圖像在滾動的自定義列表視圖中重複

每當我試圖從JsonArray中移除一個對象時，它就會顯示沒有這樣的方法存在。我的目標API版本是8.我查找有關此問題的其他問題，但無法找到合適的解決方案。請幫我解決一下這個。圖像在滾動的自定義列表視圖中重複

class JSONAsync extends AsyncTask<String, Void, JSONArray> 
{ 


    @Override 
    protected void onPreExecute() 
    { 
     super.onPreExecute(); 
     progressDialog = Util.setProgressDialog(Activity.this, "Please Wait", 
       "loading....", false); 
     progressDialog.show(); 
    } 

    @Override 
    protected JSONArray doInBackground(String... urls) 
    { 

     try 
     {  
      HttpGet httppost = new HttpGet(url); 
      HttpClient httpclient = new DefaultHttpClient(); 
      HttpResponse response = httpclient.execute(httppost); 

      // StatusLine stat = response.getStatusLine(); 
      int status = response.getStatusLine().getStatusCode(); 

      if (status == 200) 
      { 
       HttpEntity entity = response.getEntity(); 
       String resString = EntityUtils.toString(entity); 

       JSONObject jso= new JSONObject(resString); 

       JSONArray jsono= jso.getJSONArray("jobmasterto"); 
       Log.e("jason array is this", ""+jsono); 
       for (int i = 0; i < jsono.length(); i++) { 
        if (jsono.getJSONObject(i).getString("jobName").equals(null) || jsono.getJSONObject(i).getString("jobName").equals("null") || jsono.getJSONObject(i).getString("jobName").equals("")) { 
         Log.e("Output : : ", jsono.getJSONObject(i).getString("jobName")); 
         jsono.remove(i);

發表您的自定義適配器類的'getView（）'方法 –

你真的想頭疼支持這麼老設備的比特數量？

然而，使用此：

JSONObject jso= new JSONObject(resString); 

JSONArray jsonArray = jso.getJSONArray("jobmasterto"); 

Log.e("jason array is this", ""+jsonArray); 
ArrayList<Integer> i_ar = new ArrayList<Integer>(); 
       for (int i = 0; i < jsonArray.length(); i++) { 
        if (jsonArray.getJSONObject(i).getString("jobName").equals(null) || jsonArray.getJSONObject(i).getString("jobName").equals("null") || jsonArray.getJSONObject(i).getString("jobName").equals("")) { 
         Log.e("Output : : ", jsonArray.getJSONObject(i).getString("jobName")); 
         i_ar.add(i); 
        } 



       }    

JSONArray jsono = new JSONArray(); 

int len = jsonArray.length(); 
if (jsonArray != null) { 
    for (int i=0;i<len;i++) 
    { 
     //Excluding the item at position 
     if (i_ar.indexOf(i) == -1) 
     { 
      list.put(jsonArray.get(i)); 
     } 
    } 
} 



       if(jsono.length()>=0) 
       { 
//.... continue...
