Parameters
`recyclerView`	`RecyclerView`

Public methods

getItemDelegate

public AccessibilityDelegateCompat getItemDelegate ()

Gets the AccessibilityDelegate for an individual item in the RecyclerView. A basic item delegate is provided by default, but you can override this method to provide a custom per-item delegate. For now, returning an AccessibilityDelegateCompat as opposed to an ItemDelegate will prevent use of the ViewCompat accessibility API on item views.

Returns
`AccessibilityDelegateCompat`

onInitializeAccessibilityEvent

public void onInitializeAccessibilityEvent (View host, 
                AccessibilityEvent event)

Initializes an AccessibilityEvent with information about the the host View which is the event source.

The default implementation behaves as ViewCompat#onInitalizeAccessibilityEvent(View v, AccessibilityEvent event) for the case of no accessibility delegate been set.

Parameters
`host`	`View`: The View hosting the delegate.
`event`	`AccessibilityEvent`: The event to initialize.

onInitializeAccessibilityNodeInfo

public void onInitializeAccessibilityNodeInfo (View host, 
                AccessibilityNodeInfoCompat info)

Initializes an AccessibilityNodeInfoCompat with information about the host view.

The default implementation behaves as ViewCompat#onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfoCompat) for the case of no accessibility delegate been set.

Parameters
`host`	`View`: The View hosting the delegate.
`info`	`AccessibilityNodeInfoCompat`: The instance to initialize.

performAccessibilityAction

public boolean performAccessibilityAction (View host, 
                int action, 
                Bundle args)

Performs the specified accessibility action on the view. For possible accessibility actions look at AccessibilityNodeInfoCompat.

The default implementation behaves as View#performAccessibilityAction(int, Bundle) for the case of no accessibility delegate been set.

Parameters
`host`	`View`
`action`	`int`: The action to perform.
`args`	`Bundle`

Returns
`boolean`	Whether the action was performed.
