Usage

From source file:com.facebook.react.views.scroll.ReactScrollView.java

private int predictFinalScrollPosition(int velocityY) {
    // ScrollView can *only* scroll for 250ms when using smoothScrollTo and there's
    // no way to customize the scroll duration. So, we create a temporary OverScroller
    // so we can predict where a fling would land and snap to nearby that point.
    OverScroller scroller = new OverScroller(getContext());
    scroller.setFriction(1.0f - mDecelerationRate);

    // predict where a fling would end up so we can scroll to the nearest snap offset
    int maximumOffset = getMaxScrollY();
    int height = getHeight() - getPaddingBottom() - getPaddingTop();
    scroller.fling(getScrollX(), // startX
            getScrollY(), // startY
            0, // velocityX
            velocityY, // velocityY
            0, // minX
            0, // maxX
            0, // minY
            maximumOffset, // maxY
            0, // overX
            height / 2 // overY
