jsonarray无法转换为jsonobject logcat错误

oke我得到了几个JSONArrays，我已经添加为一个JSONArray JSONArray并存储在一个文件中。jsonarray无法转换为jsonobject logcat错误

这是我的JSON声明：

这是我加入阵列创建文件的代码：

public void createJSONExampleDataFile(JSONArray jArray) { 


     File f = new File(fileJSON); 
     f.delete(); 
     if (!f.exists()) { 
      try { 
       FileWriter fos = new FileWriter(f); 
       fos.write(jArray.toString()); 
       fos.close(); 

      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } else { 
      try { 
       f.delete(); 
       FileWriter fos = new FileWriter(f); 
       fos.write(jArray.toString()); 
       fos.close(); 

      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 
    } 
public JSONArray createJSONExampleData() { 
     JSONArray ar = new JSONArray(); 

     ar.put(createJSONWineExampleData()); 
     ar.put(createJSONReviewExampleData()); 
     return ar; 
    } 

    public JSONObject createJSONWineExampleData() { 
     winesJSONArray = new JSONArray(); 
     JSONObject o= new JSONObject(); 

     for (int i = 0; i < 10; i++) { 
      jObj = new JSONObject(); 
      try { 
       jObj.put(JSON_WINE_BARCODE, Long.valueOf((1234567890123L + (i * 129347)))); 
       jObj.put(JSON_WINE_BARCODETYPE, "EAN13"); 
       jObj.put(JSON_WINE_NAME, "Wine number: " + i); 
       jObj.put(JSON_WINE_YEAR, (1982 + i)); 
       jObj.put(JSON_WINE_COUNTRY, "Netherlands"); 
       jObj.put(JSON_WINE_TASTE, "Sweet"); 
       jObj.put(JSON_WINE_COLOR, "Red"); 
       jObj.put(JSON_WINE_DESCRIPTION, "This wine number " + i + " is a very sweet red wine."); 
       jObj.put(JSON_WINE_SPARKLING, 1); 
       jObj.put(JSON_WINE_BIOLOGIC, 0); 

       System.out.println(jObj.toString()); 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 
      winesJSONArray.put(jObj); 
     } 
     try { 
      o.put(JSON_ARRAY_WINE, winesJSONArray); 
     } catch (JSONException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     return o; 
    } 

    public JSONObject createJSONReviewExampleData() { 
     reviewWineJSONArray = new JSONArray(); 
     JSONObject o= new JSONObject(); 

     for (int i = 0; i < 5; i++) { 
      jObj = new JSONObject(); 
      try { 
       jObj.put(JSON_REVIEWWINE_REVIEWID, 1+i); 
       jObj.put(JSON_REVIEWWINE_WINEID, Long.valueOf((1234567890123L + (i * 129347)))); 
       jObj.put(JSON_REVIEWWINE_REVIEW, i); 
       jObj.put(JSON_REVIEWWINE_DATE, 1340826068189L-(i*12999823)); 
       jObj.put(JSON_REVIEWWINE_TITLE, "SWeet red: "+i); 

       System.out.println(jObj.toString()); 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 
      reviewWineJSONArray.put(jObj); 
     } 
     try { 
      o.put(JSON_ARRAY_REVIEWWINE, reviewWineJSONArray); 
     } catch (JSONException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     return o; 
    }

这是我试图与它的代码，以获得阵列1出来的：

public JSONObject getJSONObjectWineFromJSONObjectArray(JSONObject jsonOb, String barcode) { 
     JSONArray jsonAr = new JSONArray(); 

     try { 
      jsonAr = jsonOb.getJSONArray(JSON_ARRAY_WINE); 
     } catch (JSONException e1) { 
      // TODO Auto-generated catch block 
      e1.printStackTrace(); 
     } 

     for (int i = 0; i < jsonAr.length(); i++) { 
      try { 
       jsonAr.getJSONObject(i); 
       if (jsonAr.getJSONObject(i).getString(JSON_WINE_BARCODE).equals(barcode)) { 
        return jsonAr.getJSONObject(i); 
       } 

