 * Measures the height of the given range of children (inclusive) and returns the height

 * measuring will stop when the current height reaches maxHeight.
 *
 * @param widthMeasureSpec             The width measure spec to be given to a child's
 *                                     {@link View#measure(int, int)}.
 * @param startPosition                The position of the first child to be shown.
 * @param endPosition                  The (inclusive) position of the last child to be
 *                                     shown. Specify {@link #NO_POSITION} if the last child
 *                                     should be the last available child from the adapter.
 * @param maxHeight                    The maximum height that will be returned (if all the
 *                                     children don't fit in this value, this value will be
 *                                     returned).
 * @param disallowPartialChildPosition In general, whether the returned height should only
 *                                     contain entire children. This is more powerful--it is
 *                                     the first inclusive position at which partial
 *                                     children will not be allowed. Example: it looks nice
 *                                     to have at least 3 completely visible children, and
 *                                     in portrait this will most likely fit; but in
 *                                     landscape there could be times when even 2 children
 *                                     can not be completely shown, so a value of 2
 *                                     (remember, inclusive) would be good (assuming
 *                                     startPosition is 0).
