Am pretty new to App development,

I have 2 radio buttons(radio group), and a Generate list"button" that i want to control a listview. I already created a list which has 20 items.

When you select radio button1=10, and click "generate list" button it should take me to a new screen with a list that has only "10 random" items

radio button and click "generate list" button it should take me to a new screen with a list that has only "15 random" items

how do i do that...?
