首页头部界面
- 效果图：其主要分为一个ScrollView和一个圆点指示器的View，和之前我们所制作的轮播图内容有点相似。

示例代码：

import React, { Component } from 'react';
import {
    AppRegistry,
    StyleSheet,
    Text,
    View,
    Image,
    ScrollView,
    ListView,

//屏幕宽度

var Dimensions = require('Dimensions');
var screenW = Dimensions.get('window').width;


export default class TopView extends Component {

            ItemArr.push(
                <View key = {i} style={{width:screenW,height:150,backgroundColor:ColorArr[i]}}>
                    <Text>{i}</Text>
                </View>
            )
        }
        //返回数组
     return ItemArr;

    }

    // 返回圆点
    renderCircleCount(){

        var CirclArr = [];
        //样式
        var style;

        for(var i = 0;i < 2;i++){

            style = (i == this.state.currentPage) ? {color:'orange'} : {color:'gray'};

            CirclArr.push(
                <Text key = {i} style={[{fontSize:25},style]}>•</Text>
            )
        }
    return CirclArr;
    }
     // 每一帧移动结束之后
    ScrollEnd(Scr){
        // 水平方向偏移量
        const OffSetX = Scr.nativeEvent.contentOffset.x;
        // 页码
        PageCount = OffSetX / screenW;

        // 刷新状态机
        this.setState ({

            currentPage : PageCount

        })


    }
}

const styles = StyleSheet.create({
    container: {
        flex: 1,

        backgroundColor: '#F5FCFF',
    },

    circlestyle: {
        flexDirection:'row',
        alignItems:'center',
        justifyContent:'center',
        backgroundColor:'rgba(255,255,90,0.1)'
    },

});

module.exports = TopView;

给TopView中滑动ScrollView设置内容:用ListView组件将所需要的内容模式搭建
- 效果图：

示例代码：

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

//屏幕宽度

var Dimensions = require('Dimensions');
var kWidth = Dimensions.get('window').width;
// 全局常量
const cols = 5
const cellW = Platform.OS == 'ios' ? 70 : 60;
const cellH = 70;
const vMargin = (kWidth - cellW * cols) / (cols + 1);

export default class TopListView extends Component {

    // 数据由外部参数决定
     static defaultProps = {

             dataArr:[],
     }
    // 构造
    constructor(props) {
        super(props);
        var ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
        this.state = {

            dataSource: ds.cloneWithRows(this.props.dataArr)

        }
    }

    render() {
        return (
            <View style={styles.container}>
                <ListView
                    dataSource={this.state.dataSource}
                    renderRow={this.renderRow}
                    contentContainerStyle={styles.contentViewStyle} //ListView内容样式
                    scrollEnabled={false}  //防止内容视图上下滚动
                />



            </View>
        );
    }

    //每一个cell所包含的内容。
    renderRow(rowData){
        return(

           <TouchableOpacity activeOpacity={0.8} onPress={()=>{alert('跳转到'+rowData.title+'界面')}}>
               <View style={styles.cellStyle}>
                   <Image source={{uri:rowData.image}} style={{width:52,height:52}}/>
                   <Text style={styles.titleStyle}>{rowData.title}</Text>
               </View>
           </TouchableOpacity>
        )


    }
}

const styles = StyleSheet.create({

    contentViewStyle: {
        flexDirection:'row',
        flexWrap:'wrap',
        width:kWidth,
        alignItems:'center',
        justifyContent:'center',
    },

    cellStyle: {
        alignItems:'center',
        justifyContent:'center',
        marginTop:10,
        width:cellW,
        height:cellH,
        marginLeft:vMargin,
    },

    titleStyle: {
       color:'gray',
       fontSize:Platform.OS == 'ios' ? 14 : 12,
    },
});

module.exports = TopListView;

TopListView内容样式搭建完成，则需要在TopView中给TopListView赋予数据源

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

//屏幕宽度
var Dimensions = require('Dimensions');
var screenW = Dimensions.get('window').width;


var TopListView = require('./TopListView');

// 导入JSON数据
var TopMenu = require('../../LocalData/TopMenu.json');

export default class TopView extends Component {

    //构造
    constructor(props) {
      super(props);
      this.state = {

          currentPage : 0,  //当前页码
      };
    }
    render() {
        return (
            <View style={styles.container}>
                <View>
                    {/*显示内容部分*/}
                    <ScrollView
                        horizontal={true}
                        pagingEnabled={true}
                        showsHorizontalScrollIndicator={false}
                        //每一帧移动结束
                        onMomentumScrollEnd={(Scr)=>{this.ScrollEnd(Scr)}}

