This subclass of `https://developer.android.com/reference/androidx/core/animation/ValueAnimator` provides support for animating properties on target objects. The constructors of this class take parameters to define the target object that will be animated as well as the name of the property that will be animated. Appropriate set/get functions are then determined internally and the animation will call these functions as necessary to animate the property.

ObjectAnimator supports the use of `https://developer.android.com/reference/androidx/core/animation/PropertyValuesHolder` and `https://developer.android.com/reference/androidx/core/animation/Keyframe` in resource files to create more complex animations. Using PropertyValuesHolders allows animators to animate several properties in parallel.

Using Keyframes allows animations to follow more complex paths from the start to the end values. Note that you can specify explicit fractional values (from 0 to 1) for each keyframe to determine when, in the overall duration, the animation should arrive at that value. Alternatively, you can leave the fractions off and the keyframes will be equally distributed within the total duration. Also, a keyframe with no value will derive its value from the target object when the animator starts, just like animators with only one value specified. In addition, an optional interpolator can be specified. The interpolator will be applied on the interval between the keyframe that the interpolator is set on and the previous keyframe. When no interpolator is supplied, the default `https://developer.android.com/reference/androidx/core/animation/AccelerateDecelerateInterpolator` will be used.

### Inherited Constants

From [androidx.core.animation.Animator](https://developer.android.com/reference/androidx/core/animation/Animator) `static final long` `https://developer.android.com/reference/androidx/core/animation/Animator#DURATION_INFINITE() = -1`

The value used to indicate infinite duration (e.g. when Animators repeat infinitely).
From [androidx.core.animation.ValueAnimator](https://developer.android.com/reference/androidx/core/animation/ValueAnimator) `static final int` `https://developer.android.com/reference/androidx/core/animation/ValueAnimator#INFINITE() = -1`

This value used used with the `https://developer.android.com/reference/androidx/core/animation/ValueAnimator#setRepeatCount(int)` property to repeat the animation indefinitely.
`static final int` `https://developer.android.com/reference/androidx/core/animation/ValueAnimator#RESTART() = 1`

When the animation reaches the end and `repeatCount` is INFINITE or a positive value, the animation restarts from the beginning.
`static final int` `https://developer.android.com/reference/androidx/core/animation/ValueAnimator#REVERSE() = 2`

When the animation reaches the end and `repeatCount` is INFINITE or a positive value, the animation reverses direction on every iteration.

### Inherited methods

## Public constructors

### ObjectAnimator

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/core#1.0.0)

```
public ObjectAnimator()
```

Creates a new ObjectAnimator object. This default constructor is primarily for use internally; the other constructors which take parameters are more generally useful.

## Public methods

### clone

```
public @NonNull ObjectAnimator clone()
```

### getNameForTrace

```
public @NonNull String getNameForTrace()
```

Returns the name of this animator for debugging purposes.

### getPropertyName

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/core#1.0.0)

```
public @NonNull String getPropertyName()
```

Gets the name of the property that will be animated. This name will be used to derive a setter function that will be called to set animated values. For example, a property name of `foo` will result in a call to the function `setFoo()` on the target object. If either `valueFrom` or `valueTo` is null, then a getter function will also be derived and called.

If this animator was created with a `https://developer.android.com/reference/android/util/Property.html` object instead of the string name of a property, then this method will return the `https://developer.android.com/reference/android/util/Property.html#getName()` of that Property object instead. If this animator was created with one or more `https://developer.android.com/reference/androidx/core/animation/PropertyValuesHolder` objects, then this method will return the `https://developer.android.com/reference/androidx/core/animation/PropertyValuesHolder#getPropertyName()` of that object (if there was just one) or a comma-separated list of all of the names (if there are more than one).

### getTarget

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/core#1.0.0)

```
public @Nullable Object getTarget()
```

The target object whose property will be animated by this animation

    @NonNull Object target,
    @NonNull String propertyName,
    @Nullable TypeConverter<PointF, @NonNull ?> converter,
    @NonNull Path path
)
```

Constructs and returns an ObjectAnimator that animates a property along a `Path`. A `Path` animation moves in two dimensions, animating coordinates `(x, y)` together to follow the line. This variant animates the coordinates in a `PointF` to follow the `Path`. If the `Property` associated with `propertyName` uses a type other than `PointF`, `converter` can be used to change from `PointF` to the type associated with the `Property`.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/java/lang/Object.html target` | The object whose property is to be animated. This object should have a public method on it called `setName()`, where `name` is the value of the `propertyName` parameter. |

