I'm developing an android application using SQLite Database. I have a itemList which user can enter food items into the List. I want to save the items of each listview seperately (one listview data in a line). And i'm using an Arraylist to store data which user enters into the System. Can someone help me to do this. Below i've posted my XML page and Java Class. Thanks in advance!! :)
