Public methods
clone
open fun clone(): PropertyValuesHolder
Return | |
---|---|
PropertyValuesHolder |
a clone of this instance. |
Exceptions | |
---|---|
java.lang.CloneNotSupportedException |
if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned. |
getPropertyName
open fun getPropertyName(): String!
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.
ofFloat
open static fun ofFloat(
propertyName: String!,
vararg values: Float
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder with a given property name and set of float values.
Parameters | |
---|---|

open static fun ofInt(
propertyName: String!,
vararg values: Int
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder with a given property name and set of int values.

Parameters | |
---|---|
property |
Property<*, Int!>!: The property being animated. Should not be null. |
values |
Int: The values that the property will animate between. |
Return | |
---|---|
PropertyValuesHolder! |
PropertyValuesHolder The constructed PropertyValuesHolder object. |
ofKeyframe
open static fun ofKeyframe(
propertyName: String!,
vararg values: Keyframe!
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder object with the specified property name and set of values. These values can be of any type, but the type should be consistent so that an appropriate android.animation.TypeEvaluator
can be found that matches the common type.
If there is only one value, it is assumed to be the end value of an animation, and an initial value will be derived, if possible, by calling a getter function on the object. Also, if any value is null, the value will be filled in when the animation starts in the same way. This mechanism of automatically getting null values only works if the PropertyValuesHolder object is used in conjunction ObjectAnimator
, and with a getter function derived automatically from propertyName
, since otherwise PropertyValuesHolder has no way of determining what the value should be.
Parameters | |
---|---|
propertyName |
String!: The name of the property associated with this set of values. This can be the actual property name to be used when using a ObjectAnimator object, or just a name used to get animated values, such as if this object is used with an ValueAnimator object. |
values |
Keyframe!: The set of values to animate between. |
ofKeyframe
open static fun ofKeyframe(
property: Property<Any!, Any!>!,
vararg values: Keyframe!
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder object with the specified property and set of values. These values can be of any type, but the type should be consistent so that an appropriate android.animation.TypeEvaluator
can be found that matches the common type.
If there is only one value, it is assumed to be the end value of an animation, and an initial value will be derived, if possible, by calling the property's android.util.Property#get(Object)
function. Also, if any value is null, the value will be filled in when the animation starts in the same way. This mechanism of automatically getting null values only works if the PropertyValuesHolder object is used in conjunction with ObjectAnimator
, since otherwise PropertyValuesHolder has no way of determining what the value should be.

ofObject
open static fun ofObject(
propertyName: String!,
evaluator: TypeEvaluator<Any!>!,
vararg values: Any!
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder with a given property name and set of Object values. This variant also takes a TypeEvaluator because the system cannot automatically interpolate between objects of unknown type.
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 PropertyValuesHolder. If the objects will be mutated externally after this method is called, callers should pass a copy of those objects instead.
Parameters | |
---|---|

Return | |
---|---|
PropertyValuesHolder! |
PropertyValuesHolder The constructed PropertyValuesHolder object. |
ofObject
open static fun ofObject(
propertyName: String!,
converter: TypeConverter<PointF!, *>!,
path: Path!
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder with a given property name and a Path along which the values should be animated. This variant supports a TypeConverter
to convert from PointF
to the target type.
The PointF passed to converter
or property
, if converter
is null
, is reused on each animation frame and should not be stored by the setter or TypeConverter.
Parameters | |
---|---|

ofObject
@SafeVarargs open static fun <V : Any!> ofObject(
property: Property<Any!, Any!>!,
evaluator: TypeEvaluator<V>!,
vararg values: V
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder with a given property and set of Object values. This variant also takes a TypeEvaluator because the system cannot automatically interpolate between objects of unknown type.
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 PropertyValuesHolder. If the objects will be mutated externally after this method is called, callers should pass a copy of those objects instead.
Parameters | |
---|---|
property |
Property<Any!, Any!>!: The property being animated. Should not be null. |

