  • How to add Custom View +Relative Layout into ViewGroup

    - by TimothyMiller
    Hi I am creating a View where you can draw on the screen, using a view, where I would like to have a button/titlebar drawn at the top of the screen. Here is my current code public class FingerPaint extends Activity implements ColorPickerDialog.OnColorChangedListener { private Paint mPaint; private MyView mView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LinearLayout main = new LinearLayout(this); mView = new MyView(this); main.addView(this.getLayoutInflater().inflate( R.layout.topbar, null )); main.addView(mView); main.bringChildToFront(mView); setContentView(main); // mView.addView(this.getLayoutInflater().inflate( R.layout.topbar, null )); mPaint = new Paint(); mPaint.setAntiAlias(true); mPaint.setDither(true); mPaint.setColor(0xFFFF0000); mPaint.setStyle(Paint.Style.STROKE); mPaint.setStrokeJoin(Paint.Join.ROUND); mPaint.setStrokeCap(Paint.Cap.ROUND); mPaint.setStrokeWidth(12); mBitmaps=new Bitmap[100]; location=0; actualSize=0; mEmboss = new EmbossMaskFilter(new float[] { 1, 1, 1 }, 0.4f, 6, 3.5f); mBlur = new BlurMaskFilter(8, BlurMaskFilter.Blur.NORMAL); setContentView(main); } public class MyView extends View{ ......... } But when run, only the topbar.xml view is shown. I want the status bar from topbar and the rest down to be from the myView (for drawing on the screen like paint). Am I using ViewGroup properly?

  • Best practices for model driven development using LiveCycle Data Services

    - by Adnan
    What are your advises on using model driven development in developing enterprise applications. Adobe's LiveCycle Data Services looks very promising, I have found numerous tutorials/videos that shows how fast an application can be build by having methods/functions auto-generated. What are the best-practices, is it good/bad to use those auto-generated methods, they can really save a lot of time. All suggestions are welcome, also if you know some existing blog/discussion please let me know.

  • ruby-on-rails: update_attributes overrides model validations?

    - by cbrulak
    I have a typical, Post model: class Post< ActiveRecord::Base validates_presence_of :user_id #Line 1 validates_presence_of :title,:body #Line 2 in the controller, I have: def create if request.post? if login_required @post = Post.new(params[:post]) #Line 3 @post .update_attribute("user_id",session[:userid]) #Line 4 However, if the validations on Line 2 fail the Post will still be created, unless Line 4 is commented out. 1) Why? 2) Suggestions on a fix? Thanks

  • redoing object model construction to fit with asynchronous data fetching

    - by Andrew Patterson
    I have a modeled a set of objects that correspond with some real world concepts. TradeDrug, GenericDrug, TradePackage, DrugForm Underlying the simple object model I am trying to provide is a complex medical terminology that uses numeric codes to represent relationships and concepts, all accessible via a REST service - I am trying to hide away some of that complexity with an object wrapper. To give a concrete example I can call TradeDrug d = Searcher.FindTradeDrug("Zoloft") or TradeDrug d = new TradeDrug(34) where 34 might be the code for Zoloft. This will consult a remote server to find out some details about Zoloft. I might then call GenericDrug generic = d.EquivalentGeneric() System.Out.WriteLine(generic.ActiveIngredient().Name) in order to get back the generic drug sertraline as an object (again via a background REST call to the remote server that has all these drug details), and then perhaps find its ingredient. This model works fine and is being used in some applications that involve data processing. Recently however I wanted to do a silverlight application that used and displayed these objects. The silverlight environment only allows asynchronous REST/web service calls. I have no problems with how to make the asychhronous calls - but I am having trouble with what the design should be for my object construction. Currently the constructors for my objects do some REST calls sychronously. public TradeDrug(int code) { form = restclient.FetchForm(code) name = restclient.FetchName(code) etc.. } If I have to use async 'events' or 'actions' in order to use the Silverlight web client (I know silverlight can be forced to be a synchronous client but I am interested in asychronous approaches), does anyone have an guidance or best practice for how to structure my objects. I can pass in an action callback to the constructor public TradeDrug(int code, Action<TradeDrug> constructCompleted) { } but this then allows the user to have a TradeDrug object instance before what I want to construct is actually finished. It also doesn't support an 'event' async pattern because the object doesn't exist to add the event to until it is constructed. Extending that approach might be a factory object that itself has an asynchronous interface to objects factory.GetTradeDrugAsync(code, completedaction) or with a GetTradeDrugCompleted event? Does anyone have any recommendations?

