java - Lost item background color when scrolling listview -

-

i tried used solutions stackoverflow, without succesfull. so, set background color item after click - working. after scrolling (when item out off screen) , scrolling (item in screen), item lost background color. here part of code:

public class rowadapter extends arrayadapter<filerow> { private final activity context; private final list<filerow> list;  public rowadapter(activity context, list<filerow> list) {     super(context, r.layout.browser_row, list);     this.context = context;     this.list = list; }  @override public view getview(int position, view convertview, viewgroup parent) {         view v = super.getview(position, convertview, parent);          layoutinflater inflator = context.getlayoutinflater();         convertview = inflator.inflate(r.layout.browser_row, null);          textview textview = (textview)convertview;         textview.settext(list.get(position).getname());         if (!list.get(position).getname().contains("/")) {             textview.setpadding(5, 5, 5, 5);             textview.setcompounddrawableswithintrinsicbounds(0,0,0,0);               }         (int i=0; i<browserfiles.selecteditems.size(); i++) {             if (browserfiles.selecteditems.get(i).getposition() == position) {                 v.setbackgroundcolor(color.rgb(255, 165, 0));                 break;             }         }      return convertview; }

}

public class browserfiles extends listactivity implements onitemclicklistener {  private string lastdir = "/"; private list<filerow> items = null; public static list<filerow> selecteditems;    @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      setcontentview(r.layout.browser_files);          listview lv = (listview) findviewbyid(android.r.id.list);     lv.setonitemclicklistener(this);     intent = getintent();     lastdir = i.getstringextra("lastdir");      getdir(lastdir);     selecteditems = new arraylist<filerow>(); }  @override public void onitemclick(adapterview<?> parent, view view, int position, long id) {     textview tv = (textview)view;     //jedna se o soubor     if (tv.gettext().tostring().tolowercase(locale.english).endswith("mp3")) {         string item = lastdir + tv.gettext().tostring();          int isinlist = -1;         (int i=0; < selecteditems.size(); i++) {             if (selecteditems.get(i).getname().comparetoignorecase(item) == 0) {                 isinlist = i;                 break;             }         }          if (isinlist != -1) {             selecteditems.get(isinlist).setselected(false);             selecteditems.remove(isinlist);             parent.getchildat(position).setselected(false);             parent.getchildat(position).setbackgroundcolor(color.transparent);         }         else {             selecteditems.add(new filerow(item, true, position));             parent.getchildat(position).setselected(true);                           parent.getchildat(position).setbackgroundcolor(color.rgb(255, 165, 0));         }                            }     //jedna se o adresar     else {         getdir(lastdir.compareto("/") == 0 ? lastdir + tv.gettext().tostring() : lastdir + "/" + tv.gettext().tostring());     }     }

i found solutions. add 2 lines:

for (int i=0; i<browserfiles.selecteditems.size(); i++) {             if (browserfiles.selecteditems.get(i).getposition() == position) {                  v.setbackgroundcolor(color.rgb(255, 165, 0));                 if (convertview != null)                     convertview.setbackgroundcolor(color.rgb(255, 165, 0));                 break;             }         }
