Java – How to reference a higher class in an anonymous class

I have this code :

public class Home extends Activity{

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
            //...
            at some point I have
            s.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){

@Override
              public void onProgressChanged(SeekBar seekBar, int progress,
                      boolean fromUser) {

ContextNotionLevel ctnl=new ContextNotionLevel(this);
 <-- how can I reference Home class here to replace **this**, which as it is points to OnSeekBarChangeListener
              }
    }
}

You can try:

 ContextNotionLevel ctnl=new ContextNotionLevel(Home.this);
