java - Onpostexecute method is never used -
i'm getting "onpostexecute method never used" error , hence dialog box never closes, not sure mistake is. i'm sure mistake brackets somewhere i've been trying figure out while , can't, perhaps fresh pair of eyes can in case.
public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_display_all_bets); name = (getintent().getextras().getstring("user")).tolowercase(); log.d("name", name); // hashmap listview bet = new arraylist<hashmap<string, string>>(); // loading products in background thread new loadallgames().execute(); } /** * background async task load product making http request */ class loadallgames extends asynctask<string, string, string> { private string id; private string stake; private string user; private string returns; private string teams; private string status; // *//** // * before starting background thread show progress dialog // *//* @override protected void onpreexecute() { super.onpreexecute(); pdialog = new progressdialog(displayallbets.this); pdialog.setmessage("loading games. please wait..."); pdialog.setindeterminate(false); pdialog.setcancelable(false); pdialog.show(); } // *//** // * getting products url // *//* protected string doinbackground(string... args) { // building parameters httpclient client = new defaulthttpclient(); httppost post = new httppost(url_all_games); list<namevaluepair> params = new arraylist<namevaluepair>(); params.add(new basicnamevaluepair("email", name)); try { post.setentity(new urlencodedformentity(params)); } catch (ioexception ioe) { ioe.printstacktrace(); } try { httpresponse response = client.execute(post); log.d("http post response:", response.tostring()); httpentity httpentity = response.getentity(); inputstream = httpentity.getcontent(); jsonobject jobj = null; string json = ""; try { bufferedreader reader = new bufferedreader(new inputstreamreader( is, "iso-8859-1"), 8); stringbuilder sb = new stringbuilder(); string line = null; while ((line = reader.readline()) != null) { if (!line.startswith("<", 0)) { if (!line.startswith("(", 0)) { sb.append(line + "\n"); } } } is.close(); json = sb.tostring(); json = json.substring(json.indexof('{')); log.d("sb", json); } catch (exception e) { log.e("buffer error", "error converting result " + e.tostring()); } // try parse string json object try { jobj = new jsonobject(json); } catch (jsonexception e) { log.e("json parser", "error parsing data " + e.tostring()); } // return json string log.d("json", jobj.tostring()); try { allgames = jobj.getjsonarray(tag_bet); log.d("allgames", allgames.tostring()); // looping through products (int = 0; < allgames.length(); i++) { jsonobject c = allgames.getjsonobject(i); // storing each json item in variable string id = c.getstring(tag_id); string user = c.getstring(tag_user); string returns = c.getstring(tag_returns); string stake = c.getstring(tag_stake); string status = c.getstring(tag_status); string teams = c.getstring(tag_teams); log.d("id", id); log.d("user", user); log.d("returns", returns); log.d("stake", stake); log.d("status", status); log.d("teams", teams); // creating new hashmap hashmap<string, string> map = new hashmap<string, string>(); // adding each child node hashmap key => value map.put(tag_id, id); map.put(tag_teams, teams); map.put(tag_user, user); map.put(tag_returns, returns); map.put(tag_stake, stake); map.put(tag_status, status); // adding hashlist arraylist bet.add(map); } } catch (jsonexception e) { e.printstacktrace(); } } catch (ioexception ioe) { ioe.printstacktrace(); } return ""; } @override protected void onpostexecute() { // dismiss dialog after getting products // updating ui background thread pdialog.dismiss(); } } @override public boolean oncreateoptionsmenu(menu menu) { // inflate menu; adds items action bar if present. getmenuinflater().inflate(r.menu.menu_display_all_bets, menu); return true; } @override public boolean onoptionsitemselected(menuitem item) { // handle action bar item clicks here. action bar // automatically handle clicks on home/up button, long // specify parent activity in androidmanifest.xml. int id = item.getitemid(); //noinspection simplifiableifstatement if (id == r.id.action_settings) { return true; } return super.onoptionsitemselected(item); } }
you defined asynctask as,
class loadallgames extends asynctask<string, string, string> for which, should have onpostexecute(string) type
@override protected void onpostexecute(string param) { // dismiss dialog after getting products // updating ui background thread pdialog.dismiss(); } should work.
