| ### getWrapper added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` ItemBridgeAdapter.Wrapper getWrapper () ``` Returns the[ItemBridgeAdapter.Wrapper](https://developer.android.com/reference/android/support/v17/leanback/widget/ItemBridgeAdapter.Wrapper).
| Returns || |------------------------------------------------------------------------------------------------------------------------------------|--------| | [ItemBridgeAdapter.Wrapper](https://developer.android.com/reference/android/support/v17/leanback/widget/ItemBridgeAdapter.Wrapper) |
| ### onBindViewHolder added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void onBindViewHolder (RecyclerView.ViewHolder holder, int position) ``` Called by RecyclerView to display the data at the specified position. This method should update the contents of the[itemView](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#itemView)to reflect the item at the given position. Note that unlike[ListView](https://developer.android.com/reference/android/widget/ListView.html), RecyclerView will not call this method again if the position of the item changes in the data set unless the item itself is invalidated or the new position cannot be determined. For this reason, you should only use the`position`parameter while acquiring the related data item inside this method and should not keep a copy of it. If you need the position of an item later on (e.g. in a click listener), use[getAdapterPosition()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#getAdapterPosition())which will have the updated adapter position. Override[onBindViewHolder(ViewHolder, int, List)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter#onBindViewHolder(VH, int, java.util.List))instead if Adapter can handle efficient partial bind.
| Parameters || |------------|-------------------------------------------------------------------------------------------------------------------------------------------------------| | `holder` | `RecyclerView.ViewHolder`: The ViewHolder which should be updated to represent the contents of the item at the given position in the data set.
| | `position` | `int`: The position of the item within the adapter's data set.
| ### onBindViewHolder added in[version 27.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void onBindViewHolder (RecyclerView.ViewHolder holder, int position, List payloads) ``` Called by RecyclerView to display the data at the specified position. This method should update the contents of the[itemView](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#itemView)to reflect the item at the given position. Note that unlike[ListView](https://developer.android.com/reference/android/widget/ListView.html), RecyclerView will not call this method again if the position of the item changes in the data set unless the item itself is invalidated or the new position cannot be determined. For this reason, you should only use the`position`parameter while acquiring the related data item inside this method and should not keep a copy of it. If you need the position of an item later on (e.g. in a click listener), use[getAdapterPosition()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#getAdapterPosition())which will have the updated adapter position. Partial bind vs full bind: The payloads parameter is a merge list from[notifyItemChanged(int, Object)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter#notifyItemChanged(int, java.lang.Object))or[notifyItemRangeChanged(int, int, Object)](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter#notifyItemRangeChanged(int, int, java.lang.Object)). If the payloads list is not empty, the ViewHolder is currently bound to old data and Adapter may run an efficient partial update using the payload info. If the payload is empty, Adapter must run a full bind. Adapter should not assume that the payload passed in notify methods will be received by onBindViewHolder(). For example when the view is not attached to the screen, the payload in notifyItemChange() will be simply dropped.
| Parameters || |------------|-------------------------------------------------------------------------------------------------------------------------------------------------------| | `holder` | `RecyclerView.ViewHolder`: The ViewHolder which should be updated to represent the contents of the item at the given position in the data set.
| | `position` | `int`: The position of the item within the adapter's data set.
| | `payloads` | `List`: A non-null list of merged payloads. Can be empty list if requires full update.
| ### onCreateViewHolder added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` RecyclerView.ViewHolder onCreateViewHolder (ViewGroup parent, int viewType) ``` [View.OnFocusChangeListener](https://developer.android.com/reference/android/view/View.OnFocusChangeListener.html)that assigned in[onCreateViewHolder(ViewGroup)](https://developer.android.com/reference/android/support/v17/leanback/widget/Presenter#onCreateViewHolder(android.view.ViewGroup))may be chained, user should never change[View.OnFocusChangeListener](https://developer.android.com/reference/android/view/View.OnFocusChangeListener.html)after that.
| Parameters || |------------|-------------------------------------------------------------------------------------------------------------------| | `parent` | `ViewGroup`: The ViewGroup into which the new View will be added after it is bound to an adapter position.
| | `viewType` | `int`: The view type of the new View.
| | Returns || |----------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------| | [RecyclerView.ViewHolder](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder) | A new ViewHolder that holds a View of the given view type.
| ### onViewAttachedToWindow added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void onViewAttachedToWindow (RecyclerView.ViewHolder holder) ``` Called when a view created by this adapter has been attached to a window. This can be used as a reasonable signal that the view is about to be seen by the user. If the adapter previously freed any resources in[onViewDetachedFromWindow](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter#onViewDetachedFromWindow(VH))those resources should be restored here.

| Parameters || |----------|---------------------------------------------------------------------| | `holder` | `RecyclerView.ViewHolder`: Holder of the view being attached
| ### onViewDetachedFromWindow added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void onViewDetachedFromWindow (RecyclerView.ViewHolder holder) ``` Called when a view created by this adapter has been detached from its window. Becoming detached from the window is not necessarily a permanent condition; the consumer of an Adapter's views may choose to cache views offscreen while they are not visible, attaching and detaching them as appropriate.

| Parameters || |----------|---------------------------------------------------------------------| | `holder` | `RecyclerView.ViewHolder`: Holder of the view being detached
| ### onViewRecycled added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void onViewRecycled (RecyclerView.ViewHolder holder) ``` Called when a view created by this adapter has been recycled. A view is recycled when a[RecyclerView.LayoutManager](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.LayoutManager)decides that it no longer needs to be attached to its parent[RecyclerView](https://developer.android.com/reference/android/support/v7/widget/RecyclerView). This can be because it has fallen out of visibility or a set of cached views represented by views still attached to the parent RecyclerView. If an item view has large or expensive data bound to it such as large bitmaps, this may be a good place to release those resources. RecyclerView calls this method right before clearing ViewHolder's internal data and sending it to RecycledViewPool. This way, if ViewHolder was holding valid information before being recycled, you can call[getAdapterPosition()](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.ViewHolder#getAdapterPosition())to get its adapter position.
| Parameters || |----------|------------------------------------------------------------------------------| | `holder` | `RecyclerView.ViewHolder`: The ViewHolder for the view being recycled
| ### setAdapter added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setAdapter (ObjectAdapter adapter) ``` Sets the[ObjectAdapter](https://developer.android.com/reference/android/support/v17/leanback/widget/ObjectAdapter).
| Parameters || |-----------|------------------------| | `adapter` | `ObjectAdapter`
| ### setAdapterListener added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setAdapterListener (ItemBridgeAdapter.AdapterListener listener) ``` Sets the AdapterListener.
| Parameters || |------------|--------------------------------------------| | `listener` | `ItemBridgeAdapter.AdapterListener`
| ### setPresenter added in[version 25.4.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setPresenter (PresenterSelector presenterSelector) ``` Changes Presenter that creates and binds the view.
| Parameters || |---------------------|------------------------------------------------------------------------| | `presenterSelector` | `PresenterSelector`: Presenter that creates and binds the view.
| ### setPresenterMapper added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setPresenterMapper (ArrayList presenters) ``` Sets the presenter mapper array.
| Parameters || |--------------|--------------------| | `presenters` | `ArrayList`
| ### setWrapper added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setWrapper (ItemBridgeAdapter.Wrapper wrapper) ``` Sets the[ItemBridgeAdapter.Wrapper](https://developer.android.com/reference/android/support/v17/leanback/widget/ItemBridgeAdapter.Wrapper).
| Parameters || |-----------|------------------------------------| | `wrapper` | `ItemBridgeAdapter.Wrapper`
