ScrollView : 滾動視圖. 它內(nèi)部的子元素不論當前有沒有顯示都會被渲染.如果想只渲染當前顯示的,使用listview替代

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

class IScrolledDownAndWhatHappenedNextShockedMe extends Component {
  render() {
      return(
        <ScrollView> {/*圖片與文字混排*/}
          <Text style={{fontSize:96}}>Scroll me plz</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>If you like</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>Scrolling down</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />

          <Text style={{fontSize:80}}>React Native</Text>
        </ScrollView>
    );
  }
}


AppRegistry.registerComponent(
