    android.support.v17.leanback.widget.FacetProviderAdapter

Public constructors

ItemBridgeAdapter

ItemBridgeAdapter (ObjectAdapter adapter, 
                PresenterSelector presenterSelector)

Parameters
`adapter`	`ObjectAdapter`
`presenterSelector`	`PresenterSelector`

ItemBridgeAdapter

ItemBridgeAdapter (ObjectAdapter adapter)

Parameters
`adapter`	`ObjectAdapter`

ItemBridgeAdapter

ItemBridgeAdapter ()

Public methods

clear

void clear ()

Clears the adapter.

getFacetProvider

FacetProvider getFacetProvider (int type)

Queries FacetProvider for a given type within Adapter.

Parameters
`type`	`int`: type of the item.

Returns
`FacetProvider`	Facet provider for the type.

getItemCount

int getItemCount ()

Returns the total number of items in the data set hold by the adapter.

Returns
`int`	The total number of items in this adapter.

getItemId

long getItemId (int position)

Return the stable ID for the item at position. If hasStableIds() would return false this method should return NO_ID. The default implementation of this method returns NO_ID.

Parameters
`position`	`int`: Adapter position to query

Returns
`long`	the stable ID of the item at position

getItemViewType

int getItemViewType (int position)

Return the view type of the item at position for the purposes of view recycling.

The default implementation of this method returns 0, making the assumption of a single view type for the adapter. Unlike ListView adapters, types need not be contiguous. Consider using id resources to uniquely identify item view types.

Parameters
`position`	`int`: position to query

Returns
`int`	integer value identifying the type of the view needed to represent the item at `position`. Type codes need not be contiguous.

getPresenterMapper

ArrayList<Presenter> getPresenterMapper ()

Returns the presenter mapper array.

Returns
`ArrayList<Presenter>`

getWrapper

ItemBridgeAdapter.Wrapper getWrapper ()

Returns the ItemBridgeAdapter.Wrapper.

Returns
`ItemBridgeAdapter.Wrapper`

onBindViewHolder

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 to reflect the item at the given position.

Note that unlike ListView, 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() which will have the updated adapter position. Override onBindViewHolder(ViewHolder, int, List) instead if Adapter can handle effcient 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.

onCreateViewHolder

RecyclerView.ViewHolder onCreateViewHolder (ViewGroup parent, 
                int viewType)

View.OnFocusChangeListener that assigned in onCreateViewHolder(ViewGroup) may be chained, user should never change View.OnFocusChangeListener 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`	A new ViewHolder that holds a View of the given view type.

onViewAttachedToWindow

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 those resources should be restored here.

Parameters
`holder`	`RecyclerView.ViewHolder`: Holder of the view being attached

onViewDetachedFromWindow

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 an detaching them as appropriate.

Parameters
`holder`	`RecyclerView.ViewHolder`: Holder of the view being detached

onViewRecycled

void onViewRecycled (RecyclerView.ViewHolder holder)

Called when a view created by this adapter has been recycled.

A view is recycled when a RecyclerView.LayoutManager decides that it no longer needs to be attached to its parent 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() to get its adapter position.

Parameters
`holder`	`RecyclerView.ViewHolder`: The ViewHolder for the view being recycled

setAdapter

void setAdapter (ObjectAdapter adapter)

Sets the ObjectAdapter.

Parameters
`adapter`	`ObjectAdapter`

setAdapterListener

void setAdapterListener (ItemBridgeAdapter.AdapterListener listener)

Sets the AdapterListener.

Parameters
`listener`	`ItemBridgeAdapter.AdapterListener`

setPresenterMapper

void setPresenterMapper (ArrayList<Presenter> presenters)

Sets the presenter mapper array.

Parameters
`presenters`	`ArrayList`

setWrapper

void setWrapper (ItemBridgeAdapter.Wrapper wrapper)

Sets the ItemBridgeAdapter.Wrapper.

Parameters
`wrapper`	`ItemBridgeAdapter.Wrapper`

Protected methods

onAddPresenter

void onAddPresenter (Presenter presenter, 
                int type)

Called when presenter is added to Adapter.

Parameters
`presenter`	`Presenter`
`type`	`int`

onAttachedToWindow

void onAttachedToWindow (ItemBridgeAdapter.ViewHolder viewHolder)

Called when ViewHolder has been attached to window.

Parameters
`viewHolder`	`ItemBridgeAdapter.ViewHolder`

onBind

void onBind (ItemBridgeAdapter.ViewHolder viewHolder)

Called when ViewHolder has been bound to data.

Parameters
`viewHolder`	`ItemBridgeAdapter.ViewHolder`

onCreate

void onCreate (ItemBridgeAdapter.ViewHolder viewHolder)

Called when ViewHolder is created.

Parameters
`viewHolder`	`ItemBridgeAdapter.ViewHolder`

onDetachedFromWindow

void onDetachedFromWindow (ItemBridgeAdapter.ViewHolder viewHolder)

Called when ViewHolder has been detached from window.

Parameters
`viewHolder`	`ItemBridgeAdapter.ViewHolder`

onUnbind

void onUnbind (ItemBridgeAdapter.ViewHolder viewHolder)

Called when ViewHolder has been unbound from data.

Parameters
`viewHolder`	`ItemBridgeAdapter.ViewHolder`
