I am getting this strange error on in onAttach(Context)

In onAttach function eclipse shows error stating

The method onAttach(Activity) in the type Fragment is not applicable for the arguments (Context)

although it is clearly Context type variable passed

import android.content.Context;

public class MyListFragment extends Fragment{
    private OnItemSelectedListener listener;

      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container,
          Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_rsslist_overview,
            container, false);
        Button button = (Button) view.findViewById(R.id.button1);
        button.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
            updateDetail("fake");
          }
        });
        return view;
      }

      public interface OnItemSelectedListener {
        public void onRssItemSelected(String link);
      }

      @Override
      public void onAttach(Context context) {
        super.onAttach(context);
        if (context instanceof OnItemSelectedListener) {
          listener = (OnItemSelectedListener) context;
        } else {
          throw new ClassCastException(context.toString()
              + " must implemenet MyListFragment.OnItemSelectedListener");
        }
      }

      @Override
      public void onDetach() {
        super.onDetach();
        listener = null;
      }

      // may also be triggered from the Activity
      public void updateDetail(String uri) {
        // create a string just for testing
        String newTime = String.valueOf(System.currentTimeMillis());

        // inform the Activity about the change based
        // interface defintion
        listener.onRssItemSelected(newTime);
      }
}
