blackberry级联中的json数组listview

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.直接式

[
{"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"}
]

我的问题是如何为第一个json数组模型声明标题：ListItemData

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

这对我不起作用。我甚至尝试将

listItem

更改为

item

，并做了一些其他更改，但都没有成功。它甚至不显示ListView

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