如何使用json webservice在android中填充spinner

我用了这个密码

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.wisknowtech.com/hotel_jobs/country_list.php");         
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpclient.execute(httppost,responseHandler);                     
JSONObject json = new JSONObject(responseBody);

JSONArray jArray = json.getJSONArray("data");
//JSONArray  jsonArray = new JSONArray(responseBody);

final String[] array_spinner = new String[jArray.length()];                         

final Spinner countryspiner = (Spinner) findViewById(R.id.rescountry);                             
ArrayAdapter<String> classNameAdapter = new ArrayAdapter<String>(this,                            android.R.layout.simple_spinner_item,array_spinner);
                 classNameAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
for (int i=0; i<jArray.length(); i++)
{
     String styleValue = jArray.getJSONArray(i).getString(0); 
     array_spinner[i] = styleValue;
}
countryspinner.setAdapter(classNameAdapter);
}
catch (JSONException e) {
    e.printStackTrace();
} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}  

HttpClient-HttpClient=newdefaulthttpclient（）；
HttpPost HttpPost=新的HttpPost（“http://www.wisknowtech.com/hotel_jobs/country_list.php");         
ResponseHandler ResponseHandler=新BasicResponseHandler（）；
字符串responseBody=httpclient.execute（httppost，responseHandler）；
JSONObject json=新的JSONObject（ResponseBy）；
JSONArray jArray=json.getJSONArray（“数据”）；
//JSONArray JSONArray=新的JSONArray（响应库）；
最终字符串[]数组_微调器=新字符串[jArray.length（）]；
最终微调器countryspiner=（微调器）findViewById（R.id.rescountry）；
ArrayAdapter classNameAdapter=新的ArrayAdapter（这是android.R.layout.simple\u微调器\u项，数组微调器）；
classNameAdapter.setDropDownViewResource（android.R.layout.simple\u微调器\u下拉菜单\u项）；
对于（int i=0；i
