java - Json 解析作为逻辑练习

Question

以前，我应该说，我的英语很糟糕。我对此感到抱歉。我在我的 android 项目中解析想要 Json 输出。我的 json 文件带有 url。就像那里一样

{
  "urun": [
    {
      "ID": "1011245",
      "name": "Jeanne Darc-Elbise-jdje57942xl",
      "name_eng": "Jeanne Darc-Dress-jdje57942xl",
      "catID": "142",
      "tedarikciCode": "jdje57942xl",
      "markaID": "30",
      "data1": "4",
      "resim": "var/30/jdje57942xl/siyah_1_jdje57942xl.jpg",
      "resim2": "var/30/jdje57942xl/siyah_2_jdje57942xl.jpg",
      "resim3": "var/30/jdje57942xl/siyah_3_jdje57942xl.jpg",
      "fiyat": "28",
      "ozellik1detay": "44-50"
    }
] 
}

我的解析器类是

    public class JsonParsers
{
final String TAG = "JsonParsers.java";
static InputStream is  =null;
    static JSONObject jObj=null;
static String ParserJson=null;

    public JsonParsers(String yourJsonStringUrl) {
    }

    public JsonParsers() {
        super();
    }

    public String getJsonUrl(String url) throws IOException {
        try{
            DefaultHttpClient httpClient=new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity=httpResponse.getEntity();
            is=httpEntity.getContent();
        }
        catch (UnsupportedEncodingException e)
        {
            e.printStackTrace();
        }
        catch (ClientProtocolException e)
        {
            e.printStackTrace();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
        try
        {
            BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
            StringBuilder sb= new StringBuilder();
            String line = "";
            while ((line=reader.readLine())!=null)
            {

                sb.append(line+"\n");
                //Log.e("çıktı:",line);
            }
            is.close();
            ParserJson = sb.toString();


        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        try {
            jObj=new JSONObject(ParserJson);

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

        return ParserJson;


    }


}

我的 asyncTask 类是

 private class AsyncTaskParseJSonIncludes extends AsyncTask<String, String, String> {
    final String TAG = "MainActivity.java";

    JSONArray dataJsonArr = null;
    String ObjectStr;






    protected String doInBackground(String... path)  {
       try{

        try{

            JsonParsers parser = new JsonParsers();

            //Json = parser.getJsonUrl(JsonPath);
            ObjectStr=parser.getJsonUrl(JsonPath);
            JSONObject Json= new JSONObject(ObjectStr);
            dataJsonArr=Json.getJSONArray("urun");

            for(int i=0;i<dataJsonArr.length();i++)
            {
                 JSONObject c = dataJsonArr.getJSONObject(i);
                // Log.e("Deneme", c.getString("name"));
                ID.add(Integer.valueOf(c.getString("ID")));
                name.add(c.getString("name"));
                name_eng.add(c.getString("name_eng"));
                //name_py.add(c.getString("name_py"));
                CatID.add(Integer.valueOf(c.getString("CatID")));
                tedarikciCode.add(c.getString("tedarikciCode"));
                 markaID.add(Integer.valueOf(c.getString("markaID")));
                data1.add(Integer.valueOf(c.getString("data1")));
                resimmmm.add(c.getString("resim"));
                resim2.add(c.getString("resim2"));
                resim3.add(c.getString("resim3"));
                fiyat.add(Integer.valueOf(c.getString("fiyat")));
                ozellik1detay.add(c.getString("ozellik1detay"));
              //  ozellik2detay.add(c.getString("ozellik2detay"));




            }
          for(int i=0;i<name.size();i++) {
                Log.e("Deneme", name.get(i));
            }


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

        return null;
    }
    protected void onPreExecute() {}

工作正常，但没有返回json值。我检查数据流的解析器类，它是固定的。但只返回第一个值，其他数据不返回。我不明白这是逻辑问题。当有人帮助我修复我的代码时，我很有趣。谢谢。

Answer 1

name_eng.add().

name_eng 是在哪里定义的？

CatID 到 catID。

右:

Try{A}catch{}
Try{B}catch{}
Try{C}catch{}

错误:

Try{A;B;C}catch{}
