json parser images shown in lstview please help me - Android Discussion Boards

Thanks very much for your reply.it really helped me out.especially the tutorial from http://programmerguru.com/
i am very grateful for the help provided

You see how easy it is to find information through Google.

yeah it is actually easy but getting the right tutorial and trying to get it work is also another problem.Others post tutorials which are combersome for beginners like us

Well you have to do what the rest of us do, and search through the ones you find until you find one that suits your level of skill and knowledge. You can't expect other people to make that determination on your behalf.

yeah it is actually easy but getting the right tutorial and trying to get it work is also another problem.Others post tutorials which are cumbersome for beginners like us

Pls help
consider that i have created a database and i am users can view from the user interface.but the view created is too long such that users cannot keep scrolling.How can i add a search mechanism on that same page.to avoid scrolling.

Although my article is based on Xamarin / Visual Studio the same concepts still apply to Java / Eclipse.
