How do I set background image with picasso in code

Question

I know picasso loads image into imageview etc but how do I set my layout background image using picasso?

My code:

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.relativelayout);
        relativeLayout.setBackgroundResource(R.drawable.table_background);
        Picasso.with(MainActivity.this)
                .load(R.drawable.table_background)
                .resize(200, 200)
                .into(relativeLayout);
        return relativeLayout;
    }

What I have here gives any error saying it cannot be resolved. I have a ScrollView and relative layouts.

Use callback of Picasso

    Picasso.with(getActivity()).load(R.drawable.table_background).into(new Target(){

  @Override
  public void onBitmapLoaded(Bitmap bitmap, LoadedFrom from) {
     mainLayout.setBackground(new BitmapDrawable(context.getResources(), bitmap));
  }

  @Override
  public void onBitmapFailed(final Drawable errorDrawable) {
      Log.d("TAG", "FAILED");
  }

  @Override
  public void onPrepareLoad(final Drawable placeHolderDrawable) {
      Log.d("TAG", "Prepare Load");
  }      
})