  • Calling a method in a view controller from a view

    - by Lakshmie
    I have to invoke a method present in a view controller who's reference is available in the view. When I try to call the method like any other method, for some reason, iPhone just ignores the call. Can somebody explain as to why this happens and also how can I go about invoking this method? In the view I have this method: -(void) touchesBegan :(NSSet *) touches withEvent:(UIEvent *)event{ NSArray* mySubViews = [self subviews]; for (UITouch *touch in touches) { int i = 0; for(; i<[mySubViews count]; i++){ if(CGRectContainsPoint([[mySubViews objectAtIndex:i] frame], [touch locationInView:self])){ break; } } if(i<[mySubViews count]){ // viewController is the reference to the View Controller. [viewController pointToSummary:[touch locationInView:self].y]; NSLog(@"Helloooooo"); break; } } } Whenever the touches event is triggered, Hellooooo gets printed in the console but the method before that is simply ignored

  • UINavigationBar unresponsive after canceling a UITableView search in nav controller in tab bar in a popover

    - by Mark
    Ok, this is an odd one and I can reproduce it with a new project easily. Here is the setup: I have a UISplitViewController. In the left side I have a UITabBarController. In this tab bar controller I have two UINavigationControllers. In the navigation controllers I have UITableViewControllers. These table views have search bars on them. Ok, what happens with this setup is that if I'm in portrait mode and bring up this view in the popover and I start a search in one of the table views and cancel it, the navigation bar becomes unresponsive. That is, the "back" button as well as the right side button cannot be clicked. If I do the exact same thing in landscape mode so we are not in a popover, this doesn't happen. The navigation bar stays responsive. So, the problem only seems to happen inside a popover. I've also noticed that if I do the search but click on an item in the search results which ends up loading something into the "detail view" of the split view and dismissing the popover, and then come back to the popover and then click the Cancel button for the search, the navigation bar is responsive. My application is a universal app and uses the same tab bar controller in the iPhone interface and it works there without this issue. As I mentioned above, I can easily reproduce this with a new project. Here are the steps if you want to try it out yourself: start new project - split view create new UITableViewController class (i named TableViewController) uncomment out the viewDidLoad method as well as the rightBarButtonItem line in viewDidLoad (so we will have an Edit button in the navigation bar) enter any values you want to return from numberOfSectioinsInTableView and numberOfRowsInSection methods open MainWindow.xib and do the following: please note that you will need to be viewing the xib in the middle "view mode" so you can expand the contents of the items drag a Tab Bar Controller into the xib to replace the Navigation Controller item drag a Navigation Controller into the xib as another item under the Tab Bar Controller delete the other two view controllers that are under the Tab Bar Controller (so, now our tab bar has just the one navigation controller on it) inside the navigation controller, drag in a Table View Controller and use it to replace the View Controller (Root View Controller) change the class of the new Table View Controller to the class created above (TableViewController for me) double-click on the Table View under the new Table View Controller to open it up (will be displayed in the tab bar inside the split view controller) drag a "Search Bar and Search Display" onto the table view save the xib run the project in simulator while in portrait mode, click on the Root List button to bring up popover notice the Edit button is clickable click in the Search box - we go into search mode click the Cancel button to exit search mode notice the Edit button no longer works So, can anyone help me figure out why this is happening? Thanks, Mark

