you need 2 classes 1. activity 2. json parser
here sample code 2 of them, can modify per own needs
public class jsonparser { static inputstream = null; static jsonobject jobj = null; static string json = ""; static jsonarray jarr = null; // constructor public jsonparser() { } // function json url // making http post or method public jsonobject makehttprequest(string url, string method, list<namevaluepair> params) { // making http request try { // check request method if(method == "post"){ // request method post // defaulthttpclient defaulthttpclient httpclient = new defaulthttpclient(); httppost httppost = new httppost(url); httppost.setentity(new urlencodedformentity(params)); httpresponse httpresponse = httpclient.execute(httppost); httpentity httpentity = httpresponse.getentity(); = httpentity.getcontent(); }else if(method == "get"){ // request method defaulthttpclient httpclient = new defaulthttpclient(); string paramstring = urlencodedutils.format(params, "utf-8"); url += "?" + paramstring; httpget httpget = new httpget(url); httpresponse httpresponse = httpclient.execute(httpget); httpentity httpentity = httpresponse.getentity(); = httpentity.getcontent(); } } catch (unsupportedencodingexception e) { e.printstacktrace(); } catch (clientprotocolexception e) { e.printstacktrace(); } catch (ioexception e) { e.printstacktrace(); } try { bufferedreader reader = new bufferedreader(new inputstreamreader( is, "utf-8"), 8); stringbuilder sb = new stringbuilder(); string line = null; while ((line = reader.readline()) != null) { sb.append(line + "\n"); } is.close(); json = sb.tostring(); } catch (exception e) { log.e("buffer error", "error converting result " + e.tostring()); } log.i("php error", "["+json+"]"); // try parse string json object try { jobj = new jsonobject(json); } catch (jsonexception e) { log.e("json parser", "error parsing data " + e.getmessage() + json); } // return json string return jobj; } public jsonarray getallmessages(string url, string method, list<namevaluepair> params) { // making http request try { // check request method if(method == "post"){ // request method post // defaulthttpclient defaulthttpclient httpclient = new defaulthttpclient(); httppost httppost = new httppost(url); httppost.setentity(new urlencodedformentity(params)); httpresponse httpresponse = httpclient.execute(httppost); httpentity httpentity = httpresponse.getentity(); = httpentity.getcontent(); }else if(method == "get"){ // request method defaulthttpclient httpclient = new defaulthttpclient(); string paramstring = urlencodedutils.format(params, "utf-8"); url += "?" + paramstring; httpget httpget = new httpget(url); httpresponse httpresponse = httpclient.execute(httpget); httpentity httpentity = httpresponse.getentity(); = httpentity.getcontent(); } } catch (unsupportedencodingexception e) { e.printstacktrace(); } catch (clientprotocolexception e) { e.printstacktrace(); } catch (ioexception e) { e.printstacktrace(); } try { bufferedreader reader = new bufferedreader(new inputstreamreader( is, "utf-8"), 8); stringbuilder sb = new stringbuilder(); string line = null; while ((line = reader.readline()) != null) { sb.append(line + "\n"); } is.close(); json = sb.tostring(); } catch (exception e) { log.e("buffer error", "error converting result " + e.tostring()); } log.i("php error", "["+json+"]"); // try parse string json object try { jarr = new jsonarray(json); } catch (jsonexception e) { log.e("json parser", "error parsing data " + e.getmessage() + json); } // return json string return jarr; } } activity
public class home extends activity { private progressdialog pdialog; jsonparser jsonparser = new jsonparser(); string message; private static string url_addmessage = "http://www.yourdomain.com/addmessage.php"; private static final string tag_success = "success"; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_home); final edittext et = (edittext)findviewbyid(r.id.edittext1); button b1 = (button)findviewbyid(r.id.button1); button b2 = (button)findviewbyid(r.id.button2); b1.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { // todo auto-generated method stub try{ message = et.gettext().tostring(); log.i("message posted", message); new registerme().execute(); }catch(exception e){ log.e("exception while getting message", e.getmessage().tostring()); } } }); b2.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { // todo auto-generated method stub startactivity(new intent(home.this, getmessage.class)); } }); } @override public boolean oncreateoptionsmenu(menu menu) { // inflate menu; adds items action bar if present. getmenuinflater().inflate(r.menu.activity_home, menu); return true; } class registerme extends asynctask<string, string, string>{ string message=null; public boolean workdone(string message){ boolean x=false; if(message == "done"){ x=true; } return x; } @override protected void onpreexecute(){ super.onpreexecute(); pdialog = new progressdialog(home.this); pdialog.setmessage("transaction in progress... \n have right remain \n silent & patient :)"); pdialog.setindeterminate(false); pdialog.setcancelable(true); pdialog.show(); } @override protected string doinbackground(string... args) { list<namevaluepair> params = new arraylist<namevaluepair>(); params.add(new basicnamevaluepair("message", message)); jsonobject json = jsonparser.makehttprequest(url_addmessage, "get", params); log.d("create response", json.tostring()); try{ int success = json.getint(tag_success); if(success == 1){ message = "done"; log.d("work done", "message added"); } else{ log.d("work done", "message not added"); } } catch(jsonexception e){ e.printstacktrace(); } return null; } protected void onpostexecute(string file_url){ pdialog.dismiss(); if(new registerme().workdone(message)){ toast.maketext(home.this, "message added successfully.",toast.length_long).show(); } else{ toast.maketext(home.this, "sorry there error in processing request, please try after time.",toast.length_long).show(); } } } }
