GarlandView
consists of classes for inner items that are scrolled vertically
and outer items that are scrolled horizontally, and each of which contains
one inner item.
First of all, you need to implement the classes necessary to create internal items: InnerItem and InnerAdapter.
InnerAdapter
is an abstract class inherited from RecyclerView.Adapter.
It works only with InnerItem - ViewHolder.
In InnerItem
, you need to override the getInnerLayout
method, which must return
the main layout of the inner item.
Next, you need to override the classes required for external items: HeaderItem
and HeaderAdapter
.
HeaderAdapter
is an abstract class inherited from RecyclerView.Adapter,
It works only with HeaderItem - ViewHolder.
In HeaderItem
, you need to redefine 4 methods: getHeader
, getHeaderAlphaView
, isScrolling
, getViewGroup
.
The method getViewGroup
should return InnerRecyclerView.
The isScrolling
method must return the InnerRecyclerView's scrolling state.
The getHeaderAlpha
method should return an alpha-layout, which will be used for dimming (hiding header's views).
The getHeader
method must return the main layout of the header, an outer item.
Finally, place TailRecyclerView
in the Activity's layout. Next, create a TailLayoutManager and
specify it as a LayoutManager for TailRecyclerView
.
Here are the attributes of TailRecyclerView
you can specify in the XML layout:
itemStart
- Outer item left and right offset size.itemGap
- Distance between outer items.
