getAccessibilityClassName

Added in API level 23
public CharSequence getAccessibilityClassName ()

Return the class name of this object to be used for accessibility purposes.

This is used to fill in AccessibilityNodeInfo.setClassName.

CharSequence

Returns the next view to be displayed.

Returns
View the view that will be displayed after the next views flip.

setFactory

Added in API level 1
public void setFactory (ViewSwitcher.ViewFactory factory)

Parameters
factory ViewSwitcher.ViewFactory: the view factory used to generate the switcher's content
