问题 I have this RelativeView with 3 radiobuttons on top. I want to change the bottom part of the view when the user clicks on one of the buttons. The blue part is the place i want to load different Views in. @Override public void onCheckedChanged(RadioGroup group, int checkedId) { if (checkedId == iVerzekeringen){ layout.removeView(body); // THIS PART IS layout.addView(testview); // NOT WORKING } else if (checkedId == iPersoonlijk){ } else if (checkedId == iNotities){ } } How can i load different

问题 I have two applications, one acting as client and the other as server. In server application I generate ObjectFactory and classes using xjc from Eclipse. As a result, one of this classes is called widgetEvenCall. From the xsd: ... <xs:element name="widgetEventCall"> <xs:complexType> <xs:sequence> <xs:element minOccurs="1" maxOccurs="1" ref="tns:widgetEventDescriptor" /> <xs:element minOccurs="0" maxOccurs="unbounded" ref="tns:widgetParameter" /> </xs:sequence> </xs:complexType> </xs:element>

问题 I am trying to write a simple role playing game in C# to become more familiar with the language. I have a class that loads data from CSV file, creates an object, and places it in a dictionary. Because every aspect of the game has different data (items, actors, skills, etc), I have set up each of these as a class, but this requires me to re-implement a Load() method for each one. After doing this 5 or 6 times, I am wondering if there isn't a better way to implement this. Basically, what I

问题 What's the most "proper" way to pass a dynamically sized array to another function? bool *used = new bool[length](); I've come up with a few ways that compile but I'm not too sure on what the correct way is. E.g. Would these pass by value? static void test(bool arr[]) static void test(bool *arr) Would this one pass by reference? static void test(bool *&arr) Thanks 回答1: Actually, the two first ideas pass the array by address and the third passes the array by reference . You can devise a little

问题 In implementing an interface it seems the common method in tutorials and literature is to declare an ivar and then set the @property then @synthesize . @interface MyClass : NSObject { NSString *myString; } @property (nonatomic, retain) NSString *myString; @end However, omitting the explicit declaration and just putting @property has the same effect. @interface MyClass: NSObject { } @property (nonatomic, retain) NSString *myString; @end So how come most people use @property and an explicit

问题 I am using the following code to convert some Json into a dynamic object. When I use DateTime.Parse on a property of my dynamic type I would expect the var to guess that it's type is a DateTime... instead, it stays as a dynamic. This can't be right, can it? Full example below. var settings = new JavaScriptSerializer().Deserialize<dynamic>(json); var startDate = DateTime.Parse(settings.startDate); var endDate = DateTime.Parse(settings.endDate); var userId = int.Parse(settings.userId);

问题 I'd like to be able to dynamically create an instance method within a class' constructor like so: class Foo{ function __construct() { $code = 'print hi;'; $sayHi = create_function( '', $code); print "$sayHi"; //prints lambda_2 print $sayHi(); // prints 'hi' $this->sayHi = $sayHi; } } $f = new Foo; $f->sayHi(); //Fatal error: Call to undefined method Foo::sayHi() in /export/home/web/private/htdocs/staff/cohenaa/dev-drupal-2/sites/all/modules/devel/devel.module(1086) : eval()'d code on line 12

问题 I'm trying to write a program that dynamically defines ruby classes based on configuration read from a file. I know I can use Class.new to do this. Here's an example program: x = [1,2,3] Test = Class.new do @@mylist = x def foo puts @@mylist end end Test.new.foo When I run this I get the following output (running with ruby 1.9.3p0): c:/utils/test.rb:4: warning: class variable access from toplevel c:/utils/test.rb:7: warning: class variable access from toplevel 1 2 3 Does anyone know what

问题 My brain seems to be in masochistic mode, so after being drowned in this, this and this, it wanted to mess around with some DIY in C#. I came up with the following, which I don't think is the Y-combinator, but it does seem to manage to make a non-recursive function recursive, without referring to itself: Func<Func<dynamic, dynamic>, Func<dynamic, dynamic>> Y = x => x(x); So given these: Func<dynamic, Func<dynamic, dynamic>> fact = self => n => n == 0 ? 1 : n * self(self)(n - 1); Func<dynamic,

问题 Here's how I set my table: self.tableView = [[UITableView alloc] initWithFrame:self.view.bounds]; self.tableView.delegate = self; self.tableView.dataSource = self; self.tableView.estimatedRowHeight = 150; [self.view addSubview:self.tableView]; Within my cells, I call - (CGSize)sizeThatFits:(CGSize)size to programmatically return the height (which is set in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath . I'm not using constraints or
