您总是使用相同的数据克隆数据源，因此不会出现新的情况。这是一个有效的示例（通过添加新数据
concat）：
var React = require('react-native');var { StyleSheet, View, Image, ListView, } = React;var data = [ { "id": 1, "profile_picture": { "href": "//like1.r.worldssl.net/ui_big/1305634.jpg" } }, { "id": 2, "profile_picture": { "href": "//like1.r.worldssl.net/ui_big/1305634.jpg" } }, { "id": 3, "profile_picture": { "href": "//like1.r.worldssl.net/ui_big/1305634.jpg" } }, { "id": 4, "profile_picture": { "href": "//like1.r.worldssl.net/ui_big/1305634.jpg" } }, { "id": 5, "profile_picture": { "href": "//like1.r.worldssl.net/ui_big/1305634.jpg" } }, { "id": 6, "profile_picture": { "href": "//like1.r.worldssl.net/ui_big/1305634.jpg" } }];var InfiniteScreen = React.createClass({ getInitialState: function () { return { isLoadingTail: false, dataSource: new ListView.DataSource({ rowHasChanged: (row1, row2) => row1 !== row2, }) }; }, componentDidMount: function () { this._data = []; this.setState({ dataSource: this.getDataSource(data) }); }, renderRow: function (item) { return ( <View> <Image style={{width: 80, height: 80}} source={{uri: 'http:' + item.profile_picture.href}}/> </View> ); }, onEndReached: function () { console.log('onEndReached', this.state.isLoadingTail); if (this.state.isLoadingTail) { // We're already fetching return; } this.setState({ isLoadingTail: true }); this.setState({ isLoadingTail: false, dataSource: this.getDataSource(data) }); }, getDataSource: function (users):ListView.DataSource { this._data = this._data.concat(users); return this.state.dataSource.cloneWithRows(this._data); }, render: function () { return ( <View style={styles.container}> <ListView dataSource={this.state.dataSource} renderRow={this.renderRow} onEndReached={this.onEndReached} /> </View>); }});var styles = StyleSheet.create({ container: { flex: 1, justifyContent: 'center', backgroundColor: '#F5FCFF', },});
