Получать Арраи Лист из-за AsyncTask одной унифицированный указатель ресурса

Я пробую извлекать список array из-за asynctask одной url но мне не удается завершить действие.

Это ошибка:

Ошибка: (35, 22) ошибка: несовместимый types required: ArrayList found: ArrayList

Ошибка: (34, 25) ошибка: несовместимый types required: Activity found: Context

Выполни:

  new List_URL().execute();



    ListView lvDiversos = (ListView) findViewById(R.id.lista_notificaciones);


    public class List_URL extends AsyncTask<ArrayList, ProgressBar, ArrayList<HttpHandler2>> {

                }

            } catch (Exception e) {
                //Si se produce un error, lo mostramos

            lvDiversos.setAdapter(cityAdapter);



        }
    }

Мой HttpHandler2:

public class HttpHandler2 {
  protected int id;
  protected String id_pedido;
  protected String msg;
  protected String user;
  protected String gcmpartner;
  protected String id_partner;
  protected String date;


  public HttpHandler2(int id, String id_pedido, String user, String gcmpartner, String id_partner, String msg, String date) {
    this.id = id;
    this.id_pedido = id_pedido;
    this.msg = msg;
    this.user = user;
    this.gcmpartner = gcmpartner;
    this.id_partner = id_partner;
    this.date = date;
  }


  /////////////////////id////////////////////

  public int getId() {return id;}

  public void setId(int id) { this.id = id;}







  //////////////////////////////ID_PEDIDO/////////////////////////
  public String getid_pedido() {
    return id_pedido;
  }

  public void setid_pedido(String id_pedido) {
    this.id_pedido = id_pedido;
  }







  //////////////////////////////MSG/////////////////////////
  public String getmsg() {return msg;}

  public void setmsg(String msg) {

  }







  //////////////////////////////USER/////////////////////////

  public void setuser(String user) {

Уже я остаюсь в конце концов таким образом:

В моей главной активности:

ArrayList<HttpHandler2> diversosAvaiable = new ArrayList<HttpHandler2>();

В моем Основании Adapter:

        gn.setCornerRadius(24);


         /*COLORES*/






        if (city.getuser().equals("admin")){

         LinearLayout mensages=(LinearLayout)vi.findViewById(R.id.ESTILOS_RESULTADOS);
         mensages.setGravity(Gravity.LEFT);
         user.setBackgroundDrawable(gd);
         user.setTextColor(msg.getContext().getResources().getColor(R.color.black));
         msg.setTextColor(msg.getContext().getResources().getColor(R.color.gray));







        } else if (city.getuser().equals("user")){


            LinearLayout mensages=(LinearLayout)vi.findViewById(R.id.ESTILOS_RESULTADOS);

         msg.setTextColor(msg.getContext().getResources().getColor(R.color.gray));

        }


        /*

        } else{

            msg.setTextAppearance(context, R.style.user);

        }

*/





        return vi;

    }



}

И HttpHandler2 ничего не изменил!

СПАСИБО!

Ошибка находится в этой части cГіdigo

SECUNDARIA.java

protected Activity activity;
protected ArrayList<HttpHandler2> items;
protected Activity context;

public SECUNDARIA(Context activity, ArrayList<String> items) {
    this.activity = activity;
    this.items = items;
}

Стоимость, которую ты назначаешь ему в переменные, которые ты признаешь дебетом, того, чтобы быть того же типа, а именно:

protected Activity activity;
protected ArrayList<HttpHandler2> items;
protected Activity context;

public SECUNDARIA(Activity activity, ArrayList<HttpHandler2> items) {
    this.activity = activity;
    this.items = items;
}

или asГ-:

protected Context activity;
protected ArrayList<String> items;
protected Activity context;

public SECUNDARIA(Context activity, ArrayList<String> items) {
    this.activity = activity;
    this.items = items;
}
