Android MVP: handling changes to RecyclerView -


when using recyclerview in android app, many posts , tutorials have adapter handle managing updates list, using solutions diffutil. not seem follow mvp, however, adapter exists in view layer.

so, how can presenter (or model) given responsibility of managing changes list of items displayed recyclerview, while keeping recyclerview date?

for example, recyclerview displaying list of available bluetooth devices phone can connect to, each row containing device name , rssi value. presenter wants display devices greatest least rssi value, , wants insert new devices discovered , remove ones no longer available.

source 1 , source 2 great starters i've used inplement recyclerviews using mvp, not cover data sets actively change.

i think best way use

private observablelist list;

and later

 this.observablelist.addonlistchangedcallback(new observablelist.onlistchangedcallback<observablelist<***>>() {         @override         public void onchanged(observablelist<***> items) {          }          @override         public void onitemrangechanged(observablelist<***> items, int positionstart, int itemcount) {          }          @override         public void onitemrangeinserted(observablelist<***> items, int positionstart, int itemcount) {             recycleradapter.notifydatasetchanged(); //for example             }

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...

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() .
