Usage

From source file:ti.modules.titanium.ui.widget.TiUIScrollView.java

public void scrollTo(int x, int y, boolean smoothScroll) {
    // Fetch the scroll view.
    final View view = this.scrollView;
    if (view == null) {
        return;/*from ww w .ja  v  a2  s  .  co m*/
    }

    // Convert the given coordinates to pixels.
    x = TiConvert.toTiDimension(x, -1).getAsPixels(view);
    y = TiConvert.toTiDimension(y, -1).getAsPixels(view);

    // Disable smooth scrolling for vertical scroll views if not at top of view.
    // Note: This works-around a bug in Google's NestedScrollView where attempting to
    //       smooth scrolls will move to a totally different position or opposite directions.
    if (smoothScroll && (view instanceof TiVerticalScrollView)) {
        if (((TiVerticalScrollView) view).getScrollY() > 0) {
            smoothScroll = false;
        }
    }

    // Scroll to the given position.
    if (smoothScroll) {
        if (view instanceof TiHorizontalScrollView) {
            ((TiHorizontalScrollView) view).smoothScrollTo(x, y);
        } else if (view instanceof TiVerticalScrollView) {
            ((TiVerticalScrollView) view).smoothScrollTo(x, y);
        }
    } else {
        view.scrollTo(x, y);
    }
    view.computeScroll();
