循环一个文章列表

实现一个循环列表
第一步代码如下

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

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


class Email extends Component {
  render(){
    return(
      <View style={styles.container}>
        <Text style={styles.text}>{this.props.name}</Text>
        <Text style={styles.text}>{this.props.url}</Text>
      </View>
      )
  }
}

export default class App extends Component{
  render(){
    return(
      <Email name="框架研发部" url="www.baidu.com"/>
    )
  }
}


var styles=StyleSheet.create({
 container:{
   flex:1,
   paddingTop:40,
 },
 text:{
   color:'red'
 }
})

效果如下

第二步加入数据层
代码为：

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

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

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 *
 * @format
 * @flow
 */
class Email extends React.Component {
  render(){
    return(
      <View style={styles.container}>
        <Text style={styles.text,styles.title}>{this.props.title}</Text>
        <Text style={styles.text}>{this.props.author}</Text>
        <Text style={styles.text}>{this.props.time}</Text>
      </View>
      )
  }
}

export default class App extends React.Component{
  render(){
        var articles = [
        {
            title: "React-Native入门指南",
            author: "vczero",
            time: "2015-06-28"
        },
        {
            title: "为什么世界不一样",
            author: "vczero",
            time: "2015-06-8"
        },
        {
            title: "你来，我就告诉你",
            author: "vczero",
            time: "2015-04-01"
        }
    ];
    return(
      <ScrollView>
        {
          articles.map(function(article){
            return <Email title={article.title} author={article.author} time={article.time}/>
        })
        }
      </ScrollView>
    )
  }
}


var styles=StyleSheet.create({
 container:{
   flex:1,
   paddingTop:20,
   flexDirection:'row'
 },
 text:{
   color:'red'
 },
 title:{
   color:'blue'
 }
})
 

效果如下
