I want to store the colors I use in the colors.xml file. In addition to using them in an xml-layout, I also want to use these colors in my Java code, when drawing things to the Canvas.

The thing is, I am not always using the colors in a class that extends Application. For example, I have classes for objects that get drawn to the Canvas.

The thing is, I don’t want to store the context in each class that needs access to my resources file.

My current solution is the following:

colors.xml

<?xml version="1.0" encoding="utf-8"?> <resources>     <color name="colorOne">#123456</color> </resources> 

A static class called Attributes for constants, including colors:

public class Attributes {     private static final Resources RESOURCES = MainActivity.getContext().getResources();      public static final int ONE_COLOR = RESOURCES.getColor(R.color.colorOne);     public static final int SOME_OTHER_CONSTANT = 1; } 

MainActivity:

public class MainActivity extends Activity {      private static Context context;      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         this.context = getApplicationContext();      @Override     protected void onPause() {         super.onPause();     }      @Override     protected void onResume() {         super.onResume();     }      public static Context getContext() {         return context;     } } 

And, finally in my object class:

public class ScreenArea {     private Rect area;     private Paint paint;      public ScreenArea(Rect area) {         this.area = area;         paint = new Paint();         paint.setColor(Attributes.COLOR_ONE);     }      public void draw(Canvas canvas) {         canvas.drawRect(area, paint);     } } 

Okay, so first of all, this works. But, I am wondering if this is the right way to go. I have been reading about the Singleton class, but most examples are very basic an not focusing on storing constants, like I am doing right now.

So my questions:

• Is this the right way to go or should I implement a Singleton?
• If so, who can point me in the right direction?
