Hi,
I have an application that does some calculations based on input to a form, which takes up about 1/2 a screen. I want to populate a ListView or some sort of table in the bottom half of the screen depending on the choices in the top half.

At the moment I'm getting static data output when I hit submit using the following:





This creates a nice, scrollable ListView in the bottom half of the screen which wasn't there when app loaded, but it's from a resource (xml array). I need it to take values I feed the ListView from an ArrayList after calculations from the form, or some other similar Java container which is empty to begin with.

1. Any sample code of populating a ListView NOT from "createFromResource"
2. Anyone recommend a better View for this rather than a ListView? I want it to be two equal columns, each column left justified with text only, and scrollable.

Thanks in advance
Iain

Update on my miserable attempts to fix this:

I tried to get the ListView showing a String Array using



instead of getting the data from an XML like (this works):



but I get the following error:

01-19 15:55:38.811: ERROR/AndroidRuntime(811): java.lang.RuntimeException: Unable to start activity ComponentInfo{bto.android/bto.android.PaceCalc}: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'

Can anyone help me work out what I'm doing wrong? Do I have to have the lv object created originally in onCreate method? This isn't needed for the second, resource populated method.

Really struggling, hope someone can help.

OK, cracked populating a ListView on the fly from an ArrayList rather than an XML file.

Will continue to think on a better, scrollable view than basic ListView.

Cheers
