  • A outsiders view of Fusion Apps.

    - by Grant Ronald
    Over the last couple of years I've heard some people comment that "Fusion isn't real".  I've heard customers say they wanted to choose different technology stacks because they felt that Fusion "wouldn't work for them". Interesting to hear an outsiders view of Fusion Apps. To one particular customer who asked me "do you think I've painted myself into a corner by choosing ..." (and I'll not name the product he mentioned) - Yes, I do think you are in a corner now ;o)

  • Dynamically Create Different Controls on Grid view as a Single Column

    Usually we use Grid view control to display either a static or dynamic data (ie., in row column format). We may use either datatable , dataview , dataset to display records. Here is also the same but quit different to create more than one control in gridview as a single column. We may add such a set of controls for more than one time depends on the need of the user. Here is the code for you dear friends....

  • view switcher in window

    - by RhZ
    I used to have button in my file viewer window that allowed me to easily change from list to compact to icons, which was really convenient. Now, in 12.04 (running gnome fallback mode to mostly keep my original layout) I don't have that anymore, I have to go to 'view' and then at the bottom of the menu choose the way I want to display the files. Any way to get this switcher back? In its place I just have a search function and buttons that I don't need and never use.

    - by praveenb
    Hi, im new to Android programing I build a listview showing station names, that grabs its data from a URL. I used ArrayAdapter to accomplish listview with data. I need to navigate through station names in listview, using previous, next buttons click. I google for this task and tried in different ways to workout bt im not able to solve. shall any one pls help me out for this issue. Thanks in advance...... I tried like this ` private ListView stationList; . . public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.playscreen); // move up event handler preButton= (ImageButton) findViewById(R.id.prevButton); preButton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { movePre(); } }); // move down event handler nxtButton= (ImageButton) findViewById(R.id.nextButton); nxtButton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { moveNxt(); } }); stationList.setAdapter(new StationAdapter(this, android.R.layout.simple_list_item_1, _stationList)); } else { Log.d(TAG, "No Stations"); } } private void movePre(){ stationList.setSelection(stationList.getSelectedItemPosition() + 1); } // Move selected item "down" in the ViewList. private void moveNxt(){ stationList.setSelection(stationList.getSelectedItemPosition() + 1); } private class StationAdapter extends ArrayAdapter { private Vector<Station> items; public StationAdapter(Context context, int textViewResourceId, Vector<Station> items) { super(context, textViewResourceId, items); this.items = items; } public void setSelectedPosition(int pos){ selectedPos = pos; // inform the view of this change notifyDataSetChanged(); } public int getSelectedPosition(){ return selectedPos; } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.row, null); } Station st = items.get(position); if (st != null) { TextView tt = (TextView) v.findViewById(R.id.toptext); TextView bt = (TextView) v.findViewById(R.id.bottomtext); if (tt != null) { tt.setText(st.getStationName()); } if (bt != null) { bt.setText(st.getCT()); } } return v; } } `

  • TableView frame not resizing properly when pushing a new view controller and the keyboard is hiding

    - by Pete
    Hi, I must be missing something fundamental here. I have a UITableView inside of a NavigationViewController. When a table row is selected in the UITableView (using tableView:didSelectRowAtIndexPath:) I call pushViewController to display a different view controller. The new view controller appears correctly, but when I pop that view controller and return the UITableView is resized as if the keyboard was being displayed. I need to find a way to have the keyboard hide before I push the view controller so that the frame is restored correctly. If I comment out the code to push the view controller then the keyboard hides correctly and the frame resizes correctly. The code I use to show the keyboard is as follows: - (void) keyboardDidShowNotification:(NSNotification *)inNotification { NSLog(@"Keyboard Show"); if (keyboardVisible) return; // We now resize the view accordingly to accomodate the keyboard being visible keyboardVisible = YES; CGRect bounds = [[[inNotification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue]; bounds = [self.view convertRect:bounds fromView:nil]; CGRect tableFrame = tableViewNewEntry.frame; tableFrame.size.height -= bounds.size.height; // subtract the keyboard height if (self.tabBarController != nil) { tableFrame.size.height += 48; // add the tab bar height } [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(shrinkDidEnd:finished:contextInfo:)]; tableViewNewEntry.frame = tableFrame; [UIView commitAnimations]; } The keyboard is hidden using: - (void) keyboardWillHideNotification:(NSNotification *)inNotification { if (!keyboardVisible) return; NSLog(@"Keyboard Hide"); keyboardVisible = FALSE; CGRect bounds = [[[inNotification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue]; bounds = [self.view convertRect:bounds fromView:nil]; CGRect tableFrame = tableViewNewEntry.frame; tableFrame.size.height += bounds.size.height; // add the keyboard height if (self.tabBarController != nil) { tableFrame.size.height -= 48; // subtract the tab bar height } tableViewNewEntry.frame = tableFrame; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(_shrinkDidEnd:finished:contextInfo:)]; tableViewNewEntry.frame = tableFrame; [UIView commitAnimations]; [tableViewNewEntry scrollToNearestSelectedRowAtScrollPosition:UITableViewScrollPositionMiddle animated:YES]; NSLog(@"Keyboard Hide Finished"); } I trigger the keyboard being hidden by resigning first responser for any control that is the first responder in ViewWillDisappear. I have added NSLog statements and see things happening in the log file as follows: Show Keyboard ViewWillDisappear: Hiding Keyboard Hide Keyboard Keyboard Hide Finished PushViewController (an NSLog entry at the point I push the new view controller) From this trace, I can see things happening in the right order, but It seems like when the view controller is pushed that the keyboard hide code does not execute properly. Any ideas would be really appreciated. I have been banging my head against the keyboard for a while trying to find out what I am doing wrong.

