    View.dispatchRestoreInstanceState(android.util.SparseArray), View.saveHierarchyState(android.util.SparseArray), View.onSaveInstanceState()
  - dispatchRestoreInstanceState
```
protected void dispatchRestoreInstanceState(SparseArray<Parcelable> container)

  - onDetachedFromWindow
```
protected void onDetachedFromWindow()

    Description copied from class: View
    
    This is called when the view is detached from a window. At this point it no longer has a surface for drawing.
    
    Overrides:
    
    onDetachedFromWindow in class View
    
    See Also:
    View.onAttachedToWindow()
  - dispatchPopulateAccessibilityEvent
```
public boolean dispatchPopulateAccessibilityEvent(AccessibilityEvent event)
```
    Description copied from class: View
    
    Dispatches an AccessibilityEvent to the View first and then to its children for adding their text content to the event. Note that the event text is populated in a separate dispatch path since we add to the event not only the text of the source but also the text of all its descendants. A typical implementation will call View.onPopulateAccessibilityEvent(AccessibilityEvent) on the this view and then call the View.dispatchPopulateAccessibilityEvent(AccessibilityEvent) on each child. Override this method if custom population of the event text content is required.
    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.dispatchPopulateAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.
    
    Note: Accessibility events of certain types are not dispatched for populating the event text via this method. For details refer to AccessibilityEvent.
    
    Overrides:
    
    dispatchPopulateAccessibilityEvent in class View
    
    Parameters:
    event - The event.
    
    Returns:
    True if the event population was completed.
  - onRequestSendAccessibilityEvent
```
public boolean onRequestSendAccessibilityEvent(View child,
                                      AccessibilityEvent event)
```
    Description copied from class: ViewGroup
    
    Called when a child has requested sending an AccessibilityEvent and gives an opportunity to its parent to augment the event.
    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(android.view.View.AccessibilityDelegate) its View.AccessibilityDelegate.onRequestSendAccessibilityEvent(ViewGroup, View, AccessibilityEvent) is responsible for handling this call.
    
    Overrides:
    
    onRequestSendAccessibilityEvent in class ViewGroup
    
    Parameters:
    child - The child which requests sending the event.
    event - The event to be sent.
    
    Returns:
    True if the event should be sent.
    See Also:
    ViewGroup.requestSendAccessibilityEvent(View, AccessibilityEvent)
  - onInitializeAccessibilityNodeInfo
```
public void onInitializeAccessibilityNodeInfo(AccessibilityNodeInfo info)
```
    Description copied from class: View
    Initializes an AccessibilityNodeInfo with information about this view. The base implementation sets:
    Subclasses should override this method, call the super implementation, and set additional attributes.
    
    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo) is responsible for handling this call.
    Overrides:
    
    onInitializeAccessibilityNodeInfo in class View
    
    Parameters:
    info - The instance to initialize.
  - onInitializeAccessibilityEvent
```
public void onInitializeAccessibilityEvent(AccessibilityEvent event)
```
    Description copied from class: View
    Initializes an AccessibilityEvent with information about this View which is the event source. In other words, the source of an accessibility event is the view whose state change triggered firing the event.
    Example: Setting the password property of an event in addition to properties set by the super implementation:
```
 public void onInitializeAccessibilityEvent(AccessibilityEvent event) {
     super.onInitializeAccessibilityEvent(event);
     event.setPassword(true);
 }
```
    If an View.AccessibilityDelegate has been specified via calling View.setAccessibilityDelegate(AccessibilityDelegate) its View.AccessibilityDelegate.onInitializeAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.
    
    Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add.
    Overrides:
    
    onInitializeAccessibilityEvent in class View
    
    Parameters:
    event - The event to initialize.
    See Also:
    View.sendAccessibilityEvent(int), View.dispatchPopulateAccessibilityEvent(AccessibilityEvent)
  - canAnimate
```
protected boolean canAnimate()
```
    Description copied from class: ViewGroup
    
    Indicates whether the view group has the ability to animate its children after the first layout.
    
    Overrides:
    
    canAnimate in class ViewGroup
    
    Returns:
    true if the children can be animated, false otherwise
