react native中使用ScrollableTabView

第一步，下载依赖

npm install react-native-scrollable-tab-view --save

第二步，引入

import ScrollableTabView, { ScrollableTabBar, DefaultTabBar } from 'react-native-scrollable-tab-view';

第三步，使用

class TabTopView extends Component {
    render() {
        return (
            <ScrollableTabView
                style={styles.container}
                renderTabBar={() => <DefaultTabBar />}
                tabBarUnderlineStyle={styles.lineStyle}
                tabBarActiveTextColor='#FF0000'>

                <Text style={styles.textStyle} tabLabel='娱乐'>娱乐</Text>
                <Text style={styles.textStyle} tabLabel='科技'>科技</Text>
                <Text style={styles.textStyle} tabLabel='军事'>军事</Text>
                <Text style={styles.textStyle} tabLabel='体育'>体育</Text>
            </ScrollableTabView>
        );
    }

由于我把里面的一层提出来循环了，所以在上面使用方法的时候直接找了另一种方法

效果图是

完整代码是 home.js
