类 AbilitySliceAnimator

java.lang.Object

ohos.aafwk.ability.AbilitySliceAnimator

public class AbilitySliceAnimator
extends Object

Customizes the transition animation between AbilitySlice instances.

You can set different parameters to implement different transition effects. Currently, only translate is supported. Rotate, alpha, and scale operations will be supported later.

The transition properties can be set by calling the onStart() method of the Ability. The default constructor is used to set the translation animation. To disable the transition animation, you can set the value of setAbilitySliceAnimator to null. Example code:

 protected void onStart(Intent intent) {
     setAbilitySliceAnimator(new AbilitySliceAnimator());
 }

AbilitySliceAnimator

public AbilitySliceAnimator()

A no-argument constructor used to enable right-to-left translation of ability slices.

AbilitySliceAnimator

public AbilitySliceAnimator(float fromX,
                            float fromY,
                            float toX,
                            float toY)

A parameterized constructor used to set the coordinates of the start and end positions for the translation.

The origin of coordinates is the upper-left corner on a screen. For example, if you move a view from (1080, 0) to (0, 0), the view is translated horizontally from right to left.

参数:

fromX - Indicates the X coordinate of the translation start position.

fromY - Indicates the Y coordinate of the translation start position.

toX - Indicates the X coordinate of the translation end position.

toY - Indicates the Y coordinate of the translation end position.
