CHANGELOG.md

Version 3.0.0-RC1 (10/07/16)

• Added implementation of notifyDataSetChanged() called notifyParentDataSetChanged(), please read the documentation for the method before considering using it.
• Added generic types for the Parent and Child model objects inside of ExpandableRecyclerAdapter
  • ParentListItem interface now takes a generic object type, which allows for getChildItemList to return a typed List instead of List<?>
  • The ExpandableRecyclerAdapter takes two more generic object types
    • A child model object of any type
    • A parent model object that must extend ParentListItem which includes the previous child type
  • As a result onBindParentViewHolder and onBindChildViewHolder now give the specific object type specified in the class
  • Cleaned up a lot of internal logic within ExpandableRecyclerAdapter to avoid casting to Object
  • Removed protected method getListItem, with generics it is now more sane to access mItemList yourself if you need it in the subclass
• Rename of ParentListItem and ChildListItem, this affects many getters and setters names to eliminate the item word. Some examples:
  • Parent interface now has the method getChildList() instead of getChildItemList()
  • ExpandableRecyclerAdapter renamed method from getParentItemList() to getParentList()
  • All the notify methods now are name notifyParent... instead of of notifyParentItem... (Same for children)
  • The ExpandCollapseListener has methods onParentExpanded and onParentCollapsed instead of onListItemExpanded
• Changed the name and visibility of onParentListItemExpanded and onParentListItemCollapsed
  • Now protected and named parentExpandedFromViewHolder and parentCollapsedFromViewHolder
  • Not meant to be called from outside the adapter and viewholder, can be overriden to give some custom behaviour for collapsing/expanding
• Added support for multiple view types within recyclerview
  • getParentViewType(), getChildViewType(), and isParentViewType() added with default implementation for single view type
  • Modified signatures of onCreateParentViewHolder() and onCreateChildViewHolder() to pass view type being created
• ParentViewHolder package location modified from com.bignerdranch.expandablerecyclerview.Adapter.ExpandableRecyclerAdapter to com.bignerdranch.expandablerecyclerview.ExpandableRecyclerAdapter
• ChildViewHolder package location modified from com.bignerdranch.expandablerecyclerview.Adapter.ExpandableRecyclerAdapter to com.bignerdranch.expandablerecyclerview.ExpandableRecyclerAdapter
• Added ParentViewHolder methods:
  • getParent()
  • getParentAdapterPosition()
• Added ChildViewHolder methods:
  • getChild()
  • getParentAdapterPosition()
  • getChildAdapterPosition()
• Added SimpleParentListItem for quick implementation of ParentListItem interface (no need to override methods or subclass)

Version 2.1.1 (2/26/16)

• Updated Support Library dependencies

Version 2.1.0 (1/8/16)

• Improved expand/collapse performance
  • Reduced frequency of notify calls in expand/collapse methods
• Added ability to expand and collapse list items by range
  • Added ExpandableRecyclerAdapter.expandParentRange so that a subset of parents in a list can be expanded at once with one call
  • Added ExpandableRecyclerAdapter.collapseParentRange so that a subset of parents in a list can be collapsed at once with one call
• Added additional notifyDatasetChanged methods
  • Added ExpandableRecyclerAdapter.notifyParentItemRangeRemoved to notify the RecyclerView when a subset of parents is removed
  • Added ExpandableRecyclerAdapter.notifyParentItemRangeChanged to notify the RecyclerView when a subset of parents is changed
  • Added ExpandableRecyclerAdapter.notifyChildItemRangeInserted to notify the RecyclerView when a subset of children is inserted
  • Added ExpandableRecyclerAdapter.notifyChildItemRangeRemoved to notify the RecyclerView when a subset of children is removed
  • Added ExpandableRecyclerAdapter.notifyChildItemRangeChanged to notify the RecyclerView when a subset of children is changed
  • Added ExpandableRecyclerAdapter.notifyParentItemMoved to notify the RecyclerView when a parent's adapter position is changed
  • Added ExpandableRecyclerAdapter.notifyChildItemMoved to notify the RecyclerView when a child's adapter position is changed
• Replaced content in vertical linear sample with a more realistic, food-themed example

Version 2.0.4 (11/20/15)

• Fix crash when restoring state when an initially expanded row has been collapsed

Version 2.0.3 (10/14/15)

• Change onListItemExpanded and onListItemCollapsed to be called after list is updated, fixes bug in issue #112

Version 2.0.2 (10/13/15)

• Fix notifyChildItemChanged and notifyParentItemChanged, previously child objects were not being replaced

Version 2.0.1 (10/05/15)

• Fix crash occurring when using notifyParentItemRangeInserted to add a group of items at the end of the list

Version 2.0.0 (09/24/15)

For a migration guide from 1.0.3 to 2.0.0, see here.

• Significant renaming/reorganizing of library
  • ParentObject is now named ParentListItem.
  • ExpandableRecyclerAdapter#mHelperItemList now has protected visibility and is named mItemList. This List can be used to gain access to all expanded list items.
  • ParentItemClickListener is now ParentViewHolder.ParentListItemExpandCollapseListener.
• Fleshed out Javadocs.
• Added ability to specify if a parent should be expanded initially.
• Added ability to expand and collapse list items programmatically (without relying on a click event).
• Added ExpandableRecyclerAdapter.ExpandCollapseListener.
• Added horizontal linear sample project, demoing many of the new features in 2.0.0.
• Added ability to notify the adapter of changes to the parent list items and child items. Methods begin with notifyParentItem or notifyChildItem
  • Note: RecyclerView.Adapter's notify methods will not work correctly with this adapter.
• Reorganized sample project.
• Removed setChildObjectList from ParentListItem interface.
• Removed inaccurate "stable" id map.
• Removed application tag from manifest.
• Removed animation and click handling details from the adapter, ParentViewHolder now has methods used for implementing that behavior in your own subclasses (examples given in the samples with this library).
• README updates
  • Added usage instructions for new features.
  • Updated references to the library where naming has changed.
• Bug fixes: #42, #46, #47

Version 1.0.3 (06/19/15)

• Initial Version
