android - Can someone help me with this JSON Parsing? -
there problem when retrieve individual elements the json. : "t":"sbin"
the json-url follows : http://finance.google.com/finance/info?q=bse:sbin
and other resources follows :
public class refreshstock extends asynctask<string, string, list<stockmodel>> { @override protected list<stockmodel> doinbackground(string... params) { try { url = new url(params[0]); connection = (httpurlconnection) url.openconnection(); connection.connect(); inputstream = connection.getinputstream(); bufferedreader = new bufferedreader(new inputstreamreader(inputstream)); stringbuffer = new stringbuffer(); string line = ""; while ((line = bufferedreader.readline()) != null) stringbuffer.append(line + "\n"); string data = stringbuffer.tostring(); return parsejson(data); } catch (malformedurlexception e) { e.printstacktrace(); } catch (ioexception e) { e.printstacktrace(); } { if (connection != null) connection.disconnect(); try { if (bufferedreader != null) bufferedreader.close(); } catch (ioexception e) { e.printstacktrace(); } } return null; } private list<stockmodel> parsejson(string json) { list<stockmodel> stockmodellist = new arraylist<>(); json = json.substring(3); //textview.settext(""+json); try { stockmodel stockmodel = new stockmodel(); jsonobject parentobject = new jsonobject(); jsonarray jsonarray = parentobject.getjsonarray(json); jsonobject childobject = jsonarray.getjsonobject(0); string stockid = childobject.getstring("id"); string stockname = childobject.getstring("t"); string stockrate = childobject.getstring("l"); string stockchange = childobject.getstring("c"); string stockchangepercent = childobject.getstring("cp"); toast.maketext( getapplicationcontext(),""+stockrate, toast.length_long).show(); stockmodel.setid(stockid); stockmodel.sett(stockname); stockmodel.setl(stockrate); stockmodel.setc(stockchange); stockmodel.setcp(stockchangepercent); stockmodellist.add(stockmodel); return stockmodellist; } catch (jsonexception e) { e.printstacktrace(); } return stockmodellist; } protected void onpostexecute(list<stockmodel> result) { super.onpostexecute(result); stockadapter adapter = new stockadapter(getapplicationcontext(), r.layout.listrow, result); lvstock.setadapter(adapter); } } the logcat message follows:
