如何将样式传递给 React-Native 中的容器组件 [英] How can you pass styles through to a container component in React-Native

问题描述

我正在尝试为具有默认样式的 React-Native 应用程序创建一些可重用的 UI 组件.

I'm trying to create some reusable UI components for my React-Native app that have default styles.

示例默认 MyText(橙色、14、粗体):

An example default MyText (orange, 14, bold):

import React, { Component, StyleSheet, Text } from 'react-native';

const styles = StyleSheet.create({text: {color: 'orange', fontSize: 14, fontWeight: 'bold'}});

export default class MyText extends Component {
    render() {
        return <Text style={styles.text}>{this.props.children}</Text>
    }
}

我想如何使用它:

import Text from '../ui/myText';

... 
<Text style={{color: 'black'}}>My custom styled text, but in black instead of orange</Text>
...

有没有办法做到这一点?显然，如果我尝试访问 this.props.style 它只会返回一个已编译样式表的 ID.

Is there a way to do this? Obviously if I try to access this.props.style it just returns an ID for a compiled stylesheet.

推荐答案

我在浏览 React-Native-Router-Flux 的源代码时找到了一种方法.

I found a way to do it while browsing through the source code for React-Native-Router-Flux.

样式表可以作为数组传入，看起来 React-Native 是按照从左到右的顺序应用它们的(允许你覆盖特定的属性).

Stylesheets can be passed in as an array, and it looks like React-Native applies them in order from left to right (allowing you to overwrite specific properties).

更新后的 MyText 组件如下所示:

Here is what the updated MyText component should look like:

import React, { Component, StyleSheet, Text } from 'react-native';

const styles = StyleSheet.create({text: {color: 'orange', fontSize: 14, fontWeight: 'bold'}});

export default class MyText extends Component {
    render() {
        return <Text style={[styles.text, this.props.style]}>{this.props.children}</Text>
    }
}
