/**
 * Dispatch any dependent view changes to the relevant {@link Behavior} instances.

 * Usually run as part of the pre-draw step when at least one child view has a reported
 * dependency on another view. This allows CoordinatorLayout to account for layout
 * changes and animations that occur outside of the normal layout pass.
 *
 * It can also be ran as part of the nested scrolling dispatch to ensure that any offsetting
 * is completed within the correct coordinate window.
 *
 * The offsetting behavior implemented here does not store the computed offset in
 * the LayoutParams; instead it expects that the layout process will always reconstruct
 * the proper positioning.//from   w ww .j a v a 2  s . c o m
