cl.arkui.1 Default Curve Parameter Change for Swiper Component

Access Level

Other

Reason for Change

Specification optimization.

Change Impact

When the curve parameter is not set for the Swiper component, the default curve changes from Linear to interpolatingSpring(-1,1,328,34).

API Level

Change Since

OpenHarmony SDK 5.0.0.16

Key API/Component Changes

Affected component: Swiper Before change: The default curve for Swiper was Linear. After change: The default curve for Swiper is interpolatingSpring(-1,1,328,34).

Example of Swiper Curve Change

Adaptation Guide

The default behavior has changed, no adaptation is needed, but you should ensure that the new default effect meets expectations. If it does not, custom modifications to the effect control variables should be made to achieve the desired outcome.

cl.arkui.2 Attribute Change When Component Size Is Not Set and Margin Exceeds Component Size

Access Level

Public API

Reason for Change

When the component’s width and height are not set and the margin exceeds the component’s size, it will compress the component’s size to zero.

Change Impact

This change is non-compatible.

Before the change in API version 12, when the component’s width and height were not set, and the set margin exceeded the component’s size, the compression did not take effect, and the component maintained its original size.

After the change in API version 12, when the component’s width and height are not set, and the set margin exceeds the component’s size, the compression takes effect, and the component’s width and height are compressed to zero.

Start API Level

Change Since

OpenHarmony SDK 5.0.0.16

Key API/Component Changes

Components with overly large margins

Adaptation Guide

Reduce the margin appropriately so that the component can be displayed, or set the width and height of the component so that its size is not affected by the margin.
