# PathInterpolatorCompat added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) belongs to Maven artifact com.android.support:support-compat:28.0.0-alpha1 Summary:[Methods](https://developer.android.com/reference/android/support/v4/view/animation/PathInterpolatorCompat#pubmethods)\|[Inherited Methods](https://developer.android.com/reference/android/support/v4/view/animation/PathInterpolatorCompat#inhmethods)\|[\[Expand All\]](https://developer.android.com/reference/android/support/v4/view/animation/PathInterpolatorCompat#) # PathInterpolatorCompat | This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). ` public final class PathInterpolatorCompat ` ` extends Object `` ` |---|----------------------------------------------------------| | java.lang.Object || | ↳ | android.support.v4.view.animation.PathInterpolatorCompat |
*** ** * ** *** Helper for creating path-based[Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html)instances.

The[Path](https://developer.android.com/reference/android/graphics/Path.html)must begin at`(0, 0)`and end at`(1, 1)`. The x-coordinate along the[Path](https://developer.android.com/reference/android/graphics/Path.html)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](https://developer.android.com/reference/android/graphics/Path.html)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.

| Parameters || |--------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `path` | `Path`: the[Path](https://developer.android.com/reference/android/graphics/Path.html)to use to make the line representing the[Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html)
| | Returns || |--------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html) | the[Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html)representing the[Path](https://developer.android.com/reference/android/graphics/Path.html)
| ### create added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` Interpolator create (float controlX1, float controlY1, float controlX2, float controlY2) ``` Create an[Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html)for a cubic Bezier curve. The end points`(0, 0)`and`(1, 1)`are assumed.
| Parameters || |-------------|----------------------------------------------------------------------------------| | `controlX1` | `float`: the x coordinate of the first control point of the cubic Bezier
| | `controlY1` | `float`: the y coordinate of the first control point of the cubic Bezier
| | `controlX2` | `float`: the x coordinate of the second control point of the cubic Bezier
| | `controlY2` | `float`: the y coordinate of the second control point of the cubic Bezier
| | Returns || |--------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------| | [Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html) | the[Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html)representing the cubic Bezier curve
| ### create added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` Interpolator create (float controlX, float controlY) ``` Create an[Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html)for a quadratic Bezier curve. The end points`(0, 0)`and`(1, 1)`are assumed.
| Parameters || |------------|------------------------------------------------------------------------| | `controlX` | `float`: the x coordinate of the quadratic Bezier control point
| | `controlY` | `float`: the y coordinate of the quadratic Bezier control point
| | Returns || |--------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------| | [Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html) | the[Interpolator](https://developer.android.com/reference/android/view/animation/Interpolator.html)representing the quadratic Bezier curve
