java - ImageArray not populating when the fields are passed to it -

so have imagearray finds 17 fields. not populate them array @ end. says image array empty. debugger shows log populated 17 fields database. array fails include them @

imagearray.add(rn); 

java oncreate

@override protected void oncreate(bundle savedinstancestate) {     requestwindowfeature(window.feature_no_title);     getwindow().setflags(windowmanager.layoutparams.flag_fullscreen,             windowmanager.layoutparams.flag_fullscreen);     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_myreceipts);      receiptsoperations ro = new receiptsoperations(this);      list<receipt> receipts = ro.getreceipts();     for(receipt rn : receipts){         string log = "receiptid:" + rn.getreceiptid() + "receipturi:" + rn.getreceipturi();          log.d("result: ", log);         imagearray.add(rn);      } 

receipt list initialised

public list<receipt>getreceipts() {     // code retrieve images database.     list<receipt> receiptlist = new arraylist<receipt>();     string selectquery = "select* receipts_table order receipt_id";     // check rows , add list.     sqlitedatabase db = this.getwritabledatabase();     cursor cursor = db.rawquery(selectquery,null);     if(cursor.movetofirst())     {                 {             receipt receipt = new receipt();             receipt.setreceiptid(new string(cursor.getstring(0)));             receipt.setreceipturi(new string(cursor.getstring(2)));             receiptlist.add(receipt);         }         while(cursor.movetonext());     }      db.close();     return receiptlist; }
