java - How to keep a users selection even after they close the app? Android -


so @ moment user select colour, shape , time. when app first starts there default each. want happen keep users selection 3 of these after close app while runs in background.

if need me post ask away. thanks.

after writing out problem was, it's not they're not being saved it's fact selections being saved not being displayed properly. i.e border or dropdown menu results it's default value instead of users selection.

so values being saved(my bad) app overwrites these saves , doesn't use border or beings dropdown menu it's default value.

 circularimageview = (circularimageview)findviewbyid(r.id.activity_main_silver_color_button);     circularimageview.setbordercolor(getresources().getcolor(r.color.unselected_border));  circularimageview = (circularimageview)findviewbyid(v.getid());     circularimageview.setbordercolor(getresources().getcolor(r.color.selected_border));

these work independent of each other when border selected, if color selected becomes unselected border. happens if "selected_border" state never saved.

public static void savelockscreenduration(context context, int duration){     getstoredpreferences(context).edit().putint(selected_duration, duration).apply();  public static int getlockscreenduration(context context){     return getstoredpreferences(context)             .getint(selected_duration, default_duration); }

this prefereces stored. default_duration , selected_duration in class called constants.

upon selection can store selected values in shared preferences. , upon launching again can check if values null or not. , display accordingly. read how use shared preferences here.

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() .
