Android Color To Int conversion

Question

This might be a stupid question but I m surprised that Paint class has no setColor Color c  method  I want to do the following   public void setColor Color color              Paint p   new Paint    p setColor color      set color takes only int as a paramter                  So any easy way to convert Color to int

All the methods and variables in Color are static. You can not instantiate a Color object.

Official Color Docs

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

Paint DOES have set color function          Set the paint s color  Note that the color is an int containing alpha    as well as r g b  This 32bit value is not premultiplied  meaning that    its alpha can be any value  regardless of the values of r g b     See the Color class for more details         param color The new color  including alpha  to set in the paint      public native void setColor  ColorInt int color     As an Android developer  I set paint color like this     paint setColor getResources   getColor R color xxx      I define the color value on color xml something like      lt color name  xxx  gt  008fd2 lt  color gt    By the way if you want to the hex RGB value of specific color value  then you can check website like this  http   www rapidtables com web color RGB Color htm  I hope this helps   Enjoy coding