  • Eclipse Juno: Can't find fast view panel

    - by otakun85
    Version: Eclipse 4.2 Codename: Juno I don't see a fast view bar in eclipse 4.2. I can't rightclick on a view and enable fast view. The fast view options under General - Perspectives does nothing. Was the fast view feature removed or am I missing something? I've looked up at http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.platform.doc.user%2Ftasks%2Ftasks-9b.htm , but that didn't helped either.

  • Loading Accessory callout view for mkannotationview

    - by Zap
    I have a map annotation view that contains a rightcallout button which loads an accessory view which is a UIViewController class. I am using resuable annotations, but am wondering how I can pass updated information to my UIViewController class. Let's say I have 2 string values which map to 2 UILabels on my view. How can I update those values after the initial accessory view has already been loaded into memory as a resusable view? Any help would be appreciated.

  • Gap appears between navigation bar and view after rotating & tab switching

    - by Bogatyr
    My iphone application is showing strange behavior when rotating: a gap appears between the navigation title and content view inside a tab bar view (details on how to reproduce are below). I've created a tiny test case that exhibits the same problem: a custom root UIViewController, which creates and displays a UITabBarController programmatically, which has two tabs: 1) plain UIViewController, and 2) UINavigationController created programmatically with a single plain UIViewController content view. The complete code for the application is in the root controller's viewDidLoad (every "*VC" class is a totally vanilla UIViewController subclass with XIB for user interface from XCode, with only the view background color changed to clearly identify each view, nothing else). Here's the viewDidLoad code, and the shouldAutorotateToInterfaceOrientation code, this code is the entire application basically: - (void)viewDidLoad { [super viewDidLoad]; FirstVC *fvc = [[FirstVC alloc] initWithNibName:@"FirstVC" bundle:nil]; NavContentsVC *ncvc = [[NavContentsVC alloc] initWithNibName:@"NavContentsVC" bundle:nil]; UINavigationController *svc = [[UINavigationController alloc] initWithRootViewController:ncvc]; NSMutableArray *localControllersArray = [[NSMutableArray alloc] initWithCapacity:2]; [localControllersArray addObject:fvc]; [localControllersArray addObject:svc]; fvc.title = @"FirstVC-Title"; ncvc.title = @"NavContents-Title"; UITabBarController *tbc = [[UITabBarController alloc] init]; tbc.view.frame = CGRectMake(0, 0, 320, 460); [tbc setViewControllers:localControllersArray]; [self.view addSubview:tbc.view]; [localControllersArray release]; [ncvc release]; [svc release]; [fvc release]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } Here's how to reproduce the problem: 1) start application 2) rotate device (happens in simulator, too) to landscape (UITabBar properly rotates) 3) click on tab 2 4) rotate device to portrait -- notice gap of root view controller's background color of about 10 pixels high beneath the Navigation title bar and the Navigation content view. 5) click tab 1 6) click tab 2 And the gap is gone! From my real application, I see that the gap remains during all VC push and pops while the NavigationController tab is active. Switching away to a different tab and back to the Nav tab clears up the gap. What am I doing wrong? I'm running on SDK 3.1.3, this happens both on the simulator and on the device. Except for this particular sequence, everything seems to work fine. Help!

