React Native的组件ListView类似于iOS中的UITableView和UICollectionView,也就是说React Native的组件ListView既可以实现UITableView也可以实现UICollectionView。

ListView的使用方法:

1.首先创建一个ListView.DataSource数据源,然后向他传递一个普通的数据源数组。

2.使用该数据源实例化一个ListView组件,定义一个renderRow回调函数,这个函数会接收数组中的每个数据作为参数,并返回一个可以渲染的组件部分。这个组件部分就是ListView的每一行。

  //设置初始值
getInitialState(){
//设置数据源
var ds = new ListView.DataSource({rowHasChanged:(r1,r2) => r1 !== r2}); //当且仅当cell中的任意两行不相等时才重新渲染
//设置返回数据
return{
dataSource:ds.cloneWithRows(Wine)
}
},
render(){
return(
<ListView
dataSource={this.state.dataSource} //数据源
renderRow={this.renderRow} //返回具体的cell,有四个参数 => 1:一条信息 2:分组ID 3:行ID 4:标记是否高亮选中的状态信息.不带()表示参数自传递
/>
);
},

  演示代码如下:

/**
* Sample React Native App
* https://github.com/facebook/react-native
* 周少停 listView
* 2016-09-21
*/

import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View,
Image,
ListView
} from 'react-native';
//导入json数据
var Wine = require('./WineJson.json'); //json数组

var Project = React.createClass({
//设置初始值
getInitialState(){
//设置数据源
var ds = new ListView.DataSource({rowHasChanged:(r1,r2) => r1 !== r2}); //当且仅当cell中的任意两行不相等时才重新渲染
//设置返回数据
return{
dataSource:ds.cloneWithRows(Wine)
}
},
render(){
return(
<ListView
dataSource={this.state.dataSource} //数据源
renderRow={this.renderRow} //返回具体的cell,有四个参数 => 1:一条信息 2:分组ID 3:行ID 4:标记是否高亮选中的状态信息.不带()表示参数自传递
/>
);
},
//返回具体的cell
renderRow(rowData,sectionID,rowID,highlightRow){
return(
<View style={styles.cellViewStyle}>
{/*左边的图片*/}
<Image source={{uri:rowData.image}} style={styles.leftImageStyle} />
{/*右边的View*/}
<View style={styles.rightViewStyle}>
<Text style={styles.nameTextStyle}>{rowData.name}</Text>
<Text style={styles.montyTextStyle}>${rowData.money}</Text>
</View>
</View>
);
}

});

const styles = StyleSheet.create({
cellViewStyle:{
flexDirection:'row',//主轴方向
borderBottomWidth:1,
borderBottomColor:'cyan'
},
leftImageStyle:{
width:60,
height:60
},
rightViewStyle:{

},
nameTextStyle:{

},
montyTextStyle:{
color:'red',
//距底部2
position:'absolute',
bottom:2
}
});

AppRegistry.registerComponent('Project', () => Project);

涉及到的json数据如下:

[
    {
        "image":"1.png",
        "money":"319",
        "name":"酒名1"

    },
    {

    },
    {

        "name":"酒名15"
    },
    {
        "image":"16.png",
        "money":"369",
        "name":"酒名16"
    },
    {
        "image":"17.png",
        "money":"7397",
        "name":"酒名17"
    },
    {
        "image":"18.png",
        "money":"7397",
        "name":"酒名18"
    },
    {
