Amo*_*pta 4 reactjs react-native react-hooks
所以我有一个 react-native flat 列表,我在每个列表中使用钩子FlatList renderItem,像这样,
export const RenderEntityList = (props) => {
const { entityList } = props;
const getEntityName = useCallBack((entity) => {
//...get Entity name from list
}, [entityList]);
return <FlatList
data={entityList}
renderItem={RenderEntity({ getEntityName })}
/>
};
const RenderEntity = (props) => {
const { getEntityName } = props;
return (props) => {
const { item: entity } = props;
// This is where i get the error Invalid hook call;
const [entityName, setEntityName] = useState('');
useEffect(() => {
setEntityName(getEntityName(entity))
}, [entity])
return <ListItem
title={entityName}
/>
};

我不确定我到底做错了什么。任何相同的帮助将不胜感激。
感谢和问候。阿莫尔
您正在使用RenderEntityasfunction而不是 a functional component:
改变这个
renderItem={RenderEntity({ getEntityName })}

和 :
renderItem={({item, index, separators}) => <RenderEntity item={item} getEntityName={getEntityName}/> }
