android - Onclick with Fragment , there's no error but it doesn't work - 


public class frag2 extends fragment {      button btn_service;      @override      public view oncreateview(layoutinflater inflater, viewgroup container,                              bundle savedinstancestate) {          view = inflater.inflate(r.layout.fragment2, container, false);         ((edittext) good.findviewbyid(r.id.edittext)).settext("edit text test");           final view v = inflater.inflate(r.layout.fragment2, container,                 false);          btn_service = (button) v.findviewbyid(r.id.btn);         btn_service.setonclicklistener(new view.onclicklistener() {              @override             public void onclick(view view) {                 snackbar.make(view, "test snackbar button", snackbar.length_long)                         .setaction("action", null).show();             }          });         return good;     }

i want know how code onclick fragment layout. i'm novice in android coding. may ask wrong question.

you creating 2 separate views good , v need good , v there , doing nothing because good the actual fragment view displayed in activity (due return good) need bind action child of good

from inflate (int resource, viewgroup root, boolean attachtoroot)

inflate new view hierarchy specified xml resource.

//final view v = inflater.inflate(r.layout.fragment2, container, //        false);  btn_service = (button) good.findviewbyid(r.id.btn); //                     ^^^^

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() .