  • Table View Controller Problems

    - by happyCoding25
    Hello, I added a table view into a view in interface builder and now I need to wire it up to some pre-made classes that you can generate in xcode. I set the tableview controller's class to the class in xcode and wired the dataSource and delegate to my table view but the app just crashes. Im not sure how to get data to properly load into my table view when using a tableview in a different view. If anyone knows how to do this any help is appreciated. Thanks

  • Passing Info From One View to Another

    - by 01010011
    EDIT 1. The results of a query from my database are displayed on my view page. Next to each unique result is a button: // first_view.php <?php echo form_open('controller/method'); ?> <?php foreach($results_found as $item): ?> <p><?php echo $item->name ?></p> <p><?php form_submit('buy','Buy This'); ?></p> When a user clicks on one of these buttons (lets say button 4), I would like to display the user's choice from the array onto another view. I've tried using this: // first_view.php <?php echo $this->session->set_userdata('choice',$item); ?> immediately before // first_view.php <?php echo form_close(); ?> thinking that the user's final choice would be stored there so I can display it on another view like this: // second_controller.php $c = $this->session->userdata('choice'); // second_view.php echo 'Your Choose: '. $c; However, what actually displays is the last result displayed on first_view.php, not what the user choose. My question is, if the user clicked on button 4, how do I get that particular choice displayed onto another view? END OF EDIT1 ORIGINAL QUESTION My view page (CodeIgniter) displays the contents of an array in the form of several links. If a user clicks on a link, I want the user to be taken to another view page (via a controller) that gives more information concerning that particular link (which is stored in that particular position in the array) My question is, how do I access and display the contents of that particular location within the array on the second view file without getting a "Undefined variable error" on the second view? Here is what I am trying to do in code form // my_controller.php $array_name['variable_name']; $this->load->view('first_view.php'); // first_view.php <?php foreach($variable_name as $vn): ?> <?php echo anchor('controller_name' $vn->info ?> // if user clicks on 3rd link <?php endforeach ?> // I want to beable to access // index 2 of the array in the // second view file so I can // display more info // second_view.php <?php $vn[2]->info ?>

  • UINavigation Bar while moving view for writing in a textfield

    - by ObiWanKeNerd
    i'm using this code to move the view when i'm about to type on a textfield, otherwise the keyboard may cover the textfield if it's in the lower side of the screen. I would like to know if there is a way to maintain the UINavigation Bar in it's place, because with this code the bar will move with all the view outside the screen, becoming untouchable until i end editing the textfield (closing the keyboard). CGFloat animatedDistance; static const CGFloat KEYBOARD_ANIMATION_DURATION = 0.3; static const CGFloat MINIMUM_SCROLL_FRACTION = 0.2; static const CGFloat MAXIMUM_SCROLL_FRACTION = 0.8; static const CGFloat PORTRAIT_KEYBOARD_HEIGHT = 216; static const CGFloat LANDSCAPE_KEYBOARD_HEIGHT = 162; - (void)textFieldDidBeginEditing:(UITextField *)textField { CGRect textFieldRect = [self.view.window convertRect:textField.bounds fromView:textField]; CGRect viewRect = [self.view.window convertRect:self.view.bounds fromView:self.view]; CGFloat midline = textFieldRect.origin.y + 0.5 * textFieldRect.size.height; CGFloat numerator = midline - viewRect.origin.y - MINIMUM_SCROLL_FRACTION * viewRect.size.height; CGFloat denominator = (MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION) * viewRect.size.height; CGFloat heightFraction = numerator / denominator; if (heightFraction < 0.0) { heightFraction = 0.0; } else if (heightFraction > 1.0) { heightFraction = 1.0; } UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation]; if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) { animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction); } else { animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction); } CGRect viewFrame = self.view.frame; viewFrame.origin.y -= animatedDistance; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION]; [self.view setFrame:viewFrame]; [UIView commitAnimations]; } - (void)textFieldDidEndEditing:(UITextField *)textField { CGRect viewFrame = self.view.frame; viewFrame.origin.y += animatedDistance; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION]; [self.view setFrame:viewFrame]; [UIView commitAnimations]; } Thanks in advance!

  • Change TabBarController in detail view

    - by Antriel
    So I have a TabBarController with 2 views. One of the views is a TableView in navigationController. When user selects a row I push a detail view there. I want this detail view to have its own TabBarController different from the former one. So basically the question is if I can push a view on top different view with different TabBarController, but using navigationController not as a modal view.

Basically what I want to know if that the view for a given action has rendered without errors I m already testing the view model but I want to see that rendering the view giving a correct ViewData.Model works

  • ListAdapter --> How apply convert view changes to specific view item only?

