  • Andriod Spinner not displaying list items.

    - by user300339
    I think I am going crazy right now. I am trying to create a spinner populated by a datatable but for some reason the dropdown list items text is not being displayed. I have looked all over and have seen other posts with people having this same problem. Can anyone help?? speciesList = (Spinner) findViewById(R.id.speciesList); spinnerCursor = nsfdb.fetchAllSpecies(); startManagingCursor(spinnerCursor); //String []cArrayList = new String[]{"dog", "cat", "horse", "other"}; String[] from = new String[]{"species"}; int[] to = new int[]{R.id.text1}; SimpleCursorAdapter locations = new SimpleCursorAdapter(this, R.layout.loc_row, spinnerCursor, from, to); locations.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); speciesList.setAdapter(locations); The spinner gets created just fine and is populated with 4 items but whenever I click on the spinner I see 4 items with no text and just radiobuttons. If I select any of them I am getting the correct selected item value but there is just no data displayed.

  • Puzzled with nib files...

    - by Michael
    I know nib files are serialized objects and they have owner, outlets to make connections. Using XCode Navigation window template I created application, which in its order created 2 nib files - MainWindow and SecondView. I can't understand how MainWindow is referring to SecondView, there is no connection between those two as far as I can see. SecondView's owner is UIViewController and in MainWindow there is a navigation tab which is also UIViewController. But how they are connected in IB I can't understand... Also I don't understand who is instanciating MainWindow's owner object and where that object is being kept, where is the variable which is UIApplication myApp = [[UIApplication alloc] init]. If I create 10 nib files with UIViewController owner, who will trigger their deserialization? If some class is nib file's owner, what is the essential responsibilities of that class? Is it deserializing nib file into memory? Sorry for unorganized questions, I've been reading numerous articles and docs about nib files, but it is still confusing.

    - by Mickey Shine
    I am just wondering is there a way to convert nib/xib file to ojbective C code? I just want to find the equivalent code to the nib/xib file (I've tried nib2objc, seems the result is not what I am after). Actually I want to compile this example http://developer.apple.com/iphone/library/samplecode/TableSearch/index.html without nib/xib file (I want it exactly the same with original), any idea about doing this?

  • Prevent sqlite INJECTION ATTACKS on your own iPhone?

    - by Bonnie
    I always take precautions regarding SQL INJECTION ATTACKS when data is saved between someone's iPhone and a remote database on the cloud. But is it also necessary to do the same... when just saving data (using sqlite) from someone's cell phone, to a database that's just on their own phone? What's the worse they can do? Delete their own data (or tables) on their own phone? (If they really try hard enough.) Thanks.

  • A little bit more complicated multiview App for Iphone

    - by Thomas Losert
    Hi, i'm new to iphone development. I spend several days by looking for how write muliview app for an Iphone OS. I found how to switch the diferent views without navigation hierarchy (in this article). It's great, but i want more complicated function. For example, i have three diferent views (view 1 - 3) and i can switch between them with technique from link 1. It works fine. My question is: How can i put UITabBarController on view 2, that shows own subviews (tabView 1 - 3) and how put UINavigationController on view 3, that shows own subviews (navView 1 - 2)? The reslut should look like that, one main view (view 1) with two buttons (for example), which switch me to "window" with UiTabBarController or UINavigationController. I found only tutorials, where UITabBarController was a first controller class, that shows directly from AppDelegate (something like default Xcode predefined scenarios). Thanks for your helpfull answer, or i will be crazy soon:).

    - by Bodie
    I'm trying to scrape the entire iTunes App Store so that I can store it in a database for a project I'm working on. I'm having a hard time finding the best way to do this. I know there are ways to get specific information about price changes but I can't find anything that describes how to scrape the entire app store. Any additional info is appreciated.

