var animation1 = view.createAnimation({ opacity: 0 });
var animation2 = view.createAnimation({ opacity: 1 });
animation1.play()
    .then(function () { return animation2.play(); })

item.src = "~/res/icon_100x100.png";
item.width = 90;
item.height = 90;
item.style.margin = "5,5,5,5";

infinite

JavaScript

animationSet = new animationModule.Animation([{
        target: view,
        rotate: 360,
        duration: 3000,
        iterations: Number.POSITIVE_INFINITY,

Rotation using originX and originY

Example 5: Rotating a view around its center. Center of view is changed via originX and originY properties.

rotation_origin_x_y

JavaScript
TypeScript

const view = page.getViewById("myView");

view.originX = 1; // default 0.5 (center), 0 is most left, 1 is most right
view.originY = 0; // default 0.5 (middle), 0 is top, 1 is bottom
view.animate({
    rotate: 360, // will take into account originX and originY
    duration: 1000
}).then(() => {
    view.originX = 0;
    view.originY = 1;
    view.rotate = 0;

    view.animate({
        rotate: -360,
        duration: 1000
    })
})

const view = page.getViewById("myView");

view.originX = 1; // default 0.5 (center), 0 is most left, 1 is most right
view.originY = 0; // default 0.5 (middle), 0 is top, 1 is bottom
view.animate({
    rotate: 360, // will take into account originX and originY
    duration: 1000
}).then(() => {
    view.originX = 0;
    view.originY = 1;
    view.rotate = 0;

    view.animate({
        rotate: -360,
        duration: 1000
    })
})

Animation - View's Width and Height

Width

JavaScript
TypeScript

let label = page.getViewById("lblNS");
let animation = new Animation([
    {
      width: 200,
      duration: 2000,
      target: label,
      delay: 200
    }

  ]);
animation.play();

let label: Label = <Label>page.getViewById("lblNS");
let animation = new Animation([
        {
            width: 200,
            duration: 2000,
            target: label,
            delay: 200
        }

    ]);
animation.play();

Height

JavaScript
TypeScript

let label = page.getViewById("lblNS");
let animation = new Animation([
    {
      height: 200,
      duration: 2000,
      target: label,
      delay: 200
    }

  ]);
animation.play();

let label: Label = <Label>page.getViewById("lblNS");
let animation = new Animation([
        {
            height: 200,
            duration: 2000,
            target: label,
            delay: 200
        }

    ]);
animation.play();
