转换字符串到json数组出错

在Android 日志:

代码:

//Download text -------------------------------------------------------------
private String DownloadText(String urlString){
    InputStream in = null;
    StringBuilder sb = new StringBuilder();
    try{
        in = OpenHttpConnection(urlString);
        BufferedReader br = new BufferedReader(new InputStreamReader(in));
        String line="";
        while((line = br.readLine())!= null){
            sb.append(line);
        }
    }catch(IOException ex){

    }
    return sb.toString();
}

//Parse JSON text -----------------------------------------------------------
private FBUser pasreJSON(String url){
    FBUser user = null;
    JSONArray json;
    Log.d("JSON----------------",DownloadText(url));
    try {
        user = new FBUser();
        json = new JSONArray(DownloadText(url));
        for(int i=0;i<json.length();i++){
            JSONObject object = json.getJSONObject(i);
            user.id = object.getString("id");
            user.name = object.getString("name");
            user.first_name = object.getString("first_name");
            user.last_name = object.getString("last_name");
            user.link = object.getString("link");
            user.username = object.getString("username");
            user.gender = object.getString("gender");
            user.locale = object.getString("locale");
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }

    return user;
}

哪出错了呢?

    错了,应该是

    JSONObject json = new JSONObject(DownloadText(url));
    JsonArray jsonArray  = json.getJsonArray("yourArrayKey");
    
    for() {
    
    }

    JSONObject object = new JSONObject (DownloadText(url));
                         user.id = object.getString("id");   
                   user.name = object.getString("name");  
                    user.first_name = object.getString("first_name"); 
                     user.last_name = object.getString("last_name"); 
                     user.link = object.getString("link");         
             user.username = object.getString("username");        
              user.gender = object.getString("gender");            
          user.locale = object.getString("locale");