```
public static @NonNull ObjectAnimator ofObject(
    @NonNull Object target,
    @NonNull String propertyName,
    @NonNull TypeEvaluator evaluator,
    @NonNull Object[] values
)
```

Constructs and returns an ObjectAnimator that animates between Object values. A single value implies that that value is the one being animated to, in which case the start value will be derived from the property being animated and the target object when `https://developer.android.com/reference/androidx/core/animation/ObjectAnimator#start()` is called for the first time. Two values imply starting and ending values. More than two values imply a starting value, values to animate through along the way, and an ending value (these values will be distributed evenly across the duration of the animation).

**Note:** The values are stored as references to the original objects, which means that changes to those objects after this method is called will affect the values on the animator. If the objects will be mutated externally after this method is called, callers should pass a copy of those objects instead.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/java/lang/Object.html target` | The object whose property is to be animated.

    @NonNull TypeEvaluator<V> evaluator,
    @NonNull V[] values
)
```

Constructs and returns an ObjectAnimator that animates between Object values. A single value implies that that value is the one being animated to, in which case the start value will be derived from the property being animated and the target object when `https://developer.android.com/reference/androidx/core/animation/ObjectAnimator#start()` is called for the first time. Two values imply starting and ending values. More than two values imply a starting value, values to animate through along the way, and an ending value (these values will be distributed evenly across the duration of the animation). This variant supplies a `TypeConverter` to convert from the animated values to the type of the property. If only one value is supplied, the `TypeConverter` must be a `https://developer.android.com/reference/androidx/core/animation/BidirectionalTypeConverter` to retrieve the current value.

**Note:** The values are stored as references to the original objects, which means that changes to those objects after this method is called will affect the values on the animator. If the objects will be mutated externally after this method is called, callers should pass a copy of those objects instead.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html T target` | The object whose property is to be animated. |
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/android/util/Property.html<T, P> property` | The property being animated. |

### ofPropertyValuesHolder

```
public static @NonNull ObjectAnimator ofPropertyValuesHolder(
    @NonNull Object target,
    @NonNull PropertyValuesHolder[] values
)
```

Constructs and returns an ObjectAnimator that animates between the sets of values specified in `PropertyValueHolder` objects. This variant should be used when animating several properties at once with the same ObjectAnimator, since PropertyValuesHolder allows you to associate a set of animation values with a property name.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/java/lang/Object.html target` | The object whose property is to be animated. Depending on how the PropertyValuesObjects were constructed, the target object should either have the `https://developer.android.com/reference/android/util/Property.html` objects used to construct the PropertyValuesHolder objects or (if the PropertyValuesHOlder objects were created with property names) the target object should have public methods on it called `setName()`, where `name` is the name of the property passed in as the `propertyName` parameter for each of the PropertyValuesHolder objects. |
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html PropertyValuesHolder[] values` | A set of PropertyValuesHolder objects whose values will be animated between over time. |

| Returns |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/androidx/core/animation/ObjectAnimator` | An ObjectAnimator object that is set up to animate between the given values. |

### setAutoCancel

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/core#1.0.0)

```
public void setAutoCancel(boolean cancel)
```

autoCancel controls whether an ObjectAnimator will be canceled automatically when any other ObjectAnimator with the same target and properties is started. Setting this flag may make it easier to run different animators on the same target object without having to keep track of whether there are conflicting animators that need to be manually canceled. Canceling animators must have the same exact set of target properties, in the same order.

| Parameters |
|---|---|
| `boolean cancel` | Whether future ObjectAnimators with the same target and properties as this ObjectAnimator will cause this ObjectAnimator to be canceled. |

### setDuration

```
public @NonNull ObjectAnimator setDuration(long duration)
```

Sets the length of the animation. The default duration is 300 milliseconds.

| Parameters |
|---|---|
| `long duration` | The length of the animation, in milliseconds. |

| Returns |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/androidx/core/animation/ObjectAnimator` | ObjectAnimator The object called with setDuration(). This return value makes it easier to compose statements together that construct and then set the duration, as in `ObjectAnimator.ofInt(target, propertyName, 0, 10).setDuration(500).start()`. |

### setFloatValues

```
public void setFloatValues(@NonNull float[] values)
```

Sets float values that will be animated between. A single value implies that that value is the one being animated to. However, this is not typically useful in a ValueAnimator object because there is no way for the object to determine the starting value for the animation (unlike ObjectAnimator, which can derive that value from the target object and property being animated). Therefore, there should typically be two or more values.