    - by user1847544
    I am trying to get have the lower part of list view slide down, by hiding an unhiding linear layout in list_item. The problem is the view seems to get reused in LayoutAdapter so that the change does not just effect the view I intended to apply it to. Instead it shows up wherever the view is reused. How can I restrict the drop down to just the view on which I requested the dropdown? By drop down I mean unhide the linear layout.

  • iPad After drill down in Split View's Master View, Detail View will not load.

    - by Stuart
    Hi, completely new to coding other than html. I have an iPad app based on the MultiDetailsView/SplitView sample in Xcode. I have a master view that drills down and loads new detail views, both at the same time when needed. But when I do drill down the lower views will not load their new detail views. If I change the master 'RootViewController' in the Main nib to any of my other navigation views they will load their correct detail views. I think it could be that my lower views are somehow not connected to the SplitViewController. I have tried many things but I am just guessing. Any help with this would be great, thanks!

  • asp.net MVC should a View-Model Encapsulate Domain-Model?

    - by Myster
    Hi all I've see a lot of MVC examples where domain-objects are passed directly to views, this will work fine if your view is simple. The common alternative is to have a view-model which has all the same properties as your domain-model + any extra properties your view may need (such as 'confirmPassword'). Before doing too much reading and before discovering AutoMapper I started creating my own variant of view-model where the domain-object (or multiple domain objects) are simply properties of the view-model. Have I done a bad thing? What problems or benefits could be derived from this approach? Under what circumstances might this way of doing things work well?

  • Entity Framework - Merging 2 physical tables into one "virtual" table problems...

    - by Keith Barrows
    I have been reading up on porting ASP.NET Membership Provider into .NET 3.5 using LINQ & Entities. However, the DB model that every single sample shows is the newer model while I've inherited a rather old model. Differences: The User Table is split into a pair of User & Membership Tables. All of the tables in the DB are prepended with aspnet_ I have Lowered versions of some columns (UserName, Email, etc) To work with this I have copied the properties from the Membership table into the User table (in the DB this is a 1<-1 relationship, not a 1<-0,1), renamed aspnet_Applications to Application, aspnet_Profiles to Profile, aspnet_Users to User and aspnet_Roles to Role. (See image) Link to full size image of model Now, I am running into one of 2 problems when I try to compile. Using the model in the image I get this error: Problem in Mapping Fragment starting at line 464: EntitySets 'UserSet' and 'aspnet_Membership' are both mapped to table 'aspnet_Membership'. Their Primary Keys may collide. If I delete the aspnet_Membership table from my model (to handle the above error) I then get: Problem in Mapping Fragment starting at line 384: Column aspnet_Membership.ApplicationId in table aspnet_Membership must be mapped: It has no default value and is not nullable. My ability to hand edit the backing stores is not the best and I don't want to just hack something in that may break other things. I am looking for suggestions, best practices, etc to handle this. Note: Moving the data tables themselves is not an option as I cannot replace all the logic in the existing apps. I am building this EF Provider for a new App. Over the next 6 months the old app(s) will migrate bit-by-bit to the new structures. Note: I added a link just under the image to the full size image for better viewing.

  • Django: How to dynamically add tag field to third party apps without touching app's source code

    - by Chris Lawlor
    Scenario: large project with many third party apps. Want to add tagging to those apps without having to modify the apps' source. My first thought was to first specify a list of models in settings.py (like ['appname.modelname',], and call django-tagging's register function on each of them. The register function adds a TagField and a custom manager to the specified model. The problem with that approach is that the function needs to run BEFORE the DB schema is generated. I tried running the register function directly in settings.py, but I need django.db.models.get_model to get the actual model reference from only a string, and I can't seem to import that from settings.py - no matter what I try I get an ImportError. The tagging.register function imports OK however. So I changed tactics and wrote a custom management command in an otherwise empty app. The problem there is that the only signal which hooks into syncdb is post_syncdb which is useless to me since it fires after the DB schema has been generated. The only other approach I can think of at the moment is to generate and run a 'south' like database schema migration. This seems more like a hack than a solution. This seems like it should be a pretty common need, but I haven't been able to find a clean solution. So my question is: Is it possible to dynamically add fields to a model BEFORE the schema is generated, but more specifically, is it possible to add tagging to a third party model without editing it's source. To clarify, I know it is possible to create and store Tags without having a TagField on the model, but there is a major flaw in that approach in that it is difficult to simultaneously create and tag a new model.

  • when to clear or make null asp .net mvc models?

