可以按如下方式设置应用程序的样式 -
当您想要将样式应用到应用程序时,React 原生样式表组件非常方便且简洁。要使用样式表组件,首先将其导入,如下所示 -
import { StyleSheet } from 'react-native';
您可以使用样式表组件创建样式,如下所示 -
const styles = StyleSheet.create({ container: { flex: 1, marginTop: StatusBar.currentHeight || 0, }, item: { margin: 10, padding: 20, marginVertical: 8, marginHorizontal: 16, } });
上面的样式可以在你的代码中使用如下 -
<View style={styles.container}></View>
这里是一个使用样式表来显示 FlatList 组件的示例 -
import React from "react"; import { FlatList , Text, View, StyleSheet, StatusBar } from "react-native"; export default class App extends React.Component { constructor() { super(); this.state = { data: [ { name: "Javascript Frameworks", isTitle: true }, { name: "Angular", isTitle: false }, { name: "ReactJS", isTitle: false }, { name: "VueJS", isTitle: false }, { name: "ReactNative", isTitle: false }, { name: "PHP Frameworks", isTitle: true }, { name: "Laravel", isTitle: false }, { name: "CodeIgniter", isTitle: false }, { name: "CakePHP", isTitle: false }, { name: "Symfony", isTitle: false } ], stickyHeaderIndices: [] }; } renderItem = ({ item }) => { return ( <View style={styles.item}> <Text style={{ fontWeight: (item.isTitle) ? "bold" : "", color: (item.isTitle) ? "red" : "gray"}} > {item.name} </Text> </View> ); }; render() { return ( <View style={styles.container}> <FlatList data={this.state.data} renderItem={this.renderItem} keyExtractor={item => item.name} stickyHeaderIndices={this.state.stickyHeaderIndices} /> </View> ); } } const styles = StyleSheet.create({ container: { flex: 1, marginTop: StatusBar.currentHeight || 0, }, item: { margin: 10, padding: 20, marginVertical: 8, marginHorizontal: 16, } });
您可以使用 style 属性来添加内联样式。然而,这不是最佳实践,因为它可能很难阅读代码。这是一个关于如何在reactnative组件中使用内联样式的工作示例
导出默认应用程序;
import React from 'react'; import { Button, View, Alert } from 'react-native'; const App = () => { return ( <View style={{flex :1, justifyContent: 'center', margin: 15 }}> <Button title="Click Me" color="#9C27B0" onPress={() => Alert.alert('Testing Button for React Native ')} /> </View> ); }
