Interpolator
java.lang.Object | |
↳ | androidx.core.animation.AccelerateInterpolator |
An interpolator where the rate of change starts out slowly and and then accelerates.

Public constructors
AccelerateInterpolator
public AccelerateInterpolator ()
Creates a new instance of AccelerateInterpolator
with y=x^2 parabola.
AccelerateInterpolator
public AccelerateInterpolator (float factor)
Creates a new instance of AccelerateInterpolator
.
Parameters | |
---|---|
factor |
float : Degree to which the animation should be eased. Setting
factor to 1.0f produces a y=x^2 parabola. Increasing factor above
1.0f exaggerates the ease-in effect (i.e., it starts even
slower and ends evens faster)

AccelerateInterpolator
public AccelerateInterpolator (Context context, AttributeSet attrs)
Creates a new instance of AccelerateInterpolator
from XML.
Parameters | |
---|---|
context |
Context : The context. |
attrs |
AttributeSet : The AttributeSet from XML.

Public methods
getInterpolation
public float getInterpolation (float input)
Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction. This interpolated value is then multiplied by the change in value of an animation to derive the animated value at the current elapsed animation time.
Parameters | |
---|---|
input |
float : A value between 0 and 1.0 indicating our current point
in the animation where 0 represents the start and 1.0 represents
the endValue is between 0.0 and 1.0 inclusive. |
Returns | |
---|---|
float |
The interpolation value. This value can be more than 1.0 for
interpolators which overshoot their targets, or less than 0 for
interpolators that undershoot their targets.
Value is between 0.0 and 1.0 inclusive. |
