如何僅從JSON服務器響應中獲取「文本」？

Question

我收到服務器的響應爲JSON格式，並需要獲得單場「文本」並將其存儲在數組列表。我試過，但只獲得第一個文本字段，如下面顯示的輸出，但我需要證據列表中的所有文本字段json object.Can任何人都可以幫助我在這裏獲得所有文本字段？

的Android代碼：從服務器

HttpEntity entity = response.getEntity(); // wait for response 
      // convert response to a string and log it 
      if (entity != null) { 

            //Toast.makeText(RegistartionPage.this, 
         // "Inside If", Toast.LENGTH_LONG) 
         //.show(); 
      InputStream inputstream = entity.getContent(); 
      BufferedReader bufferedreader = 
      new BufferedReader(new InputStreamReader(inputstream)); 
      StringBuilder stringbuilder = new StringBuilder(); 
      String currentline = null; 
      while ((currentline = bufferedreader.readLine()) != null) { 
       //Toast.makeText(RegistartionPage.this, 
         // "Inside while", Toast.LENGTH_LONG) 
         // .show(); 
      stringbuilder.append(currentline + "\n"); 
      } 
      String result = stringbuilder.toString(); 
      Log.v("HTTP REQUEST",result); 
      inputstream.close(); 

      ids=result; 

      } 
      JSONArray jsonArray = new JSONArray(ids); 
      for (int i = 0; i < jsonArray.length(); i++) { 
       JSONObject c = jsonArray.getJSONObject(i); 
       String question1 = c.getString("question"); 
       JSONObject object2 = new JSONObject(question1); 
       JSONArray jArray1 = object2.getJSONArray("evidencelist"); 
       //String comp_id = jArray1.optString(); 
       for(int j = 0; j < jArray1 .length(); j++) 
       { 
        JSONObject object3 = jArray1.getJSONObject(j); 
        text = object3.getString("text"); 
        /*num = object3.getInt("value");*/ 

       } 
      }

試試這個..

JSONArray jsonArray = new JSONArray(ids); 
for (int i = 0; i < jsonArray.length(); i++) { 
    JSONObject ques_obj = jsonArray.getJSONObject(i); 

    JSONObject question = ques_obj.getJSONObject("question"); 

    JSONArray q = question.getJSONArray("qclasslist"); 
    JSONArray f = question.getJSONArray("focuslist"); 
    JSONArray l = question.getJSONArray("latlist"); 

    for (int a = 0; a < q.length(); a++) { 
     JSONObject q_obj = q.getJSONObject(a); 
     text = q_obj .getString("value"); 
    } 
    for (int b = 0; b < f.length(); b++) { 
     JSONObject f_obj = f.getJSONObject(b); 
     text = f_obj.getString("value"); 

    } 

    for (int c = 0; c < l.length(); c++) { 
     JSONObject l_obj = l.getJSONObject(c); 

     text = l_obj.getString("value"); 
    } 

    JSONArray jArray1 = question.getJSONArray("evidencelist"); 

    for(int d = 0; d < jArray1 .length(); d++) 
    { 
     JSONObject object3 = jArray1.getJSONObject(d); 
     text = object3.getString("text"); 
    } 
}
