/**
 * Add a view as a child and make sure it is measured (if necessary) and positioned properly.
 *
 * @param child/*from w w  w  .j a v a  2  s. com*/
 *           The view to add
 * @param position
 *           The position of this child
 * @param x
 *           The x position relative to which this view will be positioned
 * @param flowDown
 *           If true, align left edge to x. If false, align right edge to x.
 * @param childrenTop
 *           Top edge where children should be positioned
 * @param selected
 *           Is this position selected?
 * @param recycled
 *           Has this view been pulled from the recycle bin? If so it does not need to be remeasured.
