我在这里遇到问题。我试图检索一个配置文件，以便我可以查看它，然后根据需要进行更新。但是，它一直在返回，得到配置文件时出错。但是，没有堆栈跟踪，只有我的标签进行调试。谁能帮我？异步任务获取错误
这里的片段：
public static class ProfileSectionFragment extends Fragment {
public ProfileSectionFragment() {
}
public static final String ARG_SECTION_NUMBER = "section_number";
TextView nameDesc, name, contactTV, emailTV, addressTV, postalTV;
EditText contactET, emailET, addressET1, addressET2, addressET3,
postalET;
Button update;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
recLifeCycle_with_savedInstanceState(savedInstanceState);
View rootView = inflater.inflate(R.layout.fragment_profile,
container, false);
nameDesc = (TextView) rootView.findViewById(R.id.nameDescTV);
name = (TextView) rootView.findViewById(R.id.nameTV);
contactTV = (TextView) rootView.findViewById(R.id.contactTV);
emailTV = (TextView) rootView.findViewById(R.id.emailTV);
addressTV = (TextView) rootView.findViewById(R.id.addressTV);
postalTV = (TextView) rootView.findViewById(R.id.postalTV);
contactET = (EditText) rootView.findViewById(R.id.contactET);
emailET = (EditText) rootView.findViewById(R.id.emailET);
addressET1 = (EditText) rootView.findViewById(R.id.addressET1);
addressET2 = (EditText) rootView.findViewById(R.id.addressET2);
addressET3 = (EditText) rootView.findViewById(R.id.addressET3);
postalET = (EditText) rootView.findViewById(R.id.postalET);
update = (Button) rootView.findViewById(R.id.updateButton);
Button unlink = (Button) rootView.findViewById(R.id.unlinkButton);
Log.i("User_id profile", user_id);
new GetProfileAsyncTask((MainActivity) getActivity()).execute(user_id);
update.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if (update.getText().equals("Update My Particulars")) {
update.setText("Done");
contactET.setClickable(true);
contactET.setCursorVisible(true);
emailET.setClickable(true);
emailET.setCursorVisible(true);
addressET1.setClickable(true);
addressET1.setCursorVisible(true);
addressET2.setClickable(true);
addressET2.setCursorVisible(true);
addressET3.setClickable(true);
addressET3.setCursorVisible(true);
postalET.setClickable(true);
postalET.setCursorVisible(true);
}
if (update.getText().equals("Done")) {
// make async task to update particulars
update.setText("Update My Particulars");
contactET.setClickable(false);
contactET.setCursorVisible(false);
emailET.setClickable(false);
emailET.setCursorVisible(false);
addressET1.setClickable(false);
addressET1.setCursorVisible(false);
addressET2.setClickable(false);
addressET2.setCursorVisible(false);
addressET3.setClickable(false);
addressET3.setCursorVisible(false);
postalET.setClickable(false);
postalET.setCursorVisible(false);
}
}
});
unlink.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
nyp.edu.sg.alumnigo.SharedPreferences.clearUserName(getActivity());
Intent intent = new Intent(getActivity(), LoginActivity.class);
startActivity(intent);
}
});
return rootView;
}
public void addDetails(final Profile profile){
Log.i("Profile/Profile", profile.toString());
name.setText(profile.getName());
contactET.setText(profile.getContact());
emailET.setText(profile.getEmail());
addressET1.setText(profile.getAddLine1());
addressET2.setText(profile.getAddLine2());
addressET3.setText(profile.getAddLine3());
postalET.setText(profile.getPostal());
}
然后，这里的异步任务：
public class GetProfileAsyncTask extends AsyncTask<String, Integer, Boolean>{
ProgressDialog progressDialog;
MainActivity activityMain;
Profile profile;
public GetProfileAsyncTask(MainActivity parent)
{
activityMain = parent;
}
@Override
protected void onPreExecute() {
}
@Override
protected Boolean doInBackground(String... params) {
// TODO Auto-generated method stub
Boolean error = false;
try {
error = getData(params[0]);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return error;
}
protected void onPostExecute(Boolean error){
if(error == true)
{
Log.i("GetProfile", "Error at get profile");
activityMain.errorOccured();
}
else
{
activityMain.getProfileSuccess(profile);
}
}
protected void onProgressUpdate(Integer... progress){
}
public Boolean getData(String userId) throws JSONException {
Boolean error = false;
HttpClient httpclient = new DefaultHttpClient();
// specify the URL you want to post to
try {
HttpGet httpget = new HttpGet(Constants.HOST_NAME+"/"+Constants.SERVICE_NAME+"/api/Account/"+userId);
BufferedReader reader;
StringBuffer sb;
String line = "";
String NL="";
String json;
HttpResponse response = httpclient.execute(httpget);
if(response.getStatusLine().getStatusCode()==200)
{
reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
sb = new StringBuffer("");
line = "";
NL = System.getProperty("line.separator");
while ((line = reader.readLine()) != null)
{
sb.append(line + NL);
}
reader.close();
json = sb.toString();
Log.i("profile json",json);
try
{
JSONObject jsonObj = new JSONObject(json);
JSONObject attr = jsonObj.getJSONObject(json);
profile = new Profile();
if(attr.has("Name"))
{
profile.setName(attr.getString("Name"));
profile.setAddLine1(attr.getString("AddressLineOne"));
profile.setAddLine2(attr.getString("AddressLineTwo"));
profile.setAddLine3(attr.getString("AddressLineThree"));
profile.setPostal(attr.getString("PostalCode"));
profile.setContact(attr.getString("HomeTel"));
profile.setEmail(attr.getString("Email"));
Log.i("Async/Profile", profile.toString());
}
}
catch (JSONException e)
{
e.printStackTrace();
error = true;
}
}
else
{
error = true;
}
}
catch (ClientProtocolException e)
{
// process execption
e.printStackTrace();
error = true;
}
catch (IOException e)
{
// process execption
e.printStackTrace();
error = true;
}
return error;
}
}
这是一个异步任务的调用（这是主要的活动范围内）的方法：
public void getProfileSuccess(Profile profile) {
final ProfileSectionFragment fragment = (ProfileSectionFragment) getSupportFragmentManager().findFragmentByTag(getProfileFragmentTag());
Log.i("Main/Profile", profile.toString());
fragment.addDetails(profile);
}
然后，如果需要，这里是xml：

貌似还有就是当你打电话的getData一些错误。当你在getDate方法中捕获异常时，可能会添加更多的日志标记？ – alpinescrambler 2014-10-16 16:54:51
看起来我有更多的日志需要显示。我会添加它。 – 2014-10-16 17:04:26
你期望什么'JSONObject jsonObj = new JSONObject（json）; JSONObject attr = jsonObj.getJSONObject（json）;'做什么？ – njzk2 2014-10-16 17:08:59