                    >
                        {this.renderScrollViewContent()}
                    </ScrollView>

                    {/*显示圆点指示器部分*/}
                    <View style={styles.circlestyle}>
                        {this.renderCircleCount()}
                    </View>
                </View>

            </View>
        );
    }
    //ScrollView内容
    renderScrollViewContent(){

        var ItemArr = [];

        // 数据
        var DataArr = TopMenu.data;

        for (var i =0; i<DataArr.length;i++){

            ItemArr.push(
                <TopListView key = {i}
                    // 传入dataSource数据
                    dataArr = {DataArr[i]}

                />
            )
        }
        //返回数组
     return ItemArr;

    }

    // 返回圆点
    renderCircleCount(){

        var CirclArr = [];
        //样式
        var style;

        for(var i = 0;i < TopMenu.data.length;i++){

            style = (i == this.state.currentPage) ? {color:'orange'} : {color:'gray'};

            CirclArr.push(
                <Text key = {i} style={[{fontSize:25},style]}>•</Text>
            )
        }
    return CirclArr;
    }
     // 每一帧移动结束之后
    ScrollEnd(Scr){
        // 水平方向偏移量
        const OffSetX = Scr.nativeEvent.contentOffset.x;
        // 页码
        PageCount = OffSetX / screenW;

        // 刷新状态机
        this.setState ({

            currentPage : PageCount

        })


    }
}

const styles = StyleSheet.create({
    container: {
        flex: 1,

        backgroundColor: '#F5FCFF',
    },

    circlestyle: {
        flexDirection:'row',
        alignItems:'center',
        justifyContent:'center',
        backgroundColor:'rgba(255,255,255,0.1)'
    },

});

module.exports = TopView;

首页中间界面
- 界面分析：

Snip20171001_1.png
中间内容界面主要分为左侧名店抢购视图和右侧两个小的特价视图，并且在整个界面中右侧天天特价这两个绿色框的视图，内容模式布局基本一样，所以我们可以将其自定成一个MiddleCommonView组件

示例代码：

import React, { Component } from 'react';
import {
    AppRegistry,
    StyleSheet,
    Text,
    View,
    Image,
    TouchableOpacity,
    AlertIOS,

} from 'react-native';

var Dimensions = require('Dimensions');
var kWidth = Dimensions.get('window').width;

export default class MiddleCommonView extends Component {

    static defaultProps = {

        title:'',        // 标题
        subTitle:'',     // 子标题
        rightIcon:'',    // 右侧图片
        titleColor:''   //  字体颜色
    }



    render() {
        return (
         <TouchableOpacity activeOpacity={0.8} onPress={()=>{alert('跳转到相关界面')}}>
             <View style={styles.container}>
                {/*左边*/}
               <View>
                  <Text style={[{color:this.props.titleColor},styles.titlesStyle]}>{this.props.title}</Text>
                  <Text style={styles.SubTitleStyle}>{this.props.subTitle}</Text>
               </View>
                {/*右边图片*/}
                <Image source={{uri:this.props.rightIcon}} style={styles.iconStyles}/>
            </View>
         </TouchableOpacity>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        backgroundColor: 'white',
        width:kWidth * 0.5 - 1,
        height:59,
        marginBottom:1,
        //改变主轴方向
        flexDirection:'row',
        alignItems:'center',
        justifyContent:'space-around',
    },
    titlesStyle: {
        fontSize:20,
        fontWeight:'bold',
    },
    SubTitleStyle: {
        color:'gray',
    },
    iconStyles: {
        width:64,
        height:44,
    },
});

module.exports = MiddleCommonView;

MiddleCommonView组件的完成，则需要在外部给其数据.


    renderRightView(){

        var RightArr = [];
        // 右侧视图数据
        var RightData = MiddleJSON.dataRight;

        for(var i = 0;i < RightData.length;i++){
            // 拿到每一条数据
            var OneRightData = RightData[i];

            RightArr.push(
                <MiddleCommonView key = {i}

                    title={OneRightData.title}
                    subTitle={OneRightData.subTitle}
                    rightIcon={OneRightData.rightImage}
                    titleColor={OneRightData.titleColor}
                />
            )
        }

        return RightArr;
    }
}

const styles = StyleSheet.create({
    container: {

        marginTop:15,

        flexDirection:'row',

    },

右侧视图的数据已拿到，接下来则需要完成左侧视图的数据以及布局
- 示例代码：

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

var Dimensions = require('Dimensions');
var kWidth = Dimensions.get('window').width;


var MiddleCommonView = require('./MiddleCommonView');

