For completeness:

public void hideContextMenu(MotionEvent ev) {
    if(contextMenuView == null)
        return;

    int[] contentLocation = new int[2];
    contextMenuView.getLocationOnScreen(contentLocation);
    Rect rect = new Rect(contentLocation[0],
            contentLocation[1],
            contentLocation[0] + contextMenuView.getWidth(),
            contentLocation[1] + contextMenuView.getHeight());

    if (!(rect.contains((int) ev.getX(), (int) ev.getY())))
        hideContextMenu();
}
