Known Direct Subclasses
|
A ViewHolder describes an item view and metadata about its place within the RecyclerView.
RecyclerView.Adapter implementations should subclass ViewHolder and add fields for caching
potentially expensive findViewById(int) results.
While RecyclerView.LayoutParams belong to the RecyclerView.LayoutManager,
ViewHolders belong to the adapter. Adapters should feel free to use
their own custom ViewHolder implementations to store data that makes binding view contents
easier. Implementations should assume that individual item views will hold strong references
to ViewHolder objects and that RecyclerView instances may hold
strong references to extra off-screen item views for caching purposes
