如何在材料UI中应用自定义主题

阅读本教程后，我尝试将自定义主题应用于我的React组件

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

我将主题写在这样的单独的javascript文件中

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,
  }
};

我按照以下方式将此主题应用于我的组件

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，当控件呈现时，它应具有“ deepPurpleA700”颜色..但是控件文本始终为黑色。所以我的主题不适用。
