.ToAnimation()
.SetDuration(1500)
.Start();Follow scroll
Use SetPercent to apply modify the current step of the animation
Exemple with a scrollview
_expectAnimMove = new ExpectAnim()
.Expect(_avatar)
.ToBe(
TopOfParent().WithMarginDp(20),
LeftOfParent().WithMarginDp(20),
Scale(0.5f, 0.5f)
)
.Expect(_username)
.ToBe(
ToRightOf(_avatar).WithMarginDp(16),
SameCenterVerticalAs(_avatar),
Alpha(0.5f)
)
.Expect(_follow)
.ToBe(
RightOfParent().WithMarginDp(20),
SameCenterVerticalAs(_avatar)
)
.Expect(_background)
.ToBe(
Height(_height).WithGravity(Java.Lang.Integer.ValueOf((int)GravityFlags.Left), Java.Lang.Integer.ValueOf((int)GravityFlags.Top))
)
.ToAnimation();
_scrollView.ScrollChange += (sender, args) => {
float percent = args.ScrollY * 1f / _scrollView.MaxScrollAmount;
_expectAnimMove.SetPercent(percent);
};Apply directly
Use SetNow to apply directly the transformation
new ExpectAnim()
.Expect(_view).ToBe(Invisible())
.ToAnimation()
.SetNow();Reset
Use reset to return to the initial state of views
_expectAnimMove.Reset():List of expectations
