Need Help with Dynamic Usage of Gallery view

Postby northernguy69 » Wed Dec 09, 2009 8:21 pm

I'm fairly new to android development and I can't seem to figure out how to do a certain task with the Gallery view. Basically, i'm trying to get json data from a url which will provide me with an ids and a urls to images.

An example of the sample return json string would be as follows:


[{"image_id":445, "image_url":"http://www.domain.com/image1.jpg"}, {"image_id":446, "image_url":"http://www.domain.com/image2.jpg"}]



- How could i dynamically build the Gallery with the image URL's obtained from the JSON data?
- For each image in the Gallery, how can i give it the "image_id" value from the json data so that when i click on that image, i can start a new activity and pass it the necessary image_id value via intent.putExtra("image_id", "445"); ?

I appreciate any help you can provide me with!

Thanks
Al

building and parsing json strings:

loading images from the web
gallery_with_remote_images-t769.html

associate (and getting) additional informations to the view (ImageView)
Code: Select all
http://developer.android.com/reference/android/view/View.html#setTag(java.lang.Object)
http://developer.android.com/reference/android/view/View.html#getTag()


sorry... it's only a list of links. the full answer would be a great tutorial :)

bye ;)