property: Property<*, V>!,
converter: TypeConverter<T, V>!,
evaluator: TypeEvaluator<T>!,
vararg values: T
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder with a given property and set of Object values. This variant also takes a TypeEvaluator because the system cannot automatically interpolate between objects of unknown type. This variant also takes a TypeConverter
to convert from animated values to the type of the property. If only one value is supplied, the TypeConverter
must be a android.animation.BidirectionalTypeConverter
to retrieve the current value.
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 PropertyValuesHolder. If the objects will be mutated externally after this method is called, callers should pass a copy of those objects instead.
Parameters | |
---|---|
property |
Property<*, V>!: The property being animated. Should not be null. |
converter |
TypeConverter<T, V>!: Converts the animated object to the Property type. |
evaluator |
TypeEvaluator<T>!: A TypeEvaluator that will be called on each animation frame to provide the necessary interpolation between the Object values to derive the animated value. |
values |
T: The values that the property will animate between. |
Return | |
---|---|
PropertyValuesHolder! |
PropertyValuesHolder The constructed PropertyValuesHolder object. |
ofObject
open static fun <V : Any!> ofObject(
property: Property<*, V>!,
converter: TypeConverter<PointF!, V>!,
path: Path!
): PropertyValuesHolder!
Constructs and returns a PropertyValuesHolder with a given property and a Path along which the values should be animated. This variant supports a TypeConverter
to convert from PointF
to the target type.
The PointF passed to converter
or property
, if converter
is null
, is reused on each animation frame and should not be stored by the setter or TypeConverter.
Parameters | |
---|---|
property |
Property<*, V>!: The property being animated. Should not be null. |
converter |
TypeConverter<PointF!, V>!: Converts a PointF to the type associated with the setter. May be null if conversion is unnecessary. |

---|---|
PropertyValuesHolder! |
PropertyValuesHolder The constructed PropertyValuesHolder object. |
setConverter
open fun setConverter(converter: TypeConverter<Any!, Any!>!): Unit
Sets the converter to convert from the values type to the setter's parameter type. If only one value is supplied, converter must be a android.animation.BidirectionalTypeConverter
.
Parameters | |
---|---|
converter |
TypeConverter<Any!, Any!>!: The converter to use to convert values. |
setEvaluator
open fun setEvaluator(evaluator: TypeEvaluator<Any!>!): Unit
The TypeEvaluator will be automatically determined based on the type of values supplied to PropertyValuesHolder. The evaluator can be manually set, however, if so desired. This may be important in cases where either the type of the values supplied do not match the way that they should be interpolated between, or if the values are of a custom type or one not currently understood by the animation system. Currently, only values of type float and int (and their Object equivalents: Float and Integer) are correctly interpolated; all other types require setting a TypeEvaluator.
Parameters | |
---|---|
evaluator |
TypeEvaluator<Any!>!: |
setFloatValues
open fun setFloatValues(vararg values: Float): Unit
Set the animated values for this object to this set of floats. If there is only one value, it is assumed to be the end value of an animation, and an initial value will be derived, if possible, by calling a getter function on the object. Also, if any value is null, the value will be filled in when the animation starts in the same way. This mechanism of automatically getting null values only works if the PropertyValuesHolder object is used in conjunction ObjectAnimator
, and with a getter function derived automatically from propertyName
, since otherwise PropertyValuesHolder has no way of determining what the value should be.
Parameters | |
---|---|
values |
Float: One or more values that the animation will animate between. |
setIntValues
open fun setIntValues(vararg values: Int): Unit
Set the animated values for this object to this set of ints. If there is only one value, it is assumed to be the end value of an animation, and an initial value will be derived, if possible, by calling a getter function on the object. Also, if any value is null, the value will be filled in when the animation starts in the same way. This mechanism of automatically getting null values only works if the PropertyValuesHolder object is used in conjunction ObjectAnimator
, and with a getter function derived automatically from propertyName
, since otherwise PropertyValuesHolder has no way of determining what the value should be.
Parameters | |
---|---|
values |
Int: One or more values that the animation will animate between. |
setKeyframes
open fun setKeyframes(vararg values: Keyframe!): Unit
Set the animated values for this object to this set of Keyframes.
Parameters | |
---|---|
values |
Keyframe!: One or more values that the animation will animate between. |
setObjectValues
open fun setObjectValues(vararg values: Any!): Unit
Set the animated values for this object to this set of Objects. If there is only one value, it is assumed to be the end value of an animation, and an initial value will be derived, if possible, by calling a getter function on the object. Also, if any value is null, the value will be filled in when the animation starts in the same way. This mechanism of automatically getting null values only works if the PropertyValuesHolder object is used in conjunction ObjectAnimator
, and with a getter function derived automatically from propertyName
, since otherwise PropertyValuesHolder has no way of determining what the value should be.
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 PropertyValuesHolder. If the objects will be mutated externally after this method is called, callers should pass a copy of those objects instead.
Parameters | |
---|---|
values |
Any!: One or more values that the animation will animate between. |
setProperty
open fun setProperty(property: Property<Any!, Any!>!): Unit
Sets the property that will be animated.
Note that if this PropertyValuesHolder object is used with ObjectAnimator, the property must exist on the target object specified in that ObjectAnimator.
Parameters | |
---|---|
property |
Property<Any!, Any!>!: The property being animated. |
setPropertyName
open fun setPropertyName(propertyName: String!): Unit
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.
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.
Parameters | |
---|---|
propertyName |
String!: The name of the property being animated. |
toString
open fun toString(): String
Return | |
---|---|
String |
a string representation of the object. |
