I have a GridView displaying thumbnails using ImageViews. I am displaying a default image while the thumbnail images are being downloaded from the background(inspired from native applications) i.e. the getView() of my adapter class returns a default Bitmap first and then runs a background thread and replaces the default with actual later.
GridViews in iPhone application display a spinner (Animated GIF) instead of default image.
How can a similar thing be achieved in Android?
As Raj commented, get DroidFu's WebImageView here.

I am new to android, please help me to resolve this. I need to retrieve all images from gallery and show that like an animation using timer or thread. I Used below code get images from gallery how can I store the images in an array?My idea is to make animation using timer by picking images from an array and put in a single Imageview. but I could not store the images retrieved from gallery to an array. I could display it in gridview by using Imageadapter. In short I need to get n number of images from gallery and place it in an array and make animation using timer and single imageview.
String[] projection = {MediaStore.Images.Thumbnails._ID};
cursor=getContentResolver().query(MediaStore.Images.Thumbnails.INTERNAL_CONTENT_URI,
projection,null,null,MediaStore.Images.Thumbnails.IMAGE_ID);
You need to use AnimationDrawable and it's addFrame method. Here is the document.
You can try below link.
It will show how you can select multiple images from gallery;

I am currently doing a project which needs to load images in a listView with some text from web.I am using universal image loader library,every thing work fine images are loading perfectly without any problem, but my requirement is that if there is no image in a specfic url, i dont want to show that image view in the listview row.which is similer to the news stand app of google.
in the above screen of the newsstand app if there is no image the imageview is not shown and the text will fill to the total width of the cell or row in the listview.How can i achieve this requirement.i have goggled but did not get any right solution or clue to fix this issue,can any one give any snippet or any idea to sort out this issue.
Thank you
In your adapter, when you call the library to display the image, if there is no image url just set the visibility of your ImageView to GONE (and VISIBLE again when there is an url).
If you want to wait that the image is completely loaded to make the ImageView visible, you'll need to register a loading listener. See here.
I have a listView in which I have text and an image view Now the data is coming from the service in this case text is of some bytes but due to images size imageview populate after some time . for this I want to show loading symbol in in imageview so that in time of downloading user not say that the app is not able to show images. I have implemented all listActivity and adapters concepts and its working fine but the images take time due to which the imageview part shows black area . any help
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 don't know how to get the images what are available on the scree. I'm using imageview for the purpose of display the images on the screen.
Images will be changed randomly because i stored the images into array and images are in drawable. I want to know which image is displays on the screen at runtime.
thank u
When you change the image in the ImageView, hold onto the array index that you used in another variable.
I have a gallery that I use to display some ImageViews. I'd like to know which image in the gallery is currently highlighted/focused.
So far, setOnItemClickListener only fires if I actually click on the images. If I scroll through the images, a new image takes focus. I want to know which image that is.
How can I do this?
Get the images number in the list
Get the image (view) it self
