Usage

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

private int predictFinalScrollPosition(int velocityX) {
    // 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 = Math.max(0, computeHorizontalScrollRange() - getWidth());
    int width = getWidth() - getPaddingStart() - getPaddingEnd();
    scroller.fling(getScrollX(), // startX
            getScrollY(), // startY
            velocityX, // velocityX
            0, // velocityY
            0, // minX
            maximumOffset, // maxX
            0, // minY
            0, // maxY
            width / 2, // overX
            0 // overY
