问题描述

如何自定义TextField的width和height?

推荐答案

要调整宽度，可以用Container小部件包装TextField，如下所示:

To adjust the width, you could wrap your TextField with a Container widget, like so:

Container(              
  width: 100.0,
  child: TextField()
)

我不太确定要达到TextField高度时需要做什么，但是您绝对可以看看TextStyle小部件，您可以使用它来操纵fontSize和/或height

I'm not really sure what you're after when it comes to the height of the TextField but you could definitely have a look at the TextStyle widget, with which you can manipulate the fontSize and/or height

Container(              
  width: 100.0,
  child: TextField(                                 
    style: TextStyle(
      fontSize: 40.0,
      height: 2.0,
      color: Colors.black                  
    )
  )
)

请记住，根据属性本身的注释，TextStyle中的height是字体大小的倍数:

Bear in mind that the height in the TextStyle is a multiplier of the font size, as per comments on the property itself:

此文本跨度的高度，为字体大小的倍数.

The height of this text span, as a multiple of the font size.

当[height]为null或省略时，将确定行高 直接由字体指标决定，这可能与fontSize不同. 如果[height]不为空，则文本范围的行高将为 [fontSize]的倍数，精确为fontSize * height逻辑像素 高

When [height] is null or omitted, the line height will be determined by the font's metrics directly, which may differ from the fontSize. When [height] is non-null, the line height of the span of text will be a multiple of [fontSize] and be exactly fontSize * height logical pixels tall.

最后但并非最不重要的一点，您可能想看看一下TextField的decoration属性，这为您提供了很多可能性

Last but not least, you might want to have a look at the decoration property of you TextField, which gives you a lot of possibilities

:如何更改TextField

您可以使用TextField的InputDecoration和decoration属性.例如，您可以执行以下操作:

You could play around with the InputDecoration and the decoration property of the TextField. For instance, you could do something like this:

TextField(                                
    decoration: const InputDecoration(
        contentPadding: const EdgeInsets.symmetric(vertical: 40.0),
    )
)
