  • How to get contacts in order of they upcoming birthdays?

    - by Pentium10
    I have code to read contacts details and to read birthday. But how do I get a list of contacts in order of they upcoming birthday? For a single contact identified by id I get details and birthday like this. Cursor c = null; try { Uri uri = ContentUris.withAppendedId( ContactsContract.Contacts.CONTENT_URI, id); c = ctx.getContentResolver().query(uri, null, null, null, null); if (c != null) { if (c.moveToFirst()) { DatabaseUtils.cursorRowToContentValues(c, data); } } c.close(); // read birthday c = ctx.getContentResolver() .query( Data.CONTENT_URI, new String[] { Event.DATA }, Data.CONTACT_ID + "=" + id + " AND " + Data.MIMETYPE + "= '" + Event.CONTENT_ITEM_TYPE + "' AND " + Event.TYPE + "=" + Event.TYPE_BIRTHDAY, null, Data.DISPLAY_NAME); if (c != null) { try { if (c.moveToFirst()) { this.setBirthday(c.getString(0)); } } finally { c.close(); } } return super.load(id); } catch (Exception e) { Log.v(TAG(), e.getMessage(), e); e.printStackTrace(); return false; } finally { if (c != null) c.close(); }

  • XML Table layout? Two EQUAL-width rows filled with equally width buttons??

    - by Oliver Goossens
    Hi heres a part from my XML for LAND format: <TableLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="center" android:stretchColumns="*"> <TableRow> <Button android:id="@+id/countbutton" android:text="@string/plus1"/> <Button android:id="@+id/resetbutton" android:text="@string/reset" /> </TableRow> </TableLayout> And now what I dont get - the WIDTH of one row and also of the button depends on the TEXT inside the button. If the both texts are equaly long lets say : TEXT its ok - the table half is in the middle of the screen. But if they have different size - lets say "A" and "THIS IS THE LONG BUTTON" the CENTER of the table isnt in the middle of the screen anymore and so the buttons are not equally width... Cant find any solution... Please advise... Thank you Oliver Goossens

  • Admob ads will not display when placed inside a tabview

    - by smith324
    I've been trying to get my ads to display in this type of layout. Tabs - LinearLayout - ListView - header. The header is set via addHeaderView and is displaying normally. If I were to move the ads anywhere else they display normally (so its not a setup issue). Using ads in the header of a listview works fine in my other projects. So this seems to be a very specific problem, the ads simply refuse to display when placed in the header of a listview inside a tabhost. My logs show no activity from admob at all. There is either a bug here or limitation of the sdk. Does anyone have any experience or insight into this issue? EDIT I found the solution. It actually had to do with padding that was in the root of my Tabview. For more checkout my answer here

  • Variable cannot be resolved

    - by Devel
    Hi, I am trying to create an item list, diffrent for each i and j variable. My code is: if (i == 0) { if (j == 0) { final CharSequence[] items = {"4:45", "5:00"} } else if (j == 1) { final CharSequence[] items = {"4:43", "4:58"} } else if (j == 2) { final CharSequence[] items = {"4:41", "4:56"} } else { final CharSequence[] items = {"4:38", "4:53"} } ... new AlertDialog.Builder(this) .setTitle("Hours") .setItems(items, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialoginterface, int i) { // getStation(i); } }) .show(); } I get an error in the line .setItems(items,: items cannot be resolved I think that the compiler thinks that the CharSequence[] items may not be initialised or something... How can I make this programme run?

    - by rotary_engine
    Trying to add an image to a RichTextBox progamatically from a Stream. The image displays in the text box, however when reading the Xaml property there is no markup for the image. private void richTextBox3_Drop(object sender, DragEventArgs e) { if (e.Data.GetDataPresent(DataFormats.FileDrop)) { FileInfo[] files = (FileInfo[])e.Data.GetData(DataFormats.FileDrop); using (Stream s = files[0].OpenRead()) { InlineUIContainer container = new InlineUIContainer(); BitmapImage bmp = new BitmapImage(); bmp.SetSource(s); Image img = new Image(); img.SetValue(Image.SourceProperty, bmp); container.Child = img; richTextBox3.Selection.Insert(container); } } } private void Button_Click_1(object sender, RoutedEventArgs e) { // this doesn't have the markup from the inserted image System.Windows.MessageBox.Show(richTextBox3.Xaml); } What is the correct way to insert an image into the RichTextBox at runtime so that it can be persisted to a data store? In the Xaml property.

  • Stop All Started Services on App Close / Exit

    - by Rad The Mad
    Is it possible to stop all started services when the user hits the Home Button? I use: startService(new Intent(ClassName.this, ClassName2.class)); stopService(new Intent(ClassName.this, ClassName2.class)); This means I will have to somehow add the 'stopService()' for 7+ of my app classes I've researched this topic and I think there's 'onTerminate' but still not sure how this should be implemented. Any help or hints would be appreciated! Thanks!

