Public constructors

public RecyclerViewAccessibilityDelegate.ItemDelegate (RecyclerViewAccessibilityDelegate recyclerViewDelegate)

Creates an item delegate for the given RecyclerViewAccessibilityDelegate.

Parameters

Public methods

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.
