public class standingslist extends fragment implements view.onclicklistener { //make member variable views button mbutton; button mbutton1; textview mresult; string json_response; string json_string; progressdialog mprogressdialog; @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { // inflate layout fragment view view = inflater.inflate( r.layout.fragment_standings, container, false ); //get reference of views mbutton = (button) view.findviewbyid( r.id.button ); mbutton1 = (button) view.findviewbyid( r.id.buttontwo ); mresult = (textview) view.findviewbyid( r.id.result ); mbutton1.setonclicklistener(this); //when button clicked mbutton.setonclicklistener( new view.onclicklistener() { @override public void onclick(view view) { //call getjsonresponse method , fetch response server new getjsonresponse().execute(); } } ); return view; } public class getjsonresponse extends asynctask<void, void, string> { string serverurl; public getjsonresponse() { mprogressdialog = new progressdialog( getactivity() ); mprogressdialog.setmessage( "please wait" ); mprogressdialog.settitle( "processing" ); mprogressdialog.setcancelable( false ); } @override protected void onpreexecute() { //set url have fetch json response serverurl = "http://163.172.142.145/get_info.php"; mprogressdialog.show(); } @override protected string doinbackground(void... params) { try { url url = new url( serverurl ); httpurlconnection httpurlconnection = (httpurlconnection) url.openconnection(); inputstream inputstream = httpurlconnection.getinputstream(); bufferedreader bufferedreader = new bufferedreader( new inputstreamreader( inputstream ) ); stringbuilder stringbuilder = new stringbuilder(); while ((json_response = bufferedreader.readline()) != null) { stringbuilder.append( json_response + "\n" ); } inputstream.close(); bufferedreader.close(); httpurlconnection.disconnect(); return stringbuilder.tostring().trim(); } catch (malformedurlexception e) { log.e( tag, "malformedurlexception: " + e ); //print exception message log } catch (ioexception e) { log.e( tag, "ioexception: " + e ); //print exception message log } return null; } @override protected void onprogressupdate(void... values) { super.onprogressupdate( values ); } @override protected void onpostexecute(string result) { //set result returned doinbackground() method result textview mresult.settext( result ); mprogressdialog.dismiss(); json_string = result; } } public void onclick(view view){ switch (view.getid()) { case r.id.buttontwo: intent intent = new intent(getactivity(), displaylistview.class); intent.putextra( "json_data",json_string ); startactivity( intent ); break; } } } the last class have works alongside json parse display in list view class, meant named. here below:
public class displaylistview extends appcompatactivity { string json_string; jsonobject jsonobject; jsonarray jsonarray; standingsadapter standingsadapter; listview listview; @override protected void oncreate(bundle savedinstancestate) { super.oncreate( savedinstancestate ); setcontentview( r.layout.display_list_view_layout ); listview= (listview) findviewbyid( r.id.listviewparse ); standingsadapter = new standingsadapter(this,r.layout.row_layout); listview.setadapter( standingsadapter ); json_string = getintent().getextras().getstring( "json_data" ); try { jsonarray = new jsonobject(json_string).getjsonarray("server_response"); int count = 0; int driver_id, team_id, position, points; string firstname, lastname; while(count<jsonarray.length()) { jsonobject jo = jsonarray.getjsonobject(count); driver_id = jo.getint( "driver_id" ); team_id =jo.getint( "team_id" ); firstname = jo.getstring( "first_name" ); lastname= jo.getstring( "last_name" ); position= jo.getint( "position" ); points = jo.getint( "points" ); standings standings = new standings(driver_id, team_id, firstname, lastname, position, points ); standingsadapter.add( standings ); count++; } } catch (jsonexception e) { e.printstacktrace(); } } }
you need convert int values string using integer.tostring(intargument);
standings standings = (standings)this.getitem( position ); standingsholder.tx_id.settext( integer.tostring(standings.getdriver_id()) ); standingsholder.txt_id.settext(integer.tostring(standings.getteam_id())); standingsholder.tx_fn.settext( standings.getfirstname() ); standingsholder.tx_ln.settext( standings.getlastname() ); standingsholder.tx_pos.settext(integer.tostring(standings.getposition())); standingsholder.tx_po.settext(integer.tostring(standings.getpoints()));
