Android的问题解析JSON(Android problems with parsing jso

你好，我想从我的网站解析JSON。特jsonString我从TE的HttpResponse获取工作正常，但是当我试图解析它在的JSONObject它提供了NPE。这与现在的JSON IM测试：

{ "galgjejson" :
        { "Nederlands" :  
                            { "length7" : [ 
                                                { "word" : "android" }, 
                                                { "word" : "camping" },
                                                { "word" : "koekjes" }
                                            ]
                            },

                                                { "word" : "somewordddd" },
                                                { "word" : "somewordddd" },
                                                { "word" : "somewordddd" }
                                            ]
                            },
                            { "length12" : [
                                                { "word" : "someworddddd" },
                                                { "word" : "someworddddd" },
                                                { "word" : "someworddddd" }
                                            ]
                            }

        }

}

我做的方法：

    public MikeyJSON(String jsonString) {
    Log.i("JSON", "jsonString: " + jsonString);
    try {
        JSONObject myObject = new JSONObject(jsonString);
        Log.i("JSON", "myObject_Object: " + myObject.toString());
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

public String getResult(String lang, String length, int wordPos) {
    String word = "0";  

    try {
        langObject = myObject.getJSONObject(lang);
        Log.i("JSON", "Language_Object " + langObject.toString());
        lengthObject = langObject.getJSONObject(length);
        Log.i("JSON", "wordlength_Object " + lengthObject.toString());
        wordArray = lengthObject.getJSONArray(length);
        Log.i("JSON", "wordlength_Object " + wordArray.toString());
        if(wordPos>wordArray.length()) {
            wordPos = 0;
        }
        for(i=0;i<wordArray.length();i++){
            word = wordArray.getJSONObject(wordPos).toString();
        }
        Log.i("JSON", "word_Object " + word);

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

    return word;        
}
}

我试图找回仅仅是一个给定的语言和长度的字。这是我的很多研究后提出，但我只是不明白为什么它不会工作。如果我的JSON是无效的请求告诉我，我做错了什么，我监守得到了NPE在此之前的错误：

Answer 1:

您的JSON是无效的 - 这是正确的格式：

{ "Nederlands" :  [
                        { "length7" : [ 
                                            { "word" : "android" }, 
                                            { "word" : "camping" },
                                            { "word" : "koekjes" }
                                        ]
                        }, 
                        { "length8" : [
                                            { "word" : "androids" },    
                                            { "word" : "campings" },
                                            { "word" : "campings" },
                                            { "word" : "campings" },
                                            { "word" : "campings" },
                                            { "word" : "campings" },
                                            { "word" : "scheppen" }
                                        ]
                        }]
}

目前，“荷兰”是一个JSONArray格式（它所持有多一个JSONObjects），但你的反应缺少方括号。如果您解析“荷兰”作为JSONArray和一个删除“长度”一个JSONObjects之一，那么你应该能够使它工作

Answer 2:

尝试实体转换为字符串如下然后用杰森对象

  response = httpclient.execute(httpget);

HttpEntity entity = response.getEntity();

String responseBody = EntityUtils.toString(entity);

  JSONObject obj = new JSONObject(responseBody);