  • What is the difference between these two different lines of Objective-C, and why does one work and n

    - by jrtc27
    If I try and release tempSeedsArray after seedsArray = tempSeedsArray , I get an EXEC_BAD_ACCESS, and Instruments shows that tempSeedsArray has been released twice. Here is my viewWillAppear method: - (void)viewWillAppear:(BOOL)animated { NSString *arrayFilePath = [[NSBundle mainBundle] pathForResource:@"SeedsArray" ofType:@"plist"]; NSLog(@"HIT!"); NSMutableArray *tempSeedsArray = [[NSMutableArray alloc] initWithContentsOfFile:arrayFilePath]; seedsArray = tempSeedsArray; NSLog(@"%u", [seedsArray retainCount]); [seedsArray sortUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; [super viewWillAppear:animated]; } seedsArray is an NSMutableArray set as a nonatomic and a retain property, and is synthesised. However, if I change seedsArray = tempSeedsArray to self.seedsArray = tempSeedsArray (or [self seedsArray] = tempSeedsArray etc.), I can release tempSeedsArray. Could someone please explain simply to me why this is, as I am very confused! Thanks

    After going into Edit mode, moving a cell, and leaving edit mode, i am left with one extra cell sitting on top of its duplicate cell while still in edit mode. The problem has to be somewhere in here: - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath { NSMutableArray *array = [[fetchedResultsController fetchedObjects] mutableCopy]; id objectToMove = [[array objectAtIndex:sourceIndexPath.row] retain]; [array removeObjectAtIndex:sourceIndexPath.row]; [array insertObject:objectToMove atIndex:destinationIndexPath.row]; [objectToMove release]; for (int i=0; i<[array count]; i++) { [(NSManagedObject *)[array objectAtIndex:i] setValue:[NSNumber numberWithInt:i] forKey:@"userOrder"]; } [array release]; } Any guidance greatly appreciated!

  • How to change font size in a pickerview?

    - by user183804
    I'm fairly new to iPhone programming and am trying to implement a double-component PickerView. At this point the picker works fine in terms of taking user input, created with Interface Builder. However, I need to change the font size to accommodate the text length in each column. I very much would appreciate any link to a straightforward method to creating a multi-component picker with an adjustable font size. Seems like it is not possible if Interface Builder is used to create the picker. So far I have not found any code links that address this issue in detail. Thanks in advance.

  • Does Android AsyncTaskQueue or similar exist?

    - by Ben L.
    I read somewhere (and have observed) that starting threads is slow. I always assumed that AsyncTask created and reused a single thread because it required being started inside the UI thread. The following (anonymized) code is called from a ListAdapter's getView method to load images asynchronously. It works well until the user moves the list quickly, and then it becomes "janky". final File imageFile = new File(getCacheDir().getPath() + "/img/" + p.image); image.setVisibility(View.GONE); view.findViewById(R.id.imageLoading).setVisibility(View.VISIBLE); (new AsyncTask<Void, Void, Bitmap>() { @Override protected Bitmap doInBackground(Void... params) { try { Bitmap image; if (!imageFile.exists() || imageFile.length() == 0) { image = BitmapFactory.decodeStream(new URL( "http://example.com/images/" + p.image).openStream()); image.compress(Bitmap.CompressFormat.JPEG, 85, new FileOutputStream(imageFile)); image.recycle(); } image = BitmapFactory.decodeFile(imageFile.getPath(), bitmapOptions); return image; } catch (MalformedURLException ex) { // TODO Auto-generated catch block ex.printStackTrace(); return null; } catch (IOException ex) { // TODO Auto-generated catch block ex.printStackTrace(); return null; } } @Override protected void onPostExecute(Bitmap image) { if (view.getTag() != p) // The view was recycled. return; view.findViewById(R.id.imageLoading).setVisibility( View.GONE); view.findViewById(R.id.image) .setVisibility(View.VISIBLE); ((ImageView) view.findViewById(R.id.image)) .setImageBitmap(image); } }).execute(); I'm thinking that a queue-based method would work better, but I'm wondering if there is one or if I should attempt to create my own implementation.