  • Bind postback data from a strong type view of type List<T>

    - by Robert Koritnik
    I have a strong type view of type List<List<MyViewModelClass>> The outer list will always have two lists of List<MyViewModelClass>. For each of the two outer lists I want to display a group of checkboxes. Each set can have an arbitrary number of choices. My view model class looks similar to this: public class MyViewModelClass { public Area Area { get; set; } public bool IsGeneric { get; set; } public string Code { get; set; } public bool IsChecked { get; set; } } So the final view will look something like: Please select those that apply: First set of choices: x Option 1 x Option 2 x Option 3 etc. Second set of choices: x Second Option 1 x Second Option 2 x Second Option 3 x Second Option 4 etc. Checkboxes should display MyViewModelClass.Area.Name, and their value should be related to MyViewModelClass.Area.Id. Checked state is of course related to MyViewModel.IsChecked. Question I wonder how should I use Html.CheckBox() or Html.CheckBoxFor() helper to display my checkboxes? I have to get these values back to the server on a postback of course. I would like to have my controller action like one of these: public ActionResult ConsumeSelections(List<List<MyViewModelClass>> data) { // process data } public ActionResult ConsumeSelections(List<MyViewModelClass> first, List<MyViewModelClass> second) { // process data } If it makes things simpler, I could make a separate view model type like: public class Options { public List First { get; set; } public List Second { get; set; } } As well as changing my first version of controller action to: public ActionResult ConsumeSelections(Options data) { // process data }

  • iPhone modal view inside another modal view?

    - by Rick
    My App uses a modal view when users add a new foo. The user selects a foo type using this modal view. Depending on what type is selected, the user needs to be asked for more information. I'd like to use another modal view to ask for this extra information. I've tried to create the new modal view like the first one (which works great) and it leads to stack overflow/“Loading Stack Frames” error in Xcode. Am I going about this in completely the wrong way i.e. is this just a really bad idea? Should I rethink the UI itself? UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addController]; [self presentModalViewController:navigationController animated:YES];

  • Is this part of MVC in .NET?

    - by 4thSpace
    I have a .NET MVC winform app. I've created an AppDelegate class that handles application startup and shutdown...for now (it might do more later). Winform apps have a Program.cs file that does some app initialization, starts the message pump and creates the first form. In my app, the first form is AppDelegate, which isn't really a form but is forced that way by Application.Run(). AppDelegate does any further app initialization and starts the first Controller, which then initializes any child controllers (these then create their views). I don't consider events occuring in Program.cs and AppDelegate as part of the MVC. Conceptually, what would these be called?

  • How to draw some lines in a view element defined in the xml layout

    - by Nils
    Hello, I have problems drawing some simple lines in a view object (Android programming). First I created the layout with the view element(kind of painting area) in it (XML file). [...] < View android:id="@+id/viewmap" android:layout_width="572px" android:layout_height="359px" android:layout_x="26px" android:layout_y="27px" [...] ... and tried then to access it to draw some lines. Unfortunately the program is running and other UI elements like buttons are displayed, but I can't see the drawings. What's wrong ? [...] viewmap = (View) findViewById(R.id.viewmap); Canvas canvas = new Canvas(); viewmap.draw(canvas); Paint p = new Paint(); p.setColor(Color.BLUE); p.setStyle(Paint.Style.STROKE); canvas.drawColor(Color.WHITE); p.setColor(Color.BLUE); canvas.drawLine(4, 4, 29, 5, p); p.setColor(Color.RED); viewmap.draw(canvas); [...] Thanks for help :) !

  • Animating translation and scaling of view in Android

    - by hgpc
    I have to animate a view from state A to B with changes to its scale, position and scrolling. I know everything about state A (widthA, heightA, topA, leftA, scrollXA, scrollYA) and state B (widthB, heightB, topB, leftB, scrollXB, scrollYB). So far I wrote the following code: AnimationSet animation = new AnimationSet(true); int toXDelta; // What goes here? int toYDelta; // What goes here? TranslateAnimation translateAnimation = new TranslateAnimation(1, toXDelta, 1, toYDelta); translateAnimation.setDuration(duration); animation.addAnimation(translateAnimation); float scale = (float) widthB / (float) widthA; ScaleAnimation scaleAnimation = new ScaleAnimation(1, scale, 1, scale); scaleAnimation.setDuration(duration); animation.addAnimation(scaleAnimation); animation.setAnimationListener(new AnimationListener() { @Override public void onAnimationEnd(Animation arg0) { view.clearAnimation(); // Change view to state B } @Override public void onAnimationRepeat(Animation arg0) {} @Override public void onAnimationStart(Animation arg0) {} }); view.startAnimation(animation); Is this the right way to do this? If so, how should I calculate the values of toXDelta and toYDelta? I'm having trouble finding the exact formula. Thanks!

