setImageResource from a string

I would like to change the imageview src based on my string, I have something like this:

ImageView imageView1 = (ImageView)findViewById(R.id.imageView1);

String correctAnswer = "poland";
String whatEver = R.drawable+correctAnswer;
imageView1.setImageResource(whatEver);


Of course it doesnt work. How can I change the image programmatically?

Answer
public static int getImageId(Context context, String imageName) {
    return context.getResources().getIdentifier("drawable/" + imageName, null, context.getPackageName());
}

use: imageView1.setImageResource(getImageId(this, correctAnswer);

Note: leave off the extension (eg, ".jpg").

Example: image is "abcd_36.jpg"

Context c = getApplicationContext();
int id = c.getResources().getIdentifier("drawable/"+"abcd_36", null, c.getPackageName());
((ImageView)v.findViewById(R.id.your_image_on_your_layout)).setImageResource(id);
