1、首先安装好ReactNative的运行环境，安装组件依赖库

使用npm install react-native-tab-navigator --save安装所依赖的第三方库

2、导入

import TabNavigator from 'react-native-tab-navigator';

3、使用

               <TabNavigator>
                    <TabNavigator.Item
                        selected={this.state.selectedTab === 'home'}
                        title="业务服务"
                        selectedTitleStyle={{color:"#007aff"}}//设置tab标题颜色
                        renderIcon={() => <Image style={styles.icon} source={require('./res/image/fw1.png')} />}
                        renderSelectedIcon={() => <Image style={[styles.icon,{tintColor:'#007aff'}]} source={require('./res/image/fw2.png')} />}//设置图标选中颜色
                        // badgeText="1"
                        onPress={() => this.setState({ selectedTab: 'home' })}>
                        <View style={styles.pages1}>
                            <Text>这是首页</Text>
                        </View>
                    </TabNavigator.Item>
                    <TabNavigator.Item
                        selected={this.state.selectedTab === 'shebei'}
                        title="设备列表"
                        selectedTitleStyle={{color:"#007aff"}}
                        badgeText="1"
                        renderIcon={() => <Image style={styles.icon} source={require('./res/image/lb1.png')} />}
                        renderSelectedIcon={() => <Image style={[styles.icon,{tintColor:'#007aff'}]} source={require('./res/image/lb2.png')} />}
                        // renderBadge={() => <CustomBadgeView />}
                        onPress={() => this.setState({ selectedTab: 'shebei' })}>
                        <View style={styles.pages2}>
                            <Text>设备列表</Text>
                        </View>
                    </TabNavigator.Item>
                    <TabNavigator.Item
                        selected={this.state.selectedTab === 'hetong'}
                        title="合同管理"
                        selectedTitleStyle={{color:"#007aff"}}
                        renderIcon={() => <Image style={styles.icon} source={require('./res/image/ht1.png')} />}
                        renderSelectedIcon={() => <Image style={[styles.icon,{tintColor:'#007aff'}]} source={require('./res/image/ht2.png')} />}
                        // renderBadge={() => <CustomBadgeView />}
                        onPress={() => this.setState({ selectedTab: 'hetong' })}>
                        <View style={styles.pages3}>
                            <Text>合同管理</Text>
                        </View>
                    </TabNavigator.Item>
                    <TabNavigator.Item
                        selected={this.state.selectedTab === 'qiye'}
                        title="企业信息"
                        selectedTitleStyle={{color:"#007aff"}}
                        renderIcon={() => <Image style={styles.icon} source={require('./res/image/qy1.png')} />}
                        renderSelectedIcon={() => <Image style={[styles.icon,{tintColor:'#007aff'}]} source={require('./res/image/qy2.png')} />}
                        // renderBadge={() => <CustomBadgeView />}
                        onPress={() => this.setState({ selectedTab: 'qiye' })}>
                        <View style={styles.pages4}>
                            <Text>个人中心</Text>
                        </View>
                    </TabNavigator.Item>
                </TabNavigator>

还需要在构造方法中初始化数据，默认让第一个tab选中

    constructor(props) {
        super(props);
        this.state = {selectedTab: "home"}
    }

4、运行结果
