ViewHolder

Kotlin |Java

open class ViewHolder : RecyclerView.ViewHolder, FacetProvider

kotlin.Any
↳	androidx.recyclerview.widget.RecyclerView.ViewHolder
	↳	androidx.leanback.widget.GuidedActionsStylist.ViewHolder

ViewHolder caches information about the action item layouts' subviews. Subclasses of may also wish to subclass this in order to add fields.

Summary

Public constructors
<init>(v: View!) Constructs an ViewHolder and caches the relevant subviews.
<init>(v: View!, isSubAction: Boolean) Constructs an ViewHolder for sub action and caches the relevant subviews.

Inherited functions

From class ViewHolder Int getAbsoluteAdapterPosition() Returns the Adapter position of the item represented by this ViewHolder with respect to the RecyclerView's Adapter. If the Adapter that bound this ViewHolder is inside another adapter (e.g. ConcatAdapter), this position might be different and will include the offsets caused by other adapters in the ConcatAdapter. Note that this might be different than the getLayoutPosition() if there are pending adapter updates but a new layout pass has not happened yet. RecyclerView does not handle any adapter updates until the next layout traversal. This may create temporary inconsistencies between what user sees on the screen and what adapter contents have. This inconsistency is not important since it will be less than 16ms but it might be a problem if you want to use ViewHolder position to access the adapter. Sometimes, you may need to get the exact adapter position to do some actions in response to user events. In that case, you should use this method which will calculate the Adapter position of the ViewHolder. Note that if you've called RecyclerView.Adapter#notifyDataSetChanged(), until the next layout pass, the return value of this method will be NO_POSITION. Note that if you are querying the position as RecyclerView sees, you should use getAbsoluteAdapterPosition() (e.g. you want to use it to save scroll state). If you are querying the position to access the Adapter contents, you should use getBindingAdapterPosition(). Int getAdapterPosition() RecyclerView.Adapter<out RecyclerView.ViewHolder!>? getBindingAdapter() Returns the Adapter that last bound this ViewHolder. Might return null if this ViewHolder is not bound to any adapter. Int getBindingAdapterPosition() Returns the Adapter position of the item represented by this ViewHolder with respect to the Adapter that bound it.
