android - How to bring contacts up to send a text -

i have application defines word , sends definition via sms. problem user has type in phone number. thinking perhaps app should bring contacts list, user can select contact user can send message contact. here code smsactivity:

public class smsactivity extends activity  {  string apptag = "smstransmit";  //private static strings: private final static string sent = "sms_sent"; private final static string delivered = "sms_delivered";  private button btnsend; private button btnexit;  private button btnclear; private edittext etphonenumber; private edittext etusermessage;  //private broadcastreceiver member variables: private smsdispatchreceiver sendreceiver = null; private smsreceiptreceiver receiptreceiver = null;   @override public void oncreate(bundle savedinstancestate)  {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_sms);      bundle extras = getintent().getextras();     string definiedword = null;      if (extras != null)      {         definiedword = extras.getstring("definition");      }     else      {         definiedword = "none";      }      log.d("recievedagain", definiedword);     log.v(apptag, "mainactivity: oncreate() called");      //create new broadcast receiver sending sms     sendreceiver = new smsdispatchreceiver();      //create new broadcast receiver receipt of send sms      receiptreceiver = new smsreceiptreceiver();      //register new receivers (as new intentfiler() objects):     registerreceiver(sendreceiver, new intentfilter(sent));     registerreceiver(receiptreceiver, new intentfilter(delivered));      //get view objects:     btnsend = (button) findviewbyid(r.id.btnsend);     btnclear = (button) findviewbyid(r.id.btnclear);     btnexit = (button) findviewbyid(r.id.btnexit);     etphonenumber = (edittext) findviewbyid(r.id.etnumber);     etusermessage = (edittext) findviewbyid(r.id.etmessage);      //disable soft keyboard (this in general):     inputmethodmanager inmethodmgr =                                                                (inputmethodmanager)getsystemservice(context.input_method_service);     inmethodmgr.hidesoftinputfrominputmethod(etphonenumber.getwindowtoken(), 0);     inmethodmgr.hidesoftinputfrominputmethod(etusermessage.getwindowtoken(), 0);      //set hint edittext boxes:     etphonenumber.sethint("enter phone number (default = 5556)");     etusermessage.sethint(definiedword);      //create click event listener send button (onclicklistener):     btnsend.setonclicklistener(new view.onclicklistener()      {          @override         public void onclick(view v)          {              string strmessage = null;             string strnumber = null;              //get phone number edittext box:             strnumber = etphonenumber.gettext().tostring();              //check phone number:             if (strnumber.length() <= 0)              {                  //no phone number, default (5556):                 strnumber = smsproperties.getphonenumber();             }               //get message edittext box:             strmessage = etusermessage.gettext().tostring();              //check message contains content:             if (strmessage.length() > 0)              {                  //sent sms phone number                  sendsms(strnumber, strmessage);                } else              {                  //warn user , reset focus / hint:                 toast.maketext(getbasecontext(), "no message text! please      enter text sms!!", toast.length_short).show();                 etusermessage.sethint("enter message text here . . . ");                 etusermessage.requestfocus();              }          }     });        //create click event listener clear button (onclicklistener):     btnclear.setonclicklistener(new view.onclicklistener() {          @override         public void onclick(view v) {              //clear appropriate edittext box:             if (etusermessage.isfocused()) {                  //clear text in user message edittext box:                 etusermessage.settext("");                  //set hint in user message edittext box:                 etusermessage.sethint("enter message text here . . . ");              } else if (etphonenumber.isfocused()) {                  //clear text in phone number edittext box:                 etphonenumber.settext("");                  //set hint in phone number edittext box:                 etphonenumber.sethint("enter phone number (default = 5556)");             }         }     });        //create click event listener exit button (onclicklistener):     btnexit.setonclicklistener(new view.onclicklistener()     {          @override         public void onclick(view v)          {              //finish activity:             //note: main activity cause ondestroy() called!             finish();         }     });  }    //method send sms message device: private void sendsms(string strnum, string strmsg) {                        //todo: create pending intent smsdistatchreceiver (sent):     pendingintent sentpi = pendingintent.getbroadcast(this, 0, new intent("sent"), 0);      //todo: create pending intent smsreceiptreceiver (delivered):     pendingintent deliveredpi = pendingintent.getbroadcast(this, 0, new intent("delivered"), 0);     //get default smsmanager object:     smsmanager smsmgr = smsmanager.getdefault();      //todo: send sms using smsmanager:       smsmgr.sendtextmessage(strnum, null, strmsg, sentpi, deliveredpi);   } 

consider contact button bring contact list

contact.setonclicklistener(new view.onclicklistener() {                          @override             public void onclick(view g) {                 intent q = new intent(intent.action_pick, contacts.content_uri);                 startactivityforresult(q, 1001);                }         }); 

and handle result (which referenced 1001) use this:

public void onactivityresult(int reqcode, int resultcode, intent data) {           super.onactivityresult(reqcode, resultcode, data);            if (resultcode == activity.result_ok) {               // getting uri result further working             uri contactdata = data.getdata();             cursor c =  managedquery(contactdata, null, null, null, null);              if (c.movetofirst()) {                 string  id =c.getstring(c.getcolumnindexorthrow(contactscontract.contacts._id));                string hasphone =c.getstring(c.getcolumnindex(contactscontract.contacts.has_phone_number));                  if (hasphone.equalsignorecase("1")) {               cursor phones = getcontentresolver().query(                                contactscontract.commondatakinds.phone.content_uri,null,                                contactscontract.commondatakinds.phone.contact_id +" = "+ id,                                null, null);                     phones.movetofirst();                       //this string hold contact number                       string cnumber = phones.getstring(phones.getcolumnindex("data1"));                       //this string hold contact name                       string cname = c.getstring(c.getcolumnindexorthrow(contactscontract.contacts.display_name));                    }              }}          }
