[Wondgirl]从零开始学React Native之View(四)

index.ios.js如下:

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

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

export default class demo extends Component {
  render() {
    return (
      <View style={styles.container}>
          <View style={[styles.item,styles.center]}>
             <Text style={styles.font}>机票</Text>
          </View>
          <View style={[styles.item,styles.lineLeftRight]}>
              <View style={[styles.center,{flex:},styles.lineCenter]}>
                   <Text style={styles.font}>火车票</Text>

              </View>
              <View style={[styles.center,{flex:}]}>
                   <Text style={styles.font}>接送机</Text>
              </View>
          </View>
          <View style={[styles.item,styles.lineLeftRight]}>
              <View style={[styles.center,{flex:},styles.lineCenter]}>
                   <Text style={styles.font}>汽车票</Text>

              </View>
              <View style={[styles.center,{flex:}]}>
                   <Text style={styles.font}>用车</Text>
              </View>
          </View>
      </View>
    );
  }
}

//样式
const styles = StyleSheet.create({
  item:{
      flex:,
      height:,
      borderColor:'blue',
      borderWidth:,
      backgroundColor:'#ff0067'
  },
  container: {
    borderWidth:,
    borderColor:'red',
    flexDirection:'row',
    marginTop:,
    marginLeft:,
    marginRight:
  },
  font:{
    color:'#fff',
    fontSize:,
    fontWeight:'bold'
  },
  center:{
    justifyContent:'center',
    alignItems:'center'

  },
  lineCenter:{
    borderBottomWidth:/PixelRatio.get(),
    borderColor:'#fff'

  },
  lineLeftRight:{
    borderLeftWidth:/PixelRatio.get(),
    borderRightWidth:/PixelRatio.get(),
    borderColor:'#fff'
  }
});

AppRegistry.registerComponent('demo', () => demo);
