Design suggestion: How to add programmatically add multiple (but indeterminate) 'Views' of the same class in an Android Activity -

i have problem not able solve.

an activity in android app needs build object has:

• a name
• a description
• zero or more items, described name, price, , other info

i have tried implement functionalities related 'items' in fragment. using fragment made sense me because have been able add logic (various checks on values) in fragment , have lighter activity. built activity

• edittext name
• edittext description
• an imageview '+' adding fragments
• a linearlayout hosting added fragments

i cannot use fragments because not kept during device rotation (i tried restore same views in linearlayout, same ids, not work).

how implement such functionality? not find example.
