android - 为什么不响应原生显示我的背景图像？

Question

下面的代码可以很好地编译为react native，并且我在任何编译器中均未收到任何错误，但我的android仿真器仍然为空白，而不是像预期的那样显示背景图像。有人知道为什么吗？
代码:

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

import bgImage from './Images/background.jpg' 

type Props = {};
export default class App extends Component<Props> {
  render() {
    return (
      <View>
      <ImageBackground source={bgImage} style={styles.backgroundContainer}>
      </ImageBackground>
      </View>
    );
  }
}

const styles = StyleSheet.create({
    backgroundContainer: {
    flex: 1,
    width:null, 
    height:null, 
    justifyContent: 'center',
    alignItems: 'center',
  },
});

试试这个

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

type Props = {};
export default class App extends Component<Props> {
  render() {
    return (
      <View>
      <ImageBackground source={require(./Images/background.jpg)} style={styles.backgroundContainer}>
          <Text> Here Background Image </Text>
      </ImageBackground>
      </View>
    );
  }
}

const styles = StyleSheet.create({
    backgroundContainer: {
    flex: 1,
    width:'100%', 
    height:'100%',
  },
});
