TextInput字段未在Map函数react native中获取值

Question

我想在Textinput字段中获取"DeliveredQuantity"，有人知道这个的解决方案吗

const [arrayList, setArraylist]= [
{id:0, ExpectedQuantity:10, DeliveredQuantity:7},
{id:1, ExpectedQuantity:19, DeliveredQuantity:9},
{id:2, ExpectedQuantity:11, DeliveredQuantity:11},
{id:3, ExpectedQuantity:45, DeliveredQuantity:30},
]
arrayList.map((items,index)=>{ 
return
<TextInput  value={items.DeliveredQuantity} />
})

Answer 1

将数组存储在一个状态中，并像这样使用

const [arrayList, setArraylist] = React.useState([
{ id: 0, ExpectedQuantity: 10, DeliveredQuantity: 7 },
{ id: 1, ExpectedQuantity: 19, DeliveredQuantity: 9 },
{ id: 2, ExpectedQuantity: 11, DeliveredQuantity: 11 },
{ id: 3, ExpectedQuantity: 45, DeliveredQuantity: 30 },
]);
return (
<View style={styles.container}>
{arrayList.map((items, index) => (
<TextInput value={items.DeliveredQuantity} />
))}
</View>
);
