使用ListView来实现分组表格，总体不难，值得注意的是相关的数据结构。数据结构类似如下：
var db = {
'sectionID-1':{section1 data},
'sectionID-1':rowID1':{row1 data}
'sectionID-1':rowID2':{row2 data}
'sectionID-2':{section1 data},
'sectionID-2':rowID1':{row1 data}
'sectionID-2':rowID2':{row2 data}
}
var sectionIDs = ['sectionID-1','sectionID-2'];
//注意rowIDs是一个二维的数组，与sectionIDs不同
var rowIDs = [['rowID1','rowID2'],['rowID1','rowID2']]
代码如下：
import React, {Component} from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View,
ListView,
Image,
TouchableOpacity
} from 'react-native';
let carData = require('./Car.json').data;
let ListViewDemoC = React.createClass({
getInitialState(){
let getRowData = (dataBlob,sectionID,rowID) => {
return dataBlob[sectionID + ":" + rowID];
};
let getSectionHeaderData = (dataBlob,sectionID) => {
return dataBlob[sectionID];
};
return {
dataSource: new ListView.DataSource({
getRowData:getRowData,
getSectionHeaderData:getSectionHeaderData,
rowHasChanged:(r1,r2) => r1 !== r2,
sectionHeaderHasChanged:(s1,s2) => s1 !== s2
})
}
},
render() {
return (
<ListView dataSource={this.state.dataSource}
renderRow={this.renderRow}
renderSectionHeader={this.renderSectionHeader}
style={styles.listStyle}
/>
);
},
renderRow(rowData){
return (
<View style={styles.cellStyle}>
<Image source={{url:rowData.icon}} style={styles.iconStyle} />
<Text style={styles.nameStyle}>{rowData.name}</Text>
</View>
);
},
renderSectionHeader(sectionData,sectionID){
return (
<View style={styles.headerStyle}>
<Text style={styles.headerTitleStyle}>{sectionData.title}</Text>
</View>
);
},
componentDidMount() {
//数据处理，
var dataBlob = [],sectionIDs = [],rowIDs = [];
for (var i = 0; i < carData.length; i++) {
//1.把组号放入sectionIDs
sectionIDs.push(i);
//2.将组的内容放置到dataBlob中
let item = carData[i];
dataBlob[i] = item ;
//3.取出组中所有的车
let cars = item.cars;
rowIDs[i] = [];//rowIDs是一个二维数组
//4.遍历所有的车数组
for (var j = 0; j < cars.length; j++) {
rowIDs[i].push(j);
dataBlob[i + ":" + j] = cars[j];
}
}
console.log(dataBlob);
//更新ds
this.setState({
dataSource:this.state.dataSource.cloneWithRowsAndSections(dataBlob,sectionIDs,rowIDs)
});
}
});
const styles = StyleSheet.create({
cellStyle: {
flexDirection:'row',
height:90,
borderBottomColor:'#e0e8EF',
borderBottomWidth:1,
alignItems:'center'
},
iconStyle: {
width:70,

listStyle: {
marginTop: 20
},
headerStyle: {

},
headerTitleStyle: {

}
});
AppRegistry.registerComponent('ListViewDemoC', () => ListViewDemoC);
