AnimationSet
Animation set, which inherits from Animation.
Model restriction: This API can be used only in the stage model.
Atomic service API: This API can be used in atomic services since version 4.1.0(11).
System capability: SystemCapability.Map.Core
Since: 4.1.0(11)
[h2]constructor
constructor(shareInterpolator: boolean)
Constructor, which is used to construct an instance of the animation set.
This API inherits from the Animation method. The interpolator is shared only when shareInterpolator is set to true. Other attributes are not shared and cannot be set.
Model restriction: This API can be used only in the stage model.
Atomic service API: This API can be used in atomic services since version 4.1.0(11).
System capability: SystemCapability.Map.Core
Since: 4.1.0(11)
Parameters:
| Name | Type | Mandatory | Description |
|---|---|---|---|
| shareInterpolator | boolean | Yes | Indicates whether to share the interpolator. - true: yes - false: no |
Example:
// Create an alpha animation: from fully transparent (0.2) to fully opaque (1) let animation1: map.AlphaAnimation = new map.AlphaAnimation(0.2, 1); // Create a rotation animation: from 15 degrees to 150 degrees let animation2: map.RotateAnimation = new map.RotateAnimation(15, 150); // Create a scale animation: from the original size (1) to 3x scale let animation3: map.ScaleAnimation = new map.ScaleAnimation(1, 3, 1, 3); // Create an animation set. The value true indicates that only one animation is played at a time. let animation: map.AnimationSet = new map.AnimationSet(true); // Set the animation interpolator to linear (constant speed). animation.setInterpolator(Curve.Linear); // Add the preceding three animations to the animation set. animation.addAnimation(animation1); animation.addAnimation(animation2); animation.addAnimation(animation3); // Clear the animation set. animation.clearAnimation();
[h2]addAnimation
addAnimation(animation: Animation): void
Adds an animation.
Model restriction: This API can be used only in the stage model.
Atomic service API: This API can be used in atomic services since version 4.1.0(11).
System capability: SystemCapability.Map.Core
Since: 4.1.0(11)
Parameters:
| Name | Type | Mandatory | Description |
|---|---|---|---|
| animation | Animation | Yes | Animation object to be added. |
Example:
// Create an alpha animation: gradient from fully transparent (0.2) to fully opaque (1) let animation1: map.AlphaAnimation = new map.AlphaAnimation(0.2, 1); // Create a rotation animation: from 15 degrees to 150 degrees let animation2: map.RotateAnimation = new map.RotateAnimation(15, 150); // Create a scale animation: from original size (1,1) to (3,3) let animation3: map.ScaleAnimation = new map.ScaleAnimation(1, 3, 1, 3); // Create an animation set. The value true indicates that only one animation is played at a time (canceling the ongoing animation to play the next). let animation: map.AnimationSet = new map.AnimationSet(true); // Add the alpha animation to the animation set. animation.addAnimation(animation1); // Add the rotation animation to the animation set. animation.addAnimation(animation2); // Add the scale animation to the animation set. animation.addAnimation(animation3);
[h2]clearAnimation
clearAnimation(): void
Deletes animations.
