有谁能告诉我如何获取这个彻底的Json数组或Json对象的数据？ 在这里我也把网址，我已经把我尝试过的一些 所有数据都变成一个变量.... 这里是src名称对象我想要搜索的内容如下：http://i.ytimg.com/vi/cpqLJrFNBSY/0.jpg

4 个答案:

答案 0 :(得分：1)

首先，您的JSON响应无效，第二个

您的代码行

 jArray=jObject.getJSONArray("Guru");

您的回复中没有名为“Guru”的元素。

理想的方式应该是，

String jsonItem = JSONObject.getJSONArray("Array Name").getString("string name");

您可以使用此link来验证json的有效性并查看树结构。

答案 1 :(得分：0)

以下是您的解决方案，

String href = JSONResponse.getJSONObject("feed").getJSONArray("entry").getJSONObject("0").getJSONArray("link").getJSONObject("0").getString("href");

您可以通过树以相同的方式解析其他值。 希望这会有所帮助。

答案 2 :(得分：0)

这是你的j-son链接获得标题的解决方案。就像这样，你可以得到href和你想要的一切。

  StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);

ArrayList<String> title_list = new ArrayList<String>();

        HttpClient httpclient = new DefaultHttpClient();
        httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
        HttpGet request = new HttpGet("http://gdata.youtube.com/feeds/base/videos?max-results=10&start-index=1&alt=json&orderby=published&author=astrobixweb");

        try
        {
        HttpResponse response = httpclient.execute(request);
        HttpEntity resEntity = response.getEntity();
        String _response=EntityUtils.toString(resEntity); // content will be consume only once

        //Log.v("Test", ""+_response);

        jsonarray = new JSONArray("["+_response+"]");
        json = jsonarray.getJSONObject(0);
        String feed = (json.getString("feed"));

        Log.v("feed", ""+feed);

        try{


            jsonarray = new JSONArray("["+feed+"]");

            json = jsonarray.getJSONObject(0);

            String entry  = json.getString("entry");

            jsonarray = new JSONArray(entry);

            for (int i = 0; i < jsonarray.length(); i++) {

                json = jsonarray.getJSONObject(i);

                 String title_array  = json.getString("title");

                 jsonArray1 = new JSONArray("["+title_array+"]");

                 String title = jsonArray1.getJSONObject(0).getString("$t");

                 title_list.add(title);

        }
            Log.v("title", ""+title_list);

        }catch (Exception e){
            e.printStackTrace();
        }
        }catch (Exception e){
            e.printStackTrace();
        }
}

检查出来：

String str = "<assign your json string>"
        try {
            JSONObject jObject=new JSONObject(str);
            jObject = jObject.getJSONObject("feed");
            JSONObject jObject1 = jObject.getJSONObject("title");
            Log.d("$t==", jObject1.getString("$t"));
            Log.d("type==", jObject1.getString("type"));
            JSONArray jArrayObject = new JSONArray(jObject.getString("link"));
            for (int i = 0; i<jArrayObject.length(); i++) {
                Log.d("href==", jArrayObject.getJSONObject(i).getString("href").toString());
            }
            JSONArray jArrayObject5 = new JSONArray(jObject.getString("entry"));
            for (int i = 0; i<jArrayObject5.length(); i++) {
                JSONObject jObject3 = jArrayObject5.getJSONObject(i).getJSONObject("title");
                Log.d("$t==", jObject3.getString("$t"));
                Log.d("type==", jObject3.getString("type"));
                JSONArray jArrayObject6 =  new JSONArray(jArrayObject5.getJSONObject(i).getString("link").toString());
                for (int j = 0; j<jArrayObject6.length(); j++) {
                    Log.d("href==", jArrayObject6.getJSONObject(j).getString("href").toString());
                }

            }
        } catch (Exception e) {
        }
