Adapted from link Naveen mentioned, works using only native Android classes:

public class ColorUtils {

    /**
     * Initialize the color list that we have.
     */
    private ArrayList<ColorName> initColorList() {
        ArrayList<ColorName> colorList = new ArrayList<ColorName>();
        colorList.add(new ColorName("AliceBlue", 0xF0, 0xF8, 0xFF));

Example usage:

 String black = new ColorUtils().getColorNameFromHex("#000000");

Answer 2

Try this way,hope this will help you to solve your problem.

Define your custom HashMap to hold color name and color code Like :

Set/Get Color Name : HashMap colorNameMap = new HashMap(); colorNameMap.put("#000000","black");

String colorName = colorNameMap.get("#000000");

Set/Get Color Code :

HashMap<String,String> colorCodeMap = new HashMap<String, String>();
olorNameMap.put("black","#000000");

String colorCode = colorNameMap.get("black");

Answer 3

you need to do that manually by mapping color code to its Name by creating simple HashMap object and map color code with specific names.you can get few color with names here

+1 for code in above comment its using same colors as Link content lists