If there are already multiple sets of values defined for this ValueAnimator via more than one PropertyValuesHolder object, this method will set the values for the first of those objects.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html float[] values` | A set of values that the animation will animate between over time. |

### setIntValues

```
public void setIntValues(@NonNull int[] values)
```

Sets int values that will be animated between. A single value implies that that value is the one being animated to. However, this is not typically useful in a ValueAnimator object because there is no way for the object to determine the starting value for the animation (unlike ObjectAnimator, which can derive that value from the target object and property being animated). Therefore, there should typically be two or more values.

If there are already multiple sets of values defined for this ValueAnimator via more than one PropertyValuesHolder object, this method will set the values for the first of those objects.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html int[] values` | A set of values that the animation will animate between over time. |

### setObjectValues

```
public void setObjectValues(@NonNull Object[] values)
```

Sets the values to animate between for this animation. A single value implies that that value is the one being animated to. However, this is not typically useful in a ValueAnimator object because there is no way for the object to determine the starting value for the animation (unlike ObjectAnimator, which can derive that value from the target object and property being animated). Therefore, there should typically be two or more values.

**Note:** The Object values are stored as references to the original objects, which means that changes to those objects after this method is called will affect the values on the animator. If the objects will be mutated externally after this method is called, callers should pass a copy of those objects instead.

If there are already multiple sets of values defined for this ValueAnimator via more than one PropertyValuesHolder object, this method will set the values for the first of those objects.

There should be a TypeEvaluator set on the ValueAnimator that knows how to interpolate between these value objects. ValueAnimator only knows how to interpolate between the primitive types specified in the other setValues() methods.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html Object[] values` | The set of values to animate between. |

### setProperty

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/core#1.0.0)

```
public void setProperty(@NonNull Property property)
```

Sets the property that will be animated. Property objects will take precedence over properties specified by the `https://developer.android.com/reference/androidx/core/animation/ObjectAnimator#setPropertyName(java.lang.String)` method. Animations should be set up to use one or the other, not both.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/android/util/Property.html property` | The property being animated. Should not be null. |

### setPropertyName

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/core#1.0.0)

```
public void setPropertyName(@NonNull String propertyName)
```

Sets the name of the property that will be animated. This name is used to derive a setter function that will be called to set animated values. For example, a property name of `foo` will result in a call to the function `setFoo()` on the target object. If either `valueFrom` or `valueTo` is null, then a getter function will also be derived and called.

For best performance of the mechanism that calls the setter function determined by the name of the property being animated, use `float` or `int` typed values, and make the setter function for those properties have a `void` return value. This will cause the code to take an optimized path for these constrained circumstances. Other property types and return types will work, but will have more overhead in processing the requests due to normal reflection mechanisms.

Note that the setter function derived from this property name must take the same parameter type as the `valueFrom` and `valueTo` properties, otherwise the call to the setter function will fail.

If this ObjectAnimator has been set up to animate several properties together, using more than one PropertyValuesHolder objects, then setting the propertyName simply sets the propertyName in the first of those PropertyValuesHolder objects.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/java/lang/String.html propertyName` | The name of the property being animated. Should not be null. |

### setTarget

```
public void setTarget(@Nullable Object target)
```

Sets the target object whose property will be animated by this animation. Not all subclasses operate on target objects (for example, `https://developer.android.com/reference/androidx/core/animation/ValueAnimator`, but this method is on the superclass for the convenience of dealing generically with those subclasses that do handle targets.

**Note:** The target is stored as a weak reference internally to avoid leaking resources by having animators directly reference old targets. Therefore, you should ensure that animator targets always have a hard reference elsewhere.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/Nullable.html https://developer.android.com/reference/java/lang/Object.html target` | The object being animated |

### 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. A ValueAnimator object will ignore the request since it does not have enough information (such as a target object) to gather these values.

### 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. A ValueAnimator object will ignore the request since it does not have enough information (such as a target object) to gather these values.

### 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 `https://developer.android.com/reference/androidx/core/animation/Animator.AnimatorListener#onAnimationStart(androidx.core.animation.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.

### toString

```
public @NonNull String toString()
```
