How to store dynamic data in local memory : Android

I have a product page with spinner. Spinner contains list of products. Dynamic views will be create by selecting product. No.of fields will be differ for each product. Fields may contain Edittext, Spinner. After user complete columns there is a save button to save filled details. Once user press the save button all fields value should be store in local.

I tried to save details in SQLite but sqlite only for structured datas. I am confused which local storage will be support for dynamic datas.

Please suggest any solution. Thanks in advance
