## Follow scroll

[![gif](https://raw.githubusercontent.com/florent37/ExpectAnim/master/media/scroll.gif)](https://github.com/florent37/ExpectAnim)

Use `setPercent` to apply modify the current step of the animation

Exemple with a scrollview

```java
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.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

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

# List of expectations

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

                    //.withMargin(marginPx)
                    //.withMarginDp(margin)
                    //.withMarginDimen(R.dimen.margin)

                    toRightOf(view)
                    toLeftOf(view)
                    belowOf(view)
                    aboveOf(view)

                    atHisOriginalPosition()


                    sameCenterAs(view, horizontal, vertical)
                    sameCenterHorizontalAs(view)
                    sameCenterVerticalAs(view)
                    centerInParent(horizontal, vertical)
                    centerVerticalInParent()
                    centerHorizontalInParent()

                    centerBetweenViews(view1, view2, horizontal, vertical)
                    centerBetweenViewAndParent(otherView, horizontal, vertical, toBeOnRight, toBeOnBottom)

                    topOfParent()
                    rightOfParent()
                    bottomOfParent()
                    leftOfParent()

                    alignBottom(otherView)
                    alignTop(otherView)
                    alignLeft(otherView)
                    alignRight(otherView)

                    outOfScreen(gravitiy)  //Gravity.LEFT / Gravity.RIGHT / Gravity.TOP / Gravity.BOTTOM

                    alpha(alpha)
                    sameAlphaAs(otherView)
                    visible()
                    invisible()

                    //.keepRatio()
                    //.withGravity(horizontalGravity, verticalGravity)

                    atHisOriginalScale()

                    scale(scaleX, scaleY)

                    toHaveTextColor(textColor)
                    toHaveBackgroundAlpha(alpha)

                )
