颤振-在溢出时换行文本，如插入省略号或渐隐

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)
                            ),
                          ),
                        ],
                      ),
                    ]

当前回答

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。

其他回答

您可以使用此代码片段来显示带有省略号的文本

Text(
    "Introduction to Very very very long text",
    maxLines: 1,
    overflow: TextOverflow.ellipsis,
    softWrap: false,
    style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold),
),

如果您只是将文本作为列的子(ren)，这是自动换行文本的最简单方法。假设你没有更复杂的问题。在这些情况下，我认为您应该创建适合的容器大小，并在其中放入另一列，然后放入文本。这似乎工作得很好。容器希望缩小到其内容物的大小，这似乎与需要更多努力的包装自然冲突。

Column(
  mainAxisSize: MainAxisSize.min,
  children: <Widget>[
    Text('This long text will wrap very nicely if there isn\'t room beyond the column\'s total width and if you have enough vertical space available to wrap into.',
      style: TextStyle(fontSize: 16, color: primaryColor),
      textAlign: TextAlign.center,),
  ],
),

1. 剪辑

剪切溢出文本以适合其容器。

SizedBox(
          width: 120.0,
          child: Text(
            "Enter Long Text",
            maxLines: 1,
            overflow: TextOverflow.clip,
            softWrap: false,
            style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
          ),
        ),

输出:

2.褪色

将溢出的文本淡出为透明。

SizedBox(
          width: 120.0,
          child: Text(
            "Enter Long Text",
            maxLines: 1,
            overflow: TextOverflow.fade,
            softWrap: false,
            style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
          ),
        ),

输出:

3.省略

使用省略号表示文本已溢出。

SizedBox(
          width: 120.0,
          child: Text(
            "Enter Long Text",
            maxLines: 1,
            overflow: TextOverflow.ellipsis,
            softWrap: false,
            style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
          ),
        ),

输出:

4.可见

在容器外渲染溢出的文本。

SizedBox(
          width: 120.0,
          child: Text(
            "Enter Long Text",
            maxLines: 1,
            overflow: TextOverflow.visible,
            softWrap: false,
            style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
          ),
        ),

在列中，我们通过使用flexibale widget包装列来实现文本省略，

 Container(
            height: SizeConfig.blockSizeVertical * 20,
            width: SizeConfig.blockSizeHorizontal * 88,
            child: Flexible(
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  PicClipper(
                      height: 50,
                      width: 50,
                      circularRadius: 30,
                      circularImage: imageUrl[index]),
                  SizedBox(
                    width: SizeConfig.blockSizeHorizontal * 3,
                  ),
                  const Text(
                    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,
                    overflow: TextOverflow.ellipsis,
                    fontFamily: "Poppins",
                    maxLine: 3,
                    textAlign: TextAlign.start,
                  ),
                ],
              ),
            ),
          ),

用Expanded()包装容器

Expanded (child: 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,
                    ),
                  ),
),
