React Native在<Text>字段中为单个单词添加粗体或斜体

Question

如何在文本字段中以粗体或斜体显示单个单词？有点像这样:

<Text>This is a sentence <b>with</b> one word in bold</Text>

如果我为粗体字符创建一个新的文本字段,它会将它分成另一行,这样肯定不是这样做的.这就像在<p>标签中创建<p>标签只是为了使一个单词变为粗体.

Answer 1

您可以<Text>像其他文本组件一样使用容器.这是一个例子:

...
<Text>
  <Text>This is a sentence</Text>
  <Text style={{fontWeight: "bold"}}> with</Text>
  <Text> one word in bold</Text>
</Text>
...

这是一个例子.

Answer 2

为了更像网络的感觉:

const B = (props) => <Text style={{fontWeight: 'bold'}}>{props.children}</Text>

<Text>I am in <B>bold</B> yo.</Text>

Answer 3

您还可以将一个文本标签放在另一个文本标签内。第二个文本标记将继承第一个文本标记的样式，但您仍可以独立于其父级对其进行样式设置。

<Text style={styles.bold}>Level: 
    <Text style={styles.normal}>Easy</Text>
</Text>

//in your stylesheet...

  bold: {
    fontSize: 25,
    fontWeight: "bold",
    color: "blue",
  },
  normal: {
  // will inherit size and color attributes
    fontWeight: "normal",
  }

你可以使用https://www.npmjs.com/package/react-native-parsed-text

import ParsedText from 'react-native-parsed-text';
 
class Example extends React.Component {
  static displayName = 'Example';
 
  handleUrlPress(url) {
    LinkingIOS.openURL(url);
  }
 
  handlePhonePress(phone) {
    AlertIOS.alert(`${phone} has been pressed!`);
  }
 
  handleNamePress(name) {
    AlertIOS.alert(`Hello ${name}`);
  }
 
  handleEmailPress(email) {
    AlertIOS.alert(`send email to ${email}`);
  }
 
  renderText(matchingString, matches) {
    // matches => ["[@michel:5455345]", "@michel", "5455345"]
    let pattern = /\[(@[^:]+):([^\]]+)\]/i;
    let match = matchingString.match(pattern);
    return `^^${match[1]}^^`;
  }
 
  render() {
    return (
      <View style={styles.container}>
        <ParsedText
          style={styles.text}
          parse={
            [
              {type: 'url',                       style: styles.url, onPress: this.handleUrlPress},
              {type: 'phone',                     style: styles.phone, onPress: this.handlePhonePress},
              {type: 'email',                     style: styles.email, onPress: this.handleEmailPress},
              {pattern: /Bob|David/,              style: styles.name, onPress: this.handleNamePress},
              {pattern: /\[(@[^:]+):([^\]]+)\]/i, style: styles.username, onPress: this.handleNamePress, renderText: this.renderText},
              {pattern: /42/,                     style: styles.magicNumber},
              {pattern: /#(\w+)/,                 style: styles.hashTag},
            ]
          }
          childrenProps={{allowFontScaling: false}}
        >
          Hello this is an example of the ParsedText, links like http://www.google.com or http://www.facebook.com are clickable and phone number 444-555-6666 can call too.
          But you can also do more with this package, for example Bob will change style and David too. foo@gmail.com
          And the magic number is 42!
          #react #react-native
        </ParsedText>
      </View>
    );
  }
}
 
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
 
  url: {
    color: 'red',
    textDecorationLine: 'underline',
  },
 
  email: {
    textDecorationLine: 'underline',
  },
 
  text: {
    color: 'black',
    fontSize: 15,
  },
 
  phone: {
    color: 'blue',
    textDecorationLine: 'underline',
  },
 
  name: {
    color: 'red',
  },
 
  username: {
    color: 'green',
    fontWeight: 'bold'
  },
 
  magicNumber: {
    fontSize: 42,
    color: 'pink',
  },
 
  hashTag: {
    fontStyle: 'italic',
  },
 
});

Answer 5

它不在询问的文本字段中，但将单独的文本元素包装到视图中会提供所需的输出。如果您不想将另一个库添加到您的项目中只是为了设置一些文本的样式，则可以使用它。

<View style={{flexDirection: 'row'}}>
 <Text style={{fontWeight: '700', marginRight: 5}}>Contact Type:</Text>
 <Text>{data.type}</Text>
</View>

结果如下

Answer 6

使用此React本机库

安装

npm install react-native-htmlview --save

基本用法

 import React from 'react';
 import HTMLView from 'react-native-htmlview';

  class App extends React.Component {
  render() {
   const htmlContent = 'This is a sentence <b>with</b> one word in bold';

  return (
   <HTMLView
     value={htmlContent}
   />    );
  }
}

支持几乎所有的html标签。

对于更高级的用法，例如

1. 链接处理
2. 自定义元素渲染
