React Native TabNavigator底部导航

1). Navigation 官方文档

2). 安装

yarn add react-navigation
# or with npm
# npm install --save react-navigation

3). 定义页面

• Home.js

import React, {PureComponent} from 'react';
import {
    Button,
    StyleSheet, Text,
    View
} from 'react-native';

/**
 * @FileName: Find
 * @Author: mazaiting
 * @Date: 2018/6/12
 * @Description:
 */
class Home extends PureComponent {
    
    static navigationOptions = {
        title: 'Home'
    };
    
    render() {
        return (
            
                首页
                 {
                        this.props.navigation.navigate('Detail')
                    }}
                />
            
        )
    }
}

/**
 * 样式属性
 */
const styles = StyleSheet.create({
    container: {
        backgroundColor: '#DDD'
    }
});

/**
 * 导出当前Module
 */
module.exports = Home;

• Find.js

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

/**
 * @FileName: Find
 * @Author: mazaiting
 * @Date: 2018/6/12
 * @Description:
 */
class Find extends PureComponent {
    
    static navigationOptions = {
        title: 'Find'
    };
    
    render() {
        return (
            
                发现
            
        )
    }
}

/**
 * 样式属性
 */
const styles = StyleSheet.create({
    container: {
        backgroundColor: '#DDD'
    }
});

/**
 * 导出当前Module
 */
module.exports = Find;

• Detail.js

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

/**
 * @FileName: Mine
 * @Author: mazaiting
 * @Date: 2018/6/12
 * @Description:
 */
class Detail extends PureComponent {
    static navigationOptions = {
        title: 'Detail'
    };
    render() {
        return (
            
                详细页面
            
        )
    }
}

/**
 * 样式属性
 */
const styles = StyleSheet.create({
    container: {
        backgroundColor: '#DDD'
    }
});

/**
 * 导出当前Module
 */
module.exports = Detail;

4). 创建导航栈

/**
 * 主页 栈
 */
const HomeStack = createStackNavigator({
    Home: HomeScreen,
    Detail: DetailScreen,
});

/**
 * 发现栈
 */
const FindStack = createStackNavigator({
    Find: FindScreen,
    Detail: DetailScreen
});

5). 创建底部导航器

import React from 'react';
import {createStackNavigator, createBottomTabNavigator} from 'react-navigation';
import TabBarItem from './TabBarItem';
import HomeScreen from './Home';
import FindScreen from './Find';
import DetailScreen from './Detail';


/**
 * 主页 栈
 */
const HomeStack = createStackNavigator({
    Home: HomeScreen,
    Detail: DetailScreen,
});

/**
 * 发现栈
 */
const FindStack = createStackNavigator({
    Find: FindScreen,
    Detail: DetailScreen
});

/**
 * 底部导航器
 * 官网 https://reactnavigation.org/docs/en/getting-started.html
 */
const BottomTabNavigatorArticle = createBottomTabNavigator(
    {
        Home: HomeStack,
        Find: FindStack
    },
    {
        navigationOptions: ({navigation}) => ({
            tabBarIcon: ({focused, tintColor}) => {
                const {routeName} = navigation.state;
                switch (routeName) {
                    case 'Home':
                        return (
                            
                        );
                    case 'Find':
                        return (
                            
                        );
                }
            },
            tabBarOptions: {
                activeTintColor: 'tomato',
                inactiveTintColor: 'gray'
            }
        })
    }
);

/**
 * 导出当前Module
 */
module.exports = BottomTabNavigatorArticle;

其中TabBarItem.js

import React, {PureComponent} from 'react';
import {
    Image
} from 'react-native';
// npm install --save prop-types
import PropTypes from 'prop-types';

const ImageSourcePropType = require('ImageSourcePropType');

/**
 * @FileName: TabBarItem
 * @Author: mazaiting
 * @Date: 2018/6/12
 * @Description:
 */
class TabBarItem extends PureComponent {
    /**
     * 属性参数
     属性名称： React.PropTypes.array,
     属性名称： React.PropTypes.bool,
     属性名称： React.PropTypes.func,
     属性名称： React.PropTypes.number,
     属性名称： React.PropTypes.object,
     属性名称： React.PropTypes.string,
     */
    static propTypes = {
        focused: PropTypes.bool.isRequired,
        selectedImage: ImageSourcePropType,
        normalImage: ImageSourcePropType
    };
    
    render() {
        const image = this.props.focused ? this.props.selectedImage : this.props.normalImage;
        return (
            
        )
    }
}

/**
 * 导出当前Module
 */
module.exports = TabBarItem;

6). 注册启动

import BottomTabNavigatorArticle from './js/article/tab/BottomTabNavigatorArticle'

// 设置关闭警告提示
global.console.disableYellowBox = true;

AppRegistry.registerComponent('abcd', () => BottomTabNavigatorArticle);

8). 设置导航器标题居中

• Home.js

    static navigationOptions = {
        title: 'Home',
        headerTitleStyle: {
            flex: 1,
            textAlign: 'center',
        }
    };

• Detail.js

    static navigationOptions = {
        title: 'Detail',
        // 如果导航器左边没有控件，则只设置这一句
        headerTitleStyle: {
            flex: 1,
            textAlign: 'center',
        },
        // 如果导航器左侧有控件，则添加这一句
        headerRight: (
            // 该View可替换为其他组件
            
        )
    };
