我在我的React Native应用中实施React Navigation,并想要改变标题栏的背景和前景颜色。我有以下代码:
/**
* Sample React Native App
* https://github.com/facebook/react-native
* @flow
*/
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View
} from 'react-native';
import { StackNavigator } from 'react-navigation';
export default class ReactNativePlayground extends Component {
static navigationOptions = {
title: 'Welcome',
};
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
<Text style={styles.instructions}>
To get started, edit index.android.js
</Text>
<Text style={styles.instructions}>
Double tap R on your keyboard to reload,{'\n'}
Shake or press menu button for dev menu
</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
const SimpleApp = StackNavigator({
Home: { screen: ReactNativePlayground }
});
AppRegistry.registerComponent('ReactNativePlayground', () => SimpleApp);
默认情况下,标题的背景颜色是白色,前景色是黑色。我也查看了React Navigation的文档,但找不到设置样式的地方。有什么帮助吗?
