React Native项目实战之搭建美团个人中心界面

2018-02-06 17:05:37 浏览数 (1)

在很多app应用型APP中，个人中心往往会单独出一个模块，而对于刚入门React Native的朋友来说，怎么去实现一些静态的页面，并且怎么着手实现，怎么分层，怎么去实现这个架构，我想是很基础的（ps，本人新书，《React Native实战经典》定义国庆前后出版，欢迎大家捧场）。 首先，看一下实现的效果：

项目讲解

首先，这是一个纯静态的页面，包括顶部的个人介绍页面，已经下面的一个扩展页面。而下面扩展页面风格基本差不多，我们可以对其做一个简单的封装（MineItemCell.js），为了项目代码维护的方便，我们还可以将这些样式统一一下（text.js）。 text.js文字样式

/**

 * @flow
 */

import React from 'react';
import ReactNative, { StyleSheet, Dimensions, Text ,ReactElement} from 'react-native';

export function HeadingBig({style, ...props}: Object): ReactElement {
    return <Text style={[styles.h0, style]} {...props} />
}

export function Heading1({style, ...props}: Object): ReactElement {
    return <Text style={[styles.h1, style]} {...props} />
}

export function Heading2({style, ...props}: Object): ReactElement {
    return <Text style={[styles.h2, style]} {...props} />
}

export function Paragraph({style, ...props}: Object): ReactElement {
    return <Text style={[styles.p, style]} {...props} />
}

export function Tip({style, ...props}: Object): ReactElement {
    return <Text style={[styles.tip, style]} {...props} />
}

const styles = StyleSheet.create({
    h0: {
        fontSize: 40,
        color: '#06C1AE',
    },
    h1: {
        fontSize: 15,
        fontWeight: 'bold',
        color: '#222222',
    },
    h2: {
        fontSize: 14,
        color: '#222222',
    },
    p: {
        fontSize: 13,
        color: '#777777',
    },
    tip: {
        fontSize: 13,
        color: '#999999'
    }
});

MineItemCell.js

import React, { Component } from 'react';
import { View, Text, StyleSheet, Image, TouchableOpacity } from 'react-native';
import { Heading2, Paragraph } from './widght/Text'
import Separator from './widght/Separator'

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

class MineItemCell extends Component {
    render() {
        let icon = null;
        if (this.props.image) {
            icon = <Image style={styles.icon} source={this.props.image} />
        }
        return (
            <View style={styles.container}>
                <TouchableOpacity>
                    <View style={[styles.content, this.props.style]}>
                        {icon}
                        <Heading2>{this.props.title}</Heading2>
                        <View style={{ flex: 1, backgroundColor: 'blue' }} />
                        <Paragraph style={{ color: '#999999' }}>{this.props.subtitle}</Paragraph>
                        <Image style={styles.arrow} source={require('./image/icon_arrow.png')} />
                    </View>

                    <Separator />
                </TouchableOpacity>
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        backgroundColor: 'white',
    },
    content: {
        height: 44,
        flexDirection: 'row',
        alignItems: 'center',
        paddingLeft: 15,
        paddingRight: 10,
    },
    icon: {
        width: 25,
        height: 25,
        marginRight: 10,
    },
    subtitleContainer: {
        flexDirection: 'row',
        justifyContent: 'flex-end',
        alignItems: 'center',
    },
    arrow: {
        width: 14,
        height: 14,
        marginLeft: 5,
    }
});

export default MineItemCell;

然后到界面的绘制了，首先绘制顶部个人资料部分：

代码语言：javascript复制
renderHeader() {
        return (
            <View style={styles.header}>
                <View style={styles.topContainer}>
                    <TouchableOpacity>
                        <Image style={[styles.icon, {marginRight: 15}]}
                               source={require('./image/icon_navigationItem_message_white.png')}/>
                    </TouchableOpacity>
                    <TouchableOpacity>
                        <Image style={[styles.icon, {marginRight: 10}]}
                               source={require('./image/icon_navigationItem_set_white.png')}/>
                    </TouchableOpacity>
                </View>
                <View style={styles.userContainer}>
                    <Image style={styles.avatar} source={require('./image/avatar.png')}/>
                    <View>
                        <View style={{flexDirection: 'row'}}>
                            <Heading1 style={{color: 'white'}}>code_xzh</Heading1>
                            <Image style={{marginLeft: 4}}
                                   source={require('./image/beauty_technician.png')}/>
                        </View>
                        <Paragraph style={{color: 'white', marginTop: 4}}>个人信息 ></Paragraph>
                    </View>
                </View>
            </View>
        )
    }

接着，我们在绘制下面的部分，由于下面部分我们队每个子视图做了封装，所以，我们可以这么做：通过getDataList()获取所有的值，进而绘制。 renderCells代码：

代码语言：javascript复制
renderCells() {
        let cells = []
        let dataList = this.getDataList()
        for (let i = 0; i < dataList.length; i  ) {
            let sublist = dataList[i]
            for (let j = 0; j < sublist.length; j  ) {
                let data = sublist[j]
                let cell = <MineItemCell image={data.image} title={data.title} subtitle={data.subtitle}
                                         key={data.title}/>
                cells.push(cell)
            }
            cells.push(<SpacingView key={i}/>)
        }

        return (
            <View style={{flex: 1}}>
                {cells}
            </View>
        )
    }

getDataList()代码：

代码语言：javascript复制
getDataList() {
        return (
            [
                [
                    {title: '我的钱包', subtitle: '办信用卡', image: require('./image/icon_mine_wallet.png')},
                    {title: '余额', subtitle: '￥95872385', image: require('./image/icon_mine_balance.png')},
                    {title: '抵用券', subtitle: '63', image: require('./image/icon_mine_voucher.png')},
                    {title: '会员卡', subtitle: '2', image: require('./image/icon_mine_membercard.png')}
                ],
                [
                    {title: '好友去哪', image: require('./image/icon_mine_friends.png')},
                    {title: '我的评价', image: require('./image/icon_mine_comment.png')},
                    {title: '我的收藏', image: require('./image/icon_mine_collection.png')},
                    {title: '会员中心', subtitle: 'v15', image: require('./image/icon_mine_mineorder.png')},
                    {title: '积分商城', subtitle: '好礼已上线', image: require('./image/icon_mine_member.png')}
                ],
                [
                    {title: '客服中心', image: require('./image/icon_mine_service.png')},
                    {title: '关于美团', subtitle: '我要合作', image: require('./image/icon_mine_about.png')}
                ]
            ]
        )
    }
