Olá. Sou novo em desenvolvimento Android e estou com problema no código abaixo:

package br.com.tapanovisual.tvisual.fragments;

public class FragmentFavoritos extends Fragment {

//Dialog
private ProgressDialog pDialog;
//URL GET RESERVAS
private static String url = "http://tapanovisual.esy.es/selectUltimasReservas.php";

//JSON node Names
private static final String TAG_NAME = "nome";
private static final String TAG_RESERVAS = "estabelecimentos";

//JSONArray - Reservas
JSONArray JsonReservas = null;
//Hashmap para lista
ArrayList<HashMap<String, String>> reservaslist;

ListView lv;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_favoritos, container, false);

    reservaslist = new ArrayList<HashMap<String, String>>();
    final ListView lv = (ListView) view.findViewById(R.id.listAux);

    //Buscando Dados Bando de Dados
    new GetReservas().execute();

    return view;
}

class GetReservas extends AsyncTask<Void, Void, Void>{

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(getActivity());
        pDialog.setMessage("Carregando ultimas reservas...");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(false);
        pDialog.show();
    }

    @Override
    public Void doInBackground(Void...arg0) {

        //Criando Serviço Handler class Instacia
        ServiceHandler sh = new ServiceHandler();
        String jsonStr = sh.ServiceCall(url, ServiceHandler.GET);

        Log.d("Response: ", "> " + jsonStr);

        if(jsonStr != null){
            try {
                JSONObject JsonObj = new JSONObject(jsonStr);
                // Getting JSON Array node
                JsonReservas = JsonObj.getJSONArray(TAG_RESERVAS);

                //Looping all Reservas
                for (int i = 0; i < JsonReservas.length(); i++){

                    JSONObject c = JsonReservas.getJSONObject(i);
                    String nome = c.getString(TAG_NAME);

                    //HashMap para single reserva
                    HashMap<String, String> reserva = new HashMap<String, String>();
                    //Adicionando valor no HashMap
                    reserva.put(TAG_NAME, nome);

                    //Adicionando reserva na lista de reservas
                    reservaslist.add(reserva);

                }

            } catch (JSONException e) {
                e.printStackTrace();
            }
        }else{
            Log.e("ServiceHandler", "Não foi possivél encontrar dados na URL");
        }
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        super.onPostExecute(result);
        if(pDialog.isShowing()){
            pDialog.dismiss();
        }

        //Inserindo ParseJson na Lista
        ListAdapter adapter = new SimpleAdapter(getActivity(), reservaslist, R.layout.item_reserva, new String[]{TAG_NAME});
        lv.setAdapter(adapter);

    }
}

}

Quando eu faço:

ListAdapter adapter = new SimpleAdapter(getActivity(), reservaslist, R.layout.item_reserva, new String[]{TAG_NAME});

Dá erro no getActivity() da sintaxe acima. Estou desenvolvendo dentro de um Fragment e já tentei de tudo (Context)

Erro apresentado

Error:(147, 35) error: constructor SimpleAdapter in class SimpleAdapter cannot be applied to given types;
required: Context,List<? extends Map>,int,String[],int[]
found: FragmentActivity,ArrayList<HashMap<String,String>>,int,String[]
reason: actual and formal argument lists differ in length

Alguém conseguiria me ajudar?
Obrigado.
