To reference an Android color resource in an XML layout simple use the same way other resources are referenced, such as strings: Accessing Android System Color ResourcesДЄre there predefined colors in Android? Yes, there are existing color resources, but not many.

Then just use them as required: findViewById(R.id.textView1).setBackgroundColor(getResources().getColor(R.color.Purple)) Referencing Colors in Android XML Layouts Here is a resource file to use the HTML/CSS color names in Android code: A resource file can be created to define the common colors for an app. CSS colors, or X Window System and SVG color names). The use of a named color in a resource file is handy when dealing with common colors (such as the standard HTML named web colors, i.e. Though for clarity and future maintenance it is wise to be explicit and always define all four parts of an Android color: #00FF00 If the color is solid (full alpha value) then the color resource can leave the alpha value out. Use getColor() to read the color value from the resource: int lime=getResources().getColor(R.color.Lime) ДЇindViewById(R.id.textView1).setBackgroundColor(lime) A color resource does not need to be stored in colors.xml, other file names can be used.) Then use the File or context menu, usually right-click, then the New option and select Android resource file. (Note: To add a new resource first select the app in the Project explorer file. In colors.xml add a definition for the required color, Lime is defined here as an example: In the Android Studio project there should be a colors.xml file in the res/values folder. Either open an existing resource file or create a new one. To help with handling colors in Android they can be made into a resource for easy reuse.

When entering code in Studio add import statements when prompted by pressing Alt-Enter.)
