代碼如下, 如何在移動屏幕上顯示各種屬性? 我可以在控制檯上看到打印出來的對象數組,但我無法使用每個對象中包含的屬性來顯示手機屏幕上的信息。在ListView中迭代renderRow中的對象數組,React-Native
import React, { Component } from 'react';
import { AppRegistry, ListView, View, Text } from 'react-native';
import axios from 'axios';
export default class Component5 extends Component {
constructor() {
super();
const ds = new ListView.DataSource({ rowHasChanged: (r1, r2) => r1 !== r2 });
this.state = {
userDataSource: ds,
};
}
componentDidMount() {
this.fetchUsers();
}
fetchUsers() {
axios.get('https://stageapi6.devmn.net/api/v1/forums/threads?topic_id=2418', {
headers: {
'client-id': '********'
}
})
.then(response => this.setState({ userDataSource: this.state.userDataSource.cloneWithRows(response) }));
}
renderRow = (user) => {
console.log(user); // => [Object, Object, Object, Object .........]
return (
<View>
{/* I need a way to iterate the bojects and display the properties inside teh Text tags, the code below doesn't work */}
<Text>{user.thread.num_posts}</Text>
<Text>{user.thread.topic_name}</Text>
<Text>{user.thread.name}</Text>
</View>
);
}
render() {
return (
<ListView
dataSource={this.state.userDataSource}
renderRow={(user) => this.renderRow(user.threads)}
/>
);
}
}
AppRegistry.registerComponent('Component5',() => Component5);

感謝您的幫助,但遺憾的是在控制檯中的錯誤還是一樣'可能未處理無極抑制(ID:0): 無法讀取undefined'的特性「地圖」。但是我可以在用戶中看到迭代,但不能吐出模擬器上的屬性 –
