用对象项填充 listView 的正确方法？

在我的 NativeScript 项目中，我尝试使用自定义对象（定义为接口）的实例填充 ListView。但输出（在 Android 模拟器上）非常奇怪：我在多行中生成了“[object object ... object]”，而不是按照我的定义获取每个实例名称内容。

这是我的 component.ts ：

import {Component} from "@angular/core";

interface FileItem {
    isDirectory:boolean;
    name:String;
}

@Component({
    moduleId: module.id,
    selector: 'file-explorer',
    templateUrl: 'component.html',
    styleUrls: ['component.css']
})
export class FileExplorerComponent {
    public fileItems:Array<FileItem>;

    constructor(){
        this.fileItems = [
            {isDirectory: false, name:'ex03.fen'},
            {isDirectory: true, name:'test06'},
            {isDirectory: true, name:'test01'},
            {isDirectory: false, name:'ex02.fen'},
            {isDirectory: true, name:'test05'},
            {isDirectory: true, name:'test02'},
            {isDirectory: false, name:'ex01.fen'},
            {isDirectory: false, name:'ex05.fen'},
            {isDirectory: false, name:'ex03.fen'},
            {isDirectory: true, name:'test04'},
            {isDirectory: true, name:'test03'},
            {isDirectory: false, name:'ex04.fen'},
        ]
    }
}

这是我的 component.html：

<ListView items={{fileItems}}>
    <ListView.itemTemplate>
        <Label width="5%" height="5%" text="Type"></Label>
        <Label text="{{name}}"></Label>
    </ListView.itemTemplate>
</ListView>

这是我的组件.css：

Label {
    color: navy;
    font-size: 20em;
}

所有这些文件都是单个组件的一部分，在其自己的文件夹中定义

这是我的 package.json ：

    }
}

我使用的是nativeScript 2.0.1

使用 NativeScript + Angular-2 列表视图时需要以下语法：

<ListView [items]="fileItems">
    <template let-myitem="item">
        <StackLayout>
            <Label width="5%" height="5%" text="Type"></Label>
            <Label [text]="myitem.name"></Label>
        </StackLayout>
    </template>
</ListView>
