In NativeScript with Angular2 get element value - nativescript

Question

I have a list, and I want to get the value of the list item.
The view is as follows
<ListView [items]="myItems" (itemTap)="onItemTap($event)">
<template let-item="item" let-i="index" let-odd="odd" let-even="even">
<StackLayout [class.odd]="odd" [class.even]="even">
<Label #myFoo id="grocery-list" [text]='"Value is: " + i'></Label>
</StackLayout>
</template>
In typescript I have the following
import { Component,ViewChild,ElementRef } from "#angular/core";
import {topmost} from "ui/frame";
import {ListView} from "ui/list-view";
export class AppComponent {
#ViewChild("myFoo") myFooRef: ElementRef;
public myItems = [];
constructor() {
this.myItems.push("1");
this.myItems.push("2");
this.myItems.push("3");
}
onItemTap(event){
}
}
I can do the following to get the value
onItemTap(event){
let itemValue = this.myItems[event.index];
console.log(itemValue);
}
This will get the value in the array. But this will return the value in the array only.
As you can see in the view I have the string Value is appended to the value.
So how can I access the text property of the label which is tapped on.

You can access the view of your item template via args.view. From that point, I assume that you will have different text in your list-items so it is important to create unique IDs for each Label via binding(using the Angular index). So you can do the following:
<ListView [items]="myItems" (itemTap)="onItemTap($event)">
<template let-item="item" let-i="index" let-odd="odd" let-even="even">
<StackLayout [class.odd]="odd" [class.even]="even">
<Label [id]="'lbl' + i" [text]='"Value is: " + i'></Label>
</StackLayout>
</template>
</ListView>
and then in your onItemTap
public onItemTap(args: ItemEventData) {
console.log("Item Tapped at cell index: " + args.index);
console.log(args.object); // prints something like ListView(137)
console.log(args.view); // prints something like StackLayout(265)
var lbl = <Label>args.view.getViewById("lbl" + args.index);
console.log(lbl.text); // prints the actual text of the tapped label
}
