I'm facing some problems, so I though maybe someone could help me as I'm at dead end and have no idea how to fix this. So I'm creating an app, which use List Fragment with multiple (exactly 5) checkbox'es and 1 text view in a single row. So the first problem is: I want to check only one of 5 checkbox'es(that means if I check first one, then other(second,third,fourth,fifth box) shouldn't be checked and so on...). And the second and most important problem is that there will be like 10-20 rows, so as I scroll down/up some rows gets recycled and checked boxes become unchecked or randomly checked, so how I'm supposed to store data, so that checkbox'es which were checked won't be unchecked or randomly checked after scrolling up or down. Also onListItemClick do not work too :(
