java - How I can get the contact name from the android (CallLog.Calls.CONTENT_URI) table? -

i new android , working on application need outgoing call logs, number, call duration , name of contact. question can name , number of outgoing call calllog.calls.content_uri table of android system or need read separate table , map it. below code. in advance.

 private string getcalldetails() {          stringbuffer sb = new stringbuffer();         // cursor managedcursor =         // getcontentresolver().query(calllog.calls.content_uri, null,         // null, null, null);          cursor managedcursor = getcontentresolver().query(calllog.calls.content_uri, null, calllog.calls.date + ">?",                 new string[] { string.valueof("1451586601000") }, calllog.calls.number + " asc");         int number = managedcursor.getcolumnindex(calllog.calls.number);         int type = managedcursor.getcolumnindex(calllog.calls.type);         int date = managedcursor.getcolumnindex(calllog.calls.date);         int duration = managedcursor.getcolumnindex(calllog.calls.duration);         int name = managedcursor.getcolumnindex(calllog.calls.cached_name);         // int geocodecolumn =         // managedcursor.getcolumnindex(calllog.calls.geocoded_location);          // sb.append("call details :");         while (managedcursor.movetonext()) {             string phnumber = managedcursor.getstring(number);             string calltype = managedcursor.getstring(type);             string calldate = managedcursor.getstring(date);             string callername = managedcursor.getstring(name);             // long calldate_timestamp= long.parselong(calldate);             // long temp_time = 1451586601000l;             // if(calldate_timestamp>temp_time){             // string geocode = managedcursor.getstring(geocodecolumn);             date calldaytime = new date(long.valueof(calldate));             string callduration = managedcursor.getstring(duration);             string dir = null;             int dircode = integer.parseint(calltype);             switch (dircode) {             case calllog.calls.outgoing_type:                 dir = "outgoing";                 int total_call_duration = integer.parseint(callduration);                 total_time = total_time + total_call_duration;                 mycontact dialedcontact = new mycontact();                 dialedcontact.setphonenumber(long.parselong(phnumber));                 dialedcontact.setcallduration(integer.parseint(callduration));                 // dialedcontact.se                  sb.append("\nphone number:--- " + phnumber + " \ncalltype:--- "                  + dir + " \ncall date:--- " + calldaytime                  + " \ncall duration in sec :--- " + callduration+ " \ngeocode: " );                  sb.append("\n----------------------------------");                  break;              case calllog.calls.incoming_type:                 dir = "incoming";                 break;              case calllog.calls.missed_type:                 dir = "missed";                 break;             }         }          // }         managedcursor.close();     //  sb.append("" + total_time / 60);// call duration in minute         return sb.tostring();      } 

you need:

1) permissions

add permission read contacts data application manifest.

2) calling contact picker

within activity, create intent asks system find activity can perform pick action items in contacts uri.

intent intent = new intent(intent.action_pick, contactscontract.contacts.content_uri); call startactivityforresult, passing in intent (and request code integer, pick_contact in example). cause android launch activity that's registered support action_pick on people.content_uri, return activity when selection made (or canceled).

startactivityforresult(intent, pick_contact); 

3) listening result

also in activity, override onactivityresult method listen return 'select contact' activity launched in step 2. should check returned request code matches value you're expecting, , result code result_ok.

you can uri of selected contact calling getdata() on data intent parameter. name of selected contact need use uri create new query , extract name returned cursor.

@override public void onactivityresult(int reqcode, int resultcode, intent data) {   super.onactivityresult(reqcode, resultcode, data);  switch (reqcode) { case (pick_contact) : if (resultcode == activity.result_ok) { uri contactdata = data.getdata(); cursor c =  getcontentresolver().query(contactdata, null, null, null, null); if (c.movetofirst()) { string name = c.getstring(c.getcolumnindex(contactscontract.contacts.display_name)); // todo whatever want selected contact name.      } } break;     } }
