Cloneable

直接已知子类:

AnimatorSet, ValueAnimator
```
public abstract class Animator
extends Object
implements Cloneable
```
This is the superclass for classes which provide basic support for animations which can be started, ended, and have AnimatorListeners added to them.

```
public Animator()
```
- 方法详细资料
  - start
```
public void start()
```
    Starts this animation. If the animation has a nonzero startDelay, the animation will start running after that delay elapses. A non-delayed animation will have its initial value(s) set immediately, followed by calls to Animator.AnimatorListener.onAnimationStart(Animator) for any listeners of this animator.
    The animation started by calling this method will be run on the thread that called this method. This thread should have a Looper on it (a runtime exception will be thrown if this is not the case). Also, if the animation will animate properties of objects in the view hierarchy, then the calling thread should be the UI thread for that view hierarchy.
  - cancel
```
public void cancel()
```
    Cancels the animation. Unlike end(), cancel() causes the animation to stop in its tracks, sending an Animator.AnimatorListener.onAnimationCancel(Animator) to its listeners, followed by an Animator.AnimatorListener.onAnimationEnd(Animator) message.
    This method must be called on the thread that is running the animation.
  - end
```
public void end()
```
    Ends the animation. This causes the animation to assign the end value of the property being animated, then calling the Animator.AnimatorListener.onAnimationEnd(Animator) method on its listeners.
    This method must be called on the thread that is running the animation.
  - getStartDelay
```
public abstract long getStartDelay()
```
    The amount of time, in milliseconds, to delay starting the animation after start() is called.
    
    返回:
    
    the number of milliseconds to delay running the animation
  - setStartDelay
```
public abstract void setStartDelay(long startDelay)
```
    The amount of time, in milliseconds, to delay starting the animation after start() is called.
    
    参数:
    
    startDelay - The amount of the delay, in milliseconds
  - setDuration
```
public abstract Animator setDuration(long duration)
```
    Sets the length of the animation.
    
    参数:
    
    duration - The length of the animation, in milliseconds.
  - getDuration
```
public abstract long getDuration()
```
    Gets the length of the animation.
    
    返回:
    
    The length of the animation, in milliseconds.
  - setInterpolator
```
public abstract void setInterpolator(android.view.animation.Interpolator value)
```
    The time interpolator used in calculating the elapsed fraction of this animation. The interpolator determines whether the animation runs with linear or non-linear motion, such as acceleration and deceleration. The default value is AccelerateDecelerateInterpolator
    
    参数:
    
    value - the interpolator to be used by this animation
  - isRunning
```
public abstract boolean isRunning()
```
    Returns whether this Animator is currently running (having been started and gone past any initial startDelay period and not yet ended).
    
    返回:
    
    Whether the Animator is running.
  - isStarted
```
public boolean isStarted()
```
    Returns whether this Animator has been started and not yet ended. This state is a superset of the state of isRunning(), because an Animator with a nonzero startDelay will return true for isStarted() during the delay phase, whereas isRunning() will return true only after the delay phase is complete.
    
    返回:
    
    Whether the Animator has been started and not yet ended.
  - addListener
```
public void addListener(Animator.AnimatorListener listener)
```
    Adds a listener to the set of listeners that are sent events through the life of an animation, such as start, repeat, and end.
    
    参数:
    
    listener - the listener to be added to the current set of listeners for this animation.
  - removeListener
```
public void removeListener(Animator.AnimatorListener listener)
```
    Removes a listener from the set listening to this animation.
    
    参数:
    
    listener - the listener to be removed from the current set of listeners for this animation.
  - getListeners
```
public ArrayList<Animator.AnimatorListener> getListeners()
```
    Gets the set of Animator.AnimatorListener objects that are currently listening for events on this Animator object.
    
    返回:
    
    ArrayList The set of listeners.
  - removeAllListeners
```
public void removeAllListeners()
```
    Removes all listeners from this object. This is equivalent to calling getListeners() followed by calling clear() on the returned list of listeners.
  - clone
```
public Animator clone()
```
    覆盖:
    
    clone 在类中 Object
  - setupStartValues
```
public void setupStartValues()
```
    This method tells the object to use appropriate information to extract starting values for the animation. For example, a AnimatorSet object will pass this call to its child objects to tell them to set up the values. A ObjectAnimator object will use the information it has about its target object and PropertyValuesHolder objects to get the start values for its properties. An ValueAnimator object will ignore the request since it does not have enough information (such as a target object) to gather these values.
  - setupEndValues
```
public void setupEndValues()
```
    This method tells the object to use appropriate information to extract ending values for the animation. For example, a AnimatorSet object will pass this call to its child objects to tell them to set up the values. A ObjectAnimator object will use the information it has about its target object and PropertyValuesHolder objects to get the start values for its properties. An ValueAnimator object will ignore the request since it does not have enough information (such as a target object) to gather these values.
  - setTarget
```
public void setTarget(Object target)
```
    Sets the target object whose property will be animated by this animation. Not all subclasses operate on target objects (for example, ValueAnimator, but this method is on the superclass for the convenience of dealing generically with those subclasses that do handle targets.
    
    参数:
    
    target - The object being animated
