Available on crate feature api-12 only.

Implements the native animation APIs provided by ArkUI.

Version: 1

Available since API-level: 12

Fields

animateTo: Option<unsafe extern "C" fn(context: ArkUI_ContextHandle, option: *mut ArkUI_AnimateOption, update: *mut ArkUI_ContextCallback, complete: *mut ArkUI_AnimateCompleteCallback) -> i32>

Defines an explicit animation.

Note:** Make sure the component attributes to be set in the event closure have been set before.

Arguments

context - Indicates a UIContext instance.

option - Indicates the pointer to an animation configuration.

update - Indicates the animation closure. The system automatically inserts a transition animation for the state change caused by the closure.

complete - Indicates the callback to be invoked when the animation playback is complete.

Returns

Returns the error code. Returns [ARKUI_ERROR_CODE_NO_ERROR] if the operation is successful. Returns [ARKUI_ERROR_CODE_PARAM_INVALID] if a parameter error occurs.

keyframeAnimateTo: Option<unsafe extern "C" fn(context: ArkUI_ContextHandle, option: *mut ArkUI_KeyframeAnimateOption) -> i32>

Sets the keyframe animation.

Arguments

context - Indicates a UIContext instance.

option - Indicates the keyframe animation parameters.

Returns

Returns the error code. Returns [ARKUI_ERROR_CODE_NO_ERROR] if the operation is successful. Returns [ARKUI_ERROR_CODE_PARAM_INVALID] if a parameter error occurs.

createAnimator: Option<unsafe extern "C" fn(context: ArkUI_ContextHandle, option: *mut ArkUI_AnimatorOption) -> ArkUI_AnimatorHandle>

Creates an animator object.

Arguments

context - Indicates a UIContext instance.

option - Indicates the animator parameters.

Returns

Returns the pointer to the animator object; returns NULL if a function parameter error occurs.

disposeAnimator: Option<unsafe extern "C" fn(animatorHandle: ArkUI_AnimatorHandle)>

Disposes of an animator object.

Arguments

animator - Indicates the target animator object.