  • Dialog, LinearLayout, ScrollView size issues

    - by Sean
    I'm building a dialog class which inherits from Dialog, and all internal UI is programmatic. It's structured in the following way: Dialog +LinearLayout ++TextView ++ScrollView +++LinearLayout ++++ListView Unfortunately, when I show() the Dialog, it's too short. I'd like it to maximize and cover as much of the screen as possible, but only when there are enough items in the ListView to warrant it. I haven't found my answer in the docs, and I haven't been able to get it to work by setting WRAP_CONTENT as layout parameters, or setting heights manually. What is the proper way to approach this? Thanks, Sean

  • ListAdapter to modify the datasource (which is an arraylist)

    - by dusker
    Hi Everyone, here's a problem that i've run into lately: I have a listview with a custom adapter class, the adapter takes in a listview and populates the listview with elements from it. Now, i'd like to have a button on each row of a listview to remove the item from it. How should i approach this problem? Is there a way to remotely trigger a method in the activity class and call notifydatachanged() method on the adapter to refresh the listview? thanks in advance for your help and some code snippets if possible best regards peter

  • iPhone SDK background thread image loading problem

    - by retailevolved
    I have created a grid view that displays six "cells" of content. In each cell, an image is loaded from the web. There are a multiple pages of this grid (the user moves through them by swiping up / down to see the next set of cells). Each cell has its own view controller. When these view controllers load, they use an ImageLoader class that I made to load and display an image. These view controllers implement an ImageLoaderDelegate that has a single method that gets called when the image is finished loading. ImageLoader does its work on a background thread and then simply notifies its delegate when it is done loading, passing the image to the delegate method. Trouble is that if the user moves on to the next page of grid content before the image has finished loading (releasing the GridCellViewControllers that use the ImageLoaders), the app crashes. I suspect that this is because along the line, an asynchronous method finishes and attempts to notify its delegate but can't because it's been released. Here's some code to give a better picture: GridCellViewController.m: - (void)viewDidLoad { [super viewDidLoad]; // ImageLoader _loader = [[ProductImageLoader alloc] init]; _loader.delegate = self; if(_boundObject) [_loader loadImageForProduct:_boundObject]; } //ImageLoaderDelegate method - (void) imageDidFinishLoading: (UIImage *)image { [_imgController setImage:image]; } ProductImageLoader.m - (void) loadImageForProduct: (Product *) product { // Get image on another thread [NSThread detachNewThreadSelector:@selector(getImageForProductInBackground:) toTarget:self withObject:product]; } - (void) getImageForProductInBackground: (Product *) product { NSAutoreleasePool *tempPool = [[NSAutoreleasePool alloc] init]; HttpRequestLoader *tempLoader = [[HttpRequestLoader alloc] init]; NSURL *tempUrl = [product getImageUrl]; NSData *imageData = tempUrl ? [tempLoader loadSynchronousDataFromAddress:[tempUrl absoluteString]] : nil; UIImage *image = [[UIImage alloc] initWithData:imageData]; [tempPool release]; if(delegate) [delegate imageDidFinishLoading:image]; } The app crashes with EXC_BAD_ACCESS. Disclaimer: The code has been slightly modified to focus on the issue at hand.

  • AVFoundation buffer comparison to a saved image

    - by user577552
    Hi, I am a long time reader, first time poster on StackOverflow, and must say it has been a great source of knowledge for me. I am trying to get to know the AVFoundation framework. What I want to do is save what the camera sees and then detect when something changes. Here is the part where I save the image to a UIImage : if (shouldSetBackgroundImage) { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); // Create a bitmap graphics context with the sample buffer data CGContextRef context = CGBitmapContextCreate(rowBase, bufferWidth, bufferHeight, 8, bytesPerRow, colorSpace, kCGBitmapByteOrder32Little | kCGImageAlphaPremultipliedFirst); // Create a Quartz image from the pixel data in the bitmap graphics context CGImageRef quartzImage = CGBitmapContextCreateImage(context); // Free up the context and color space CGContextRelease(context); CGColorSpaceRelease(colorSpace); // Create an image object from the Quartz image UIImage * image = [UIImage imageWithCGImage:quartzImage]; [self setBackgroundImage:image]; NSLog(@"reference image actually set"); // Release the Quartz image CGImageRelease(quartzImage); //Signal that the image has been saved shouldSetBackgroundImage = NO; } and here is the part where I check if there is any change in the image seen by the camera : else { CGImageRef cgImage = [backgroundImage CGImage]; CGDataProviderRef provider = CGImageGetDataProvider(cgImage); CFDataRef bitmapData = CGDataProviderCopyData(provider); char* data = CFDataGetBytePtr(bitmapData); if (data != NULL) { int64_t numDiffer = 0, pixelCount = 0; NSMutableArray * pointsMutable = [NSMutableArray array]; for( int row = 0; row < bufferHeight; row += 8 ) { for( int column = 0; column < bufferWidth; column += 8 ) { //we get one pixel from each source (buffer and saved image) unsigned char *pixel = rowBase + (row * bytesPerRow) + (column * BYTES_PER_PIXEL); unsigned char *referencePixel = data + (row * bytesPerRow) + (column * BYTES_PER_PIXEL); pixelCount++; if ( !match(pixel, referencePixel, matchThreshold) ) { numDiffer++; [pointsMutable addObject:[NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH - (column/ (float) bufferHeight)* SCREEN_WIDTH - 4.0, (row/ (float) bufferWidth)* SCREEN_HEIGHT- 4.0)]]; } } } numberOfPixelsThatDiffer = numDiffer; points = [pointsMutable copy]; } For some reason, this doesn't work, meaning that the iPhone detects almost everything as being different from the saved image, even though I set a very low threshold for detection in the match function... Do you have any idea of what I am doing wrong?

