react-navigation Navigation使用

效果：

首先，在项目目录下，安装react-navigation库：

npm install --save react-navigation

具体代码实现：

index.android.js:

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import {
  AppRegistry,
} from 'react-native';
import rootApp from './js/rootApp'
AppRegistry.registerComponent('GankProject', () => rootApp);

rootAp.js:

/**
 * Created by Administrator on 2017/3/31 0031.
 */
'use strict'
import React from 'react';
import {
    AppRegistry,
    Text,View,Button,
} from 'react-native';
import { StackNavigator } from 'react-navigation';
import ChatScreen from './ChatScreen';
class HomeScreen extends React.Component {
    static navigationOptions = {
        title: 'Welcome',//设置标题内容
    };

    render() {
        const { navigate } = this.props.navigation;
        return (
            
                Hello, Navigation!
                 navigate('Chat',{user:'Lucy'})}
                    title="Chat with Lucy"/>
            
        );
    }
}

const SimpleApp = StackNavigator({
    Home: {screen: HomeScreen},
    Chat:{screen:ChatScreen},

});

export default SimpleApp;

navigate('Chat',{user:'Lucy'})} 意思说：跳转到Chat指的组件，并且带过去的参数key是user,value是Lucy。

ChatScreen.js:

/**
 * Created by Administrator on 2017/3/31 0031.
 */
'use strict'
import React,{Component} from 'react';
import {View,Text} from 'react-native';
class ChatScreen extends Component{
    static navigationOptions = {
        title:'Chat with Lucy',
    };
    render(){
        const {params} = this.props.navigation.state;
        return(
            

                Chat with {params.user}
            
        );
    }
}
export default ChatScreen;

{params.user}意思是接收前面传过来的值，user是前面的key。
