ItemDetailsLookup

public abstract class ItemDetailsLookup<K>

The Selection library calls getItemDetails when it needs access to information about the area and/or ItemDetails under a MotionEvent. Your implementation must negotiate ViewHolder lookup with the corresponding RecyclerView instance, and the subsequent conversion of the ViewHolder instance to an ItemDetails instance.

Example

final class MyDetailsLookup extends ItemDetailsLookup{

  private final RecyclerView mRecyclerView;

  MyDetailsLookup(RecyclerView recyclerView) {
      mRecyclerView = recyclerView;
  }

  public @Nullable ItemDetails
Parameters
<K>

Selection key type. @see StorageStrategy for supported types.
