I have a ProgressDialog that retrieves in background data from database by executing php script.
I'm using gson Google library. php script is working well when executed from browser:
{"surveys":[{"id_survey":"1","question_survey":"Are you happy with the actual government?","answer_yes":"50","answer_no":"20"}],"success":1}
However, ProgressDialog background treatment is not working well:
@Override
protected Void doInBackground(Void... params) {
String url = "http://192.168.1.4/tn_surveys/get_all_surveys.php";
HttpGet getRequest = new HttpGet(url);
Log.d("GETREQUEST",getRequest.toString());
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
Log.d("URL1",url);
HttpResponse getResponse = httpClient.execute(getRequest);
Log.d("GETRESPONSE",getResponse.toString());
final int statusCode = getResponse.getStatusLine().getStatusCode();
Log.d("STATUSCODE",Integer.toString(statusCode));
Log.d("HTTPSTATUSOK",Integer.toString(HttpStatus.SC_OK));
if (statusCode != HttpStatus.SC_OK) {
Log.w(getClass().getSimpleName(), "Error " + statusCode + " for URL " + url);
return null;
}
HttpEntity getResponseEntity = getResponse.getEntity();
Log.d("RESPONSEENTITY",getResponseEntity.toString());
InputStream httpResponseStream = getResponseEntity.getContent();
Log.d("HTTPRESPONSESTREAM",httpResponseStream.toString());
Reader inputStreamReader = new InputStreamReader(httpResponseStream);
Gson gson = new Gson();
this.response = gson.fromJson(inputStreamReader, Response.class);
}
catch (IOException e) {
getRequest.abort();
Log.w(getClass().getSimpleName(), "Error for URL " + url, e);
}
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
Log.d("HELLO","HELLO");
StringBuilder builder = new StringBuilder();
Log.d("STRINGBUILDER","STRINGBUILDER");
for (Survey survey : this.response.data) {
String x= survey.getQuestion_survey();
Log.d("QUESTION",x);
builder.append(String.format("<br>ID Survey: <b>%s</b><br> <br>Question: <b>%s</b><br> <br>Answer YES: <b>%s</b><br> <br>Answer NO: <b>%s</b><br><br><br>", survey.getId_survey(), survey.getQuestion_survey(),survey.getAnswer_yes(),survey.getAnswer_no()));
}
Log.d("OUT FOR","OUT");
capitalTextView.setText(Html.fromHtml(builder.toString()));
progressDialog.cancel();
}
HELLO Log is displayed.
STRINGBUILDER Log is displayed.
QUESTION Log is NOT displayed.
OUT FOR Log is displayed.
Survey Class:
public class Survey {
int id_survey;
String question_survey;
int answer_yes;
int answer_no;
public Survey() {
this.id_survey = 0;
this.question_survey = "";
this.answer_yes=0;
this.answer_no=0;
}
public int getId_survey() {
return id_survey;
}
public String getQuestion_survey() {
return question_survey;
}
public int getAnswer_yes() {
return answer_yes;
}
public int getAnswer_no() {
return answer_no;
}
}
Response Class:
public class Response {
ArrayList<Survey> data;
public Response() {
data = new ArrayList<Survey>();
}
}
Any help please concerning WHY the FOR loop is not executed.
Thank you for helping.
