rn報(bào)錯cannot add a child to parent without a measure function?

在使用flatlist的時(shí)候加載了一個組件，運(yùn)行報(bào)錯如下：

下面是我的代碼：

import React,{Component} from 'react';
import {
    View,
    Text,
    FlatList,
    StyleSheet,
    TouchableHighlight
} from 'react-native';

import ListItem from './../components/ListItem';

export default class Topic extends Component{
    _renderItem(item){
        return (
            <ListItem
                item={item}
            />
        );
    }
    render(){
        return (
            <View>
                <FlatList
                    data={[{key: 'a'}, {key: 'b'}]}
                    renderItem={this._renderItem}
                />
            </View>
        );
    }
}

下面是子組件的代碼：

import React,{Component} from 'react';
import {
    View,
    Text
} from 'react-native';

export default class ListItem extends Component{
    constructor(props){
        super(props);
    }
    render(){
        return (
            <View>
                <View>
                    <Text>xxxxxxxxxxx</Text>
                    <Text>2 小時(shí)前</Text>
                </View>
                <View>
                    <Text>xxxx發(fā)布</Text>
                    <Text>xxxxxx</Text>
                </View>
            </View>
        );
    }
}
