JSONARRAY Data에서 테이블 레이아웃에 동적으로 행을 추가하는 방법은 무엇입니까?

Question

나는 두 개의 TextViews와 하나의 EditText로 iphone과 같은 내 tableview에 동적으로 행을 추가하고 싶습니다. 또한 webservices에 대한 데이터 편집을 위해 Scrolling tableview를 원합니다. ineed som 샘플 코드 그래서 내가 진행할 수 또는 어떤 alternet 솔루션 plz 날 제안하는 경우.

나는이 JSON을 가지고 내가 어떤 친구는 이것에 대한 해결책을 가지고 있습니다 도움이 필요 그래서 안드로이드 새로운이 메신저를 실현하려있는 tableview의 각 행에

try { 
     json = new JSONObject(status); 
     getArray_Meter_Reading = new JSONArray(); 
     getArray_Meter_Reading = json.getJSONArray("meterReadings"); 
     if (getArray_Meter_Reading.length() == 0) { 
      AlertDialog.Builder builder = new AlertDialog.Builder(
        NewTransaction.this); 
      builder.setTitle("WARNING"); 
      builder.setIcon(android.R.drawable.ic_dialog_alert); 
      builder.setMessage("No Meters Found"); 
      builder.setPositiveButton("ok", 
        new DialogInterface.OnClickListener() { 

         public void onClick(DialogInterface dialog, 
           int which) { 


         } 
        }); 

      AlertDialog diag = builder.create(); 
      diag.show(); 
     } 

    } catch (JSONException e) { 


     e.printStackTrace(); 
    } 

Plz은 도움말을 JSON 데이터를 바인딩 할. 사전에 덕분에

public View getView(final int position, View convertView, ViewGroup parent) { 
    View view = super.getView(position, convertView, parent); 
    EditText ed_Current = (EditText) view.findViewById(R.id.ed_Current); 
    ed_Current.setTag(position); 






    ed_Current.setOnFocusChangeListener(new View.OnFocusChangeListener() { 

     public void onFocusChange(View arg0, boolean arg1) { 

      if (v == null) { 
       v = arg0; 

       int tag = (Integer) arg0.getTag(); 
       Caption = (EditText) arg0; 

       previous_Meter_Reading = new HashMap<String, String>(); 
       previous_Meter_Reading = c.get(tag); 
       String getPreviousReading = previous_Meter_Reading 
         .get("previousMeterReading"); 
       String CumulativeIndex = previous_Meter_Reading 
         .get("Cumulative"); 
       previousMeterReading = Integer.parseInt(getPreviousReading); 
       Cumulative = Integer.parseInt(CumulativeIndex); 
      }

        int tag = ((Integer) arg0.getTag()); 
        CurrentMeterReading = Integer.valueOf(Caption.getText() 
          .toString()); 

        CurrentReading =new HashMap<String, Integer>(); 
        CurrentReading.put("Tag"+tag,CurrentMeterReading); 
        getReading.add(CurrentReading); 

        Log.i("Curr", "Current" + CurrentMeterReading);

              int which) { 

             // Caption.requestFocus(); 

            } 
           }); 

         AlertDialog diag = builder.create(); 
         diag.show(); 

         // Caption.requestFocus(); 
         // v = null; 
         // Caption = null; 
        }else if(Cumulative==0 && !Caption.getText().toString().equals("")){ 

         //int tag1 = ((Integer) arg0.getTag()); 
         CurrentMeterReading = Integer.valueOf(Caption.getText() 
           .toString()); 

         CurrentReading =new HashMap<String, Integer>(); 
         CurrentReading.put("Tag"+tag,CurrentMeterReading); 
         getReading.add(CurrentReading); 
        } 

       } 

       v = null; 
       Caption = null; 
      }

Layout:- 

레이아웃을 생성 한 후

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"

</RelativeLayout> 

은 먼저 당신은 테이블에 값을 할당 한 다음 JSON 데이터 를 검색 문자열 []에 저장합니다 귀하의 요구 사항에 에 따라. 예를 들어 다음을 통해 이동하십시오.

활동 : -

public class ProvisionActivity extends Activity { 

    private TableLayout mTable; 
    private static int sCount = 0; 
    Button btnAdd; 
    String[] pnames = { "provision1", "provision2", "provision3", "provision4",
