show products list in android with multicolumn custom layout

问题

I wanna show some products in my android application and I need it to be dynamic,

I need below requirements :

• show products in grid view (2, 3 or 4 columns depending on phone, tablet, portrait, landscape mode)
• each product has onclick event (to show detail of the product in another activity/fragment)
• each product on the grid should be from an xml layout (containing thumbnail image, title, price and so on)
• load more products on scrolling (load on scroll)
• load products from sqlserver database on the net using json (it can be done using adapters ...)

I should mention that I've searched for android libraries and I've found cardslib , but I can't understand how to combine these requirements with this library ! I know some of the requirements are easy to handle but I don't know how to have all of them together !

for clarifying the situation I've uploaded some pictures from a similar application:

thanks in advance for any solution.
