之前,我应该说,我的英语非常糟糕。对不起。 我解析想要Json输出,在我的android项目中。我的json文件是url。 就像那里
{
"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() {}

它正常工作,但它没有返回json值。 我检查解析器类的数据流,它是固定的。 但它只返回第一个值,其他数据不返回。 我不明白它的逻辑问题。有人帮我修理我的代码我非常好笑。谢谢。

name_eng.add().
name_eng定义在哪里?
CatID to catID。
右:
Try{A}catch{}
Try{B}catch{}
Try{C}catch{}
错误:
Try{A;B;C}catch{}

尝试GsonRequest,解析JSON非常简单,使用它的好例子:USE GsonRequest
