PathInterpolatorCompat
class PathInterpolatorCompat
Helper for creating path-based Interpolator instances. On API 21 or newer, the platform implementation will be used and on older platforms a compatible alternative implementation will be used.
Summary
Public methods
create
static fun create(path: Path!): Interpolator!
Create an Interpolator for an arbitrary . The must begin at (0, 0) and end at (1, 1). The x-coordinate along the 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.
create
static fun create(
controlX: Float,
controlY: Float
): Interpolator!
Create an Interpolator 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 |
create
static fun create(
controlX1: Float,
controlY1: Float,
controlX2: Float,
controlY2: Float
): Interpolator!
Create an Interpolator 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 |