    - by SARAVAN
    HI, I am working in an asp .net mvc application. I am using the model and storing some of the values which i need to preserve between the page posts, in the form of datacontexts. Say my model looks something like this: public SelectedUser SelectedUserDetails { //get and set has //this.datacontext.data.SelectedUser = ..... //return this.datacontext.data..... } Now when this model needs to be cleared? I have many such models with many properties and datacontext. But I don't have an idea on when to clear it. Is there a way or an event that can be triggered automatically when the model is not used for a long time? Oneway I thought is when i navigate away from a page which uses my underlying model, I can clear that model if its no longer used anywhere and initialise it back as needed. But I need to clear almost many models at many points. Is there an automatic way that can clear models when it is no longer used beacuse care can be taken by my code to initialise them when I need them, but I don't know when to clear them when I no longer need them. I need this to get rid of any memory related issues. Any thoughts or comments?

  • How to create projection/view matrix for hole in the monitor effect

    - by Mr Bell
    Lets say I have my XNA app window that is sized at 640 x 480 pixels. Now lets say I have a cube model with its poly's facing in to make a room. This cube is sized 640 units wide by 480 units high by 480 units deep. Lets say the camera is somewhere in front of the box looking at it. How can I set up the view and projection matrices such that the front edge of the box lines up exactly with the edges of the application window? It seems like this should probably involve the Matrix.CreatePerspectiveOffCenter method, but I don't fully understand how the parameters translate on to the screen. For reference, the end result will be something like Johhny Lee's wii head tracking demo: http://www.youtube.com/watch?v=Jd3-eiid-Uw&feature=player_embedded P.S. I realize that his source code is available, but I am afraid I haven't been able to make heads or tails out of it.

  • NullPointerException in ItemizedOverlay.getIndexToDraw

    - by lyricsboy
    I have a relatively simple MapActivity that I'm trying to make display a list of "camps" within a given map region. I've created a custom subclass of OverlayItem called CampOverlayItem, a custom ItemizedOverlay called CampsOverlay that returns CampOverlayItems, and of course a MapActivity subclass that populates the map. I'm pulling the overlay data from a database using an AsyncTask as created in my activity. The AsyncTask is triggered from a ViewTreeObserver.OnGlobalLayoutListener attached to the MapView. In the onPostExecute method of the AsyncTask, I create a new instance of my CampsOverlay class and pass it a list of the camps returned from the database (which are fetched in doInBackground). I then call: mapView.getOverlays().add(newOverlay); where newOverlay is the CampsOverlay I just created. All of this code runs without error, but when the Map tries to draw itself, I get a NullPointerException with the following stack trace: java.lang.NullPointerException at com.google.android.maps.ItemizedOverlay.getIndexToDraw(ItemizedOverlay.java: 211) at com.google.android.maps.ItemizedOverlay.draw(ItemizedOverlay.java:240) at com.google.android.maps.Overlay.draw(Overlay.java:179) at com.google.android.maps.OverlayBundle.draw(OverlayBundle.java: 42) at com.google.android.maps.MapView.onDraw(MapView.java:476) at android.view.View.draw(View.java:6274) at android.view.ViewGroup.drawChild(ViewGroup.java:1526) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.View.draw(View.java:6277) at android.widget.FrameLayout.draw(FrameLayout.java:352) at android.view.ViewGroup.drawChild(ViewGroup.java:1526) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.ViewGroup.drawChild(ViewGroup.java:1524) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.View.draw(View.java:6277) at android.widget.FrameLayout.draw(FrameLayout.java:352) at android.view.ViewGroup.drawChild(ViewGroup.java:1526) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1256) at android.view.View.draw(View.java:6277) at android.widget.FrameLayout.draw(FrameLayout.java:352) at com.android.internal.policy.impl.PhoneWindow $DecorView.draw(PhoneWindow.java:1883) at android.view.ViewRoot.draw(ViewRoot.java:1332) at android.view.ViewRoot.performTraversals(ViewRoot.java:1097) at android.view.ViewRoot.handleMessage(ViewRoot.java:1613) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4203) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:791) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) at dalvik.system.NativeStart.main(Native Method) Because it seems particularly relevant, here is the code for my ItemizedOverlay subclass: public class CampsOverlay extends ItemizedOverlay<CampOverlayItem> { private ArrayList<Camp> camps = null; public CampsOverlay(Drawable defaultMarker, ArrayList<Camp> theCamps) { super(defaultMarker); this.camps = theCamps; } @Override protected CampOverlayItem createItem(int i) { Camp camp = camps.get(i); CampOverlayItem item = new CampOverlayItem(camp); return item; } @Override protected boolean onTap(int index) { // TODO Auto-generated method stub return super.onTap(index); } @Override public int size() { return camps.size(); } } Does anyone have any idea what could be happening here? I've attempted to verify that everything I have control over is non-null. I can provide more code if necessary.
