我目前正在使用React Native和新的反應導航。在那裏,我正在努力跟隨tutorial for nesting navigators,但總有一個錯誤:使用反應導航器嵌套導航器 - 'Home'應聲明屏幕
Route 'Home' should declare a screen. For example:
import MyScreen from './MyScreen';
...
Home: {
screen: MyScreen,
}
我不知道我在做什麼錯。當我單獨啓動導航器時,他們會工作。但不幸的是沒有合併。
這是App.js,這是我使用教程創建:
import React from 'react';
import {
AppRegistry,
Text,
View,
Button
} from 'react-native';
import {
StackNavigator,
TabNavigator
} from 'react-navigation';
class HomeScreen extends React.Component {
static navigationOptions = {
title: 'Welcome',
};
render() {
const { navigate } = this.props.navigation;
return <View>
<Text>Hello!</Text>
<Button
onPress={() => this.props.navigation.navigate('Chat', { user: 'Daniel' })}
title="ReactNavigation Test"
/>
</View>;
}
}
class ChatScreen extends React.Component {
static navigationOptions = {
title: 'ReactNavigation Test',
};
render() {
const { params } = this.props.navigation.state;
return (
<View>
<Text>Neue Seite für den Navigator. Hallo {params.user}!</Text>
</View>
);
}
}
class RecentChatsScreen extends React.Component {
render() {
return <Text>List of recent chats</Text>
}
}
class AllContactsScreen extends React.Component {
render() {
return <Text>List of all contacts</Text>
}
}
const ReactNativeTest = StackNavigator({
Home: { screen: MainScreenNavigator },
Chat: { screen: ChatScreen },
});
const MainScreenNavigator = TabNavigator({
Recent: { screen: RecentChatsScreen },
All: { screen: AllContactsScreen },
});
AppRegistry.registerComponent('ReactNativeTest',() => ReactNativeTest);
也許你能幫助我在那裏。我問了同樣的問題here,但也許這是更好的問題。
在此先感謝!
當然,我怎麼能忽略這個。非常感謝! – Daniel
謝謝,我也犯了同樣的錯誤! –
哎呀!沒有吊起來!我在想,因爲它是JS,無論我在哪裏定義它,它都會解決這個變量。 –
