构造器详细资料

AnimatorGroup

public AnimatorGroup()

Default constructor used to create an animator group.

方法详细资料

runParallel

public void runParallel(Animator... items)

Specifies a group of animations that are played in parallel. Calling this method will clear previously added animations.

参数:

items - Specifies a group of animations that are played in parallel.

从以下版本开始:

4

runSerially

public void runSerially(Animator... items)

Specifies a group of animations that are played in series. Calling this method will clear previously added animations.

参数:

items - Specifies a group of animations that are played in series.

从以下版本开始:

getRoundCount

public int getRoundCount()

Obtains the total rounds of animator groups. A group of animations that are played in parallel is regarded as a round.

getAnimatorsAt

public ArrayList<Animator> getAnimatorsAt(int round)

Obtains animators used in a round of an animator group.

参数:

round - Specifies the index (starting from 0) of animations in an animator group.

返回:

Returns a group of animations that are played in parallel.

clear

public void clear()

Clears the animations in an animator group.

build

public AnimatorGroup.Builder build()

Obtains a builder that assists in creating an animator group, calling this method will clear previously added animations.

返回:

Returns the builder of the current animator group. Each animator group has only one builder.

setDuration

public void setDuration(long duration)

Sets the duration of an animator group. The specified time applies to all animations in the animator group. If no value is specified, the getDuration method in AnimatorGroup will return -1.

参数:

duration - Specifies the duration for animations in an animator group. The value must be greater than or equal to 0, in unit of milliseconds.

setDelay

public void setDelay(long startDelay)

Sets the startup delay of an animator group. The startup delay is applicable only to the first round.

参数:

startDelay - Specifies the startup delay for animations in an animator group. The value must be greater than or equal to 0, in unit of milliseconds.

setLoopedCount

public void setLoopedCount(int loopedCount)

Sets the repetition times of an animator group. Repetition of an animator group means repeatedly calling the start function of animations in the group. The final animation effect depends on parameter configurations of animations in the group.

参数:

loopedCount - Specifies the repetition times of animations in an animator group. The value must be greater than or equal to 0, or INFINITE. If the value is 0, the animation will be played only once.

setCurveType

public void setCurveType(int curveType)

Sets an curveType used by an animator group. The specified curveType applies to all animations in the animator group. If no value is specified, the getCurveType method in AnimatorGroup will return -1. For details, see Animator.CurveType.INVALID.

参数:

curveType - Specifies the curveType type.

setStateChangedListener

public void setStateChangedListener(Animator.StateChangedListener listener)

Sets the state changed listener for animator groups.

参数:

listener - Specifies the pause and resume listener for animator groups. You can set it to null to clear the existing listener.

setLoopedListener

public void setLoopedListener(Animator.LoopedListener listener)

Sets the repeat listener for animator groups.

参数:

listener - Specifies the repeat listener for animator groups. You can set it to null to clear the existing listener.

setCurve

public void setCurve(Animator.TimelineCurve curve)

Sets a timeline curve for all animations in this AnimatorGroup object.

参数:

curve - Indicates the curve to set.
