Sorry... Didn't notice your ArrayAdapter constructor... You have more the correct NUMBER of arguments, but you are specifying the layout... not the id of the textview.
If your textview looks like this: <textView android:id="@+id/my_textView" /> then the second parameter in your constructor should be R.id.my_textView Thanks, Justin Anderson MagouyaWare Developer http://sites.google.com/site/magouyaware On Thu, Mar 22, 2012 at 11:13 AM, Justin Anderson <[email protected]>wrote: > Did you bother to look at the documentation?
