Follow scroll

gif

Use setPercent to apply modify the current step of the animation

Exemple with a scrollview

this.expectAnimMove = new ExpectAnim()
                .expect(username)
                .toBe(
                        toRightOf(avatar).withMarginDp(16),
                        sameCenterVerticalAs(avatar),
                        alpha(0.5f)
                )

                .expect(avatar)
                .toBe(
                        topOfParent(),
                        leftOfParent().withMarginDp(16),
                        scale(0.5f, 0.5f)
                )
                .expect(follow)
                .toBe(
                        rightOfParent().withMarginDp(16),
                        sameCenterVerticalAs(avatar)
                )

                .expect(backbground)
                .toBe(
                        height(height).withGravity(Gravity.LEFT|Gravity.START, Gravity.TOP)
                )

                .toAnimation();

scrollView.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
    @Override
    public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
        final float percent = (scrollY * 1f) / v.getMaxScrollAmount();

        expectAnimMove.setPercent(percent);
    }
});

Apply directly

Use setNow to apply directly the transformation

new ExpectAnim()
                .expect(view)
                .toBe(
                        outOfScreen(Gravity.BOTTOM)
                )
                .toAnimation()
                .setNow();

Reset

Use reset to return to the initial state of views

expectAnim.reset():

List of expectations

new ExpectAnim()
                .expect(view)
                .toBe(
