如何在 material ui 中应用自定义主题

Question

阅读本教程后，我正在尝试将自定义主题应用于我的 React 组件

http://www.material-ui.com/#/customization/themes

我把我的主题写在一个单独的 javascript 文件中，就像这样

import Colors from 'material-ui/lib/styles/colors';
import ColorManipulator from 'material-ui/lib/utils/color-manipulator';
import Spacing from 'material-ui/lib/styles/spacing';
import zIndex from 'material-ui/lib/styles/zIndex';

export default {
  spacing: Spacing,
  zIndex: zIndex,
  fontFamily: 'Roboto, sans-serif',
  palette: {
    primary1Color: Colors.cyan500,
    primary2Color: Colors.cyan700,
    primary3Color: Colors.lightBlack,
    accent1Color: Colors.pinkA200,
    accent2Color: Colors.grey100,
    accent3Color: Colors.grey500,
    textColor: Colors.deepPurpleA700,
    alternateTextColor: Colors.white,
    canvasColor: Colors.white,
    borderColor: Colors.grey300,
    disabledColor: ColorManipulator.fade(Colors.darkBlack, 0.3),
    pickerHeaderColor: Colors.cyan500,
  }
};

我按照以下方式将这个主题应用到我的组件中

import React from 'react';
import mui from 'material-ui';
import injectTapEventPlugin from 'react-tap-event-plugin';
import ThemeManager from 'material-ui/lib/styles/theme-manager';
import Colors from 'material-ui/lib/styles/colors';
import MyTheme from './theme.js';

injectTapEventPlugin();

class App extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            messages : [{id: 1, text: 'Hi'}, {id: 2, text: 'Hello'}]
        };
    }

    getChildContext() {
        return {
            muiTheme: ThemeManager.getMuiTheme(MyTheme)
        };
    }

    componentWillMount() {
        let newMuiTheme = this.state.muiTheme;
        this.setState({
            muiTheme: newMuiTheme,
        });     
    }

    render() {

        var messageNodes = this.state.messages.map((message) => {
            return (<div key={message.id}>{message.text}</div>);
        });
        return (<div>{messageNodes}</div>);
    }
}

App.childContextTypes = {
    muiTheme: React.PropTypes.object
};

export default App;

根据我的主题，当我的控件呈现时它应该具有 "deepPurpleA700" 颜色....但我的控件文本始终为黑色。所以我的主题没有应用。

我很确定你需要

static childContextTypes = {
  muiTheme: React.PropTypes.object,
};

在你

之前

getChildContext()

方法。完成后，您应该能够从中删除任何与主题相关的内容 componentWillMount()

现在，这不适用于基本文本。但我可以确认正在应用主题。我通过添加一个 appBar 组件并更改 theme.js 文件中的颜色来测试它。我还添加了一个带有 ListItems 的列表，该文本样式正是您要找的。

这是您修改后的 App.jsx 文件 gist 的 link。

另外，作为旁注，你 server.js 你在第 5 行有一个小错字，你应该

new webpackDevServer(webpack(config), {

没有

new WebpackDevServer(webpack(config), {

Answer 2

您应该首先从 'material-ui/styles/colors' 中导入您的颜色然后像这样在调色板对象中使用它们：

import React, { Component } from 'react';
import {render} from 'react-dom';
import {indigo500, indigo700, redA200} from 'material-ui/styles/colors';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import injectTapEventPlugin from 'react-tap-event-plugin';
injectTapEventPlugin();

import Main from './Main';

const muiTheme = getMuiTheme({
    palette: {
        primary1Color: indigo500,
        primary2Color: indigo700,
        accent1Color: redA200,
        pickerHeaderColor: indigo500,
    },
});

class App extends Component {
    render() {
        return (
            <div>
                <MuiThemeProvider muiTheme={muiTheme}>
                    <Main />
                </MuiThemeProvider>
            </div>
        );
    }
}

render(<App/>, document.getElementById('app')); //you should be having a div with an id of app in your index.html file

并且 Main.js 文件是

import React, { Component } from 'react';
import FloatingActionButton from 'material-ui/FloatingActionButton';


export default class Main extends Component {
    render() {
        return (
            <div>
                <AppBar title="Title"/>
                <FloatingActionButton secondary={true} />
            </div>
        );
    }
}

对我来说，它适用于：

import React, {Component} from 'react';
import {createMuiTheme} from '@material-ui/core/styles';
import MuiThemeProvider from '@material-ui/core/styles/MuiThemeProvider';

const theme = createMuiTheme({
    palette: {
        primary: {
            main: '#0b5994',
        },
        secondary: {
            main: '#1d83c6',
        },
    },
});

class App extends Component {

    render() {
        return (
            <div className="App">
                <MuiThemeProvider theme={theme}>
                    /* content here! */
                </MuiThemeProvider>
            </div>
        );
    }
}

export default App;
