【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.???????

【参考方案1】：

试试这个

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

【讨论】：

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
