Hello Friends!

I need to disable the items in list view until an in-app purchase transaction gets over. Once the transaction is over, the download activity need to start and download the contents of items in a queue.

1. Disable the items in the list view until the Android Market isPurchased result is OK.
2. Showup Progressbar in listview and update it as the download progresses.
3. Once a list item's download completes, the onClick of the item would lead to videoPlayer activity.
4. As download completes, each list item would get enabled.

Help me please how I can achieve this

Thanks
