我正在审查，显然问题出在转换 q json 但正如我所说我是 java 新手，android 不明白如何修复它，我留下我的 Java 代码，顺便说一下我使用 AsyncTask 会提到.. .
try {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("cedula", cedula));
Log.i("1","busca empleado para cargar detalles");
// getting Empleado details by making HTTP request
// Note that Empleado details url will use GET request
**JSONObject json = jsonParser.makeHttpRequest(
url_detalles_empleado, "GET", params);**
Log.i("1","llama a php busqueda");
// check your log for json response
Log.d("Single Empleado Details", json.toString());
// json success tag
success = json.getInt(TAG_SUCCESS);
在此先感谢，希望您的帮助谢谢..
