Nativescript radListView无法按ID获取项目

Question

嗨我正在使用带角度2的{N} 从RadListView

访问Id中的视图时出现以下错误

<RadListView id="listView" [items]="posts" loadOnDemandMode="Manual" scrollDirection="Vertical"
             itemInsertAnimation="Fade" itemDeleteAnimation="Fade"
             (loadMoreDataRequested)="onLoadMoreItemsRequested($event)">
    <template tkListItemTemplate let-post="item">
        <CardView id="post-{{ post.kl_id }}" margin="8 0 8 0" elevation="15" class="whiteCard" shadowOffsetHeight="3" shadowOffsetWidth="1">
            <Label (tap)="doSomethingWithPost(post)"></Label>
        </CardView>
    </template>
</RadListView>

在我的组件中

let view = require("ui/core/view");
doSomethingWithPost(post){
 let postGridLayout = view.getViewById(this.page, "post-" + post.kl_id);
}

我收到以下错误

TypeError: undefined is not an object (evaluating 'value.view.itemView')

Answer 1

使用viewChild

@ViewChild(/* id like*/ 'foo') myElement: ElementRef;

 ngAfterViewInit() {
    let myfoo= this.myElement
}
