in android how to develop an hotel bill application with different categories of items?
first we have to create 3 or 4 buttons showing categories and another button for viewing the bill page consists of selected items,
on the next page we have place different items and their prices by using check-boxes for the different categories
and then there will be two buttons in the bottom of the items pages showing submit and clear bill options .if we click submit button then the billing page has to be generated and if we click cancel button then selected data has to be erased ?
i've been trying to do but cant get it any one can help me from this situation
