java - Saving and restoring an ArrayDeque onSaveInstanceState -


i working on video app thats uses arraydeque store our history of videos viewed, using push, pop. works i'm looking clean way of saving , restoring arraydeque

private deque<programmodel> mvideohistory = new arraydeque<>();

i save list saving arraylist.

@override public void onsaveinstancestate(final bundle outstate) {     // save history     arraylist<programmodel> history = new arraylist<>();     (programmodel program : mvideohistory) {         history.add(program);     }     outstate.putparcelablearraylist("videohistory", history); }

then restore it

if (savedinstancestate != null) {     // restore history     arraylist<programmodel> history =             savedinstancestate.getparcelablearraylist("videohistory");     mvideohistory = new arraydeque<>(history); }

can done in more efficient/cleaner way this?

ive tried outstate.putserializable("videohistory", mvideohistory.toarray()); restoring caused me problems.

you can this:

outstate.putserializable("videohistory", (arraydeque<programmodel>) mvideohistory);

cast again when restoring.

hope helps
