I d like to use a color from an hexa string such as   FFFF0000  to  say  change the background color of a Layout  Color HSVToColor looks like a winner but it takes a float   as a parameter   Am I any close to the solution at all

This question comes up for a number of searches related to hex color so I will add a summary here  Color from int Hex colors take the form RRGGBB or AARRGGBB  alpha  red  green  blue   In my experience  when using an int directly  you need to use the full AARRGGBB form  If you only have the RRGGBB form then just prefix it with FF to make the alpha  transparency  fully opaque  Here is how you would set it in code  Using 0x at the beginning means it is hexadecimal and not base 10  int myColor   0xFF3F51B5  myView setBackgroundColor myColor    Color from String As others have noted  you can use Color parseColor like so int myColor   Color parseColor  quot  3F51B5 quot    myView setBackgroundColor myColor    Note that the String must start with a    Both RRGGBB and AARRGGBB formats are supported  Color from XML You should actually be getting your colors from XML whenever possible  This is the recommended option because it makes it much easier to make color changes to your app  If you set a lot of hex colors throughout your code then it is a big pain to try to change them later  Android material design has color palates with the hex values already configured   Material Design color styling Material Design color palette generator  These theme colors are used throughout your app and look like this  colors xml  lt  xml version  quot 1 0 quot  encoding  quot utf-8 quot   gt   lt resources gt     lt color name  quot primary quot  gt  3F51B5 lt  color gt     lt color name  quot primary dark quot  gt  303F9F lt  color gt     lt color name  quot primary light quot  gt  C5CAE9 lt  color gt     lt color name  quot accent quot  gt  FF4081 lt  color gt     lt color name  quot primary text quot  gt  212121 lt  color gt     lt color name  quot secondary text quot  gt  757575 lt  color gt     lt color name  quot icons quot  gt  FFFFFF lt  color gt     lt color name  quot divider quot  gt  BDBDBD lt  color gt   lt  resources gt   If you need additional colors  a good practice to follow is to define your color in two steps in xml  First name the the hex value color and then name a component of your app that should get a certain color  This makes it easy to adjust the colors later  Again  this is in colors xml   lt color name  quot orange quot  gt  fff3632b lt  color gt   lt color name  quot my view background color quot  gt  color orange lt  color gt   Then when you want to set the color in code  do the following  int myColor   ContextCompat getColor context  R color my view background color       myView setBackgroundColor myColor    Android Predefined colors The Color class comes with a number of predefined color constants  You can use it like this  int myColor   Color BLUE  myView setBackgroundColor myColor    Other colors are  Color BLACK Color BLUE Color CYAN Color DKGRAY Color GRAY Color GREEN Color LTGRAY Color MAGENTA Color RED Color TRANSPARENT Color WHITE Color YELLOW  Notes  A quick way to find hex colors is to open the color chooser dialog in Gimp  or some other photo editing software   Standard opacity levels in Material Design

I use this and it works great for me for setting any color I want   public static final int MY COLOR   Color rgb 255  102  153     Set the colors using 0-255 for each red  green and blue then anywhere you want that color used just put MY COLOR instead of Color BLUE or Color RED or any of the other static colors the Color class offers   Just do a Google search for color chart and it you can find a chart with the correct RGB codes using 0-255

Convert that string to an int color which can be used in setBackgroundColor and setTextColor  String string     FFFF0000   int color   Integer parseInt string replaceFirst           16     The 16 means it is hexadecimal and not your regular 0-9  The result should be the same as   int color   0xFFFF0000
