Question

I have two images in my drawable folder, one called “Red” and the other called “Yellow”. I am trying to set these images equal to two variables, one currently called “redchip” and the other called “yellowchip”. Both redchip and yellowchip are declared as integers.

Can I set the R.drawable image integer values equal to my variables, and if so, how?

Answer 1

What I have done in the past is use a map in a util class to return the drawable’s integer id.

Example:

public class DrawableUtil{
   public static final int KEY_CHIP_YELLOW = 0;
   public static final int KEY_CHIP_RED = 1;

   private Map<Integer, Integer> drawableMap = new HashMap<Integer, Integer>();

    DrawableUtil(){
        drawableMap.put(KEY_CHIP_YELLOW, R.drawable.yellowchip);
        drawableMap.put(KEY_CHIP_RED, R.drawable.redchip);
    }

    public int getYellowChip(){
        return drawableMap.get(KEY_CHIP_YELLOW);
    }
}
