android - Change list item background in custom adapter -

-

i have custom adapter , want pick out new messages. adapter looks like. new messages have new_message icon.

public class inputmessagesadapter extends baseadapter { private context context; private layoutinflater layoutinflater; private list<message> messagelist; private list<sellerstatement> sellerstatementlist; private list<integer> messagesids; private string arrayname = "messagesids"; private sharedpreferences prefs;      public inputmessagesadapter(context context, list<message> messagelist, list<sellerstatement> sellerstatementlist) {         this.context = context;         layoutinflater = (layoutinflater) this.context.getsystemservice(context.layout_inflater_service);         this.messagelist = messagelist;         this.sellerstatementlist = sellerstatementlist;         prefs = preferencemanager.getdefaultsharedpreferences(context);          int size = prefs.getint(arrayname + "_size", 0);         integer[] temparray = new integer[size];          for(int = 0; < size; i++)             temparray[i] = prefs.getint(arrayname + "_" + i, -1);          messagesids = new arraylist<integer>(arrays.aslist(temparray));     }      @override         public int getcount() {         return messagelist.size();     }      @override     public object getitem(int position) {         return messagelist.get(position);     }      @override     public long getitemid(int position) {         return 0;     }      @override     public view getview(final int position, view convertview, final viewgroup parent) {         message message = messagelist.get(position);          view view = convertview;         if (view == null) {             view = layoutinflater.inflate(r.layout.fragment_messages_new_row, null);         }          textview subject = (textview) view.findviewbyid(r.id.tvsubject);         textview date = (textview) view.findviewbyid(r.id.tvdate);         textview sender = (textview) view.findviewbyid(r.id.tvsender);         imageview icon = (imageview) view.findviewbyid(r.id.immessage);           sellerstatement sellerstatement = sellerstatementlist.get(position);          subject.settext(message.getsubject());         simpledateformat sdf = new simpledateformat("yyyy-mm-dd");         date.settext(string.valueof(sdf.format(message.gettimestamp())));         sender.settext(sellerstatement.getsender().getgoogleaccount());          drawable image = context.getresources().getdrawable(r.drawable.old_message);          if(!messagesids.contains(message.getmessageid()))             image = context.getresources().getdrawable(r.drawable.new_message);           icon.setimagedrawable(image);          return view;     } }

i try it, items change color.

if(!messagesids.contains(message.getmessageid())) {     image = context.getresources().getdrawable(r.drawable.new_message);     view.setbackgroundcolor(color); }

and work incorrect (i change background color layout)

view view = convertview; if (view == null) {     if(!messagesids.contains(message.getmessageid())) {         view = layoutinflater.inflate(r.layout.fragment_messages_new_row, null);     } else {             view = layoutinflater.inflate(r.layout.fragment_messages_row, null);     } }

how can solve task?

it simple:

 view view = convertview; //find line in code  view.setbackgroundcolor(color.cyan); //add line below

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
