,

                          new Text(

你应该用一个Flexible来包装你的容器,让你的行知道容器比它的固有宽度窄是可以的。扩展也可以。

Flexible(
  child: new Container(
    padding: new EdgeInsets.only(right: 13.0),
    child: new Text(
      'Text largeeeeeeeeeeeeeeeeeeeeeee',
      overflow: TextOverflow.ellipsis,
      style: new TextStyle(
        fontSize: 13.0,
        fontFamily: 'Roboto',
        color: new Color(0xFF212121),
        fontWeight: FontWeight.bold,
      ),
    ),
  ),
),

我多次使用列中行来解决这样的问题。这里有一个解决这个问题的好方法:

 return Column(
  children: [
    Row(
      children: const [
        Icon(Icons.close, color: Colors.red), // an example icon            
        // use the flexible widget above the padding
        Flexible(
          child: Padding(
            padding: EdgeInsets.symmetric(horizontal: 10.0),
            child: Text(
              "Exemple of text",
              overflow: TextOverflow.ellipsis, // I used ellipsis, but it works with others (fade, clip, etc.)
              maxLines: 1,
            ),
          ),
        ),
      ],
    )
  ],
);

注意,我将Flexible放在填充的上方,因为当文本增加时,填充也会破坏屏幕。只把它放在文本中是没有用的。希望这能有所帮助。

    ),
  ),
),

我认为父容器需要被赋予适当大小的maxWidth。看起来文本框会填充上面给出的任何空间。

使用省略号

Text(
  "This is a long text",
  overflow: TextOverflow.ellipsis,
),


使用消失

Text(
  "This is a long text",
  overflow: TextOverflow.fade,
  maxLines: 1,
  softWrap: false,
),


使用夹

Text(
  "This is a long text",
  overflow: TextOverflow.clip,
  maxLines: 1,
  softWrap: false,
),


注意:

如果你在一行中使用文本,你可以像这样把上面的文本放在扩展内:

Expanded(
  child: AboveText(),
)

你可以这样做

Expanded(
   child: Text(
   'Text',
   overflow: TextOverflow.ellipsis,
   maxLines: 1
   )
)
