Paging Library - Architecture Components
Sample created to practice Paging Library.
What Have I learned?
-
Paging Library: The Paging Library makes it easier for you to load data on demand within your app's RecyclerView.
-
PagedList: Collection that loads data in pages, asynchronously. A PagedList can be used to load data from sources you define, and present it easily in your UI with a RecyclerView.
-
DataSource and DataSource.Factory: DataSource is the base class for loading snapshots of data into a PagedList. A DataSource.Factory is used to create a DataSource.
-
PageKeyedDataSource: DataSource used to load embed next/previous keys.
-
ItemKeyedDataSource: DataSource used to retrieve data from item N to fetch item N+1
-
PositionalDataSource: if you need to fetch pages of data from any location you choose.
-
LivePagedListBuilder: Class used to build a LiveData based on DataSource.Factory and a PagedList.Config.
-
RxPagedListBuilder: Class used to build a Observable based on DataSource.Factory and a PagedList.Config.
-
BoundaryCallback: Helper callback to signals when a PagedList has reached the end of available data.
-
PagedListAdapter: RecyclerView.Adapter that presents paged data from PagedLists in a RecyclerView. PagedListAdapter listens to PagedList loading callbacks as pages are loaded, and uses DiffUtil to compute fine grained updates as new PagedLists are received.
