LinearGradient

Added in API level 1
public LinearGradient (float x0, 
                float y0, 
                float x1, 
                float y1, 
                int[] colors, 
                float[] positions, 
                Shader.TileMode tile)

Create a shader that draws a linear gradient along a line.

Parameters
x0 float: The x-coordinate for the start of the gradient line

y0 float: The y-coordinate for the start of the gradient line

x1 float: The x-coordinate for the end of the gradient line

y1 float: The y-coordinate for the end of the gradient line

colors int: The sRGB colors to be distributed along the gradient line This value cannot be null.

positions float: May be null. The relative positions [0..1] of each corresponding color in the colors array. If this is null, the colors are distributed evenly along the gradient line.

tile Shader.TileMode: The Shader tiling mode This value cannot be null.

Added in API level 29
public LinearGradient (float x0, 
                float y0, 
                float x1, 
                float y1, 
                long[] colors, 
                float[] positions, 
                Shader.TileMode tile)

Create a shader that draws a linear gradient along a line.

Parameters
x0 float: The x-coordinate for the start of the gradient line

y0 float: The y-coordinate for the start of the gradient line

x1 float: The x-coordinate for the end of the gradient line

y1 float: The y-coordinate for the end of the gradient line

colors long: The colors to be distributed along the gradient line This value cannot be null.

positions float: May be null. The relative positions [0..1] of each corresponding color in the colors array. If this is null, the colors are distributed evenly along the gradient line.

tile Shader.TileMode: The Shader tiling mode This value cannot be null.

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 positions is not null and has a different length from colors.
