[android-developers] Re: Selecting an radio button item in a multi page list

You're not really supposed to use the Views/ListView for such information, rather the Adapter (ListViews recycle views, the amount of children they have fits the amount items they can fit in the screen, not the amount of items in the backing store).

You can however still use the views if you also store the appropriate index in the view during onBind... it gets easier if you use the ViewHolder pattern since the ViewHolder object makes it easy to also store extra information (like that index you want).

Hi,

I have a list that is multiple pages long, and I'm trying to get the list index of the item that is selected using radio buttons. In onClickRadioButton() which I'm passing in my current View, I'm setting the myview as view.getParent() and the list index as ((ViewGroup) myview.getParent()).indexOfChild(myview).

The listindex is correct (starts from 0) when the list is 1 page long, but whenever I scroll down a list that's longer than a page, the list index gets reset to 0 based on the item that's on the top of the page. Does anyone know what I'm doing wrong? Does is have anything to do with my View and getParent()?

Thanks!
