如何根据 SectionList 中的键在 ui 上填充数组的值

Question

在我的代码中，我低于数组值，并根据 SectionList 中的键填充这些值。 UI 中的所有键值都正确，但在我的 renderitem 中我遇到了一些问题。请参阅下面的第二部分我已经解释了更多。基本上在渲染函数中我也想传递键值

//下面是数组值

 customerSearch:[
                    {
                      "key": "Customer",
                      "data": [
                        {
                          "name": "John",
                          "status": "Active",
                          "nationalId": "NBGVH6676",
                          "flag": "cus",
                        },
                        { "name": "Abhi",
                          "status": "Active",
                          "nationalId": "NBGVH6890",
                          "flag": "cus"
                        }
                      ]
                    },
                    {
                      "key": "Requests",
                      "data": [
                        {
                          "name": "Request 1",
                          "status": "Active",
                          "nationalId": "K0089"
                        },
                        { "name": "Request 2",
                          "status": "Active",
                          "nationalId": "AS420"

                        }
                      ]
                    },
                    {
                      "key": "Invoice",
                      "data": [
                        {
                          "name": "Invoice No 1",
                          "status": "Active",
                          "nationalId": "IN998"
                        },
                        { "name": "Invoice No 2",
                          "status": "Active",
                          "nationalId": "ABh007"

                        }
                      ]
                    },
                  ]

// 这里我在特定键中填充数据在我这里，我得到了键值内的那个数组。虽然我必须在 "Customer" 键中添加一些条件，但我必须显示 Avatar 。但是这里没有关键值。请帮助

在您的 renderItems 方法中，您还需要解构 section。然后您可以使用 section.key 访问密钥。

代码：

renderItems = ({ item, section }) => (
   const key = section.key;
   // other Code ...
);
