still not working?
i made project myself, , if work. :)
the r.id , drawables not same, need change make work
textview weather; imageview forecast; private static handler mhandler = new handler(); class myweather{ string conditiontext; string conditiondate; string numberofforecast; string forecast; public string forecasttostring(){ return "\n- " + "weather: " +"you wanted have here, dont understand what. " + "\n" + "condition: " + conditiontext + "\n" + conditiondate +"\n" + "\n" + "number of forecast: " + numberofforecast + "\n" + forecast; } } @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); weather = (textview)findviewbyid(r.id.textview1); forecast = (imageview)findviewbyid(r.id.imageview1); thread mythread = new thread(new runnable(){ @override public void run() { string weatherstring = queryyahooweather(); document weatherdoc = convertstringtodocument(weatherstring); final myweather weatherresult = parseweather(weatherdoc); runonuithread(new runnable(){ @override public void run() { weather.settext(weatherresult.forecasttostring()); }}); }}); mythread.start(); } private myweather parseweather(document srcdoc){ myweather myweather = new myweather(); //<yweather:condition.../> node conditionnode = srcdoc.getelementsbytagname("yweather:condition").item(0); string weathercode = conditionnode.getattributes() .getnameditem("code") .getnodevalue() .tostring(); if(weathercode.equals("28")){ mhandler.post(new runnable() { @override public void run() { // gets executed on ui thread can safely modify // views forecast.setimageresource(r.drawable.ic_launcher); } }); } ...
