Answer 1

Here is the error in the adapter:

convertView = ( RelativeLayout ) inflater.inflate( resource, null );

you have to check if convertView is null and only if it is - create a new View, otherwise use convertView given from method params

The pattern they're implementing it's called 'Holder Pattern', and It's used to make thing load faster when having a lot of Views in a ListView, anyway, you should chekout LRU Cache Android - API 12

They use a very efficient way to load images, first looking for them in the Cache Memory, if it's available in the Cache, we load from there, If not we load the Image and add it. To the cache.!
