Angular

also in angular you can get a refrence to the target view using @ViewChild decorator as next

<Label #feat1 text="Feature 1"></Label>
<Label #feat2 text="Feature 2"></Label>
<Button text="start" tap="{{ startTour }}"></Button>

@ViewChild('feat1') feat1: ElementRef;
@ViewChild('feat2') feat2: ElementRef;

startTour(){

    const stops: TourStop[] = [
        {
            view: this.feat1.nativeElement,
            title: 'Feature 1',
            description: "Feature 1 Description",
            dismissable: true
        },
        {
            view: this.feat2.nativeElement,
            title: 'Feature 2',
            description: 'Feature 2 Description',
            outerCircleColor: 'orange',
            rippleColor: 'black'
        }
    ];

    const handlers: TourEvents = {
        finish() {
            console.log('Tour finished');
        },
        onStep(lastStopIndex) {
            console.log('User stepped', lastStopIndex);
        },
        onCancel(lastStopIndex) {
            console.log('User cancelled', lastStopIndex);
        }
    }

    this.tour = new AppTour(stops, handlers);
    this.tour.show();
}

Vue

While for Angular the {N} view representations of a referenced ViewChild is in the .nativeElement property, the naming in {N}-vue is a little confusing, since the {N} view of a referenced child is in .nativeView. Meaning that:

• this.$ref.feat1 return the vue view of the child object
• this.$ref.feat1.nativeView returns the {N} view, which we need to pass as a stop.view
• (this.$ref.feat1.nativeView.nativeView returns the actual native view)

<Label ref="feat1" text="Feature 1"></Label>
<Label ref="feat2" text="Feature 2"></Label>
<Button text="start" @tap="startTour"></Button>

startTour(){

    const stops = [
        {
            view: this.$ref.feat1.nativeView,
            title: 'Feature 1',
            description: "Feature 1 Description",
            dismissable: true
        },
        {
            view: this.$ref.feat2.nativeView,
            title: 'Feature 2',
            description: 'Feature 2 Description',
            outerCircleColor: 'orange',
            rippleColor: 'black'
        }
    ];

    const handlers = {
        finish() {
            console.log('Tour finished');
        },
        onStep(lastStopIndex) {
            console.log('User stepped', lastStopIndex);
        },
        onCancel(lastStopIndex) {
            console.log('User cancelled', lastStopIndex);
        }
    }

    this.tour = new AppTour(stops, handlers);
    this.tour.show();
}

Special cases on Android (ActionBar, TabView)

There are some special {N} UI Elements that cannot be accessed by simply using the {N} view of these objects, because it will result in an error Cannot convert object to Landroid/view/View.

An example for that is <ActionBar> and <ActionItem>. To access these, one has to find the nativeView by searching the right child of a referenced objects parent:

const stops = [{
    view: page.getViewById("actionItem").parent.nativeView.getChildAt(0).getChildAt(0),
    title: "Action Item",
    description: "Some Description"
}]

This is similar for <TabView> and <TabViewItem> and might also be for other special items.
