RadialGradient
public RadialGradient (float centerX, float centerY, float radius, int[] colors, float[] stops, Shader.TileMode tileMode)
Create a shader that draws a radial gradient given the center and radius.
Parameters | |
---|---|
centerX |
float : The x-coordinate of the center of the radius |
centerY |
float : The y-coordinate of the center of the radius |
radius |
float : Must be positive. The radius of the circle for this gradient. |
colors |
int : The sRGB colors to be distributed between the center and edge of the circle
This value cannot be null . |
stops |
float : May be null . Valid values are between 0.0f and
1.0f . The relative position of each corresponding color in
the colors array. If null , colors are distributed evenly
between the center and edge of the circle. |

centerY |
float : The y-coordinate of the center of the radius |
radius |
float : Must be positive. The radius of the circle for this gradient. |
colors |
long : The colors to be distributed between the center and edge of the circle
This value cannot be null . |
stops |
float : May be null . Valid values are between 0.0f and
1.0f . The relative position of each corresponding color in
the colors array. If null , colors are distributed evenly

Throws | |
---|---|
IllegalArgumentException |
if there are less than two colors, the colors do
not share the same ColorSpace or do not use a valid one, or stops
is not null and has a different length from colors . |
RadialGradient
public RadialGradient (float startX, float startY, float startRadius, float endX, float endY, float endRadius, long[] colors, float[] stops, Shader.TileMode tileMode)
Create a shader that draws a radial gradient given the start and end points as well as starting and ending radii. The starting point is often referred to as the focal center and represents the starting circle of the radial gradient.
Parameters | |
---|---|
startX |
float : The x-coordinate of the center of the starting circle of the radial gradient,
often referred to as the focal point. |
startY |
float : The y-coordinate of the center of the starting circle of the radial gradient,
often referred to as the focal point. |

float : The radius of the starting circle of the radial gradient, often referred
to as the focal radius. Must be greater than or equal to zero.
Value is 0.0f or greater |
endX |
float : The x-coordinate of the center of the radius for the end circle of the
radial gradient |
endY |
float : The y-coordinate of the center of the radius for the end circle of the
radial gradient |
endRadius |
float : The radius of the ending circle for this gradient. This must be strictly
greater than zero. A radius value equal to zero is not allowed.
Value is 0.0f or greater |
colors |
long : The colors to be distributed between the center and edge of the circle
This value cannot be null . |
stops |
float : May be null . Valid values are between 0.0f and
