내 목록 조각이 표시되지 않습니다

Question

actionBarSherlock을 SherlockListFragment과 함께 사용하고 있으며 사용자 지정 BaseAdpater을 설정하고 싶습니다. JSON을 구문 분석하고 어댑터를 채우려면 AsyncTask을 사용하고 있습니다. 그러나 listview은 보이지 않습니다. 조각이 비어 있습니다. 이것은 내가 노력하고 코드입니다 :

public class LatestSubmissions extends SherlockListFragment { 

    LatestSubmissionsAdapter adapter = null; 

    ArrayList<HashMap<String, String>> submissions = new ArrayList<HashMap<String, String>>(); 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     new GetSubmissionsListTask().execute(CommonUtils.USER_SUBMISSION_URL); 
     return super.onCreateView(inflater, container, savedInstanceState); 
    } 

    protected class GetSubmissionsListTask extends 
      AsyncTask<String, Void, String> { 

     @Override 
     protected String doInBackground(String... params) { 
      return new JSONFetcher().getJSONStringFromUrl(params[0]); 
     } 

     @Override 
     protected void onPostExecute(String result) { 
      try { 
       JSONObject jObject = new JSONObject(result); 
       //related code 
       submissions.add(map); 
       } 
      } catch (JSONException e) { 

      } 
      adapter = new LatestSubmissionsAdapter(getSherlockActivity(), submissions); 
      setListAdapter(adapter); 
     } 
    } 
} 

그리고 이것은 LatestSubmissionsAdapter입니다 :

public class LatestSubmissionsAdapter extends BaseAdapter { 
    private Context mContex; 
    private ArrayList<HashMap<String, String>> data; 
    private static LayoutInflater inflater = null; 

    public LatestSubmissionsAdapter(Context context, 
      ArrayList<HashMap<String, String>> data) { 
     this.mContex = context; 
     this.data = data; 
     inflater = (LayoutInflater) mContex 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return 0; 
    } 

    @Override 
    public Object getItem(int arg0) { 
     // TODO Auto-generated method stub 
     return null; 
    } 

    @Override 
    public long getItemId(int position) { 
     // TODO Auto-generated method stub 
     return 0; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View vi = convertView; 
     if (convertView == null) 
      vi = inflater.inflate(R.layout.latest_submissions, null); 
     RelativeLayout firstRow = (RelativeLayout) vi 
       .findViewById(R.id.first_row); 
     TextView language = (TextView) firstRow.findViewById(R.id.lang); 
     TextView verdict = (TextView) firstRow.findViewById(R.id.verdict); 
     RelativeLayout secondRow = (RelativeLayout) vi 
       .findViewById(R.id.second_row); 
     TextView problem = (TextView) secondRow 
       .findViewById(R.id.problem_name_id); 
     TextView rank = (TextView) secondRow.findViewById(R.id.rank); 
     RelativeLayout thirdRow = (RelativeLayout) vi 
       .findViewById(R.id.third_row); 
     TextView submissionTime = (TextView) thirdRow 
       .findViewById(R.id.submit_time); 
     TextView executionTime = (TextView) thirdRow 
       .findViewById(R.id.exec_time); 

     HashMap<String, String> submissionInfo = new HashMap<String, String>(); 
     submissionInfo = data.get(position); 

     language.setText(submissionInfo.get(CommonUtils.KEY_LANGUAGE_ID)); 
     verdict.setText(submissionInfo.get(CommonUtils.KEY_VERDICT_ID)); 

     problem.setText(submissionInfo.get(CommonUtils.KEY_PROBLEM_ID)); 
     rank.setText(submissionInfo.get(CommonUtils.KEY_SUBMISSION_RANK)); 

     submissionTime.setText(submissionInfo 
       .get(CommonUtils.KEY_SUBMISSION_TIME)); 
     executionTime.setText(submissionInfo.get(CommonUtils.KEY_RUNTIME)); 

     return vi; 
    } 

} 

json으로 제대로 ownloaded 및 구문 분석됩니다. 그러나 문제는 listview입니다. ListView에 당신이 0 항목이 생각하기 때문에

Answer 1

당신은 그게 아무것도 표시되지 않는 이유, 제대로

@Override 
public int getCount() { 
    // TODO Auto-generated method stub 
    return 0; 
} 

@Override 
public Object getItem(int arg0) { 
    // TODO Auto-generated method stub 
    return null; 
} 

@Override 
public long getItemId(int position) { 
    // TODO Auto-generated method stub 
    return 0; 
} 

을 overrid해야합니다.
