你需要自己实施。我已经实现了这个功能。请看看这对你有帮助。
创建tabs.js
import React from 'react';
import {
StyleSheet,
Text,
View,
TouchableOpacity,RefreshControl
} from 'react-native';
import IconTabs from 'react-native-vector-icons/Ionicons';
import NavigationBar from 'react-native-navbar';
import { Container, Header, Title, Button,Icon } from 'native-base';
const Tabs = React.createClass({
tabIcons: [],
propTypes: {
goToPage: React.PropTypes.func,
activeTab: React.PropTypes.number,
tabs: React.PropTypes.array,
},
componentDidMount() {
this._listener = this.props.scrollValue.addListener(this.setAnimationValue);
},
setAnimationValue({ value, }) {
this.tabIcons.forEach((icon, i) => {
const progress = (value - i >= 0 && value - i <= 1) ? value - i : 1;
});
},
render() {
return (
<View>
<View style={[styles.tabs, this.props.style, ]}>
{this.props.tabs.map((tab, i,) => {
return <TouchableOpacity key={tab} onPress={() => this.props.goToPage(i)} style={styles.tab}>
<IconTabs
name={tab}
size={20}
color={this.props.activeTab === i ? 'rgb(255,255,255)' : 'rgb(189, 224, 250)'}
ref={(icon) => { this.tabIcons[i] = icon; }}
/>
<Text style={{fontWeight:'bold', fontSize:10, color:this.props.activeTab === i ? 'rgb(255,255,255)' : 'rgb(189, 224, 250)'}}>{`${this.props.name[i]}`}</Text>
</TouchableOpacity>;
})}
</View>
</View>
);
},
});
const styles = StyleSheet.create({
tab: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
paddingBottom: 10,
},
tabs: {
height: 50,
flexDirection: 'row',
paddingTop: 5,
borderWidth: 0,
borderTopWidth: 0,
borderLeftWidth: 0,
borderRightWidth: 0,
backgroundColor: '#2196F3',
},
});
export default Tabs;
并在您的视图中使用此组件,如下所示。
import React, {Component} from 'react';
import {
StyleSheet,
Text,
View,
ScrollView,Navigator
} from 'react-native';
import ScrollableTabView from 'react-native-scrollable-tab-view';
import Tabs from './tabs';
export default class LeavesTab extends Component{
constructor(props) {
super(props);
}
_navigate(name) {
this.props.navigator.push({
name: name,
passProps: {
name: name
}
})
}
render() {
let Tabname = ["Tab1","Tab2","Tab3","Tab4"];
return (
<ScrollableTabView
initialPage={this.props.index}
renderTabBar={() => <Tabs name={Tabname} navigator={this.props.navigator} showHeader={true} />}
>
<ScrollView tabLabel="md-calendar">
<Requests tabLabel='Requests' navigator={this.props.navigator} />
</ScrollView>
<ScrollView tabLabel="md-checkbox">
<LeaveList tabLabel='Approved' navigator={this.props.navigator} />
</ScrollView>
<ScrollView tabLabel="md-time">
<LeaveList tabLabel='Pending' navigator={this.props.navigator} />
</ScrollView>
<ScrollView tabLabel="md-close-circle">
<LeaveList tabLabel='Rejected' navigator={this.props.navigator} />
</ScrollView>
</ScrollableTabView>
);
}
}
const styles = StyleSheet.create({
});

Santosh's回答是对的,但我找到了一种基于Native Base标签实现此方法的更简洁方法。
渲染标签组件是必要的,就像在Santosh的例子中一样。
但是在组件中,我可以使用React Native&#39; Tabs
组件,而不是使用export default class App extends Component {
render() {
return (
<Container>
<Header>
<Title>Header</Title>
</Header>
<Content>
<Tabs renderTabBar={() => <TabBar />}>
<One tabLabel="video-camera" />
<Two tabLabel="users" />
</Tabs>
</Content>
<Footer>
<FooterTab>
<Button transparent>
<Icon name="ios-call" />
</Button>
</FooterTab>
</Footer>
</Container>
);
}
}
。一个例子:
comPortComboBox.setModel(new javax.swing.DefaultComboBoxModel<>(new String[]
{ "Item 1", "Item 2", "Item 3", "Item 4" }));
修改强> @KumarSanketSahu说,2.0版本正在改变选项卡中图标的能力。我上面的答案是针对0.5.x版本。

使用NativeBase 2.0及更高版本,您可以使用标题属性中的TabHeading标记向标签添加图标。
<Content>
<Tabs>
<Tab heading={<TabHeading><Icon name='settings'/></TabHeading>}>
<Tab heading={<TabHeading><Icon name='home'/></TabHeading>}>
</Tabs>
</Content>
