Color

public class Color
extends Object

java.lang.Object
   ↳ android.graphics.Color


The Color class defines methods for creating and converting color ints. Colors are represented as packed ints, made up of 4 bytes: alpha, red, green, blue. The values are unpremultiplied, meaning any transparency is stored solely in the alpha component, and not in the color components. The components are stored as follows (alpha << 24) | (red << 16) | (green << 8) | blue. Each component ranges between 0..255 with 0 meaning no contribution for that component, and 255 meaning 100% contribution. Thus opaque-black would be 0xFF000000 (100% opaque but no contributions from red, green, or blue), and opaque-white would be 0xFFFFFFFF

Public methods

HSVToColor

Added in API level 1
int HSVToColor (float[] hsv)

Convert HSV components to an ARGB color. Alpha set to 0xFF. hsv[0] is Hue [0 .. 360) hsv[1] is Saturation [0...1] hsv[2] is Value [0...1] If hsv values are out of range, they are pinned.

Parameters
hsv float: 3 element array which holds the input HSV components.
Returns
int the resulting argb color

HSVToColor

Added in API level 1
int HSVToColor (int alpha, 
                float[] hsv)

Convert HSV components to an ARGB color. The alpha component is passed through unchanged. hsv[0] is Hue [0 .. 360) hsv[1] is Saturation [0...1] hsv[2] is Value [0...1] If hsv values are out of range, they are pinned.

Parameters
alpha int: the alpha component of the returned argb color.
hsv float: 3 element array which holds the input HSV components.
Returns
int the resulting argb color

RGBToHSV

Added in API level 1
void RGBToHSV (int red, 
                int green, 
                int blue, 
                float[] hsv)

Convert RGB components to HSV. hsv[0] is Hue [0 .. 360) hsv[1] is Saturation [0...1] hsv[2] is Value [0...1]

Parameters
red int: red component value [0..255]
green int: green component value [0..255]
blue int: blue component value [0..255]
hsv float: 3 element array which holds the resulting HSV components.

alpha

Added in API level 1
int alpha (int color)

Return the alpha component of a color int. This is the same as saying color >>> 24

Parameters
color int
Returns
int

argb

Added in API level 1
int argb (int alpha, 
                int red, 
                int green, 
                int blue)

Return a color-int from alpha, red, green, blue components. These component values should be [0..255], but there is no range check performed, so if they are out of range, the returned color is undefined.

Parameters
alpha int: Alpha component [0..255] of the color
red int: Red component [0..255] of the color
green int: Green component [0..255] of the color
blue int: Blue component [0..255] of the color
Returns
int

blue

Added in API level 1
int blue (int color)

Return the blue component of a color int. This is the same as saying color & 0xFF

Parameters
color int
Returns
int

colorToHSV

Added in API level 1
void colorToHSV (int color, 
                float[] hsv)

Convert the argb color to its HSV components. hsv[0] is Hue [0 .. 360) hsv[1] is Saturation [0...1] hsv[2] is Value [0...1]

Parameters
color int: the argb color to convert. The alpha component is ignored.
hsv float: 3 element array which holds the resulting HSV components.

green

Added in API level 1
int green (int color)

Return the green component of a color int. This is the same as saying (color >> 8) & 0xFF

Parameters
color int
Returns
int

parseColor

Added in API level 1
int parseColor (String colorString)

Parse the color string, and return the corresponding color-int. If the string cannot be parsed, throws an IllegalArgumentException exception. Supported formats are: #RRGGBB #AARRGGBB or one of the following names: 'red', 'blue', 'green', 'black', 'white', 'gray', 'cyan', 'magenta', 'yellow', 'lightgray', 'darkgray', 'grey', 'lightgrey', 'darkgrey', 'aqua', 'fuchsia', 'lime', 'maroon', 'navy', 'olive', 'purple', 'silver', 'teal'.

Parameters
colorString String
Returns
int

red

Added in API level 1
int red (int color)

Return the red component of a color int. This is the same as saying (color >> 16) & 0xFF

Parameters
color int
Returns
int

rgb

Added in API level 1
int rgb (int red, 
                int green, 
                int blue)

Return a color-int from red, green, blue components. The alpha component is implicity 255 (fully opaque). These component values should be [0..255], but there is no range check performed, so if they are out of range, the returned color is undefined.

Parameters
red int: Red component [0..255] of the color
green int: Green component [0..255] of the color
blue int: Blue component [0..255] of the color
