內BaseAdapter類的getView（）沒有得到

Question

我的代碼，具體如下：問題是，getView()方法不會被調用一次我檢查了我的日誌本

我的片段類是

public class AlertListFragment extends Fragment { 
    // TODO: Rename parameter arguments, choose names that match 
    // the fragment initialization parameters, e.g. ARG_ITEM_NUMBER 
    private static final String ARG_PARAM1 = "param1"; 
    private static final String ARG_PARAM2 = "param2"; 

    // TODO: Rename and change types of parameters 
    private String mParam1; 
    private String mParam2; 

    private OnFragmentInteractionListener mListener; 
    public ArrayList<AlertModel> mModelLIst=new ArrayList<AlertModel>(); 
    public AlertAdapter adapter; 
    ListView mAlertList; 
    CommentsDataSource datasource; 



    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     if (getArguments() != null) { 
      mParam1 = getArguments().getString(ARG_PARAM1); 
      mParam2 = getArguments().getString(ARG_PARAM2); 
     } 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     View view=inflater.inflate(R.layout.fragment_alert_list, container, false); 
     mAlertList=(ListView)view.findViewById(R.id.alertlist); 

     System.out.println("details in fragment"); 
     datasource = new CommentsDataSource(getActivity()); 
     datasource.open(); 
     ArrayList<AlertModel> source = datasource 
       .getAllContacts(); 

     if (source.size() > 0) { 
      System.out.println("response number of items" 
        + source.size()); 

      adapter = new AlertAdapter(getActivity(), source,getActivity().getResources()); 
      mAlertList.setAdapter(adapter); 


      } 

     return inflater.inflate(R.layout.fragment_alert_list, container, false); 
    } 

    // TODO: Rename method, update argument and hook method into UI event 
    public void onButtonPressed(Uri uri) { 

    } 

    @Override 
    public void onAttach(Activity activity) { 
     super.onAttach(activity); 

    } 

    @Override 
    public void onDetach() { 
     super.onDetach(); 

    } 
} 

我的適配器類是

public class AlertAdapter extends BaseAdapter implements View.OnClickListener { 

    private Activity activity; 
    private ArrayList data; 
    ArrayList<String> btnpositions = new ArrayList<String>(); 
    public Resources res; 

    private static LayoutInflater inflater = null; 
    ViewHolder holder; 
    AlertModel tempValue = null; 

    public AlertAdapter(Activity activity, ArrayList data, Resources res) { 

     System.out.println("response number of items inside adapter view: "); 
     this.activity = activity; 
     this.data = data; 
     this.res = res; 

    } 




    public static class ViewHolder { 

     public TextView msubject, mbody; 
     public ImageView mTYpe; 

     public LinearLayout mTYpeLay; 

    } 


    @Override 
    public int getCount() { 


    System.out.println("response number of items inside adapter count: "+data.size()); 
     if (data.size() <= 0) 
      return 1; 

     System.out.println("response number of items inside adapter count: "+data.size()); 
     return data.size(); 

    } 

    @Override 
    public Object getItem(int position) { 
     return null; 
    } 

    @Override 
    public long getItemId(int position) { 
     return 0; 
    } 

    @Override 
    public View getView(int arg0, View vis, ViewGroup arg2) { 


     System.out.println("response number of items inside adapter view: "+arg0); 
     View vi = vis; 

     int crntposition = arg0; 
     Context context; 

     if (vis == null) { 


      inflater = (LayoutInflater) activity. 
        getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

      vi = inflater.inflate(R.layout.alert_list_item, null); 
     } else 
      holder = (ViewHolder) vi.getTag(); 

     holder = new ViewHolder(); 

     holder.msubject = (TextView) vi.findViewById(R.id.txtsubject); 
     holder.mbody = (TextView) vi.findViewById(R.id.txtbody); 
     holder.mTYpe = (ImageView) vi.findViewById(R.id.imgtype); 
     holder.mTYpeLay=(LinearLayout)vi.findViewById(R.id.typelay); 

     if (data.size() <= 0) { 
      holder.msubject.setText("No Data"); 

     } else { 
      vi.setTag(holder); 
      vi.setTag(R.id.txtsubject, holder.msubject); 
      vi.setTag(R.id.txtbody, holder.mbody); 
      vi.setTag(R.id.imgtype, holder.mTYpe); 

      holder.msubject.setTag(crntposition); 
      holder.mbody.setTag(crntposition); 
      holder.mTYpe.setTag(crntposition); 


      tempValue = null; 
      tempValue = (AlertModel) data.get(crntposition); 


      /************ Set Model values in Holder elements ***********/ 

      context = arg2.getContext(); 

      holder.msubject.setText(tempValue.getmMessage()); 
      if(tempValue.getmMessage().equalsIgnoreCase("1")) 
      { 
       holder.mTYpeLay.setBackgroundResource(R.color.quote_blue); 
       holder.mTYpe.setBackgroundResource(R.drawable.q); 
      } 
      else if(tempValue.getmMessage().equalsIgnoreCase("2")) 
      { 
       holder.mTYpeLay.setBackgroundResource(R.color.event_yellow); 
       holder.mTYpe.setBackgroundResource(R.drawable.e); 
      } 
      else 
      { 
       holder.mTYpeLay.setBackgroundResource(R.color.wishes_red); 
       holder.mTYpe.setBackgroundResource(R.drawable.bday); 
      } 




     } 

     vi.setOnClickListener(new OnItemClickListener(crntposition)); 

     return vi; 

    } 
    @Override 
    public void onClick(View v) { 

     Log.e("click","yess"); 

    } 
    private class OnItemClickListener implements View.OnClickListener { 
     private int mPosition; 

     OnItemClickListener(int position) { 

      mPosition = position; 



      System.out.println("pos"+mPosition); 
     } 

     @Override 
     public void onClick(View arg0) { 



     } 

    } 

}

和我的輸出是

Answer 1

，你必須在你onCreateView錯誤的返回，與

return inflater.inflate(R.layout.fragment_alert_list, container, false); 

你完全返回新的充氣視圖，ListView，完全沒有你的適配器知識。將其更改爲

return view;