  • iphone sdk: Table view not working in the first 5 tabs but in the more view

    - by LHT
    Hi, I only started with sdk but this problem is bugging me now for a view days: I created a UITableView and added it to my Tabs. When this TableView is in the first 4 Tabs and u go look at it, it only shows the items on the table but when clicking on them nothing happens (it doesn't go to the next view). BUT when i put this same tab behind the 5th so it goes in the automatic MORE view everything works fine. I'm assuming this is because this more view is implementing some kind of table class. But i can't figure it out. I compared all the files with a working example but it seems to be all the same. ah ya my current project is a window based application. Though i copied most of the code from a navigation based application. Any ideas?

  • Create a view like Tweetie's User Profile view

    - by Graeme
    Hi, I'm just wondering if anyone has any idea on how you can create a view that looks like the user profile view in apps like Tweetie, where there are seemingly multiple tables with a couple of normal (straight up and down tables) and then two rows of six cells, which in Tweeties case have the number of followers, following etc. I'm trying to make a similar view for my app, but can't seem to find out the best way to create it. Any tutorials, advice etc. would be appreciated. Thanks. P.S. Here's a picture of the view which I'm trying to recreate.

  • changing a picker to table view OR having multiple table views on the same view

    - by Brodie4598
    Hello - My iPad app was rejected due to my use of a picker. The picker was used to control a table view. In my view, a picker was displaying a series of items and when one of those items was selected, it used that selection to populate a table with data. (hopefully that makes sense). Now I need to do this without the picker so I need to have the data that was in the picker be represented in a table view. My question, is how do I have multiple tableViews in the same view? I'm guessing I need to have some kind of if statement in the tableview delegate methods, but I'm not quite sure what the if statement needs to be. Or maybe i'm thinking of this the totally wrong way thanks

  • How do I call the methods in a model via controller? Zend Framework

    - by Joel
    Hi guys, I've been searching for tutorials to better understand this, but I'm having no luck. Please forgive the lengthy explination, but I want make sure I explain myself well. First, I'm quite new to the MVC structure, though I have been doing tutorials and learning as best I can. I have been moving over a live site into the Zend Framework model. So far, I have all the views within views/scripts/index/example.phtml. So therefore I'm using one IndexController and I have the code in each Action method for each page: IE public function exampleAction() Because I didn't know how to interact with a model, I put all the methods at the bottom of the controller (a fat controller). So basically, I had a working site by using a View and Controller and no model. ... Now I'm trying to learn how to incorporate the Model. So I created a View at: view/scripts/calendar/index.phtml I created a new Controller at: controller/CalendarControllers.php and a new model at: model/Calendar.php The problem is I think I'm not correctly communication with the model (I'm still new to OOP). Can you look over my controller and model and tell me if you see a problem. I'm needing to return an array from runCalendarScript(), but I'm not sure if I can return an array into the object like I'm trying to? I don't really understand how to "run" the runCalendarScript() from the controller? Thanks for any help! I'm stripping out most of the guts of the methods for the sake of brevity: controller: <?php class CalendarController extends Zend_Controller_Action { public function indexAction() { $finishedFeedArray = new Application_Model_Calendar(); $this->view->googleArray = $finishedFeedArray; } } model: <?php class Application_Model_Calendar { public function _runCalendarScript(){ $gcal = $this->_validateCalendarConnection(); $uncleanedFeedArray = $this->_getCalendarFeed($gcal); $finishedFeedArray = $this->_cleanFeed($uncleanedFeedArray); return $finishedFeedArray; } //Validate Google Calendar connection public function _validateCalendarConnection() { ... return $gcal; } //extracts googles calendar object into the $feed object public function _getCalendarFeed($gcal) { ... return $feed; } //cleans the feed to just text, etc protected function _cleanFeed($uncleanedFeedArray) { $contentText = $this->_cleanupText($event); $eventData = $this->_filterEventDetails($contentText); return $cleanedArray; } //Cleans up all formatting of text from Calendar feed public function _cleanupText($event) { ... return $contentText; } //filterEventDetails protected function _filterEventDetails($contentText) { ... return $data; } }
