  • How can I make these images download on a seperate thread?

    - by Andy Barlow
    Hello!! I have the following code running on my Android device. It works great and displays my list items wonderfully. It's also clever in the fact it only downloads the data when it's needed by the ArrayAdapter. However, whilst the download of the thumbnail is occurring, the entire list stalls and you cannot scroll until it's finished downloading. Is there any way of threading this so it'll still scroll happily, maybe show a place holder for the downloading image, finish the download, and then show? Any help with this would be really apreciated. Thank-you kindly. Andy Barlow private class CatalogAdapter extends ArrayAdapter { private ArrayList<SingleQueueResult> items; //Must research what this actually does! public CatalogAdapter(Context context, int textViewResourceId, ArrayList<SingleQueueResult> items) { super(context, textViewResourceId, items); this.items = items; } /** This overrides the getview of the ArrayAdapter. It should send back our new custom rows for the list */ @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.mylists_rows, null); } final SingleQueueResult result = items.get(position); // Sets the text inside the rows as they are scrolled by! if (result != null) { TextView title = (TextView)v.findViewById(R.id.mylist_title); TextView format = (TextView)v.findViewById(R.id.mylist_format); title.setText(result.getTitle()); format.setText(result.getThumbnail()); // Download Images ImageView myImageView = (ImageView)v.findViewById(R.id.mylist_thumbnail); downloadImage(result.getThumbnail(), myImageView); } return v; } } // This should run in a seperate thread public void downloadImage(String imageUrl, ImageView myImageView) { try { url = new URL(imageUrl); URLConnection conn = url.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); Bitmap bm = BitmapFactory.decodeStream(bis); bis.close(); is.close(); myImageView.setImageBitmap(bm); } catch (IOException e) { /* Reset to Default image on any error. */ //this.myImageView.setImageDrawable(getResources().getDrawable(R.drawable.default)); } }

  • Any way to cache WAV files in IE?

    - by Dan Howard
    I'm seeing an issue with our web application. We have a few wave files which we can play (like ding.wav) and we have attempted to pre-load wave files but using Fiddler we're seeing that the WAV files are never cached like (js and css and image files). We always see an HTTP 200 instead of an HTTP 304. Any ideas on how to tell IE that it should cache wav files? We're inserting a div: <EMBED SRC='ding.wav' AUTOSTART='FALSE' HIDDEN='TRUE'>

  • How to check in which position (landscape or portrait) os the iPhone now?

    - by Mike Rychev
    I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation. If I write just - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) if (interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { //Code } else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) { //Code } } The view just goes crazy if user rotated the device before shaking. Is there a method to get iPhones current orientation?

  • Is it possible to use AnimateWindow with AW_BLEND when using a layered window?

    - by wkf
    I am displaying a window using UpdateLayeredWindow and would like to add transition animations. AnimateWindow works if I use the slide or roll effects (though there is some flickering). However, when I try to use AW_BLEND to produce a fade effect, I not only lose any translucency after the animation (per-pixel and on the entire image), but a default window border also appears. Is there a way to prevent the border from appearing?

  • Building a community photography site, where can I store my photos online?

    - by thanos panousis
    I am in the process of laying down the requirements for a photography community site. An important feature to investigate would be allowing more fotos/account than rival sites around my country's internet. What are the possibilities out there? Should I go for something like amazon S3, or is there anything that offers more image-related features? I am mostly interested in low price per GB (storage and transfer out).

  • Can a BufferedImage be written to file any format?

    - by ncoder
    Is it correct that if we have a BufferedImage object in java, we could potentially write it out in ANY format using ImageIO.write (if we have a Writer object for the same)? I tried writing a BufferedImage object into a jpg file, it outputted an empty image file however when i tried writing it in to a png file, it worked fine.

  • Is there any reason why we don't use subclasses of UIImageView ?

    - by gotye
    Hey everyone, I am currently trying to create a subclass of UIImageView in order to make it download its image from server asynchronously ;) I tried to do it by myself but I haven't gone very far yet :D Anyway, I looked around here and found this : AsyncImageDownload I had a look at the code and the first which springs to mind is : why subclassing a UIView and not a UIImageView ?!? Any thoughts ? Cheers mates, Gotye.

    How do I have the html loaded into my div from the .ajax render with jquery? the success function loads the HTML, but those elements do not show up as jQuery UI elements, just the static HTML types.

  • How can I embed a youtube video using variable widths/heights for a dynamic width web page?

    - by Dan Gayle
    I want to set a youtube video to 100% width so that it scales appropriately in a dynamic width column on a web page I am designing. The problem is that the height doesn't behave like the height of an image. Instead of scaling proportionately, it either collapses (if set to "auto" or left blank) or it scales seemingly random if set to a percentage. How can I get it to remain proportionate while still dynamic?
