我有一个名为DataList的可滚动列表,它根据代码进行映射。 index.js中有一个调用,它将更新列表以在DataList中显示更多项。如何修改滚动视图以实现无限滚动,当用户滚动到DataList上的某个点时,该滚动将调用该函数?
const mapStateToPropsDataList = (state) => {
return {
dataListItems: state.resource.dataListItems
}
}
const mapDispatchToPropsDataList = (dispatch) => {
return {
read: ()=>{ resourceRead(); }
}
}
let DataList = ({dataListItems}) => {
var _scrollView: ScrollView;
return (
<View style={styles.dataListBox}>
<View style={styles.dataListWrapper}>
<DataListToolbar/>
<View style={styles.dataListContentBox}>
<View style={styles.dataListContentWrapper}>
<ScrollView ref={(scrollView) => { _scrollView = scrollView; }}
scrollEventThrottle={200}>
<List>
{dataListItems.map((items,index)=>(
<div>
<ListItem>
<div className="listItemBox">
<div className="listItemWrapper">
<div className="listItemImageBox">
<img src={items.image}/>
</div>
<div className="listItemTextBox">
<div className="listItemTextWrapper">
<div className="listItemTextTitleBox">
<div className="listItemTextTitleWrapper">
<span>{items.id}</span>
</div>
</div>
<div className="listItemTextDescriptionBox">
<div className="listItemTextDescriptionWrapper">
<p>{items.name}</p>
</div>
</div>
</div>
</div>
</div>
</div>
</ListItem>
<Divider/>
</div>
))}
</List>
</ScrollView>
</View>
</View>
</View>
</View>
)
}
// modify this code for DataList
DataList = connect(
mapStateToPropsDataList,
mapDispatchToPropsDataList
)(DataList)