      } catch (JSONException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
     } 
     return null; 
    } 

public JSONArray getJSONArrayWinesFromFile() { 

     try { 
      is = new FileInputStream(new File(fileJSON)); 
      BufferedReader reader = new BufferedReader(
        new InputStreamReader(is)); 
      StringBuilder sb = new StringBuilder(); 
      String line = null; 
      while ((line = reader.readLine()) != null) { 
       sb.append(line + "\n"); 
      } 
      is.close(); 
      json = sb.toString(); 
      System.out.println("Dit is de string: "+json.toString()); 

     } catch (FileNotFoundException e) { 
      Log.e("File Error", "Error getting file result " + e.toString()); 
     } catch (Exception e) { 
      Log.e("Buffer Error", "Error converting result " + e.toString()); 
     } 
     try { 
      JSONObject jOb = new JSONObject(json); 

      winesJSONArray = jOb.getJSONArray(JSON_ARRAY_WINE); 

      System.out.println("Lets see: "+winesJSONArray.toString(1)); 


     } catch (JSONException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     return winesJSONArray; 
    }

这是logcat的是我从中得到了：

这是我从文件中得到的字符串，所以我必须把它作为一个onject而不是数组呢？

所以你需要有

JSONArray JR =新JSONArray（ “jsonstring”）;因此，替换

JSONObject jOb = new JSONObject（json）;通过

JSONArray jr = new JSONArray（json）;

我想这：

try { 
      winesJSONArray = new JSONArray(json); 

      System.out.println(winesJSONArray.toString()); 


      System.out.println("Lets see: "+winesJSONArray.toString(1));

，并得到这个的logcat：

'[{“wines”：[{'是你在logcat中所拥有的，而你说你的json是这样的''wine'：['。所以我很困惑 – Raghunandan

在logcat中添加了json字符串 – cc2k

立即检查我的帖子 – Raghunandan

我想第一个问题是，你有什么“思考”你作为示例数据VS你“真的”与示例数据。

您显示了一个JSONObject数据示例，其中的字段包含数组数据，但在您的createJSONExampleDataFile(JSONArray jArray)中，您正在编写JSONArray作为顶级项目，而不是JSONObject。稍后，当您读回时，您正在尝试读取JSONObject，但您之前写入的内容为JSONArray，因此您将收到关于无法将JSONArray转换为JSONObject的错误。

所以修复将修改createJSONExampleDataFile接受JSONObject，并重构代码，这样你所保存的最顶部的对象类型是JSONObject（包含几个JSONArray字段成员）

所以，对于初学者来说，

public JSONArray createJSONExampleData() { 
    JSONArray ar = new JSONArray(); 

    ar.put(createJSONWineExampleData()); 
    ar.put(createJSONReviewExampleData()); 
    return ar; 
}

应该是这样的......

public JSONObject createJSONExampleData() { 
    JSONObject ar = new JSONObject(); 

    ar.put("wines",createJSONWineExampleData()); 
    ar.put("reviewWine",createJSONReviewExampleData()); 
    return ar; 
}

即JSONArray被存储在JSONObject中，根据您的原始数据绑定到字段名称，这使得稍后可以使用那些相同的命名字段检索它们。

我试过了，并且列表正在再次查看，但是我在logcat中得到了这个错误，警告.. http://pastebin.com/gEdKxif7 – cc2k

从不记住我明白了，我忘了把字符串放在jsonobject中，然后从它得到酒数组，ty，这就解决了我的问题，据我所见：D。 – cc2k

[表示JSON数组节点

{代表JSON对象节点

所以你需要有

JSONArray jr = new JSONArray("jsonstring");

因此，请替换

JSONObject jOb = new JSONObject(json);

通过

JSONArray jr = new JSONArray(json);
