android - Drop-Down Spinner inside of Pop-Up Window -


how can have drop down spinner inside of popup window? i've tried looking, answers have found create dialog spinner instead (which not want). tried doing custom adapter , seem getting error context (basically, once popup window initiates, context activity gone) how can context pop-up window or how can implement drop down spinner?

edit:

adapter:

public class spinadapter extends arrayadapter<contact>{      // sent context     private context context;     // custom values spinner (user)     private arraylist<contact> values;      public spinadapter(context context, int textviewresourceid,                        arraylist<contact> values) {         super(context, textviewresourceid, values);         this.context = context;         this.values = values;     }      public int getcount(){         return values.size();     }      public contact getitem(int position){         return values.get(position);     }      public long getitemid(int position){         return position;     }       // , "magic" goes here     // "passive" state of spinner     @override     public view getview(int position, view convertview, viewgroup parent) {         // created dynamic textview here, can reference own  custom layout each spinner item         textview label = new textview(context);         label.settextcolor(color.black);         // can current item using values array (users array) , current position         // can reference each method has created in bean object (user class)         label.settext(values.get(position).tostring());          // , return dynamic (or custom) view each spinner item         return label;     }      // , here when "chooser" popped     // same view, can customize if want     @override     public view getdropdownview(int position, view convertview,                                 viewgroup parent) {         textview label = new textview(context);         label.settextcolor(color.black);         label.settext(values.get(position).tostring());          return label;     } }

starting spinner in pop-up window:

private void initiatepopupwindow(){     try{         arraylist<contact> con = tinydb.getlistadd("address", contact.class);         contact = new contact("a","b");         con.add(a);         spinadapter adapt;         adapt = new spinadapter(todoroom.this ,                 android.r.layout.simple_spinner_item,                 con);         layoutinflater inflater = (layoutinflater) todoroom.this                 .getsystemservice(context.layout_inflater_service);          view layout = inflater.inflate(r.layout.addpop,                 (viewgroup) findviewbyid(android.r.id.background));         pw = new popupwindow(layout,300,300,true);         //pw.istouchable();        // pw.isfocusable();         pw.showatlocation(layout, gravity.center, 0,0);          //final edittext address = (edittext)layout.findviewbyid(r.id.editaddress) ;         final spinner address = (spinner) layout.findviewbyid(r.id.spinner);         final edittext name = (edittext)layout.findviewbyid(r.id.editname);          address.setadapter(adapt);           imagebutton = (imagebutton)layout.findviewbyid(r.id.cancelbut);         back.setonclicklistener(                 new view.onclicklistener(){                    public void onclick(view view){                         pw.dismiss();                     }           }         );          button add = (button)layout.findviewbyid(r.id.addbut);         add.setonclicklistener(                 new view.onclicklistener(){                   public void onclick(view view){                       task = new task(name.gettext().tostring(), address.getselecteditem().tostring() );                       todos.add(a);                       tinydb.putlisttask("tasks",(arraylist)todos);                       pw.dismiss();                       list.setadapter(adapter);                    }                 }         );        } catch (exception e){         e.printstacktrace();       } }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
