java - Passing data from BroadCastRecevier to activity -

i have sms reader application , showing senderno , message body custom listview. incoming messages have registered broadcast receiver , populating listview.

whenever new message coming in broadcast receiver able want data passed onto activity.

the code snippets :

mainactvity.java

public class mainsmsactivity extends activity{     private listview smslist;     smsadapter smsadapter;     private smsdao smsdao;     private list<smsdao> smsdatalist;       @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_sms_demo);         smsdatalist = new arraylist<smsdao>();         intent intent = new intent();         intent.setaction("com.mobile.sms.incomingsms");         sendbroadcast(intent);         populatesms();    }  public void populatesms(){         uri inboxuri = uri.parse("content://sms/inbox");         string[] reqcols = new string[] { "_id", "address", "body", "date" };         contentresolver cr = getcontentresolver();         cursor cursor = cr.query(inboxuri, reqcols, null, null, null);         smsdatalist.clear();          (cursor.movetofirst(); !cursor.isafterlast(); cursor.movetonext()) {             smsdao = new smsdao();             smsdao.setmessagebody(cursor.getstring(1));             smsdao.setsenderno(cursor.getstring(2));             smsdao.setmessagetime(cursor.getlong(3));             smsdatalist.add(smsdao);           }         smsadapter = new smsadapter(this,smsdatalist);         smslist.setadapter(smsadapter);         smsadapter.notifydatasetchanged();         cursor.close(); } } 

incomingsms.java

public class incomingsms extends broadcastreceiver {     final smsmanager sms = smsmanager.getdefault();     public void onreceive(context context, intent intent) {         final bundle bundle = intent.getextras();         try {             if (bundle != null) {                 final object[] pdusobj = (object[]) bundle.get("pdus");                 (int = 0; < pdusobj.length; i++) {                     smsmessage currentmessage = smsmessage.createfrompdu((byte[]) pdusobj[i]);                     string phonenumber = currentmessage.getdisplayoriginatingaddress();                      string sendernum = phonenumber;                     string message = currentmessage.getdisplaymessagebody();                     int duration = toast.length_long;  // here want send message body main activity class                     toast toast = toast.maketext(context,                             "sendernum: " + sendernum + ", message: " + message, duration);                     toast.show();                 } // end loop             } // bundle null         } catch (exception e) {             log.e("smsreceiver", "exception smsreceiver" + e);         }     } 

i able receive messages intially list view want listview should automatically updated new message arrives.

in broadcasereceiver this: (use intent)

public class smsreceiver extends broadcastreceiver {  public static final string notification = "receiver_sms"; @override public void onreceive(context context, intent intent) {      log.i("onreceive methode", "new sms comming");      bundle mybundle = intent.getextras();      smsmessage[] messages = null;     string strmessage = "", address = "";     abortbroadcast();     if (mybundle != null) {         // message in pdus format(protocol description unit)         object[] pdus = (object[]) mybundle.get("pdus");         // create array of messages         messages = new smsmessage[pdus.length];         log.i("onreceive methode", "new sms comming");         (int = 0; < messages.length; i++) {             // create smsmessage raw pdu.             messages[i] = smsmessage.createfrompdu((byte[]) pdus[i]);             // originating address (sender) of sms message in             // string form or null if unavailable             address = messages[i].getoriginatingaddress();              // message body string, if exists , text             // based.             strmessage += messages[i].getmessagebody();             strmessage += "\n";         }          // show message in toast     }         // need         intent broadcast = new intent(notification);         broadcast.putextra("data", strmessage);         localbroadcastmanager.getinstance(context).sendbroadcast(broadcast);  } 

and register ur receiver in ur activity

public broadcastreceiver receiver = new broadcastreceiver() {      @override     public void onreceive(context context, intent intent) {         log.e(tag, "sms received.");         // intent = getintent();         bundle b = intent.getbundleextra("sms");         // string bun = b.getstring("mydata");         log.i(tag, "bundle:  " + b);         string str = intent.getstringextra("data");          parsesmsdata(str);     } }; 

and in onresume():

@override protected void onresume() {     super.onresume();     localbroadcastmanager.getinstance(this).registerreceiver(receiver,             new intentfilter(smsreceiver.notification)); } 

and in ondestroy() must unregister receiver this:

@override protected void ondestroy() {     // unregister since activity closed.     localbroadcastmanager.getinstance(this).unregisterreceiver(receiver);     super.ondestroy(); } 

and don't forget add in ur manifest file in application tag:

 <receiver android:name=".smsbroadcastreceiver">         <intent-filter>             <action android:name="android.provider.telephony.sms_received"></action>         </intent-filter>     </receiver>
