searchable spinner not working in Android Java -


i have java.lang.unsupportedoperationexception @ iterator .remove() believe considered safe , think code "ok" can me?

    final list<string> livelist = arrays.aslist((string[]) button.getitems().toarray()); //create mutable list<string> button.getitems() list<string>      final premspinner dropdown = new premspinner(this); //spinner (eg: "dropdown") of options     dropdown.setlayoutparams(col);     final arrayadapter<string> dataadapter = new arrayadapter<string>(this, android.r.layout.simple_spinner_item, livelist);        //      <---+     dataadapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item);                                             //          |     dropdown.setpadding(45, 15, 45, 15);                //                                                                                      |     dropdown.setadapter(dataadapter);                   //the way [populate] `dropdown(spinner)` via `adapter` , list<string>   |              final edittext partsearcher = new edittext(this);     partsearcher.setlayoutparams(col);     partsearcher.addtextchangedlistener(new textwatcher() {         public void aftertextchanged(editable s) {             log.w("typing",s.tostring());             iterator<string> iter = livelist.iterator();              while (iter.hasnext()) {                 if (!iter.next().contains(s)) {                     iter.remove();  //<--the unsupportedoperationexception here                 }             }             dataadapter.notifydatasetchanged();         }         public void beforetextchanged(charsequence s, int start, int count, int after) {}         public void ontextchanged(charsequence s, int start, int before, int count) {}     });

then add them table

    tr = new tablerow(this);             tr.setlayoutparams(lp);     tr.addview(partsearcher);     table.addview(tr, new tablelayout.layoutparams(layoutparams.wrap_content, layoutparams.wrap_content));      tr = new tablerow(this);         tr.setlayoutparams(lp);     tr.addview(dropdown);            table.addview(tr, new tablelayout.layoutparams(layoutparams.wrap_content, layoutparams.wrap_content)); //this makes fat enough

the code designed portable people want text search in spinner, there lot of interest in dynamic spinner no solid workable code examples, hoping make 1 blog article, can't figure out!

the iterator in case based on list not support remove();

you need pass in actual object or index of object want remove.
