Question

在尝试使用来自TelerikUI的RadListView时，我遇到了一个错误，我无法挂断。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";

和

@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，尝试使用

进行渲染

<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会抛出

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:

在我的android模拟器上（没有机会测试ios）

看起来，我对RadListView做了一个基本的错误，尽管我保持与angular app的nativescript-ui-samples完全对齐。

我的package.json摘录

    },

任何提示都受到高度赞赏。
