리스트뷰 합 구하기에 대한 질문이 잇습니다.

Question

?

protected void onPostExecute(Object result)        {            int tsal = 0;            if(result != null)            {                                 ArrayList<frgDataList015> list = new ArrayList<frgDataList015>();                      frgAdapter015 adapter = new frgAdapter015(mainview.getContext(), R.layout.fragment015_sub1 , list);                                 try                {                    JSONArray ja = new JSONArray(result.toString());                                         for(int i = 0 ; i< ja.length(); i++)                    {                                                      JSONObject obj = ja.getJSONObject(i);                        list.add(new frgDataList015(obj.getString("appdate"), obj.getString("salamt"), obj.getString("bsalamt"), obj.getString("tsalamt"), obj.getString("tsalamtsum"), obj.getString("salper"), obj.getString("colamt"), obj.getString("colamtsum"), obj.getString("colper")));                                                   String str = obj.getString("salamt");                        str = str.replaceAll(",", "");                                                 int sal = Integer.parseInt(str);                        tsal = tsal + sal;                                     }                                     }                catch (JSONException e)                {                    e.printStackTrace();                }                                       gv.setAdapter(adapter);            }            total1.setText(tsal);            pb.cancel();        }

소스에서 리스트의 추가될때마다 sal 이 스트링형이라 인트형으로 교환후 tsal 에 계속 넣고 있습니다.

합이 구해지는거 까지 확인을 하였습니다. 

하지만  텍스트뷰에 합을 넣으려고 하는데 오류가 나서 질문을 드리게 되었습니다.

Answer 1

TextView의 setText(int resid) 함수는 리소스 아이디를 파라미터로 받는 메소드에요

R.string.xxx 이런 스트링 리소스를 셋할때 쓰는 메소드란 뜻이구요,

int값을 TextView에 스트링으로 출력하고 싶으면 String.valueOf()함수를 이용해서

total1.setText(String.valueOf(tsal)); 이런식으로 써주셔야 해요

감사합니다 텍스트뷰 자체에는 인트형이 못들어가는 것은 몰랐었네요 감사합니다.
