數據加載到列表視圖

Question

我有一個應用程序到Android，如下

public class MainActivity extends Activity { 
    private final String URL_SERVICE = "http://92.253.101.239:81/sudandoctors/api.aspx?op=5&GovernorateId=&SpecializationId=&DoctorName=&LastDoctorId=0"; 
    private final String URL_IMAGE_BASE = "http://92.253.101.239:81/sudandoctors/UploadedFiles/"; 
    TextView tv; 
    DoctorInfo doctorObj = new DoctorInfo(); 
    ArrayList<DoctorInfo> doctorsInfoList = new ArrayList<DoctorInfo>(); 

    ListView lv = (ListView)findViewById(R.id.mylist); 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


     AsyncHttpClient client = new AsyncHttpClient(); 

     client.get(URL_SERVICE, new AsyncHttpResponseHandler() { 
      @Override 
      public void onStart() { 
       super.onStart(); 
       // show loading bar 
       Log.d("onStart", "onStart"); 
      } 

      @Override 
      public void onSuccess(String response) { 
       super.onSuccess(response); 
       Log.d("onSuccess", "onSuccess"); 
       DoctorsModel doctorModel = new DoctorsModel(); 
       ArrayList<DoctorInfo> doctorsInfoList = new ArrayList<DoctorInfo>(); 

       try { 
        // convert response to JSON 
        JSONObject json = new JSONObject(response); 

        // get JSON Items 
        doctorModel.setDoctorCnt(json.getInt("DoctorsCount")); 
        doctorModel.setOp(json.getString("op")); 

        JSONArray doctorsArray = json.getJSONArray("Doctors"); 
        Log.d("dr arrat", doctorsArray.toString()); 
        for (int i = 0; i < doctorsArray.length(); i++) { 
         JSONObject doctorJSON = doctorsArray.getJSONObject(i); 


         doctorObj .setId(doctorJSON.getString("Id")); 
         Log.d("id", doctorJSON.getString("Id")); 
         doctorObj.setName(doctorJSON.getString("DoctorName")); 
         doctorObj.setGovernorateId(doctorJSON.getString("GovernorateId")); 
         doctorObj.setGovernorateName(doctorJSON.getString("GovernorateName")); 
         doctorObj.setSpecializationName(doctorJSON.getString("SpecializationName")); 
         doctorObj.setHospitalId(doctorJSON.getString("HospitalId")); 
         doctorObj.setHospitalName(doctorJSON.getString("HospitalName")); 
         doctorObj.setImageName(URL_IMAGE_BASE + doctorJSON.getString("ImageName")); 
         doctorObj.setMobile(doctorJSON.getString("Mobile")); 
         doctorObj.setSpecializationId(doctorJSON.getString("SpecializationId")); 
         doctorObj.setWeekendDays(doctorJSON.getString("WeekendDays")); 
         doctorObj.setWorkingDays(doctorJSON.getString("WorkingDays")); 
         doctorObj.setWorkingTime(doctorJSON.getString("WorkingTime")); 

         doctorsInfoList.add(doctorObj); 
        } 
       } catch (JSONException e) { 
        e.printStackTrace(); 
       } 
      } 

      @Override 
      public void onFailure(Throwable e, String message) { 
       super.onFailure(e, message); 
       // show error message 
      } 

      @Override 
      public void onFinish() { 
       super.onFinish(); 
       // remove loading bar 
      } 
     }); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
        android.R.layout.activity_list_item); 

       // Assign adapter to ListView 
       lv.setAdapter(adapter); 
     getMenuInflater().inflate(R.menu.activity_main, menu); 
     return true; 
    } 

} 

其負載數據從JSON和我要在列表中顯示的數據來看，我該怎麼辦呢？

使用適配器 - http://developer.android.com/reference/android/widget/Adapter.html

創建數據適配器，然後設置適配器作爲ListView的適配器。
