PathInterpolator

Kotlin |Java

public class PathInterpolator
extends BaseInterpolator

java.lang.Object
↳	android.view.animation.BaseInterpolator
	↳	android.view.animation.PathInterpolator

An interpolator that can traverse a Path that extends from Point (0, 0) to (1, 1). The x coordinate along the Path is the input value and the output is the y coordinate of the line at that point. This means that the Path must conform to a function y = f(x).

The Path must not have gaps in the x direction and must not loop back on itself such that there can be two points sharing the same x coordinate. It is alright to have a disjoint line in the vertical direction:

     Path path = new Path();
     path.lineTo(0.25f, 0.25f);
     path.moveTo(0.25f, 0.5f);
     path.lineTo(1f, 1f);

Summary

Public constructors
`PathInterpolator(Context context, AttributeSet attrs)`
`PathInterpolator(Path path)` Create an interpolator for an arbitrary `Path`.
`PathInterpolator(float controlX, float controlY)` Create an interpolator for a quadratic Bezier curve.
`PathInterpolator(float controlX1, float controlY1, float controlX2, float controlY2)` Create an interpolator for a cubic Bezier curve.

Public methods
`float`	`getInterpolation(float t)` Using the line in the Path in this interpolator that can be described as `y = f(x)`, finds the y coordinate of the line given `t` as the x coordinate.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface


        
          android.animation.TimeInterpolator


      getInterpolation(float input)

Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction.
