[Paramjeet Singh Rana]

Actually what i am doing is giving user option to increment decrements   
products on all list-view items as shown in attached picture

     I am able to take listview item name,price to next screen but how should
     take the quantity value to next screen.
     the quantity updation code is done in the adapter of products
