方法详细资料

create

public static android.view.animation.Interpolator create(android.graphics.Path path)

Create an Interpolator for an arbitrary Path. The Path must begin at (0, 0) and end at (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.

参数:

path - the Path to use to make the line representing the Interpolator

返回:

the Interpolator representing the Path

create

public static android.view.animation.Interpolator create(float controlX,
                                                         float controlY)

Create an Interpolator for a quadratic Bezier curve. The end points (0, 0) and (1, 1) are assumed.

参数:

controlX - the x coordinate of the quadratic Bezier control point

controlY - the y coordinate of the quadratic Bezier control point

返回:

the Interpolator representing the quadratic Bezier curve

create

public static android.view.animation.Interpolator create(float controlX1,
                                                         float controlY1,
                                                         float controlX2,
                                                         float controlY2)

Create an Interpolator for a cubic Bezier curve. The end points (0, 0) and (1, 1) are assumed.

参数:

controlX1 - the x coordinate of the first control point of the cubic Bezier

controlY1 - the y coordinate of the first control point of the cubic Bezier

controlX2 - the x coordinate of the second control point of the cubic Bezier

controlY2 - the y coordinate of the second control point of the cubic Bezier

返回:

the Interpolator representing the cubic Bezier curve
