android - Is it possible to send an object from a fragment to another fragment? -


the object want send fragment fragment "post". demandfragment consist of listview consist of items post objects.

i need send selected item listview, in case postarraylist.get(position), selectedpostfragment.

i've tried bundle not working...

does know how fix this?

demandfragment:

public class demandfragment extends fragment {  listview lv; arrayadapter adapter; arraylist<post> postarraylist; private edittext editsearch;  @nullable @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     view rootview = inflater.inflate(r.layout.fragment_demand, container, false);      if(rootview != null){         lv = (listview) rootview.findviewbyid(r.id.listdemand);          editsearch = (edittext) rootview.findviewbyid(r.id.search_post);          lv.setonitemclicklistener(new adapterview.onitemclicklistener() {             @override             public void onitemclick(adapterview<?> parent, view view, int position, long id) {                 // clicked on item show post                 post selectedpost = postarraylist.get(position);                 bundle bundle = new bundle();                 bundle.putparcelable("data", (parcelable) selectedpost);                 fragmentmanager fm = getactivity().getfragmentmanager();                 fragment fragment = new rang.afterflight.fragments.selectedpostfragment();                 fragment.setarguments(bundle);                 fm.begintransaction().replace(r.id.content_main, fragment).commit();             }         });     }     searchpost();     return rootview; }  public void searchpost(){     editsearch.addtextchangedlistener(new textwatcher() {         @override         public void beforetextchanged(charsequence s, int start, int count, int after) {          }          @override         public void ontextchanged(charsequence s, int start, int before, int count) {             adapter.getfilter().filter(s);         }          @override         public void aftertextchanged(editable s) {          }     }); }   @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      sethasoptionsmenu(true);      parsequery<parseobject> query = parsequery.getquery("post");      postarraylist = new arraylist<post>();      query.findinbackground(new findcallback<parseobject>() {         public void done(list<parseobject> postlist, parseexception e) {             if (e == null) {                 (parseobject object : postlist) {                     post newpost = new post();                      newpost.setairportparse((string) object.get("airport"));                     newpost.setdateparse((string) object.get("date"));                     newpost.settimeparse((string) object.get("time"));                     newpost.setpersonsparse((string) object.get("persons"));                     newpost.setaddressparse((string) object.get("address"));                     newpost.setflightnrparse((string) object.get("address"));                     newpost.setusername((string) object.get("username"));                     newpost.setimagefile((parsefile) object.get("profilepic"));                      postarraylist.add(newpost);                 }                 adapter = new listviewadapter(getactivity(), r.layout.item_cardview, postarraylist);                 lv.setadapter(adapter);             }         }     }); }

}

selectedpostfragment:

public class selectedpostfragment extends fragment { textview airportpost, datepost, timepost, personspost, addresspost,         flightnrpost, postedbypost, contactpost;   imageview iv;  @nullable @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     view rootview = inflater.inflate(r.layout.fragment_selectedpost, container, false);      airportpost = (textview) rootview.findviewbyid(r.id.airport_post);     datepost = (textview) rootview.findviewbyid(r.id.date_post);     timepost = (textview) rootview.findviewbyid(r.id.time_post);     personspost = (textview) rootview.findviewbyid(r.id.persons_post);     addresspost = (textview) rootview.findviewbyid(r.id.address_post);     flightnrpost = (textview) rootview.findviewbyid(r.id.flightnr_post);     postedbypost = (textview) rootview.findviewbyid(r.id.postedby_post);     contactpost = (textview) rootview.findviewbyid(r.id.contact_post);      post selectedpost = getarguments().getparcelable("object");     string s = (string) selectedpost.get("airport");     log.d("airport name", s);      return rootview; }

}

post:

@parseclassname("post") public class post extends parseobject implements serializable {      public post(){         super();     }      public string getid(){         return getstring("objectid");     }      public void setid(string id){         put("objectid", id);     }      //////////      public string getusername(){         return getstring("username");     }      public void setusername(string username){         put("username", username);     }        public string getairportparse(){         return getstring("airport");     }      public void setairportparse(string airport){         put("airport", airport);     }      //////////       public string getdateparse(){         return getstring("date");     }      public void setdateparse(string date){         put("date", date);     }       //////////       public string gettimeparse(){         return getstring("time");     }      public void settimeparse(string time){         put("time", time);     }       //////////       public string getpersonsparse(){         return getstring("persons");     }      public void setpersonsparse(string persons){         put("persons", persons);     }       //////////       public string getaddressparse(){         return getstring("address");     }      public void setaddressparse(string address){         put("address", address);     }      public string getflightnrparse(){         return getstring("flightnr");     }      public void setflightnrparse(string flightnr){         put("flightnr", flightnr);     }       public bitmap getimagefile(){         bitmap bmp = null;         parsefile image = getparsefile("profilepic");         if(image != null){             try {                 byte[] data = image.getdata();                 bmp = bitmapfactory.decodebytearray(data, 0, data.length);             } catch (parseexception e) {                 e.printstacktrace();                 }         }         return bmp;     }      public void setimagefile(parsefile file) {         if (file != null) {             put("profilepic", file);         }     } }

i believe post class needs implement parcelable pass in bundle between fragments putparcelable().

check out: parcelable.

this great example.

basic implementation:

public class post extends parseobject implements serializable, parcelable {     ...      public int describecontents() {         return 0;     }      public void writetoparcel(parcel out, int flags) {         out.writestring(getid());         out.writesring(getusername());         ...     }      public static final parcelable.creator<post> creator         = new parcelable.creator<post>() {             public post createfromparcel(parcel in) {                 return new post(in);             }              public post[] newarray(int size) {                 return new post[size];             }     };      private post(parcel in) {         // items must read in order written.         setid(in.readstring());         setusername(in.readstring());         ...     } }

try on size, hope helps.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
