android - Remove Dynamically added layouts from listview extends base adapter -

here have number of layouts inflated, when length of ei.duedate.size() 0 views not removed.

i have search lots of didn't how can remove views listview.

i have inflated 5-6 child layouts when size goes 1-2 inflated views can not remove.

please me if guys have idea.

below you'll find adapter code:

   public class immunisationadapter extends baseadapter {      @override     public int getcount() {         // todo auto-generated method stub         return immumainarraylist.size();     }      @override     public object getitem(int position) {         // todo auto-generated method stub         return immumainarraylist.get(position);     }      @override     public long getitemid(int position) {         // todo auto-generated method stub         return position;     }      @override     public view getview(final int position, view view, viewgroup parent) {         // todo auto-generated method stub         viewholder holder = null;

you need take view recycling account. holder.layout viewgroup may have children in it, need removed first.

@override public view getview(final int position, view view, viewgroup parent) {     // todo auto-generated method stub     viewholder holder = null;      final immunimodel ei = immumainarraylist.get(position);     if (view == null) {         holder = new viewholder();         view = layoutinflater.from(getactivity()).inflate(r.layout.raw_main_immunisation, parent, false);         holder.layout = (viewgroup) view.findviewbyid(r.id.ll);         holder.imageview = (imageview) view.findviewbyid(r.id.optin);         holder.txt_count = (textviewplus)view.findviewbyid(r.id.txt_circle);         holder.mg_type = (imageview) view.findviewbyid(r.id.mg_type);         holder.txt_main = (textviewplus) view.findviewbyid(r.id.txt_main);         holder.txt_new_elder = (textviewplus) view.findviewbyid(r.id.txt_new_elder);         view.settag(holder);     } else {         holder = (viewholder) view.gettag();         holder.layout.removeallviews();     }      log.e("size of childimmunisation",ei.duedate.size()+"");     (int = 0; < ei.duedate.size(); i++) {          view chiledview = layoutinflater.from(getactivity()).inflate(r.layout.raw_child_immunisation, null);         viewgroup.layoutparams layoutparams = new viewgroup.layoutparams(layoutparams.wrap_content, layoutparams.wrap_content);         checkbox jabchk = (checkbox) chiledview.findviewbyid(r.id.chk);         textviewplus txt_date = (textviewplus) chiledview.findviewbyid(r.id.txt_date);         textviewplus txt_lbl = (textviewplus) chiledview.findviewbyid(r.id.text_admin);         jabchk.settext("jab " + (i+1));         chiledview.settag(i);         chiledview.setlayoutparams(layoutparams);         txt_date.settext(ei.duedate.get(i).due_on);          if (ei.duedate.get(i).status.equals("administered")) {             jabchk.setchecked(true);              txt_lbl.settext("administered on ");         } else if (ei.duedate.get(i).status.equals("planned")) {             jabchk.setchecked(false);             txt_lbl.settext("estimated due date  ");         }         holder.layout.addview(chiledview, i);         chiledview.setonclicklistener(new onclicklistener() {              @override             public void onclick(view v) {                 // todo auto-generated method stub                  int pos = (integer) v.gettag();                  intent intent = new intent(getactivity(), editjabimmunisationactivity.class);                 intent.putextra("pos", (pos+1) + "");                 intent.putextra("status", ei.duedate.get(pos).status);                 editor.putstring(utils.jabname, ei.name);                 editor.putstring(utils.jabid, ei.duedate.get(pos).id);                 editor.putstring(utils.jabdate, ei.duedate.get(pos).due_on);                 editor.commit();                 intent.putextra("location", ei.duedate.get(pos).jab_location);                 intent.putextra("type", ei.duedate.get(pos).jab_type);                 intent.putextra("note", ei.duedate.get(pos).note);                 intent.putextra("doc", ei.duedate.get(pos).doc_name);                 intent.putextra("facility", ei.duedate.get(pos).facility);                  startactivity(intent);                     getactivity().overridependingtransition(r.anim.slide_in_right, r.anim.slide_out_left);             }         });      }      holder.txt_main.settext(immumainarraylist.get(position).name);     if (immumainarraylist.get(position).category.equals("drops")) {         holder.mg_type.setimageresource(r.drawable.drop);     }else if (immumainarraylist.get(position).category.equals("injection")) {         holder.mg_type.setimageresource(r.drawable.syring);     }else if (immumainarraylist.get(position).category.contains("pill")) {         holder.mg_type.setimageresource(r.drawable.pill);     }     holder.imageview.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {             // todo auto-generated method stub             popupwindowdogs = popupwindow.popupwindowdogs(position);             popupwindowdogs.showasdropdown(v, -5, 0);         }     });     holder.txt_new_elder.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {             // todo auto-generated method stub             log.e("helof", immumainarraylist.get(position).vaccin_id);             try {                 addnewjab(immumainarraylist.get(position).vaccin_id, token);             } catch (jsonexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }         }     });     return view; } 

i showed quick , easy way. better way not call removeallviews(), you're looping through ei.duedate, call getchildat(i) see if raw_child_immunisation view there , use rather inflating new view. have use removeviews(start, count) clear vestigial raw_child_immunisation views @ end of loop.

here code changes strategy:

@override public view getview(final int position, view view, viewgroup parent) {     // todo auto-generated method stub     viewholder holder = null;     final immunimodel ei = immumainarraylist.get(position);     if (view == null) {         holder = new viewholder();         view = layoutinflater.from(getactivity()).inflate(r.layout.raw_main_immunisation, parent, false);         holder.layout = (viewgroup) view.findviewbyid(r.id.ll);         holder.imageview = (imageview) view.findviewbyid(r.id.optin);         holder.txt_count = (textviewplus)view.findviewbyid(r.id.txt_circle);         holder.mg_type = (imageview) view.findviewbyid(r.id.mg_type);         holder.txt_main = (textviewplus) view.findviewbyid(r.id.txt_main);         holder.txt_new_elder = (textviewplus) view.findviewbyid(r.id.txt_new_elder);         view.settag(holder);     } else {         holder = (viewholder) view.gettag();         int childcount = holder.layout.getchildcount();         if (childcount > ei.duedate.size()) {             // remove views             holder.layout.removeviews(ei.duedate.size(), childcount - ei.duedate.size());         }     }      log.e("size of childimmunisation",ei.duedate.size()+"");     (int = 0; < ei.duedate.size(); i++) {          // if view exists, use         view chiledview = holder.layout.getchildat(i);         if (chiledview == null) {             // otherwise create new view , add view group             chiledview = layoutinflater.from(getactivity()).inflate(r.layout.raw_child_immunisation, null);             holder.layout.addview(chiledview, i);         }         viewgroup.layoutparams layoutparams = new viewgroup.layoutparams(viewgroup.layoutparams.wrap_content, viewgroup.layoutparams.wrap_content);         checkbox jabchk = (checkbox) chiledview.findviewbyid(r.id.chk);         textviewplus txt_date = (textviewplus) chiledview.findviewbyid(r.id.txt_date);         textviewplus txt_lbl = (textviewplus) chiledview.findviewbyid(r.id.text_admin);         jabchk.settext("jab " + (i+1));         chiledview.settag(i);         chiledview.setlayoutparams(layoutparams);         txt_date.settext(ei.duedate.get(i).due_on);          if (ei.duedate.get(i).status.equals("administered")) {             jabchk.setchecked(true);              txt_lbl.settext("administered on ");         } else if (ei.duedate.get(i).status.equals("planned")) {             jabchk.setchecked(false);             txt_lbl.settext("estimated due date  ");         }         chiledview.setonclicklistener(new view.onclicklistener() {         .         .         .
