我创建了一个虚拟项目来学习。因此,我使用按钮创建了一个虚拟的登录页面,该页面将我重定向到主应用程序,它是bottomTabs应用程序。 登录屏幕上显示topBar,但是当我单击要重定向的按钮时,即使定义了topBar也看不到任何东西。
这是我的App.js
import { Navigation } from 'react-native-navigation';
import AuthScreen from './src/screens/Auth/Auth';
import FindPlaceScreen from './src/screens/FindPlace/FindPlace';
import SharePlaceScreen from './src/screens/SharePlace/SharePlace';
// Register screens
Navigation.registerComponent("awesome-places.AuthScreen", () => AuthScreen);
Navigation.registerComponent("awesome-places.SharePlaceScreen", () => SharePlaceScreen);
Navigation.registerComponent("awesome-places.FindPlaceScreen", () => FindPlaceScreen);
// Start the app
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setRoot({
root: {
stack: {
children: [
{
component: {
name: 'awesome-places.AuthScreen',
options: {
topBar: {
title: {
text: 'Título'
}
}
}
}
}
],
}
}
});
});
我的AuthScreen组件就是这个组件:
import React, {Component} from 'react';
import { Button, View, Text, StyleSheet } from 'react-native';
import startMainTabs from './../MainTabs/startMainTabs';
export default class AuthScreen extends Component {
loginHandler = () => {
startMainTabs();
}
render() {
return (
<View style={styles.container}>
<Text>AuthScreen</Text>
<Button title="Login" onPress={this.loginHandler}/>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
margin: 25
}
});
主要标签代码为:
import { Navigation } from 'react-native-navigation';
import Icon from 'react-native-vector-icons/Ionicons';
const startTabs = () => {
Promise.all([
Icon.getImageSource('md-map', 30),
Icon.getImageSource('ios-share-alt', 30)
]).then((res) => {
Navigation.setRoot({
root: {
bottomTabs: {
children: [
{
component: {
name: 'awesome-places.SharePlaceScreen',
options: {
topBar: {
visible: true,
title: {
text: 'Título'
}
},
bottomTab: {
fontSize: 12,
text: 'A',
icon: res[0],
}
}
},
},
{
component: {
name: 'awesome-places.FindPlaceScreen',
options: {
topBar: {
visible: true,
title: {
text: 'Título'
}
},
bottomTab: {
fontSize: 12,
text: 'B',
icon: res[1],
}
}
},
},
],
},
}
});
})
}
export default startTabs;
如果有此帮助,我正在调用的组件完全相同,并且代码如下:
import React, {Component} from 'react';
import { View, Text, StyleSheet } from 'react-native';
export default class FindPlaceScreen extends Component {
render() {
return (
<View style={styles.container}>
<Text>Find Place</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
margin: 25
}
});
我当前使用的环境是:
答案 0 :(得分:0)
我将stratMainTabs文件修改为:
import { Navigation } from 'react-native-navigation';
import Icon from 'react-native-vector-icons/Ionicons';
const startTabs = () => {
Promise.all([
Icon.getImageSource('md-map', 30),
Icon.getImageSource('ios-share-alt', 30)
]).then((res) => {
Navigation.setRoot({
root: {
bottomTabs: {
children: [
{
stack: {
children: [
{
component: {
name: 'awesome-places.SharePlaceScreen',
options: {
topBar: {
animate: false,
visible: true,
title: {
text: 'Título A'
}
},
bottomTab: {
fontSize: 12,
text: 'A',
icon: res[0],
}
}
},
}
]
}
},
{
stack: {
children: [
{
component: {
name: 'awesome-places.FindPlaceScreen',
options: {
topBar: {
animate: false,
visible: true,
title: {
text: 'Título B'
}
},
bottomTab: {
fontSize: 12,
text: 'B',
icon: res[1],
}
}
},
}
]
}
},
],
},
}
});
})
}
export default startTabs;
基本上,我将子元素放入堆栈中,并在其中添加了tabComponent。 这就解决了问题。有人可以分享为什么这行得通吗?
