In my monodroid application I use universal image loader to display images on a list view .
Before displaying images i show a progress bar on images.
I wanna add an default images for when the download fails.
Is it possible?
This is the code that i display image with it:
ImageLoader = Com.Nostra13.Universalimageloader.Core.ImageLoader.Instance;
ImageLoader.DisplayImage(myobject.Images [0], imageView, Application.Options, newImageLoaderListener (progressbar));
This is a monodroid code.
Thanks.
Use ImageLoadingListener.onLoadingFailed() for that. Display your image in onLoadingFailed().

I want to do image downloading as whatsapp does as blur images appear and when we click on image clear image gets downloaded.I want to do the same kind of work in my android App.Can anyone suggest how to achieve this?
You can use any image loading liabrary(Picasso,Glide or UIL)
Firstly load image of low quality say if you using Picasso
Picasso.with(this).load("....").resize(100,100).into(imageViews);
than on click load full image.
I'm using android universal image loader for loading some image in a gridview. The thing is I want these images to have also a background image, I mean two images on top of each other, I looked at universal image loader to see if there are any options to set such image but I couldn't find any.
I'll appreciate if someone can help me with this.
Thanks very much
I have a grid view which shows some images loaded from a server. I use Universal image loader to load the images in the imageView. the problem is it takes time to load those images and I don't want their places to be empty. I want to show an image which is located in the assets of the app and then load the images from server on top of it.
I wanted to ask if you have any solutions to this problem.Thanks very much
Very generic way to use DisplayImageOptions is as
DisplayImageOptions displayImageOptions = new DisplayImageOptions.Builder()
.showImageOnLoading(R.drawable.placeholder_image).showImageForEmptyUri(0)
.resetViewBeforeLoading(true).cacheInMemory(true).cacheOnDisk(true)
.imageScaleType(ImageScaleType.IN_SAMPLE_INT).bitmapConfig(Bitmap.Config.RGB_565)
.delayBeforeLoading(100).displayer(new FadeInBitmapDisplayer(500)).build();
Here showImageOnLoading(R.drawable.placeholder_image) method is used to display a placeholder image until the real image is loaded. R.drawable.placeholder_image is the drawable you want to show as placeholder.

Here this I want:
In Android we called it lazy list..
this will help you to understood..
1.Lazy loading of images in ListView
2.http://www.technotalkative.com/android-asynchronous-image-loading-in-listview/
For Image issue :
Change in ImageLoader class (if Using Lazy List)
final int stub_id=R.drawable.ic_launcher; //change it to process image
Good Luck
Place a ProgressBar and keep the imageView over the ProgressBar.So the progress bar is visible when there is no image in the image view. Also use lazyList to load image.
You might want to check out Android Query. it's a library that also supports Asynchronous image loading and caching.

I want the image from url as it is without being sampled, but while using nostra's universal image loader the image is getting sampled. How am I supposed to avoid this is there any option to be included for this?
Enable imageScaleType(ImageScaleType.NONE) in display options (DisplayImageOptions).
