Android 如何使用自定义arrayAdapter在onPostExecute中列出mssql记录。我写了以下代码，但当我执行时，应用程序停止了

我想在android listview中列出我的mssql记录。这是我的密码

活动

public class YoneticiMenuActivity extends Activity {

JSONObject jsonObject = null;
//JSONArray jsonArray = null;
//public Is isler = new Is();
//public ArrayList<Is> arrayIsler = new ArrayList<Is>();

    int mode = Activity.MODE_PRIVATE;
    SharedPreferences mSP;
    mSP = getSharedPreferences(mesaj, mode);

    String baslik = mSP.getString("name", "") + " " + mSP.getString("surname", "") + ", Hoşgeldiniz";
    setTitle(baslik);

    lvTumIsler = (ListView)findViewById(R.id.lvTumIsler);
    new AsyncTaskYonetici("Veriler yükleniyor...").execute();

        }

        IsAdapter adapter = new IsAdapter(YoneticiMenuActivity.this, R.layout.layouttumisler, arrayIsler);
        lvTumIsler.setAdapter(adapter);

        if (dialog.isShowing())
            dialog.dismiss();
    }
}

private void Mesaj(String s) {

    Toast.makeText(this, s, Toast.LENGTH_LONG).show();
}

}

我在主布局中使用listview，在Layoutumısler中有6个textview。我在myAsyncTask的onPostExecute中使用IsAdapter，但当我执行应用程序时，它会停止。 mssql记录确实来自web服务，但我无法列出。我在IsAdapter getView中出错，在

tvUrunId.setText(is.getId());

---

请帮帮我…

我换衣服时犯了个大错

public int getId() {return urunId;}

作为

代码是有效的

tvUrunId.setText(is.getId());

public int getId() {return urunId;}

public String getId() 
{
    String s = Integer.toString(urunId);
    return s;
}
