Scroll an android ScrollView to a non-direct child

DeepScrollView.java

public class DeepScrollView extends ScrollView {


	public ShrinkWatchScrollView(Context context, AttributeSet attrs,
			int defStyle) {
		super(context, attrs, defStyle);
	}

	public ShrinkWatchScrollView(Context context, AttributeSet attrs) {
		this(context, attrs, 0);
	}

	public ShrinkWatchScrollView(Context context) {
		super(context);
	}


	public void scrollToDeepChild(View child) {
		Point childOffset = new Point();

		getDeepChildOffset(child.getParent(), child, childOffset);


		Rect childRect = new Rect(childOffset.x, childOffset.y, childOffset.x + child.getWidth(), childOffset.y + child.getHeight());
		int deltay = computeScrollDeltaToGetChildRectOnScreen(childRect);
		smoothScrollBy(0, deltay);
	}

	private void getDeepChildOffset(ViewParent nextParent, View nextChild, Point accumulatedOffset) {
		ViewGroup parent = (ViewGroup) nextParent;
		accumulatedOffset.x += nextChild.getLeft();
		accumulatedOffset.y += nextChild.getTop();
		if(parent == this) {
			return;
		}
		getDeepChildOffset(parent.getParent(), parent, accumulatedOffset);
	}

}

it doesn't work :(
