android - how to change recyclerview item's layout from outside? -


i have recyclerview, has button , edittext. have button outside of recyclerview. on click outside button, want button in recyclerview toggles between hide , show. how that?

i have tried send boolean parameter meditflag recycleradapter, toogle meditflag, , notify adapter data has changed. doesn't work.

mcurrentorderrecycleradapter = new currentorderrecycleradapter(this, meditflag);     rvorder.setadapter(mcurrentorderrecycleradapter);  rleditorderlist.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             meditflag = !meditflag;             mcurrentorderrecycleradapter.notifydatasetchanged();             if (meditflag) {                 iveditorderlist.setimageresource(r.drawable.order_edit_true);                 tveditorderlist.settext(r.string.order_edit_flag_true);             } else {                 iveditorderlist.setimageresource(r.drawable.order_edit_false);                 tveditorderlist.settext(r.string.order_edit_flag_false);             }         }     });  @override public void onbindviewholder(orderrecyclerviewholder holder, final int position) {      if(editflag) {         holder.rlleftitemrvorder.setvisibility(view.visible);     } else {         holder.rlleftitemrvorder.setvisibility(view.gone);     }      holder.tvnumitemrvorder.settext(position + "x");     holder.tvdesitemrvorder.settext("holder.ivfooditemrvorder.setimageresource(r.drawable.drawer_menu)");     holder.ivfooditemrvorder.setimageresource(r.drawable.drawer_menu);  }

you have achieve adapter layer.

the button outside recyclerview has update item inside adapter (for example boolean).
notify change update (for example notifyitemchanged method) recyclerview

somenthing like:

rleditorderlist.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             //update item inside adapter             myobject obj = madapter.getitem(position);             obj.myboolean= true;             madapter.notifyitemchanged(position);         }     });

with adapter like:

    public class myadapter extends recyclerview.adapter<recyclerview.viewholder> {          private arraylist<myobject> mdataset;          @override         public void onbindviewholder(viewholder holder, int position) {             //get item in adapter             myobject obj = getitem(position);             if(obj.myboolean)                holder.mbuttonview.setvisibile(view.visible);             else                holder.mbuttonview.setvisibile(view.gone);         }      }
