(using android 2.3.3) error log why sqliteopenhelper.getwritabledatabase() cause exception? surely clever enough realize "oooh db doesn't exist, let's create it! note new sqliteopenhelper(context) worked ok far can tell. however, not know whether oncreate() or onupgrade() triggered. 06-04 18:21:01.706 d/androidruntime( 1280): shutting down vm 06-04 18:21:01.706 w/dalvikvm( 1280): threadid=1: thread exiting uncaught exception (group=0x40015560) 06-04 18:21:01.745 e/androidruntime( 1280): fatal exception: main 06-04 18:21:01.745 e/androidruntime( 1280): java.lang.exceptionininitializererror 06-04 18:21:01.745 e/androidruntime( 1280): @ myapp.com.myactivity.oncreate(myactivity.java:131) 06-04 18:21:01.745 e/androidruntime( 1280): @ android.app.instrumentation.callactivityoncreate(instrumentation.java:1047) 06-04...

let's have integer short sorted arrays , need find intersection equal or more predefined constant. here code , demonstrates want better can explain in words. problem speed. code working slow. takes 15 sec on 2000 elements array(on slow machine). ofcourse can implement own intersection method , parallize code give limited improvement. execution time growing n^2 or , 500k arrays takes very long time. how can rewrite algorithm better perfomance? not limited c# language maybe cpu or gpu has special instructions such job. example: input: 1,3,7,8 2,3,8,10 3,10,11,12,13,14 minsupport = 1 output: 1 , 2: 2, 8 1 , 3: 3 2 , 3: 3, 10 var minsupport = 2; var random = new random(datetime.now.millisecond); // numbers each array unique var sortedarrays = enumerable.range(0,2000) .select(x => enumerable.range(0,30).select(t => random.next(1000)).distinct() .tolist()).tolist(); var result = new list<int[]>(); var resultintersection = new li...

once set contentview layout, how can manage ui via java? also, if start new activity, reset contentview? contentview in 1 activity. assuming in extends activity have do, after setting content view, access views. have button in layout: button homebutton = (button) findviewbyid(r.id.homebutton); homebutton.settext(); homebutton.setonclicklistener() etc if you're in dialog, or need access views in specific circumstances, or you're in intent , need access stuff in main activity's layout: button secondbutton = (button) getactivity().findviewbyid(r.id.secondbutton); //other methods on button edits-- well images, add imageview layout: <imageview android:id="@+id/logoimageview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/logo" android:contentdescription="@string/app_name" android:layout_gravity="center_horizontal"/...

we have system have reason instantiate object before know specific type is. example, wish instantiate class "media" before know whether final class "book" or "cd". here doing. instantiate "media" object, , once know type of media is, instantiate "book", passing in media object. class book extends media { public function __construct( $parent ) { $vars = get_object_vars( $parent ); foreach( $vars $key => $value ) $this->$key = $value; } } //elsewhere $item = new media(); $item->setprice( $price ); //other code, figure out item type $item = new book( $item ); is there better way this? dynamic polymorphism? in case u can't determine type of object can recommend u factory pattern. pattern u has 1 entry point , helps u yr code simpler , readable. short example: class objectfactory { public static function factory($object, $objecttype) { ...
