- * ExpandoLayout is a ViewGroup which holds two views.  The "left view" is the view which
- * expands/contracts as needed.  The "right view" takes the remainder of the space (width)
- * of the ExpandoLayout and shifts right when the left view is expanded (this shift is
- * special because the right view retains it's width and doesn't squish down to fit
- * the newly reduced amount of space).
- *
- * The "left view" is the first child and the "right view" is the second child.  You must
- * have exactly two children.
- *
- * The left view's width is specified in dips.  This width is the collapsed width.
- * The ExpandoView object should contain an attribute called "expanded_layout_percentage" which
- * is a floating point number between 0 and 1.  When expanded, the left view expands to a width
- * which is this fraction of the ExpandLayout's width.  This can be controlled at runtime using
- * setParentPercentage().
- *
- * ExpandLayout's "start_expanded" (boolean) controls whether the initial state is expanded.
- * This defaults to false (contracted).
- *
- * The animation duration from collapsed to expanded and vice versa are controlled with these
- * attributes:
- *
- *    animation_expand_duration="250"
- *    animation_collapse_duration="250"
- *
- * In some cases you may want to override the left view in the collapsed state (i.e. to show
- * something other than a sliver of the normal left view).  To accomplish this make the left
- * view into a composite view (e.g. FrameLayout) containing two views.  The special view which
- * is to be shown when collapsed is referenced in the ExpandoLayout params as:
- *
- * collapsed_view="@+id/collapsed".
- *
- * ExpandoLayout will make that view visible/gone as needed.
