RadListView Telerik UI“无法读取未定义的属性'setLayoutParams'”

在尝试使用来自TelerikUI的RadListView时,我遇到了一个错误,我无法坚持下去 . 根据角度样本,我

在我的submodule.ts文件中导入模块

import { NativeScriptUIListViewModule } from "nativescript-telerik-ui/listview/angular";

@NgModule({


 imports: [
    NativeScriptModule,
    NativeScriptI18nModule,
    NativeScriptRouterModule,
    subRouting,
    NativeScriptUIListViewModule,
  ],
  declarations: [
    ListPageComponent,
  ],
  exports: [
  ]
})
export class SubModule {}

在ListPageComponent中创建了数据对象定义

class DataItem {
    constructor(public id: string, public type: string) { }
}

并编写了我的组件类

@Component({
    selector: "list",
    moduleId: module.id,
    templateUrl: "list.page.html",
    styleUrls: ["list.page.css"]
})
export class ListPageComponent implements OnInit {

    public _dataItems: DataItem[] = [
        {id: "1", type: "A"},
        {id: "2", type: "A"},
        {id: "3", type: "A"}
    ];
    get dataItems(): ObservableArray<DataItem> {
        return new ObservableArray(this._dataItems);
    }


    constructor(
        private _pageRoute: PageRoute,
        private _routerExtensions: RouterExtensions,
        private _page: Page
    ){
    }

    ngOnInit(): void {
    }        
}

最后,尝试渲染定义

<GridLayout columns="*" rows="*">
    <RadListView [items]="dataItems" col="0" row="1">
        <ng-template tkListItemTemplate let-item="item">
            <GridLayout columns="auto" rows="auto">
                <Label class="descriptionLabel" [text]="item.type" col="0" row="0"></Label>
            </GridLayout>
        </ng-template>        
    </RadListView>
</GridLayout>

该示例使用基本列表视图,但切换到RadListView抛出

An uncaught Exception occured on "main" thread. com.tns.NativeScriptException:
Calling js method onCreateViewHolder failed

Type Error: Cannot read property 'setLayoutParams' of undefined File: "file:///data/data/org.nativescript.myapp/files/app/tns_modules/nativescript-telerik-ui/listview/listview.js, line: 102 column: 42

StackTrace:

at com.tns.Runtime.callJSMethodNative (Native Method) [...]

在我的android模拟器上(没有机会在ios上测试)

看来,我正在做RadListView的一个基本问题,尽管我保持与angular应用程序的nativescript-ui-samples完全对齐 .

我的package.json摘录

"nativescript": {
        "id": "org.nativescript.myapp",
        "tns-android": {
            "version": "3.1.1"
        },
        "tns-ios": {
            "version": "3.1.0"
        }
    },
    "dependencies": {
        "@angular/animations": "~4.2.0",
        "@angular/common": "~4.2.0",
        "@angular/compiler": "~4.2.0",
        "@angular/core": "~4.2.0",
        "@angular/forms": "~4.2.0",
        "@angular/http": "~4.2.0",
        "@angular/platform-browser": "~4.2.0",
        "@angular/router": "~4.2.0",
        "moment": "^2.18.1",
        "nativescript-angular": "~4.2.0",

        "tns-core-modules": "~3.1.1",
        "zone.js": "~0.8.2"
    },

任何提示都非常感谢 .

谢谢 .
