我有一个带有 3 个选项卡的模式。每个选项卡都有一个列表视图,任何大于 10 行的数据集都无法正常工作。发生的情况是在初始加载时它正确显示。但是,当显示更多行时,它们都是空的。不知道发生了什么。使用最新的 React-Native。如果有帮助,这里有几个屏幕截图。
<View style={{flex:1, height: this.state.visibleHeight - 100, width: this.state.visibleWidth }}>
{
(this.state.isSubdivisions) ? <Subdivisions model={this.props.model.subdivisions}/>
: (this.state.isProspects) ? <LandProspects model={this.props.model.landProspects}/>
: (this.state.isFavorites) ? <Favorites model={this.props.model.favorites}/>
: null}
</View>

class ListLandProspects extends Component {
constructor(props) {
super(props);
const foo = this.props.model.slice(0,10)
const ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2})
this.state = {
dataSource: ds.cloneWithRows(foo),
deviceHeight: Dimensions.get('window').height,
deviceWidth: Dimensions.get('window').width
}
}
componentDidUpdate(prevProps) {
if (this.props.model != prevProps.model)
this._updateLandProspects()
}
_updateLandProspects(){
const clone = this.props.model.slice()
this.setState({
dataSource: this.state.dataSource.cloneWithRows(clone)
})
}
render() {
return (
<Row>
