import java.text.simpledateformat; import java.util.calendar; import java.util.date;  import android.annotation.suppresslint; import android.app.alertdialog; import android.app.dialog; import android.content.contenturis; import android.content.dialoginterface; import android.database.cursor; import android.os.bundle; import android.os.handler; import android.support.v4.app.dialogfragment; import android.support.v4.app.loadermanager.loadercallbacks; import android.support.v4.content.cursorloader; import android.support.v4.content.loader;   @suppresslint("simpledateformat")  public class birthdaydetailsmessage extends dialogfragment implements loadercallbacks<cursor> {      static string date_format;     static final string calendar = "calendar";      private long mrowid;     private string mname;     private string mdate;     private boolean myearknown;     private string mage;     private calendar mcalendar;       @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);          mcalendar = calendar.getinstance();                  date_format = prefdateformat.getprefdateformat(getactivity());          bundle arguments = getarguments();          mrowid = arguments.getlong(reminderprovider.column_rowid);           getloadermanager().initloader(0, null, this);       }      @override     public dialog oncreatedialog(bundle savedinstancestate){             alertdialog.builder builder = new alertdialog.builder(getactivity());          builder.setmessage("birthday: "+ mdate +"\n\n"+"age: "+ mage)         .settitle(mname)         .setcancelable(false)         .setpositivebutton("ok",                 new dialoginterface.onclicklistener() {                      @override                     public void onclick(dialoginterface dialog, int which) {                                             dialog.cancel();                         }                                });          return builder.create();     }      @override     public loader<cursor> oncreateloader(int id, bundle args) {         return new cursorloader(getactivity(), contenturis.withappendedid(                 reminderprovider.content_uri, mrowid), null, null, null, null);     }      @override     public void onloadfinished(loader<cursor> loader, cursor reminder) {          if (reminder.getcount() == 0) {             new handler().post(new runnable() {                 @override                 public void run() {                     ((onfinisheditor) getactivity()).finisheditor();                 }             });             return;         }          mname = reminder.getstring(reminder                 .getcolumnindexorthrow(reminderprovider.column_name));          myearknown = (reminder.getint(reminder                 .getcolumnindexorthrow(reminderprovider.column_year))==0? false:true);          long dateinmillis = reminder.getlong(reminder                 .getcolumnindexorthrow(reminderprovider.column_date));         date date = new date(dateinmillis);         mcalendar.settime(date);           simpledateformat dateformat = new simpledateformat(date_format);         mdate = dateformat.format(mcalendar.gettime());          if (myearknown == true){             mage = string.valueof(getdiffyears.getdiffyears(mcalendar));         }else{             mage = "age not known";         }              }      @override     public void onloaderreset(loader<cursor> arg0) {         // nothing reset fragment     }     } 

edit:

i removed oncreatedialog method , used following view instead

public view oncreateview(layoutinflater inflater, viewgroup container,         bundle savedinstancestate) {     view v = inflater.inflate(r.layout.dialog_fragment, container,             false);     getdialog().settitle("name");         date = (textview) v.findviewbyid(r.id.date);     age = (textview) v.findviewbyid(r.id.age);       getloadermanager().initloader(0, null, this);      return v; }  private void updatevalues() {     getdialog().settitle(mname);     date.settext("geburtstag: "+ mdate);     age.settext("alter: " + mage);       } 

in included updatevalues() in onloadfinished, , created layout xml message body...this way seems work properly.

what want use call method loader create dialog. not put loader in dialog class, either in calling class or separate class. call/create dialog in onloadfinished. implementation similar asynctask.

alternately, create dialog default text, , retain reference in calling class. in onloadfinished update values of dialog. i'm pretty sure 1 work, haven't tested it.
