解析JsonObject时出错

Question

我想从DownloadTask获取JsonObject。但是我得到的数组值存储在downloadData中以及存储在jsonObjectText中的JsonObjects中。在日志中查看下面。 为什么我的代码返回数组与JsonObject，但我只记录jsonObject变量的内容。日志的

这里图片：

这里是我的代码：

package com.example.smarpitsingh.webview; 

public class MainActivity extends AppCompatActivity { 

    String name = "Result"; 
    String result = "",downloadedData,jsonObjectText; 
    URL url; 
    HttpURLConnection httpURLConnection; 
    InputStream inputStream; 
    InputStreamReader streamReader; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     DownloadTask downloadTask = new DownloadTask(); 
     try { 
      downloadedData = downloadTask.execute("https://hacker-news.firebaseio.com/v0/topstories.json?print=pretty").get(); 

      JSONArray jsonArray = new JSONArray(downloadedData); 

      for (int i=1; i<20; i++){ 

       DownloadTask jasonTask = new DownloadTask(); 
       jsonObjectText = jasonTask.execute("https://hacker-news.firebaseio.com/v0/item/"+jsonArray.getString(i)+".json?print=pretty").get(); 

       Log.i(name,jsonObjectText); 
      } 


     } catch (InterruptedException e) { 
      e.printStackTrace(); 
     } catch (ExecutionException e) { 
      e.printStackTrace(); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
    } 

    public class DownloadTask extends AsyncTask<String,Void,String>{ 

     @Override 
     protected String doInBackground(String... urls) { 
      try { 
       url = new URL(urls[0]); 
       httpURLConnection = (HttpURLConnection)url.openConnection(); 
       inputStream = httpURLConnection.getInputStream(); 
       streamReader = new InputStreamReader(inputStream); 

       int data = streamReader.read(); 
       while (data != -1){ 
        char count = (char)data; 
        result += count; 
        data = streamReader.read(); 
       } 

      } catch (MalformedURLException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 


      return result; 
     } 
    } 
`}`

因为你有你的JSON数组：
