open class Transformation
kotlin.Any
   ↳ android.view.animation.Transformation

Defines the transformation to be applied at one point in time of an Animation.

Summary

Constants
static Int

Indicates a transformation that applies an alpha only (uses an identity matrix.)
static Int

Indicates a transformation that applies an alpha and a matrix.
static Int

Indicates a transformation that has no effect (alpha = 1 and identity matrix.)
static Int

Indicates a transformation that applies a matrix only (alpha = 1.)
Public constructors

Added in API level 1
Transformation()

Creates a new transformation with alpha = 1 and the identity matrix.

Public methods

clear

Added in API level 1
open fun clear(): Unit

Reset the transformation to a state that leaves the object being animated in an unmodified state. The transformation type is TYPE_BOTH by default.

compose

Added in API level 1
open fun compose(t: Transformation!): Unit

Apply this Transformation to an existing Transformation, e.g. apply a scale effect to something that has already been rotated.

Parameters
t Transformation!:

getAlpha

Added in API level 1
open fun getAlpha(): Float
Return
Float The degree of transparency

getMatrix

Added in API level 1
open fun getMatrix(): Matrix!
Return
Matrix! The 3x3 Matrix representing the transformation to apply to the coordinates of the object being animated

getTransformationType

Added in API level 1
open fun getTransformationType(): Int

Indicates the nature of this transformation.

Return
Int TYPE_ALPHA, TYPE_MATRIX, TYPE_BOTH or TYPE_IDENTITY.

set

Added in API level 1
open fun set(t: Transformation!): Unit

Parameters
t Transformation!: The transformation to clone.

setAlpha

Added in API level 1
open fun setAlpha(alpha: Float): Unit

Sets the degree of transparency

Parameters
alpha Float: 1.0 means fully opaque and 0.0 means fully transparent Value is between 0.0 and 1.0 inclusive

setTransformationType

Added in API level 1
open fun setTransformationType(transformationType: Int): Unit

Sets the transformation type.

Parameters
