【问题描述】：

1.数组类型

{"DATA":
[
{"CategoryID":"3","CategoryName":"News","CountryID":"1","Result":"OK"},
{"CategoryID":"4","CategoryName":"Daily Paper","CountryID":"1","Result":"OK"},
{"CategoryID":"5","CategoryName":"Thanthi","CountryID":"1","Result":"OK"},
{"CategoryID":"1","CategoryName":"Newspaper","CountryID":"1","Result":"OK"},
{"CategoryID":"2","CategoryName":"Magazine","CountryID":"1","Result":"OK"}
]
}

2.直接类型

[
{"CategoryID":"3","CategoryName":"News","CountryID":"1","Result":"OK"},
{"CategoryID":"4","CategoryName":"Daily Paper","CountryID":"1","Result":"OK"},
{"CategoryID":"5","CategoryName":"Thanthi","CountryID":"1","Result":"OK"},
{"CategoryID":"1","CategoryName":"Newspaper","CountryID":"1","Result":"OK"},
{"CategoryID":"2","CategoryName":"Magazine","CountryID":"1","Result":"OK"}
]

对于直接类型声明--->

 ListItemComponent {
     type: "listItem"
     StandardListItem {
         title: ListItemData.CategoryName
     }
 }

我的问题是如何为第一个 json 数组模型声明 title: ListItemData.???????

【解决方案1】：

试试这个

ListItemComponent {
 type: "listItem"
 StandardListItem {
 title: ListItemData.DATA[0].CategoryName
 }
 }

它对我不起作用。我什至尝试将listItem 更改为item 以及其他一些更改，但它们都没有奏效。它甚至不显示 ListView