// 导入数据

var MiddleJSON = require('../../LocalData/HomeTopMiddleLeft.json');

export default class HomeMiddleView extends Component {
    render() {
        return (
            <View style={styles.container}>
                {/*左侧视图*/}
                    {this.renderLeftView()}

                {/*右侧视图*/}
                <View>
                    {this.renderRightView()}
                </View>
            </View>
        );
    }

    renderLeftView(){

        //拿到左侧视图数据
        var LeftData = MiddleJSON.dataLeft[0];
        return(
           <TouchableOpacity activeOpacity={0.8} onPress={()=>{alert('跳转界面!!')}}>
            <View style={styles.LeftViewStyle}>
                     <Image source={{uri:LeftData.img1}} style={styles.leftImageStyle}/>
                     <Image source={{uri:LeftData.img2}} style={styles.leftImageStyle}/>
                     <Text style={{color:'gray', fontSize:15,}}>{LeftData.title}</Text>
                <View style={{flexDirection:'row',marginTop:5,}}>
                    <Text style={{color:'blue',marginRight:5}}>{LeftData.price}</Text>
                    <Text style={{color:'orange',backgroundColor:'yellow'}}>{LeftData.sale}</Text>
                </View>
            </View>
           </TouchableOpacity>
        )
    }


    renderRightView(){

        var RightArr = [];
        // 右侧视图数据
        var RightData = MiddleJSON.dataRight;

        for(var i = 0;i < RightData.length;i++){
            // 拿到每一条数据
            var OneRightData = RightData[i];

            RightArr.push(
                <MiddleCommonView key = {i}

                    title={OneRightData.title}
                    subTitle={OneRightData.subTitle}
                    rightIcon={OneRightData.rightImage}
                    titleColor={OneRightData.titleColor}
                />
            )
        }

        return RightArr;
    }
}

const styles = StyleSheet.create({
    container: {

        marginTop:15,

        flexDirection:'row',

    },

    LeftViewStyle: {
        width:kWidth * 0.5 - 1,
        height:119,
        marginRight:1,
        backgroundColor:'white',
        alignItems:'center',
        justifyContent:'center',


    },
    leftImageStyle: {
        width: 100,
        height:30,

        //图片内容模式
        resizeMode:'contain',
    },
});

module.exports = HomeMiddleView;

运行效果图：

MIddleView.gif

中间内容·下半部分·内容
- HomeMiddleBottomView中分为上下两部分内容，首先我们将之前封装好的MiddleCommonView部分先完善，在此处注意右侧图片的URL (http://p0.meituan.net/w.h/groupop/9aa35eed64db45aa33f9e74726c59d938450.png)中的w.h，这是由前端提供图片的宽高给后台，后台再返回相应尺寸的图片给前端。

//导入组件
var MiddleCommonView = require('./MiddleCommonView');

// 导入json数据
var JsonData = require('../../LocalData/XMG_Home_D4.json');


export default class HomeMiddleBottomView extends Component {
    render() {
        return (
            <View style={styles.container}>
                {/*上部分*/}
                <View style={styles.topViewStyle}>

                </View>

            //拿出单条数据
            var OneData = ItemData[i];

            ItemArr.push(
                <MiddleCommonView key ={i}
                     title={OneData.maintitle}
                     subTitle={OneData.deputytitle}

    }

    // 处理图像的尺寸,因为后期的接口需要前端返回一个图片大小才给符合尺寸的图片接口。
    DealWithImageUrl(url){
        //检查url中是否包含'w.h'这两个字符
        if (url.search('w.h') == -1) { // -1 标示没有找到,正常返回

购物中心模块搭建

Snip20171002_2.png
购物中心模块主要分为绿的框的section和下面蓝色框的cell两个部分，因section部分在本界面中需要用到场合较多，所以先封装成一个组件HJCellsSectionView

完成section组件的封装，则进行下面的内容开发，内容部分是一个ScrollView上有几个Item展示，所以先新建一个ShopCenterItem类：class ShopItems extends React.Component，另外注意一点则是detailurl商品详情页面的url上传到购物中心界面 popToShopCenter再由购物中心界面 popToShopCenter上传到首页 popToHomeView
