ReactNative ListView

直接上代码

1.普通模式
'use strict';
import React, {
AppRegistry,
Component,
StyleSheet,
Text,
View,
ListView,
} from'react-native';
var ListViewDemo =React.createClass({
getInitialState: function() {
var ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
return {
dataSource: ds.cloneWithRows(['row1', 'row 2','row 3','row 4','row 5','row 6','row 7','row 8']),
};
},
render: function() {
return (
dataSource={this.state.dataSource}
renderRow={(rowData) =>{rowData}}
/>
);
}
});
AppRegistry.registerComponent('ListViewDemo',() => ListViewDemo);

2.增强模式（加图片，加点击监听）

'use strict';
import React, {
AppRegistry,
Component,
StyleSheet,
Text,
View,
ListView,
Image,
TouchableOpacity,
} from'react-native';
var THUMB_URLS = [
require('./imgs/like.png'),
require('./imgs/dislike.png'),
require('./imgs/call.png'),
require('./imgs/fist.png'),
require('./imgs/bandaged.png'),
require('./imgs/flowers.png'),
require('./imgs/heart.png'),
require('./imgs/liking.png'),
require('./imgs/party.png'),
require('./imgs/poke.png'),
require('./imgs/superlike.png'),
require('./imgs/victory.png'),
];
var ListViewDemo =React.createClass({
getInitialState: function() {
var ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
return {
dataSource: ds.cloneWithRows(['row1', 'row 2','row 3','row 4','row 5','row 6','row 7','row 8','row 9','row10','row 11','row 12']),
};
},
_renderRow: function(rowData: string,sectionID: number, rowID: number) {
var imgSource = THUMB_URLS[rowID];
return (





{rowData + '我是测试行号哦~'}




);
},
render: function() {
return (
dataSource={this.state.dataSource}
renderRow={this._renderRow}
/>
);
}
});
var styles =StyleSheet.create({
row: {
flexDirection: 'row',
justifyContent: 'center',
padding: 10,
backgroundColor: '#F6F6F6',
},
thumb: {
width: 50,
height: 50,
},
});
AppRegistry.registerComponent('ListViewDemo',() => ListViewDemo);

3.网格模式的gridview（实际上是用listview改样式）

'use strict';
var React =require('react-native');
var {
AppRegistry,
Image,
ListView,
TouchableHighlight,
StyleSheet,
Text,
View,
} = React;

var THUMB_URLS = [
require('./imgs/like.png'),
require('./imgs/dislike.png'),
require('./imgs/call.png'),
require('./imgs/fist.png'),
require('./imgs/bandaged.png'),
require('./imgs/flowers.png'),
require('./imgs/heart.png'),
require('./imgs/liking.png'),
require('./imgs/party.png'),
require('./imgs/poke.png'),
require('./imgs/superlike.png'),
require('./imgs/victory.png'),
require('./imgs/logo.png'),
];

var ListViewDemo =React.createClass({
getInitialState: function() {
var ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
return {
dataSource:ds.cloneWithRows(this._genRows({})),
};
},
_pressData: ({}: {[key: number]: boolean}),
componentWillMount: function() {
this._pressData = {};
},
render: function() {
return (
initialListSize={12}
contentContainerStyle={styles.list}
dataSource={this.state.dataSource}
renderRow={this._renderRow}
/>
);
},
_renderRow: function(rowData: string,sectionID: number, rowID: number) {
var imgSource = THUMB_URLS[rowID];
return (





{rowData}




);
},
_genRows: function(pressData: {[key: number]:boolean}): Array {
var dataBlob = [];
for (var ii = 0; ii < THUMB_URLS.length;ii++) {
dataBlob.push('单元格 ' + ii);
}
return dataBlob;
},
});
var styles =StyleSheet.create({
list: {
marginTop:5,
justifyContent: 'space-around',
flexDirection: 'row',
flexWrap: 'wrap'
},
row: {
justifyContent: 'center',
padding: 5,
margin: 3,
width: 85,
height: 85,
backgroundColor: '#F6F6F6',
alignItems: 'center',
borderWidth: 1,
borderRadius: 5,
borderColor: '#CCC'
},
thumb: {
width: 45,
height: 45
},
text: {
flex: 1,
marginTop: 5,
fontWeight: 'bold'
},
});
AppRegistry.registerComponent('ListViewDemo',() => ListViewDemo);

listview监听

转致TouchableOpacity专题学习。
该控件主要是负责控件的监听，可以理解为一个module。
