自己改了下，效果还可以，不用改页面结构，参考上面贴的stackoverflow的帖子
修改 layouts/TopicList.js

constructor(props) {
super(props);
var ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
this.state = {
isLoadingTail: false,
ds: ds.cloneWithRows(props.data)
};
this.shouldComponentUpdate = PureRenderMixin.shouldComponentUpdate.bind(this);
}
getSCData() {
const {tab, limit, page, actions, data} = this.props;
if (data.length) {
actions.getTopicsByTab(tab, {
page: page + 1,
limit
});
this.setState({
isLoadingTail: false
});
}
}
_onEndReached() {
if (this.state.isLoadingTail) {
return;
}
this.setState({
isLoadingTail: true,
dataSource: this.getSCData()
});
console.log('onEndReached', this.state.isLoadingTail);
}
