未调用自定义Adapter getView()方法

Question

未调用自定义Adapter getView()方法下面是我正在为列表设置自定义适配器的片段的代码。除了ListView是空的。我已经实施了getCount()它返回我的ArrayList中正确的项目数。我看不出来("Inside", "GetView")在夜猫子里碎片public class ServiceCarListFragment extends Fragment {     private String url;     private ArrayList<CarDetail> carDetailList = new ArrayList<CarDetail>();     private CarListAdapter adapter;     private ListView mList;     @Override     public void onCreate(Bundle savedInstanceState) {         // TODO Auto-generated method stub         super.onCreate(savedInstanceState);         url = getActivity().getIntent().getStringExtra("url");         new DownloadCarDetail().execute(url);     }     @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container,                              Bundle savedInstanceState) {         // TODO Auto-generated method stub         View v = inflater.inflate(R.layout.fragment_service_car_list, container, false);         mList = (ListView) v.findViewById(R.id.list);         mList.setAdapter(adapter);         for (CarDetail car : carDetailList) {             // START LOADING IMAGES FOR EACH STUDENT             car.loadImage(adapter);         }         return v;     }     class DownloadCarDetail extends AsyncTask<String, String, ArrayList<CarDetail>> {         @Override         protected ArrayList<CarDetail> doInBackground(String... params) {             // TODO Auto-generated method stub             ArrayList<CarDetail> carDetailList = JsonParser.parseJson(params[0]);             return carDetailList;         }         @Override         protected void onPostExecute(ArrayList<CarDetail> carDetailList) {             // TODO Auto-generated method stub             ServiceCarListFragment.this.carDetailList = carDetailList;             Log.d("dccs", String.valueOf(ServiceCarListFragment.this.carDetailList.size()));             adapter = new CarListAdapter(getActivity(), ServiceCarListFragment.this.carDetailList);             Log.d("dccs", String.valueOf((adapter.getCount())));         }     }

在向列表中添加项时，必须验证列表中的元素可能存在错误。若要验证，请使用以下方法：

adapter.getCount();
