@ohos.animation.windowAnimationManager (Window Animation Management)

The WindowAnimationManager module provides APIs to listen for application start/exit events and window minimization/maximization events and associate animations with these events.

NOTE

The APIs of this module are supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.

The APIs provided by this module are system APIs.

Modules to Import

import windowAnimationManager from '@ohos.animation.windowAnimationManager'

windowAnimationManager.setController

setController(controller: WindowAnimationController): void

Sets a window animation controller. For details about the controller, see WindowAnimationController.

Before using other APIs of windowAnimationManager, you must call this API to set a window animation controller.

System capability: SystemCapability.WindowManager.WindowManager.Core

Parameters
