listview - Android O Beta Preview 3 - Lists and Adapters issues? -

i'm running latest developer preview of android o , i'm seeing following behaviours:

• i have various lists inside dialog fragments use custom adapters extend baseadapter. these no longer selectable on android o.

• i have other lists inside fragments (not dialog fragments) which
  use custom adapters extend arrayadapter<>. these work fine on android o.

• when try , change dialog fragment list adapters extend arrayadapter<>, lists still not selectable.

below sample wrote recreate problem i'm experiencing inside app. have activity creates dialog fragment has list inside. list adapter extends baseadapter. list unresponsive , onitemclicklistener never fired.

this pattern worked in app until android o.

has else experienced problem? i've had hunt around documentation , doesn't mention changes around adapters/lists.

thanks in advance help!

activity:

    public class mainactivity extends appcompatactivity {      list<string> wafilms = new arraylist<>();      @override     protected void oncreate(bundle savedinstancestate) {       super.oncreate(savedinstancestate);       setcontentview(r.layout.activity_main);       setuplist();        button button = (button) findviewbyid(r.id.launchbutton);       button.setonclicklistener(new view.onclicklistener() {        @override        public void onclick(view view) {           listdialogfragment ldf =listdialogfragment.getinstance(wafilms);           ldf.show(getfragmentmanager(), "listdialogfragment.");       }     });    }     private void setuplist() {       wafilms.add(0, "bottlerocket");       wafilms.add(1, "rushmore");       wafilms.add(2, "the royal tenenbaums");       wafilms.add(3, "the life aquatic");       wafilms.add(4, "the darjeeling limited");       wafilms.add(5, "fantastic mr fox");       wafilms.add(6, "moonrise kingdom");       wafilms.add(7, "the grand budapest hotel");      }    } 

dialog fragment:

public class listdialogfragment extends dialogfragment {    list<string> wafilms = new arraylist<>();    public static listdialogfragment getinstance(list<string> answeroptions) {     listdialogfragment f = new listdialogfragment();     f.wafilms = answeroptions;     return f;   }    @nonnull   @override   public dialog oncreatedialog(bundle savedinstancestate) {     listview list = (listview) view.inflate(getactivity(), r.layout.dialog_fragment_list, null);     list.setadapter(new simpleadapter(2, wafilms, getactivity()));     list.setonitemclicklistener(onclicklistener);      alertdialog.builder builder = new alertdialog.builder(getactivity());     builder.settitle("please pick film.");     builder.setview(list);     dialog d = builder.create();     d.setcanceledontouchoutside(false);     return d;   }    adapterview.onitemclicklistener onclicklistener = new adapterview.onitemclicklistener() {     @override     public void onitemclick(adapterview<?> adapterview, view view, int position, long l) {       string chosenoption = wafilms.get(position);       toast.maketext(getactivity(), "your chosen film is: " + chosenoption, toast.length_short).show();     }   }; } 

adapter:

public class simpleadapter extends baseadapter {    private list<string> items;   private context context;   private int selection;    public simpleadapter(int selection, list<string> items, context context) {     super();     this.items = items;     this.selection = selection;     this.context = context;   }    @override   public int getcount() {     return items.size();   }    @override   public object getitem(int i) {     return items.get(i);   }    @override   public long getitemid(int i) {     return i;   }    @override   public view getview(int position, view convertview, viewgroup parent) {     if (convertview == null)       convertview = ((layoutinflater) context.getsystemservice(context.layout_inflater_service)).inflate(r.layout.form_dialog_list_item, null);      textview text = convertview.findviewbyid(r.id.listtextview);     imageview star = convertview.findviewbyid(r.id.listselectionicon);      star.setvisibility(position == selection ? view.visible : view.gone);     text.settext(items.get(position));      return convertview;   }    public list<string> getitems() {     return items;   } }