  • Action Item shown only in Landscape?

    - by roboguy12
    I was just wondering if it were at all possible for an Action Bar icon to only be shown when the device is in landscape mode? In portrait I have an onscreen button for a certain task, but in order to take advantage of all of the screen-space in landscape, that button won't fit. So I was wondering if I could put it in the Action Bar, but it would only be necessary when the device is in landscape. Thanks!

  • How to set clickable and highlightable a ViewStub?

    - by Pentium10
    I have ViewStubs in my layout. If I set clickable and implement the OnClickListener this does work only on the root of the element. But the layout holds parent elements, and when I click on those the click is not recognized. How do I make a full row/view of ViewStub as whole to be clickable and highlightable like a ListView elements? Also what do I have to add to get that orange highlight?

  • display wait gif until image is fully loaded

    - by Dimitris Baltas
    Most popular browsers, while rendering an image, they display it line-by-line top-to-bottom as it loads. I have a requirement that a wait gif should be displayed while the image is loading. When the image is fully loaded then it should be displayed instead of the wait gif. If it helps, the site is http://farros.gr, main image: /images/bg.jpg and the div containing the image is named #main-content-image.

  • Best way to pass image to server?

    - by Chris
    I have an SL3 application that needs to be able to pass an image to the server, and then the server will generate a PDF file with the image in it, and display it to the user. What I already have in place are the following: (1) Code to convert image to byte array (2) Code to generate PDF file with image The main problem that I am running into is the following: In order to bypass the pop-up blocker, which is a requirement for my application, I am using the following code: var button = new NavigationButton(); button.NavigateUri = new Uri("http://localhost:3616/PrintReport.aspx?ReportIndex=11&ActionType=Get&ReportIdentifier=" + reportIdentifier.ToString() + ""); button.TargetName = "_blank"; button.PerformClick(); Initially, I would pass the image to a WCF web service (as a byte array), and then "navigate" to the ASP.NET page that would display the report. However, if I do this, then I can not use my custom HyperlinkButton class, and, certain browsers, including Safari, will block a new window from opening up. Therefore, it appears that the only option is to use the HyperlinkButton class. What I need to be able to do is to somehow pass the image, as a byte array or some other data type, to the server, such that it can temporarily store the image, even if it is in a server variable, and then immediately retrieve it when I navigate to the PrintReport.aspx page. If I upload the image to an ASP.NET form and then use the HyperlinkButton class to navigate to the PrintReport page, it doesn't work, as the app navigates to the PrintReport page before the system has finished uploading the image. I can't pass it to a web service, as that would require that I navigate to the PrintReport.aspx page in the callback code of the web method that I would be passing the image to, and the HyperlinkButton will not allow that, based on security rules. Any help or ideas would be appreciated. Thanks. Chris

  • Deleting items from a ListView using a custom BaseAdapter

    - by HXCaine
    I am using a customised BaseAdapter to display items on a ListView. The items are just strings held in an ArrayList. The list items have a delete button on them (big red X), and I'd like to remove the item from the ArrayList, and notify the ListView to update itself. However, every implementation I've tried gets mysterious position numbers given to it, so for example clicking item 2's delete button will delete item 5's. It seems to be almost entirely random. One thing to note is that elements may be repeated, but must be kept in the same order. For example, I can have "Irish" twice, as elements 3 and 7. My code is below: private static class ViewHolder { TextView lang; int position; } public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.language_link_row, null); holder = new ViewHolder(); holder.lang = (TextView)convertView.findViewById(R.id.language_link_text); holder.position = position; final ImageView deleteButton = (ImageView) convertView.findViewById(R.id.language_link_cross_delete); deleteButton.setOnClickListener(this); convertView.setTag(holder); deleteButton.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.lang.setText(mLanguages.get(position)); return convertView; } I later attempt to retrieve the deleted element's position by grabbing the tag, but it's always the wrong position in the list. There is no noticeable pattern to the position given here, it always seems random. // The delete button's listener public void onClick(View v) { ViewHolder deleteHolder = (ViewHolder) v.getTag(); int pos = deleteHolder.position; ... ... ... } I would be quite happy to just delete the item from the ArrayList and have the ListView update itself, but the position I'm getting is incorrect so I can't do that. Please note that I did, at first, have the deleteButton clickListener inside the getView method, and used 'position' to delete the value, but I had the same problem. Any suggestions appreciated, this is really irritating me.
