android - Creating SearchBox in listView -
i have created "search" box in android. when try search not showing updated value in list. value coming in list search related value not changing. here snapshot:
if enter "ab" it's working fine, when putting "s", it's showing first listview item this:
here fragment class using addtextchangelistener:
etsearchuser.addtextchangedlistener(new textwatcher() { @override public void beforetextchanged(charsequence charsequence, int i, int i1, int i2) { } @override public void ontextchanged(charsequence charsequence, int i, int i1, int i2) { if (i2<i1){ adapter.resetdata(); } adapter.getfilter().filter(charsequence); } @override public void aftertextchanged(editable editable) { } }); here adapter class:
public class removeuseradapter extends baseadapter implements filterable { private arraylist<usermodel> listcontent; private arraylist<usermodel> searchlist; context context; private filter planetfilter; usermodel content, content1; layoutinflater inflater; public removeuseradapter(context context, arraylist listcontent) { this.context = context; this.listcontent = listcontent; this.searchlist = listcontent; inflater = layoutinflater.from(context); } @override public int getcount() { return listcontent.size(); } @override public object getitem(int i) { return listcontent.get(i); } @override public long getitemid(int i) { return listcontent.get(i).hashcode(); } class viewholder { private textview tvemail, tvuserid; private checkbox checkbox; } @override public view getview(int i, view view, viewgroup viewgroup) { final viewholder viewholder, viewholder1; if (view == null) { layoutinflater inflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service); view = inflater.inflate(r.layout.remove_user_adapter, null); viewholder = new viewholder(); viewholder.tvemail = (textview) view.findviewbyid(r.id.tvemailuser); viewholder.tvuserid = (textview) view.findviewbyid(r.id.tvusergroup); viewholder.checkbox = (checkbox) view.findviewbyid(r.id.checkbox); viewholder.checkbox.setvisibility(view.invisible); view.settag(viewholder); } else { viewholder = (viewholder) view.gettag(); } content = (usermodel) listcontent.get(i); content = (usermodel) searchlist.get(i); //log.i("@@@",content.getemail()+" email"); viewholder.tvemail.settext(content.getemail()); viewholder.tvuserid.settext(content.getusergroup()); return view; } public void resetdata() { listcontent = searchlist; } @override public filter getfilter() { filter filter = new filter() { @override protected void publishresults(charsequence charsequence, filterresults result) { listcontent = (arraylist<usermodel>) result.values; notifydatasetchanged(); } @override protected filterresults performfiltering(charsequence constraint) { filterresults results = new filterresults(); arraylist<usermodel> filteredarrlist = new arraylist<usermodel>(); if (searchlist == null) { searchlist = new arraylist<usermodel>(listcontent); } if (constraint == null || constraint.length() == 0) { // set original result return results.count = searchlist.size(); results.values = searchlist; } else { constraint = constraint.tostring().tolowercase(); (int = 0; < searchlist.size(); i++) { content = (usermodel) searchlist.get(i); string data = content.getemail(); string user = content.getuserid(); if (data.tolowercase().startswith(constraint.tostring())) { filteredarrlist.add(new usermodel(data, user)); } } results.count = filteredarrlist.size(); results.values = filteredarrlist; } return results; } }; return filter; } }
for search using simple edittext.
and 1 more thing it's searching first letter of gmail. want make search randomly.
for example: abc@gmail.com there, if enter in search box "gmail" should show result.
here usermodel class:
public class usermodel { private string usergroup; private string name; private string email; private string phone; private string password; private string userid; public usermodel(string email, string usergroup) { super(); this.email = email; this.usergroup = usergroup; } public usermodel(){} public string getuserid() { return userid; } public void setuserid(string userid) { this.userid = userid; } public string getpassword() { return password; } public void setpassword(string password) { this.password = password; } public string getusergroup() { return usergroup; } public void setusergroup(string usergroup) { this.usergroup = usergroup; } public string getphone() { return phone; } public void setphone(string phone) { this.phone = phone; } public string getemail() { return email; } public void setemail(string email) { this.email = email; } public string getname() { return name; } public void setname(string name) { this.name = name; } }
in getcount must return filtered list count not original list count. see gist more information: https://gist.github.com/fjfish/3024308
i update code:
public class removeuseradapter extends baseadapter implements filterable { private arraylist<usermodel> listcontent; private arraylist<usermodel> searchlist; context context; private filter planetfilter; usermodel content, content1; layoutinflater inflater; public removeuseradapter(context context, arraylist listcontent) { this.context = context; this.listcontent = listcontent; this.searchlist = listcontent; inflater = layoutinflater.from(context); } @override public int getcount() { return searchlist.size(); } @override public object getitem(int i) { return searchlist.get(i); } @override public long getitemid(int i) { return searchlist.get(i).hashcode(); } class viewholder { private textview tvemail, tvuserid; private checkbox checkbox; } @override public view getview(int i, view view, viewgroup viewgroup) { final viewholder viewholder, viewholder1; if (view == null) { layoutinflater inflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service); view = inflater.inflate(r.layout.remove_user_adapter, null); viewholder = new viewholder(); viewholder.tvemail = (textview) view.findviewbyid(r.id.tvemailuser); viewholder.tvuserid = (textview) view.findviewbyid(r.id.tvusergroup); viewholder.checkbox = (checkbox) view.findviewbyid(r.id.checkbox); viewholder.checkbox.setvisibility(view.invisible); view.settag(viewholder); } else { viewholder = (viewholder) view.gettag(); } content = (usermodel) getitem(i); viewholder.tvemail.settext(content.getemail()); viewholder.tvuserid.settext(content.getusergroup()); return view; } public void resetdata() { searchlist=listcontent; } @override public filter getfilter() { filter filter = new filter() { @override protected void publishresults(charsequence charsequence, filterresults result) { searchlist = (arraylist<usermodel>) result.values; notifydatasetchanged(); } @override protected filterresults performfiltering(charsequence constraint) { filterresults results = new filterresults(); arraylist<usermodel> filteredarrlist = new arraylist<usermodel>(); if (constraint == null || constraint.length() == 0) { // set original result return results.count = listcontent.size(); results.values = listcontent; } else { constraint = constraint.tostring().tolowercase(); (int = 0; < listcontent.size(); i++) { content = (usermodel) listcontent.get(i); string data = content.getemail(); string user = content.getuserid(); if (data.tolowercase().startswith(constraint.tostring())) { filteredarrlist.add(content); } } results.count = filteredarrlist.size(); results.values = filteredarrlist; } return results; } }; return filter; }
